Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If tissue assessment is performed directly at the treatment site, then measurement accuracy is improved, but device complexity and space requirements increase

Engineering Contradiction:

Improvetissue assessment accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary computational model (transfer matrix) that maps measurements from accessible locations to target treatment sites. This mediator enables indirect assessment without requiring complex sensors at the treatment location, resolving the contradiction between measurement accuracy and device complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates a virtual copy or model of the treatment site conditions by computing transferred measurements from accessible locations. This computational copying allows accurate tissue assessment without physically placing measurement devices at the difficult-to-reach treatment site, reducing device complexity while maintaining measurement precision.

Inventive Principle:

Principle #26Copying

2Reliability

If multiple measurement locations are used, then information reliability is improved, but device complexity increases

Engineering Contradiction:

Improveinformation reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The transfer matrix serves as a universal computational tool that can process measurements from multiple different locations and translate them to target site information. This single multi-functional approach replaces the need for separate complex measurement systems at each location, improving reliability while controlling device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Measurement precision

If direct measurement at treatment site is performed, then information specificity is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveinformation specificityVSAvoidprocedure simplicity

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

Instead of placing sensors directly at the treatment site (direct measurement), the system inverts the approach by placing sensors at accessible locations and computationally transferring the information to the target site. This inversion maintains information specificity while dramatically improving ease of operation.

Inventive Principle:

Principle #13The other way round (Inversion)
