Annotated_Summary


A preferred idea of the current magnetic locking system is being used to releasably lock two components together. In the first embodiment, the locking system contains a ferro-magnetic component that is linked to the first embodiment that is also made of a ferro-magnetic material. Subsequently, the second embodiment has a housing attached to it and is positioned close to the other ferro-magnetic component. This housing has two blocks that will be sandwiched together to make a block halfway. In addition, there is a gap in it where a permanent magnet is placed and can rotate freely. This locking system comprises a switch mechanism that operates in conjunction with the previously mentioned magnet and the housing. It is constructed and arranged accordingly to the housing and the permanent magnet to initiate the ‘’on’’ and ‘’off’’ operation of the locking system. This is achieved by attracting the ferro-magnetic material. In another concept, the housing and permanent magnet is replaced by an electromagnet where it is associated with the second component. The electromagnet is wired to a power supply and is controlled by a switch. When it is activated, the electromagnet produces a strong magnetic force on the ferro-magnetic component that is connected to the first component, Jie Lui. (2010).

Tech_Report Draft 1

Background


According to Garmin website (Garmin, n.d -a) the Garmin Edge 830 is not only a bicycle navigation device but it also provides performance monitoring for cyclist training and recovery. One reason why cyclists do not want to use their phones for navigation is that it drains the battery of the phone, and when the cyclist receives a phone call, the screen is changed to reflect the details of the caller, taking precedence over the navigation screen. ‘ This is the reason why a ”customer wants a product that fits one purpose, something they can put up on their big screen”(Taub, 2015).


Garmin ( n.d. -b) also states that there are three different mounts that the Edge 830 can provide. The standard mount included in the box has two rubber straps that are used to strap around the bike stem connected to the rubber disc which holds the Garmin Edge. 


The second and third mounts provided by Garmin are external mounts that need to be bought, both of the mounts use screws to hold the mounts in place which also holds the Garmin edge more securely. Although being more secure, the cost of it is much more expensive than other competitive companies that provide mounts at a lower price which also has a basic mounting mechanism.
According to cyclingweekly website (Obridgewood, 2018), after a period of time the Garmin mounting system wears off and the plastic on the back of the unit worn down over time which can cause the device to vibrate during cycling. Thus, this causes the device to be less secure. 
Also, Semantik (2013) suggested in the Online Forum Post ‘Lost my Garmin Device-can Garmin help?’ that once the provided o-rings stretched over the stem over long periods of time, it will loosen and will not fit as snug anymore. The great divide (2013) also added that even after you have lost your device you might not be able to find the device even if you logged in to your Garmin account.
Due to the problems with the current mount offered by Garmin, customers may search for alternative mounts from competitor companies/outside sources such as SRAM which provides a similar mounting system at a lower cost compared with the other three mounts provided by Garmin. Therefore, our team has proposed a secure locking mechanism mount that prevents the Garmin Edge from dropping out from the handlebars of your bicycle will help not only in providing a secure mount it also prevents theft of your Garmin Edge when you forget to remove it from your bicycle this additional feature will be unique to the other mounts available in the market.


To improve the problems faced by Garmin, our group came up with an idea to counter the mounting problem. The idea proposed is to make the device to be mounted on the bike with a magnetic lock that is easily removable by the owner yet prevents the device from being easily stolen. 


Problem statement


The basic o-ring mount provided in the box by Garmin is not secure enough to prevent it from falling out of the bicycle. Moreover, once it is lost you might not be able to find it. Although Garmin does provide external accessories for mounting the Garmin Edge it costs too much for just providing basic mounting mechanisms.


Purpose


This report proposes that the Garmin mount design team to implement a locking mechanism that not only allows the cyclist to mount their Garmin Edge but also prevents theft even if the cyclist forgets to remove it from the bicycle.


Modification


The current mount for Garmin Edge only provides a basic mechanism to hold the device. Implementing an improved mount which includes a magnetic lock where only the cyclist has the magnetic key. This allows the cyclist to remove Garmin Edge easily with the magnetic key as well as preventing theft of the device. 


Magnetic Lock


Firstly, one key enhancement to the mounts provided by Garmin will be to change the way the device is mounted from pushing it into the mount followed by twisting to the upright position. This is then replaced with using a key to align the magnet then placing the device on top of the mount after the key is removed the magnets will then hold Garmin Edge in place. This key consists of magnets placed at specific regions making each key unique therefore more secure preventing theft. 


