Problem Description

• We are in the R&D (Research and Development) of wheelchair. Our role is to predict the future of wheelchair and to develop new ideas; which will help generate more revenue and gain new market share.

PART 2

2.1 Problem Statement

• What is the future of wheelchair? Develop new ideas for wheelchair.

2.2 Benefits or impacts if problem is solved

• We can generate more revenue and gain new market share.

2.4 S-CURVE ANALYSIS

2.4.1 Main Parameters of Value (MPVs)

• MPVs reflect what matters to customers, hence they are the best compass by which to guide innovation efforts. We must identify the MPVs for wheelchair.

2.4.2 Current MPVs of Wheelchair

• Mobility

• Comfort

• Accessibility

2.4.3 S-CURVE STAGE OF WHEELCHAIR.

2.4.4 INDICATORS FOR SECOND STAGE

• The Engineering System moves into mass production.

• The Engineering System adapted for use in different applications.

• The Engineering System become more widely differentiated.

• Supersystem elements begin to adapt to the Engineering System.

2.4.5 RECOMMENDATIONS FOR SECOND STAGE

Adapt the Engineering System to new application.

Diving Type Wheelchair.

2.5 TREND OF ENGINEERING SYSTEM EVOLUTION (TESE)

Engineering System do not develop randomly, in fact, they develop according to objective Evolutionary Trends. Thus, we can predict the future of an Engineering System based on the Trend of Engineering System Evolution (TESE). In our wheelchair case, we choose 2 of them to predict the future of wheelchair, which are Trend of Elimination of Human Involvement and Trend of Increasing Dynamicity.

2.5.1 TREND OF ELIMINATION OF HUMAN INVOLVEMENT• Is a sub-trend for Trend of Increasing Completeness of

System Components. • As an Engineering System evolves, the number of Engineering

System functions performed by human decrease.

• Wheelchair needs to be propelled by the user or with the aid of another person.

• Electric-motor is used to move the wheelchair. In future, wheelchair should be fully controlled by human brainwave.

2.5.2 TREND OF INCREASING DYNAMICITY

As an Engineering System evolves, it and its components become more “dynamic”. The Trend of Increasing Dynamicity is illustrated in

In the past, wheelchair is solid and not foldable, at is considered in monolith state. In present, the parts of wheelchair can be adjusted and wheelchair is foldable for easy to store, it is considered combining multi-joint and elastic state. In future, we predict that wheelchair can combine multi-joint, elastic and gas state. That means the cushion of wheelchair is inflatable, which make wheelchair more comfortable to sit on and also can be fold after being use.
