Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a capsule medical apparatus uses external power supply to reduce size, then the apparatus size is reduced, but the power reception capability is limited
Solution Approach 1:
The spiral coil structure serves dual functions: it acts as both a power receiving antenna and a sending antenna for wireless communication. This multi-functionality eliminates the need for separate components, thereby maintaining compact apparatus size while enhancing power reception capability through the same structural element.
Solution Approach 2:
The patent optimizes the spiral coil's geometric parameters (turns, diameter, winding density) to maximize electromagnetic induction efficiency. By adjusting these parameters, the coil achieves enhanced power reception capability while maintaining a compact form factor suitable for capsule apparatus.
2Power
If a capsule medical apparatus uses a spiral coil for power reception, then power generation efficiency is improved, but the device complexity increases
Solution Approach 1:
The spiral coil is integrated directly into the capsule apparatus structure, merging the power reception function with the existing device architecture. This integration approach improves power generation efficiency while avoiding the need for separate, complex power supply systems, thus managing device complexity.
Solution Approach 2:
The patent replaces traditional mechanical battery systems with an electromagnetic induction-based power reception system using the spiral coil. This substitution eliminates mechanical components and simplifies the overall device structure while achieving superior power generation efficiency through electromagnetic fields.
3Device complexity
If the same coil is used for both power receiving and sending, then device complexity is reduced, but the power reception capability is limited
Solution Approach 1:
The spiral coil is designed to perform both power reception and signal transmission functions simultaneously. By utilizing the same structural element for dual purposes, the patent reduces device complexity while maintaining adequate power reception capability through optimized coil geometry and electromagnetic induction principles.

Data Source
AI summary
A capsule casing is inserted into the living body, a thin-film substrate is cylindrically-shaped with approximately the same size of the inner surface of the casing and a coil for receiving an AC magnetic field is formed, and thus AC power is generated by the AC magnetic field from the outside of the living body with a small mounting space.
