define a real need
development of specialized expertise & experience
establish industry partner realtionships
complete a user trial
development of multiple prototypes
valuable addition to my portfolio
business potential (market size)
entrepreneurial objective
I have a strong interest in finishing the year with a viable product or
service that could be the beginning of a business. From this single
product/service, a larger offering and an expanded business will be
developed.
If a strong grad project is developed but a business opportunity not
immediatly viable, then the focus will move to working with a smaller
start up as a designer - ideally an industry partner from the 4th year
project.

DESIGN BRIEF
DESIGN BRIEF
opportunity
fit & ergonomics
inflation system
- the vest must be snug on a range of users (there will be
multiple sizes)
- the vest should not “ride up” when worn in or out of the
water.
- maximize freeboard: distance from mouth to water
- easily detach and replace CO2 canisters
- once system inflated, easy to repack, rearm and reuse
Pre-Inflation
Water buoyancy aids are bulky and not suitable for many activities and
as such are often not worn at all. An opportunity exists to design a
better, performance based buoyancy vest.
- user has unencumbered swimming ability
- breathability: if one wears a vest containing a bladder it
could be like wearing a plastic bag. minimize this effect.
- stretch: the bladder material won’t stretch with the rest
of the vest and must be addressed.
- bulk: must not feel bulky or be restricting
users
Post Inflation
general swimming
- primarily submerged to neck
- full shoulder range of motion & torso movement
- bulk/size: the vest must not restrict movement
excessively
- ride up: need to keep flotation down and away from the
face and as tight to the body as possible
- flip onto back: the inflated life jacket will not have to flip
the user onto his/her back, because if they are unconscious
the lifejacket won’t be deployed anyway
surfing
- swimming underwater (duck dive)
- lay on front
- full shoulder rotation & torso movement
stand up paddleboarding
- primarily out of water
- additional features: carry water, storage
- breathability
- full shoulder & torso movement
Psychological Considerations
- provide piece of mind
- perception of safety issue: kiters ability to go out in
double overhead that most surfers would fear. the perception of safety is skewed and the strength of the wave and
water not understood.
- it’s about creating confidence
- help to provide solution to entrenched social attitudes:
complacency about risk and over confidence in swimming
ability, experience and judgement
kiteboarding
- design around waist harness
- able to continue to kite post inflation
- full shoulder rotation & torso movement
- equipment catch issues
Repacking
- the most difficult part is getting all of the air out as bladders are intricately folded and require close attention to
the instructions.
- cost of rearming kit
- speed and ease of repack
Arming System: Use an existing one, or design new one?
Need to visually show that the jacket is armed (e.g. green/
red)
Air Canister
- out of the way location
- durable
- small as possible
- flat?
- light weight
Inflation System Considerations
Air Canister
- compressed CO2
- known, affordable
- relatively small
- bladder can be reused
Self Inflate
- slow but reliable
- hard to do once in water
- reusable
windsurfing
- harness consideration
- full shoulder rotation & torso movement
Chemical Reaction
- likely fast
- “solid” buoyancy (no punctures)
- not reusable
coast guard / rescue
- jump from helicopter/boat
- full swimming capability
Inflatable Systems: Pros and Cons
existing alternatives
Pros
- high visibility when inflated
- turns most wearers face up when inflated
- may be more comfortable
- superior in-water performance

Cons
- multiple steps to deploy
- not suitable for non-swimmers
- not approved for under 16
- not appropriate for activities involving frequent water
entry or high speed
- require frequent inspection and maintenance

