PRODUCT DESIGN AND DEVELOPMENT
(DESIGN OF HELMET)

ABSTRACT

In today’s automobile scenario two wheelers are at high rate of sales. The road accidents are happening frequently everywhere. This makes every person to wear a helmet to avoid head injuries. But due to the difficulties like sweating, hair fall every person hesitates to wear helmet even though rules are put by the government.

In this paper we develop most sophisticated design of helmet. The head size and profile of every person is different. The standard size available does not fit perfectly for many people. So we make CF linear which perfectly assemble into the helmet. This can be made for individuals separately and it also consists of small holes which increases air circulation and reduce the weight of the helmet and makes comfortable for the rider.

PRODUCT DESIGN AND DEVELOPMENT
(DESIGN OF HELMET)

DEFINITION:
The process of developing a product from initial stage of Design to Physical Reality using concept of Designing, manufacturing processes and other economical aspects OBJECTIVES:
The objectives of product development are as follows….. 1. Converting Design into Physical Reality
2. Design optimization of the product
3. Manufacturing optimization of the products
4. Economically applying on product to optimize it 5. Market the product

MOTORBIKE HELMETS - CF DEMO CASE

THE CONSIDERABLE VALUE OF A CUSTOMISED HELMET:
The helmet will be more comfortable
➢ The helmet is more bearable and so riders will be less inclined to go without one. The helmet will give better protection:
➢ Less risk to be pulled off
➢ Crash forces are more evenly across the skull
From production:
➢ Customizing the helmets make them higher value and easier to sell. ➢ It increases the sense of ownership and pride in that product which increases brand loyalty. ➢ It also ensures that the customer makes a commitment to the product before a helmet is fabricated. HELMET COMPOSED OF:

➢ outer shell which is manufactured from either thermoplastic or fibre reinforced plastic composite – inner liner formed from expanded polystyrene (EPS) ➢ a comfort padding which is soft and low-density Foam [pic]

PART BEING CUSTOMISED
The original idea was to customize Inner EPS liner BUT we cannot use EPS in RM So… A new CF liner was inserted between EPS and padding
– Safety still guaranteed by EPS and outer shell – Custom part is smaller (faster/cheaper to be manufacture via RM)

CUSTOM-FITTING HELMET
• 5% of motorcyclists cannot find helmets that fit their head geometry • 15-20% of all full face composite helmets are ill fitting • Helmet designed to absorb and disperse impact during an accident – The outer shell stops instantly.

– Inside, your head keeps going until it collides with the EPS. – EPS's job is to bring the head to a gentle stop (if you want your brain to keep working like it does now.
CHALLENGE:
Legal limitations on the volume that we can change within Custom-Fit and stay within the standard’s parameters CF LINER:
A new part between existing padding (comfort) and EPS* (safety).

PROCEDURE CUSTOM-FITTING HELMET
DATA FROM RIDERS:
• Scan of the rider (position of head!)
• Trim & repair,
• Align & landmarks
• Export geometrical and non-geometrical data...
