Design for Manufacture #3

During the week the main body has been decided on and then vacuumed formed to create the shells shown on the right hand image.

The areas marked by tape show the positions that i wish to insert dividers.

Final Model Manufacture #2

Now I have the general shape of the final model.

I must continue on this path to ensure that the general shape reflects the aesthetic i wish to convey.

I must also think about the hinging mechanism i'm planning to utilise.

This is important as it will define the door mechanism.

Final Model Manufacture

The final model will be made from two plastic shells.

This will show it in a semi open condition.

Redesigning Strap Mechanism

Scan of revised FYP Design 004

This is the current design i am investigating  for the First Aid Deployment System.

Its based on the system i observed used in professional photographer bags.

It allows for the unit to swing freely when released.

Anaylsis of Current design

Although i'm generally happy with the design, after discussing the design with my lecturers several flaws have occured to me.
Eg.

• The possibility of the top panel hitting/getting caught when opening it.

• The awkwardsness of having the door extend to the second part.
• Can the closing mechanism be a more stable approach?
• Perhaps one sided only?
• What method will the door have of opening then?
• It was also brought to my attention that the contrast between the two pieces is very sharp and that maybe i should investigate a method of tieing the two together more.

So these are three aspects i should deal with immediately.

Progress Report

Over the past week I have Made the following decisions regarding my design.

• Have decided on using a hard plastic for the main body of my product.
• (Probably Polypropylene or polyethylene)
• I have to Change the location/shape of the quick access compartment for ease of use
  

• .I have decided on the general aesthetics of the final product(pictured below, but that is not the final shape/design)
  

Test 1

Things i am immediately working on are

• Methods of protecting thecontents during "heavy" use from the elements
• Attaching the padding and strap to the main body
  

Week 6 update

I'm currently investigating the following areas in my design:

• Looking at different locations/configurations for the easy access compartment located at the side of the product.

• Perhaps even having it as a detachable insert (Ease of replacement/cleaning)

• A New method of protecting the materials from the elements when exposed (Blister packs/ Hood idea??)

• And finally i have to make the decision whether to use hard or soft materials for the final product.
  

Dealing with Aesthetics

            Investigated a new aesthetic design, without trying to compromise the surface area against the back, or the volume it can carry.

I also need to explore methods of attaching the strap to the final unit.