Universal mount


Another key addition for the mount is that it can be mounted to other means of transportation such as motorcycles. Currently, Garmin has three different types of mount that are only suitable to be mounted on bicycles. By having a universal mount, users can save the cost of buying mounts as they can use the mount for both bicycles and motorcycles.


Choice of material
Another proposed modification on the mount is to revise the material used to manufacture it. Since the mount will be exposed to various weather conditions, it is advised that the material is relatively light proof. Ultraviolet light from the sun causes plastics to go through a process called photodegradation where the plastics disintegrate (Chandler, 2012). Being exposed under the sun for long hours will deteriorate the plastic and lose its durability and strength. Hence, it is not wise to have the mount to fail during the cycling routine. 
Combining into a single unit
A final modification that would be beneficial for the user is by combining the Garmin Edge and the mount itself together as one unit. Therefore, there is no need for the user to keep on removing the device every time they are done with their cycling exercise. If the previously mentioned modifications have been implemented, it would not be a problem for the device to be left alone. Firstly, the device will be well secured and locked with the aid of the new magnetic locking system. Secondly, the mount can withstand various weather conditions and that the Garmin Edge itself is already waterproof. 



Benefits


The risk of theft will be greatly reduced with the additional safety features being implemented on the Garmin mount. Besides that, the additional features also provide a better choice of material that can protect the device under harsh conditions and helps the user to save the cost of buying mounts as it is not only restricted to be used for bicycles but also other transportation as well. Lastly, by combining the Garmin Edge and the mount itself together as one unit would be a great benefit for the user as there is no need for the user to keep on removing the device every time they are done with their cycling exercise.


Evaluation


Although the magnetic lock, universal mount, better material and combination of the device into a single unit do provide their benefits, the team foresees a few challenges that might be faced.


To implement all of the proposed modifications, a substantial amount of research and development (R&D) will be required especially for the magnetic lock system and material choice, increasing the R&D costs. This greatly raises the overall price of the Garmin Edge and the mount, which may discourage potential customers as the price may be higher than most mounts currently out on the market. Additionally, in the event that a customer loses their magnetic key required to unlock and remove their device from the mount, it will require either Garmin to send personnel down to where the customer is or the customer has to transport their entire bicycle to a Garmin service centre to remove the device using a master key and purchase a replacement key.


However, there are many designs on the market that Garmin can reference and there is publically available materials research that can be found easily. This ensures a simpler, less time consuming and more cost-efficient research and development for Garmin. Although it is the responsibility of the customers to keep track of their magnetic key, the creation of a master magnetic key is not difficult and should already be included in the initial prototyping.


Weighing the pros and cons, the team concludes that the potential benefits outweigh the problems Garmin may face. Thus the team trusts that sales will be boosted if Garmin embraces the ideas and improves the ease of mounting and the security of the device as these modifications are long term benefits.


Methodology


The relevant information for the completion of this report was referenced from secondary research sources.


Secondary Research


Detailed research was done on the device and mount, their shortcomings, and the potential modifications in order to develop an effective design proposal. The team used official sites from Garmin in addition to secondary resources to support the research. The Garmin websites were used to comprehend the main features of the devices as well as the mounting process. Pros and cons, as well as potential modifications needed to resolve the problems, were found using secondary sources. Secondary sites were also referenced to present applicable issues to improve the reliability of the proposal.


Conclusion

In conclusion, modification into a magnetic lock, universal mount, weather-resistant material and combination into a single unit should be implemented to make the Garmin Edge more secure. These modifications will enable an easier mounting process while ensuring the security of the device. If Garmin applies these modifications to their current mounts and devices, the mount will be simple to install and users can leave their device on their bicycles with the ease of mind that it will not be stolen. This will give Garmin an edge over its competitors.

Design Summary Analysis Final


Seabin Using Plastics to Fight Plastics

According to Seabin Using Plastic to Fight Plastic (2019), Seabin Project states that microplastics and microfibres are one of the greatest threats to the marine ecosystem. They collect organic pollutants faster than inorganic particles where marine animals will mistake them as food. The article states that microplastics and microfibres are plastics pieces that are smaller than 5 mm. The Seabin Project mentions that Seabin Technology captures and removes all surrounding debris and microplastics. A study was conducted and observed that Seabin was able to remove finer plastics, of sizes 2 to 5 mm in diameter. Mantra trawl is the standard sampling method where a special net is dragged behind a boat. The article mentions that the physical traits of the samples are near identical and that both mantra trawl and Seabin are effective in sampling microplastics. As explained in the article, the reason why Seabin is a preferred method is that it is reliable, time-saving and inexpensive.

