3 WEEKS OF GROUP RESEARCH

7 WEEKS OF INDIVIDUAL PRODUCT RESEARCH & DEVELOPMENT 

Initial Research
As a group we began the project by becoming experts on nearly everything to do with a fire extinguisher before we branched off into our individual focuses. 

I was responsible for: 

  • Graphic design of picto-gram icons

  • Extinguisher Styles (pg.7)

  • Manufacturing (pg.8)

20,000 RECREATIONAL VEHICLE FIRES OCCUR EACH YEAR IN NORTH AMERICA.

FOR EVERY 1000 FIRES = 4 LIVES ARE LOST AND 16 ARE INJURED.

ON AVERAGE $16,140/RV FIRE IS LOST IN DAMAGES.

Not exactly clear where to start when un-clipping

Locking mechanism requires excessive strength to un-clip

Existing Areas of Concern

After researching Recreational Vehicle (RV) fires, I visited an RV showroom where I interviewed an employee about:
  • User profiles
    • majority are retired couples and young families
  • What is required to drive/rent an RV?
    • Class G license, no required experience necessary 
  • Fire safety protocol
    • Each RV is required to have a fire extinguisher at each exit

Opportunity

Based off secondary research it was determined that current fire extinguishers were not ideal for RV's and their users. Improving ease of use, storage methods, intuitiveness and creating an allowance for manipulation would provide RV users with a more effective fire extinguisher in the case of a fire.

Playing around with different heights and diameters allowed me to keep the same volume while exploring different proportions.

Putting it to the Test

To accurately simulate each handling concept, each prototype was cut to similar dimensions of a fire extinguisher and filled with wet sand to give it a weight of 15lbs. 

Prototypes 

These works-like models were created to determine how manipulating a heavy fire extinguisher could be made easier or how users prefer to handle it.

Fire Simulation

Each participant was read a quick narrative of the situation at hand. The test required the participant to sweep from side to side in order to put out the"fire".

Design Intent

From the simulation I had come to the conclusion that in an emergency situation a user would manipulate the extinguisher to their own comfort. From there I began to develop new concepts and prototypes that brought to life a more literal interpretation of feedback given from the participants to test further.

This concept was not meant to be aesthetically pleasing, but rather created to bring together everything I wanted to accomplish. From there I would hopefully have a better understanding of what was required. There were 4 things I wanted to accomplish through the design...

Bringing it to life

Using a LDPE foam I modelled the general shape and size. This allowed me to discover that by flipping the handle over from where I originally thought, resulted in a more comfortable position.

MAnufacturing

To manufacture a looks like model, I created a 3D model using Solidworks which I then used to CNC a block of HDPE foam. The remainder of the model was carved by hand using rasps, files, a dremel and sand paper.
