VSEngineering Contradiction Analysis

1Ease of operation

If radio signal transmission is used for wireless image signal transmission from capsule-type endoscope, then ease of operation and patient comfort are improved, but electromagnetic interference occurs causing image quality degradation and diagnostic accuracy reduction

Engineering Contradiction:

Improvewireless operationVSAvoidelectromagnetic interference

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The receiving device counts synchronization signals in received image signals and generates determination information indicating whether interference has occurred. This feedback mechanism allows the system to detect interference levels and potentially alert users or adjust transmission parameters to maintain image quality while using wireless communication

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Synchronization signals serve as an intermediary element embedded within the image signal. By counting these specific synchronization signals, the system can determine interference levels without affecting the primary image transmission function, thus mediating between wireless communication benefits and interference problems

Inventive Principle:

Principle #24Intermediary (Mediator)