DESIGN BRIEF
regulations
user trials
USCG (United States Coast Guard)
- variety of body types & experience
- subjective: how safe they feel in the jacket & how cool they feel
- measurements: sense of security, wearability, in-water comfort,
length of inflation (hours)
“TYPE III life jacket”: when used beyond narrow limits of swimming,
surfing or bathing area you must carry:
- USCG approved life jacket
- sound signal device (whistle)
- visual distress signal & navigation light (flash light)
Transport Canada
Minimum safety equipment for sailboards and kiteboards:
- wear a PFD of appropriate size AND carry a sound signaling device and flashlight.
- for expected immersion in water
Approval Process
1. Standards are set by Canada General Standards Board and tested
via their lab as well as by Underwriters Laboratories of Canada (www.
ul.com/canada)
cost
- must not be prohibitively expensive
- similar products on the market range in price from $80-140
- suggested retail: $150-200
potential manufacturers
- Aropec Sports Corp (Taiwan) www.aropec.com
- Mustang Survival (Canada) www.mustangsurvival.com
2. After successful testing by ULC they are approved by Transport
Canada for use.
PFD’s are tested for:
- durability
- flammability
- ripstop
- flotation characteristics (angle & freeboard)
- strength of seams, buckles, zippers
- CO2 mechanism
PFD requirements (non-inflatable)
- 15 lbs of buoyancy
- snug
- designed for constant wear
- any colour
“Inflatable PFD” requirements
- 34 lbs of buoyancy
- must be 16 years of age
- not approved for whitewater paddling or personal watercraft
- must have oral inflation tube
- must have owners manual
Note: An average adult requires 7lbs of buoyancy to remain afloat
with his mouth clear of the water.
packaging, manuals
Idea: Supply two CO2 cartridges with purchase and ask the user to test
the vest when they purchase to ensure they know how it works.
Design requirements:
- complete instruction manual: care and maintenance
- rearming kit packaging
The ultimate PFD is one that you’re wearing when things go wrong.

USER PERSONA
USER PERSONA
TOM
Tom has been a waterman most of his life. He
grew up watersking, then wakeboarding and
soon discovered surfing. He grew up in Vermont
but moved to Oregon to pursue his love of the
ocean and mountains. Through his work as a
film producer and director of extreme sports
films he is afforded a fair amount of travel
throughout the world and always tacks on a
week or two at the end of each trip to kiteboard
or surf.
Tom and his friends like to push their comfort
zone in the water, searching for bigger waves,
windier locations all the while trying newer and
bigger tricks. For the most part he feels very
safe in the water but every once and a while he
gets “worked” by a wave or crash landing and
instantly feels vulnerable, remembering what
an unforgiving place the water can be. These
incidents are good reminders of how quickly
things can change in the water and a situation
can become dangerous in an instant.
Tom owns a modest home but doesn’t spend
much time there. He’s his own man, and moves
in a number of social circles both urban and
outdoorsy. Understated modesty with a wink
best describes his style. He’s reached his 30’s
now and isn’t necesarily looking to settle down
but his priorities are shifting as he looks for a
little more consistency in his life along with a
longer-term partner.
Tom wears a helmet when he skis and a
lifejacket when he wakeboards but opts out of
any safety equipment when kiteboarding or
surfing – arguably the more dangerous of all the
sports. He’d consider a buoyancy vest of some
sort if it fit like a glove and didn’t interfere with
his performance. He’s not so worried about any
ridicule as long as the vest looks legit and is in
fact somewhat bad-ass. It’s unlikely he’d wear it
in small waves but would have it in his car with
his wetsuit for the those big days when a little
back up may be necessary – you never know.

USER TRIAL TEAR SHEET - PAGE 2
FASTENING SYSTEM
BLADDER SHAPE
STYLE
From the user trials it was immediately evident
that the system to hold the sling down did not
work as designed. A fastening system that
compresses across the chest is required.
The user trial bladder worked well but
some adjustments to its shape over the
shoulder are required.
“Will they wear it?”
This question has becoming increasingly
prevalent now that the functional proof of
concept is complete. Aesthetics, positioning,
branding and a specific target group must be
addressed to elevate the artefact beyond being
simply a life vest and representing a badge of
respect.
NOTE: This updated design and colours
are for example only. Sling design and
colour palette’s to be explored.
