| Ergonomic Design | respects human psycho-physical limits
Example: staircase JumboStep - the weight of the product (not beyond 20 kg) - the stair dimension (for 2 feet at least) - the sequence of the stairs (distance 23 centimetres, without superimposition) - open stair sideways (not imprisoned by stiles) - the stability in the moment of the use (kick-stop) - self-instructing |
| Structural Design
|
takes account of the static and dynamic limits of the product
Example: CityStep - the duty rate of the step (140-150 kg) - the resistance to oxidation (aluminium, polyammide) - the operational reliability (automatic locking in different positions) - the shock resistance (rung-caps made of polyammide) - fast assembly (polyamid rivet integrated in the rung-cap) - easy in field replacement of parts (rung caps, hinge handle) |
| Functional Design | takes account of environmental and aesthetic marketing of the product
Example: staircase JumboStep - stylistic adaptation (different colours of the pads) - easy cleaning and maintenance (anodised aluminum, pads made of of polyetilene foam) Life cycle control and recycling: Example: the hinge of the staircase CityStep - easy disassembling of all plastic and steel parts |
