Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wiring terminals and energizing terminals are used for color temperature adjustment, then the adjustment function is achieved, but the volume becomes large and structure becomes complex

Engineering Contradiction:

Improvecolor temperature adjustment functionVSAvoiddial switch volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent merges the wiring terminals and energizing terminals into a single integrated contact structure on the light source plate. The contact member integrates both functions into one component, eliminating the need for separate wiring terminals and energizing terminals, thus reducing volume and simplifying structure while maintaining the color temperature adjustment function.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The contact member serves multiple functions: it acts as both the wiring terminal and the energizing terminal, and also provides the sliding mechanism for adjustment. This multi-functional design reduces the number of components needed, thereby reducing overall volume and structural complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If wiring terminals and energizing terminals are used for color temperature adjustment, then the adjustment function is achieved, but the structure becomes complex requiring precise layout design

Engineering Contradiction:

Improvecolor temperature adjustment functionVSAvoidinternal structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into the contact member: it serves as both the wiring terminal and energizing terminal, and provides the sliding mechanism. This merging reduces the number of separate components and their interconnections, thereby simplifying the internal structure and reducing layout design complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the complex multi-component terminal structure and replaces it with a single integrated contact member. This extraction of the essential function from the complex structure simplifies the overall device architecture and reduces layout design requirements.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If wiring terminals and energizing terminals are used for color temperature adjustment, then the adjustment function is achieved, but assembly difficulty increases

Engineering Contradiction:

Improvecolor temperature adjustment functionVSAvoidassembly difficulty

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent merges the wiring terminals and energizing terminals into a single contact member that is directly formed on the light source plate. This eliminates the need for separate assembly steps to connect multiple terminal components, significantly simplifying the assembly process while maintaining the color temperature adjustment function.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The contact member is pre-formed on the light source plate during manufacturing, with the sliding mechanism and contact points already in place. This preliminary preparation of the contact structure eliminates the need for complex assembly operations, making the assembly process simpler and more efficient.

Inventive Principle:
