Innovation Solution

A dial sheet-based dimming lamp with a simplified structure that includes a housing, light source assembly, and adjustment assembly, where a dial member drives a contact member to slide between connecting contacts on a light source plate, using an elastic sheet as the contact member to facilitate electrical conductivity and reduce overall volume.

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 increases 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, eliminating the need for separate wiring terminals and energizing terminals, thereby reducing volume and structural complexity while maintaining the color temperature adjustment function.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The contact member is designed to serve multiple functions: it acts as both the wiring terminal and the energizing terminal, and simultaneously provides the switching function for color temperature adjustment. This multi-functionality reduces the number of components needed and simplifies the overall structure.

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 functional elements into a single contact member structure. The contact member integrates the wiring terminal, energizing terminal, and switching mechanism into one component, significantly reducing internal structure complexity and eliminating the need for precise layout design of multiple separate terminals.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The contact member is segmented into functional zones (contact area, sliding area, connection area) that are clearly defined but integrated within a single component, simplifying the overall structure while maintaining functional separation.

Inventive Principle:

Principle #1Segmentation

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 convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By merging the wiring terminals and energizing terminals into a single contact member that is integrated with the light source plate, the patent reduces the number of assembly steps. The contact member is pre-assembled with the light source plate, eliminating the need for separate assembly of multiple terminal components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The contact member is pre-configured with the appropriate contact patterns and connections before final assembly. The sliding mechanism and contact areas are pre-positioned on the light source plate, allowing for quicker and easier final assembly without requiring complex alignment procedures.

Inventive Principle:

Principle #10Preliminary action
