What do you do?
Upmarket fashionable lady's shoes with a telescopic, height-adjustable heel: from low for easy walking, to high for impressing at the office (2 heights only).
What is the product designed to do?
Telescopic heel that can adjust with the slide of a lever at the top of the heel, so the wearer doesn't have to take their shoes off or get their hands dirty to change height. NB we have a design that just needs refining and perfecting.
List the size and weight requirement(s) for your product design
Heel in high position: 8.5cm including heel tip
Heel in low position: as low as possible: can we get it to 4.5 or 5cm including heel tip?
'Cup' that heel sits in approx. 5.5 to 6cm diameter
List all other important design requirements
The switch to change height must lock for safety reasons.
The internal pin will be made of hardened brass or steel (but will need the files so we can grow 3D samples for testing)
The current design is just the heel mechanism. It needs a 'cup' that will hold the heel mechanism , ready to be attached to the shoe. The surface of the cup must allow for 4x 10mm screws to be screwed in, so we will need a metal surface recessed in this cup to accommodate this (as photo provided, for example). A 'last' profile is provided to get the surface area correct. The 'cup' will have a slot for the lever that changes the heel height to protrude. Once the cup is designed, the total heel height, measured at the very back of the heel, must be as specified.

What 3 things would you like to communicate to your audience through your product design?

What products will this new product compete with?
Tanya Heath - removable heels. Issues with this: have to take shoe off to remove heel (can't do it on-the-fly); hands get dirty; what to do with the dirty heel once you've removed it? www.tanyaheath.com
Camileon Heels - out of business. Design was unattractive; had to clasp dirty heel to change height; design flaw in that the walking surface in the low position formed a crucial part of the heel stability in the high position, and this part gets worn with use.
What is your target retail price?
$150 / GBP95 per pair.
Style, Concept and Environmental Factors
What product design styles do you like?
Not a stiletto heel, but as slim a heel as possible. If we can reduce the thickness of the walls in the current heel design without compromising on strength, that would be great.
The unit must look stylish and the telescopic pieces must blend into one another as much as possible.
I am open to an oval heel design - doesn't have to be round, as long as it looks elegant.
What colors do you want to see in your product design?
What colors do you NOT want to see in your product design?
What adjectives should best describe your product design?
sleek, elegant, easy-to-use, stylish
Describe the operating environment for the product.
City pavements; all weather conditions in the US, Europe and the UK.
Do you have additional info or links you'd like to share?
Some background: shoemaking is still a very manual, labor-intensive process. Once the uppers are made, the heel is attached as a unit - either glued on, or screwed on. Because of the weight of our telescopic heel, we will need to have it screwed on. So we are trying to create a unit that the shoemakers can use as per their current process. See video to get an idea: https://www.youtube.com/watch?v=bmIrQTQl... - heel attachment from 2:48. Some terminology: the plastic foot-shaped thing they build the shoe around is called a LAST.
The tip on the end of the heel is called the top piece but I have also called it the heel tip.
