Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the diagnostic device is connected directly to each electric device with a wire, then accurate diagnosis can be achieved, but the diagnostic time increases significantly
Solution Approach 1:
The patent introduces a communication bus as an intermediary medium that connects all electric devices in the bicycle electrical system. The diagnostic device communicates with multiple electric devices through this single bus connection, eliminating the need for direct wired connections to each device while maintaining diagnostic accuracy. This resolves the contradiction by using the communication bus as a mediator that enables efficient multi-device diagnosis.
Solution Approach 2:
The communication bus serves multiple functions: it acts as both a power transmission line and a communication channel for diagnostic data. By making the diagnostic device able to communicate with multiple electric devices through a single universal interface, the system achieves accurate diagnosis of all devices without requiring separate connections, thus reducing diagnostic time while maintaining accuracy.
2Adaptability or versatility
If separate wires are connected to each electric device for diagnosis, then complete system coverage is achieved, but the operational complexity increases
Solution Approach 1:
The patent merges the connection to multiple electric devices into a single connection point on the communication bus. Instead of requiring separate wire connections to each device, the diagnostic device connects to the bus once and can access all electric devices through this single merged connection, significantly reducing operational complexity while maintaining complete system coverage.
Solution Approach 2:
The communication bus provides a universal interface that allows the diagnostic device to access all electric devices in the system through a single connection. This universal access mechanism eliminates the need for multiple separate connections, making the diagnostic process easier to operate while ensuring complete coverage of all devices.
3Adaptability or versatility
If multiple connection points are provided for different electric devices, then diagnostic flexibility is improved, but the device complexity increases
Solution Approach 1:
The communication bus acts as an intermediary network that provides diagnostic flexibility without increasing physical connection complexity. The bus architecture allows the diagnostic device to flexibly access any electric device in the system through a single connection point, maintaining adaptability while simplifying the overall connection structure.
