Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If multiple batteries are connected individually to an electric drive, then the range of the electric bicycle is increased, but the number of cables and cable breakouts increases, resulting in increased manufacturing costs and complexity
Solution Approach 1:
Multiple battery connections are merged into a single integrated cable harness that routes all electrical connections through one consolidated pathway, eliminating the need for multiple separate cable breakouts and reducing overall system complexity
Solution Approach 2:
A universal connector design is implemented that can accommodate multiple batteries through a standardized interface, allowing the same cable assembly to serve multiple battery configurations without requiring variant-specific cable routing
2Use of energy by moving object
If several batteries are used to increase range, then the electrical capacity is improved, but the manufacturing costs increase due to multiple variants
Solution Approach 1:
A universal connector design is implemented that can accommodate multiple batteries through a standardized interface, allowing the same cable assembly to serve multiple battery configurations without requiring variant-specific cable routing
Solution Approach 2:
The electrical connection system is segmented into modular components where the cable harness is divided into interchangeable sections that can be configured for different battery arrangements, simplifying manufacturing while maintaining flexibility
3Adaptability or versatility
If multiple cables are routed externally to the frame, then connection flexibility is improved, but reliability and tightness risks increase due to exposure to external factors
Solution Approach 1:
Multiple individual cables are nested within a single protective outer sheath or cable harness, shielding them from external environmental factors while maintaining their individual electrical functions and connection flexibility

Function Achieved in This Case
This solution enables efficient and cost-effective production of electric bicycles with varying electrical ranges by simplifying battery connections, enhancing cable management, and improving battery management strategies, reducing manufacturing costs and enhancing safety.
Implementation Method 1
the electrical connection arrangement has at least one electrical resistance component. In this way, a resistance measurement can be carried out in a line, so that when several rechargeable batteries are present, a number of rechargeable batteries can be inferred and, more preferably, the type of rechargeable batteries can also be inferred.
