Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If decentralized recycling processes are used, then flexibility and local adaptability are improved, but process reliability and coordination efficiency deteriorate

Engineering Contradiction:
Improvelocal adaptabilityVSAvoidprocess reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a centralized platform that acts as an intermediary between decentralized recycling facilities. This platform coordinates material flows, matches supply with demand, and ensures process reliability through centralized control while allowing local facilities to maintain their operational flexibility and adaptability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If physical sorting and packaging of materials are performed, then recycling process completeness is improved, but physical complexity and operational difficulty increase

Engineering Contradiction:
Improverecycling process completenessVSAvoidphysical complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent creates digital replicas (digital twins) of physical materials and their properties. Instead of physically sorting and packaging all materials, the system uses digital models to represent material configurations, enabling virtual sorting and matching processes that reduce physical handling complexity while maintaining complete tracking and processing capability.

Inventive Principle:
Principle #26Copying

3Measurement precision

If comprehensive material configuration data is collected, then material identification accuracy is improved, but data management complexity and processing time increase

Engineering Contradiction:
Improvematerial identification accuracyVSAvoiddata processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-collecting and structuring material configuration data at the source (during product design and manufacturing). Material passports and digital twins are created beforehand, containing all necessary information about material composition and properties. This pre-prepared data is then easily queryable during recycling, maintaining high identification accuracy without time-consuming data collection at the recycling stage.

Inventive Principle:
Principle #10Preliminary action
