The Design Brief How can design improve the safety of hair straighteners?
Hair straighteners According to Children Burn Trust, a hair straightener is one of top ten common reasons for children's burn admissions in the UK. Touching heating plates, and pulling the cable caused the burn injuries. The reason why children would have the chance to touch hair straighteners are that users did not keep them well, or not being aware of the fact that hair straightener stays hot after switching off 20 minutes or forgetting to turn off the hair straightener.
is one of the top child burn list.
Touching things was the most common cause of burns
67% of all contact burns affected hands.
The Inspiration The reason why chose the pilers to develop is that it seems the best way to avoid the heating plates always open. They naturally close together every time release the hair straightener. Besides, this design could clearly define the handles which can prevent from touching the hot area on the hair straightener.

Materials and Manufacture Titanium Panels ○ Lightweight ○ Fasten the heat-up ○ The longest longevity from all the heating panel materials
PPS Injection Mould ○ It would be applied for the parts that close to heating panels ○ Excellent heat-resistance
PET Injection Mould ○ Mainly used for the parts that do not require heat resistance heavily ○ Lower costs
The Matt White Surfaces ○ Pale tone to reduce the attraction to children ○ Aviod shiny finishes
Skidproof Rubber Handles ○ Increase the friction on the surface
It innovates a solution to reduce the risks of getting burn injuries. The X-shaped design gives the opportunity for the safety lock to sit in the centre which to reminds users to lock every time after use, and also keep users away from the heating panels.
Thank you. Any questions?
