Day 11
03/10/2018
The team discussed on the value proposition canvas and narrowed down on what the products gains/pains/jobs are.
The team went through Day 10's results and brought it towards the value proposition canvas, where the input changed how the team did the canvas.
The team identified the problems of other existing products and want to solve them through the project.
Progress of the project can be seen on "2nd Design Process"

Day 12
Day 12
04/10/2018
The team went to meet up with the team's mentor for discussion of the project and overall direction
At there, the team gave updates to the mentor at greater detail and future plans.
There are 2 main models discussed: using compressed air and using a strap to pull the muscle groups. Further details will be updated in the "2nd Design Process", but a rough summary is that using these methods does not restrict the movement greatly, can be activated to move the muscle groups and can be done with a motor or a vacuum pump, all of which are feasible.
The progress was commented to be good and on pace despite having a week of rejection for other ideas. All in all, it's a more inactive day for the progress of the project.
Future plans will be uncovered for the next few posts.

Day 13
Day 13
08/10/2018
The team went to discuss on the cost and materials required for the final product. There were some limitations with finding the right pipe size, right pump and the air bags needed. Currently the team can only find air bags within 1000 a bulk as a minimum order, which is outside of the team's budget and in excess of the project.
The team also went to purchase quick prototyping tools for the next day so that the representation of the idea will be understood better.
The team also contacted experts and are planning to meet her on the following few days to understand the field of study even better.
Within the free time, the team did some diagrams and representation for the final product, so that the translation to the final product will be easier and have an end goal to be working towards.
A new page called "To the End Goal" is made for documentation of tasks and progress that relates towards the final product.

Day 14

After discovering the issues with purchasing equipment, the team proceeded to find alternatives to fulfill the requirements of the final product.
Alternatives ranges from creating a high pressure air bag to dismantling a massage chair to finding cheap air bags.
The team will try to discover more methods and use the most feasible method to achieve the end goal.

Day 15
10/10/2018
The team headed off to SUTD for the Business Model Canvas workshop. At there, the team learned about how to propagate the product to fit the users, what is there needed for the services and cost structure and how to outsource for parts.
The team will upload the online version of the Business Model Canvas for easier updates and viewing. The progress can be seen in "2nd Design Process".

Day 16
Day 16
11/10/2018
The team created the minimum viable prototype.
The team uploaded the BMC to the website.
The team came up with the interview questions to ask the experts
The team went to interview an expert to get feedback on the prototype. The biggest insight is that to solve hunchback issues, the current design of a tube from the lower back to below the shoulder blades will be sufficient. This does not solve scoliosis issues as scoliosis are caused by the rotation of the body.
The team will be focusing on the next day on redoing the design aspect.
All of the process of Day 16 will be uploaded to the "2nd Design Process" page.

Day 17
Day 17
12/10/2018
The team went to reevaluate the interview data collected from yesterday to understand the boundaries of the product and how to tackle newer issues.
Newer designs are catered towards scoliosis and hunchback issues, not entirely solving the problems but having a corrective method for the users.
With newer designs will have newer Bill of Material. The team will be planning to go shopping for the parts so that the team can carry out the initial prototype.
As of 12th of October, the team will be focusing their efforts on one design even if it is ineffective. This is to identify underlying problems that may not be obvious by the team and experts alike.

Day 18
Day 18
15/10/2018
The team discussed with the lecturer in charge of the direction of the project
The team went over the idea and how should it be implemented
The team went to acquire supplies for the prototype at NTUC and Clementi Town Square, products such as food sealers and latex gloves for material testing
Finalised the prototype concept at T1441.

Day 19
Day 19
16/10/2018
The team went to acquire supplies for the prototype.
Started the fabrication of our 2nd prototype.
Testing of materials.
There are some discoveries made while testing. The sealing is strong but the cut out for the air nozzle is not air tight and has a problem with ensuring high pressure in the air bags for correcting the posture.
The team will get a base model to work on the next day

Day 20
Day 20
19/10/2018
The team has continued on the prototyping and have encountered various problems within the project.
What was done was focused on creating air bags and sewing on pouches to fit the air bags inside the jacket.
The main problems are:
- Plastic material is too weak
- Requires tight fitting
- Pressure setting has to be high
- Even with high pressure and tightness, cannot feel the effects well
- Arrangement of air bags are important. Cannot be placed wrongly
The team decided to opt for a strap idea where the straps will pull the body and is determined based on the motor power. Compared to air bags, the straps only issue faced is more on it snapping (which can be controlled better than air bag bursting).
The team will be focusing on research of the straps and how to operate it better. The initial prototype to present has been done, but whether to make it more refined depends on the mentor's view of the project.
