Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If EM probes are designed to monitor biological tissues, then measurement capability is improved, but sensitivity to external noise and interference increases

Engineering Contradiction:

Improvetissue monitoring accuracyVSAvoidexternal noise sensitivity

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies absorbing material to the exterior surface of the probe to convert harmful external electromagnetic noise into beneficial signal isolation. The absorbing material captures external EM radiation and converts it to heat, preventing it from interfering with the sensitive measurements being taken by the probe, thus transforming the harmful interference into a useful isolation mechanism.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The absorbing material acts as an intermediary layer between the external electromagnetic environment and the probe's sensitive measurement components. This intermediate layer filters and absorbs unwanted EM radiation before it can reach the probe's sensing elements, allowing accurate tissue monitoring while blocking external noise and interference.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If absorbing material is applied to the probe exterior, then signal isolation is improved, but device complexity increases

Engineering Contradiction:

Improvesignal isolationVSAvoidprobe structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs thin film absorbing material applied to the probe's exterior surface rather than bulky shielding structures. This thin film approach provides effective signal isolation and noise reduction while maintaining a compact, simple probe design that does not significantly increase device complexity or size.

Inventive Principle:

Principle #30Flexible shells and thin films
