Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple power lines are provided for charging, driving power, and power balancing, then the wearable electronic device can perform all required functions, but the electrical resistance increases and device arrangement efficiency decreases
Solution Approach 1:
The patent combines multiple power lines (charging line, driving power line, and power balancing line) into a single integrated power line that performs all three functions. This merging approach reduces the number of separate conductors, thereby decreasing electrical resistance and improving device arrangement efficiency while maintaining complete power management functionality.
Solution Approach 2:
The single power line is designed to serve multiple purposes: it provides external power input, distributes driving power to devices, and enables power balancing between batteries. This multi-functional design eliminates the need for separate dedicated lines for each function, resolving the contradiction between functionality and complexity.
2Adaptability or versatility
If multiple power lines are provided for charging, driving power, and power balancing, then the wearable electronic device can perform all required functions, but the device arrangement efficiency is significantly reduced
Solution Approach 1:
By merging multiple power lines into one, the patent reduces the space required for routing and arranging devices within the wearable electronic device. This consolidation improves device arrangement efficiency while preserving all necessary power management functions through intelligent control of the single power line.
3Reliability
If the power lines are thickened to reduce resistance, then the electrical resistance decreases, but the efficiency of arrangement of the devices is significantly reduced
Solution Approach 1:
Instead of using multiple thick power lines to reduce resistance, the patent merges the functions of multiple lines into a single line. This approach achieves low resistance without requiring increased wire thickness, thereby maintaining efficient device arrangement while ensuring reliable power transmission.
