Variables
Strengths & Limitations
Strengths
- +Addresses a clear market need for affordable mobility enhancement.
- +Demonstrates successful iterative design and problem-solving.
Limitations
The prototype's weight and control were noted as areas for improvement, indicating potential trade-offs in the design.
Reliability & validity
The study's validity is supported by the successful achievement of most project goals with the second prototype. Reliability would depend on the consistency of performance across multiple trials and potentially with different users.
Think critically
To what extent does the 'affordability' goal of this hybrid design truly meet the needs of all potential users, and what are the ethical considerations of providing a 'lesser' but cheaper option?
Design Principles
"Modular design can extend product lifecycles and cater to a wider range of user needs and budgets."
This approach addresses a critical gap in the mobility device market by offering a cost-effective solution that bridges the functionality of manual and power wheelchairs. It allows for greater independence and accessibility for users who may find manual wheelchairs insufficient but full power wheelchairs prohibitively expensive or complex.
What This Means for Your Design
You can make a manual wheelchair better by adding a simple motor and battery pack, making it easier to go up hills and on bumpy ground without costing as much as a full power wheelchair.
