Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional robots use battery power, then they can operate autonomously, but the battery configuration increases device volume and moving resistance, limiting miniaturization
Solution Approach 1:
The patent removes the battery from the robotic device entirely, extracting the power storage function from the device volume. The wireless power transmission system provides energy externally through electromagnetic fields, allowing the device to maintain autonomous operation without carrying heavy battery packs, thus achieving miniaturization while eliminating moving resistance caused by battery configuration.
2Volume of moving object
If robot size is reduced for narrow environment operation, then it can access confined spaces, but battery-free operation becomes challenging with limited power availability
Solution Approach 1:
The patent introduces electromagnetic fields as an intermediary energy transmission medium between the external power source and the miniaturized robotic device. The wireless power transmission system uses electromagnetic coupling to transfer energy across the water-medium interface, enabling continuous operation of small-scale robots in narrow aquatic environments without compromising power reliability or operation continuity.
3Adaptability or versatility
If conventional robots operate in aquatic environments, then they can perform monitoring tasks, but they struggle in narrow confined spaces due to size constraints
Solution Approach 1:
The patent designs a universal wireless power reception system that can be integrated into robotic devices of various sizes, enabling both large-scale and miniaturized robots to operate autonomously in diverse aquatic environments. The same electromagnetic coupling mechanism works across different scale regimes, allowing the technology to adapt from broad open-water monitoring to narrow confined-space exploration without requiring fundamentally different power solutions.
