Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a rigid elastic member is used in the adjusting mechanism, then the structural strength is improved, but the device complexity increases and manufacturing cost increases

Engineering Contradiction:

Improvestructural strengthVSAvoiddevice complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent removes the rigid elastic member from the adjusting mechanism, extracting the problematic component that caused complexity while maintaining structural integrity through alternative design approaches using the bracket and adjusting element

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the expensive rigid elastic member with a simpler, more cost-effective adjusting mechanism consisting of a bracket and adjusting element, reducing manufacturing costs while achieving the same functional outcome

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Manufacturing precision

If multiple assistant objects are used for alignment, then the alignment precision is improved, but the device complexity increases

Engineering Contradiction:

Improvealignment precisionVSAvoiddevice complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines the alignment function and support function into a single integrated bracket structure, eliminating the need for separate assistant objects while maintaining alignment precision through the bracket's geometric design and the adjusting element's positioning capability

Inventive Principle:

Principle #5Merging (Combining)

3Manufacturing precision

If a complex adjusting mechanism is used, then the alignment precision is improved, but the ease of manufacture deteriorates

Engineering Contradiction:

Improvealignment precisionVSAvoidease of manufacture

Core Design Contradiction:
