Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single aquatic exercise system is used, then the cost and complexity are reduced, but the ability to serve multiple swimmers simultaneously is limited
Solution Approach 1:
The system is divided into multiple independent exercise stations, each with its own resistance mechanism. Each station can be independently configured and adjusted, allowing multiple swimmers to exercise simultaneously while maintaining manageable complexity through modular design
Solution Approach 2:
The system provides universal functionality by enabling multiple swimmers to use the same exercise equipment simultaneously with different resistance settings. The modular stations can accommodate various exercise types and user preferences, making the system adaptable to diverse needs
2Adaptability or versatility
If fixed resistance is provided to all swimmers, then the system is simpler to operate, but individual exercise needs cannot be accommodated
Solution Approach 1:
The resistance mechanism is made dynamic and adjustable, allowing each swimmer to customize their resistance level according to their individual fitness level and exercise goals. The system transitions from static fixed resistance to dynamic adjustable resistance while maintaining ease of operation through intuitive controls
3Reliability
If expensive durable materials are used, then the system reliability and durability are improved, but the manufacturing cost increases
Solution Approach 1:
The system uses segmented modular components that can be manufactured separately using cost-effective materials and assembly methods. This segmentation allows for standardized production of durable parts while controlling overall manufacturing costs through economies of scale
Solution Approach 2:
The system optimizes material selection by changing parameters such as material thickness, density, and composition based on specific component requirements. This allows using lighter, less expensive materials where sufficient while maintaining durability through strategic material placement and structural design
