Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If recovered products are stored without special consideration on pallets with dividers, then storage simplicity is maintained, but product identification accuracy and reuse optimization deteriorate

Engineering Contradiction:
Improvestorage simplicityVSAvoidproduct identification accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

RFID tags serve as an intermediary identification mechanism between the recovered products and the management system. The tags are attached to products or their containers, allowing automatic identification and tracking without complex manual sorting or labeling processes, thus resolving the contradiction between simple storage and accurate identification

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces manual identification methods with automated RFID reading systems. Instead of requiring physical inspection or manual barcode scanning, the system uses electromagnetic fields to automatically detect and identify recovered products, improving identification accuracy while maintaining operational simplicity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If multiple types of rubber mixtures are used to optimize tyre properties, then product quality improves, but inventory complexity and management difficulty increase

Engineering Contradiction:
Improveproduct qualityVSAvoidinventory complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system segments the inventory management by creating dedicated storage spaces or zones for different types of recovered rubber mixtures. Each mixture type is isolated in its own segment, allowing optimized storage while the RFID system provides centralized tracking, thus managing complexity through structured organization

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the identification parameter from manual labels to RFID tags, enabling automatic differentiation between multiple mixture types. This parameter change allows the system to handle diverse product types with a single unified identification technology, reducing management complexity while maintaining product quality optimization

Inventive Principle:
Principle #35Parameter changes

3Productivity

If recovered products are identified and managed with RFID tags, then identification speed improves, but system complexity and implementation cost increase

Engineering Contradiction:
Improveidentification speedVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The RFID tags serve multiple functions simultaneously: identification, tracking, inventory management, and product differentiation. By making the identification system multi-functional, the patent reduces the need for separate complex systems for each function, thereby limiting the increase in overall system complexity while achieving high identification speed

Inventive Principle:
Principle #6Universality (Multi-functionality)
