Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional visual inspection methods are used to verify pharmaceutical pouches, then the system remains simple, but verification accuracy and error detection capability are insufficient

Engineering Contradiction:
Improveverification accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple imaging modalities (visible light imaging, infrared imaging, and heated imaging) into a single verification system. The electronic processor integrates these different image types to comprehensively verify pharmaceutical pouch contents, resolving the contradiction by merging multiple detection methods to achieve high verification accuracy while managing system complexity through unified processing.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a heat source as an intermediary element that enables thermal imaging capability. By heating the pouch and capturing infrared images, the system can detect pharmaceutical contents through thermal signatures. This intermediary approach enhances verification accuracy without requiring direct contact with the pharmaceuticals, thus improving measurement precision while maintaining acceptable device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If multiple imaging modes are used to verify pouch contents, then verification reliability improves, but the time required for verification increases

Engineering Contradiction:
Improveverification reliabilityVSAvoidverification time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent employs periodic action by sequentially capturing visible light images, infrared images, and heated images in a structured sequence. The electronic processor coordinates these periodic imaging operations to verify pouch contents through multiple modalities. This periodic approach ensures comprehensive verification reliability while managing verification time through efficient sequencing of imaging operations.

Inventive Principle:
