Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate devices for wireless charging and radio wave measurement are equipped on aerial vehicles, then both functions can be performed, but the weight increases and operating time decreases
Solution Approach 1:
The patent combines wireless charging and radio wave measurement functions into a single antenna device. The antenna includes a first coil for wireless charging and a second coil for radio wave measurement, integrating multiple functions into one structure to reduce weight while maintaining both capabilities
Solution Approach 2:
The antenna is designed as a multi-functional device that can perform both wireless charging and radio wave measurement. The controller selectively activates different coils based on the required function, making the single antenna structure universal for both purposes
2Adaptability or versatility
If separate devices for wireless charging and radio wave measurement are equipped on aerial vehicles, then both functions can be performed, but the device complexity increases
Solution Approach 1:
The patent merges wireless charging and radio wave measurement into a single antenna structure with multiple coils. This integration reduces the number of separate devices and simplifies the overall system architecture while maintaining both functional capabilities
Solution Approach 2:
The single antenna structure serves multiple purposes through selective activation of different coils. The controller manages the antenna to perform either wireless charging or radio wave measurement, reducing system complexity compared to having separate dedicated devices
3Adaptability or versatility
If separate devices for wireless charging and radio wave measurement are equipped on aerial vehicles, then both functions can be performed, but the operating time decreases
Solution Approach 1:
The patent combines wireless charging and radio wave measurement functions into one antenna device, reducing the total weight of equipment on the aerial vehicle. This weight reduction extends the operating time while maintaining both functional capabilities through selective coil activation
