Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If large-scale processing apparatuses are used to form fine uneven patterns on object surfaces, then manufacturing precision is improved, but device complexity increases

Engineering Contradiction:
Improvefine uneven pattern formationVSAvoidprocessing apparatus scale
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical processing apparatuses with a simple inkjet printing system. Instead of using large-scale mechanical processing to create uneven patterns, the invention uses inkjet printers to deposit ink that dries to form natural uneven patterns. This substitution of mechanical systems with a simpler printing system resolves the contradiction by achieving fine pattern formation without complex equipment.

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

Solution Approach 2:

The invention utilizes the self-drying process of ink to naturally form uneven patterns on the object surface. The ink applied by the inkjet printer dries spontaneously, creating unique uneven patterns without requiring additional processing apparatuses. This self-service approach allows the system to generate the required fine uneven patterns using only the inherent properties of the ink material, eliminating the need for complex processing equipment.

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If conventional processing methods are used to form uneven patterns, then manufacturing precision is improved, but ease of manufacture deteriorates

Engineering Contradiction:
Improveuneven pattern formationVSAvoidprocessing simplicity
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent replaces conventional mechanical processing methods with inkjet printing technology. The inkjet printer can be easily positioned and operated to apply ink to objects, and the natural drying process creates the uneven patterns. This substitution makes the manufacturing process much simpler and more accessible while maintaining the ability to form fine uneven patterns for authentication purposes.

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

Solution Approach 2:

The invention introduces ink as an intermediary material that bridges the gap between simple application and complex pattern formation. The ink serves as a mediator that, when applied and dried, naturally creates the required uneven patterns. This intermediary approach allows the system to achieve fine pattern formation through a simple two-step process of ink application and drying, without requiring complex processing equipment or methods.

Inventive Principle:
Principle #24Intermediary (Mediator)