One of the reasons why Seabin is the desired method is its reliability. As mentioned in Seabin Floating trash Collector, One Clarion states that not only plastic wastes are gathered, but also stormwater debris which comes from the city’s water system are captured and contained as well. It further explained that by doing so, Seabins assist communities in clearing the pollutants and keeping the environment clean. Most of the residues that got caught in the catch bags are items like plastic bags, cigarette butts, fishing gear and many more. These pollutants are causing marine life to be at risk. In the statistics shown in Plastic Ain’t So Fantastic (2020), Ocean Crusaders educates us that plastics take a long time to degenerate and that close to a hundred thousand marine animals died due to plastic entanglement and that these are only the ones found. Who knows that there are more out there in the waters that have yet to be discovered?  

Another reason that makes Seabin a chosen method is because of how timesaving it is. In the first article, One Clarion also mentions that Seabins consistently pumps the collected trash-filled water from the water bodies and filters the water through reusable catch bags continuously all day for the whole year round if the Seabins are maintained properly by the city. According to their statistics, these floating bins filter out 3.9 kilograms of debris after pumping 25 litres of water per hour each day. All the user left to do is diligently change the catch bags when its full to ensure that the Seabins are in optimal working condition.

Another factor that made Seabin recognisable is how relatively cheap it is. A mentioned in Marina Enlist Floating Garbage Collector to Clean Waterways. (2019), Mia Overton states that each Seabin unit costs about $4000 (US), which is quite a reasonable price. Operating all day long at less than $3 a day, it is way better than having human labour to do this job. Profit is not the aim of this project but to solve this crisis is the main agenda. Hence, Seabin has been working under a business model since 2015 where half of the profit they made is used for non-profit activities like creating awareness on this as they believe that education is the key to overcome this situation.

Draft 1 Summary

Seabin Article
According to Seabin Project (2019), microplastics and microfibres are now considered one of the greatest threats to the marine environment to the marine ecosystem as they collect organic pollutants faster than inorganic particles, and marine animals accidentally ingest them. This problem is so acute that the United Nations (UN) is calling for actions to be taken.
It also mentions that Seabin technology captures all surrounding debris and also removes considerable amounts of microplastics 2mm and greater, preventing the particles from breaking down into smaller pieces in the water. 

The article states that the Seabin method is cheaper and more time-efficient compared to the standard method used. It is also being studied as an alternative scientific monitoring tool. The Seabin Project joins current global efforts to reduce microplastic and microfiber loads in the ocean. More research and development are carried out so that the Seabin will be able to remove even smaller particles of microplastics in the near future.

Intro Letter


Subject: Self-introduction

Dear Prof Blackstone,

My name is Muhammad Syafiq Bin Salleh and I am writing this email to give a brief introduction about my educational background and professional interest in engineering. I graduated from Temasek Polytechnic with a diploma in mechatronics engineering. Currently, I am pursuing my degree in mechanical engineering offered by the Singapore Institute of Technology and attending your effective communication class.

My strength in communication is that I enjoy socialising with new people. It helps to broaden my perspective of the world when we share our experiences so that I do not get caught up with only the things I already know. In a way, I will improve my general knowledge and at the same time have more topics to talk about when I meet another stranger. A weakness that I strongly agree with is that I have difficulties composing myself whenever I am doing public speaking. I will overthink the contents that I am about to share thus losing concentration and resulting in me stuttering throughout my speech as I try to recall the things I have to say. At times, I may over-explain myself and side-track from the focused topic.

One of the takebacks I wish to achieve from this module is the ability to give a good speech where my audiences get enlightened on the topic I am conveying. This is to not make them feel like they are being forced into listening to me. Another skill that I wish to gain is knowing how to expand conversations. Learning how to keep conversations rolling rather than leaving it hanging. More importantly, to overcome my weakness when it comes to presentations where I find it difficult for me to convey messages to my audiences.

I would like to thank you for taking the time to read this letter.

Sincerely,
Syafiq
