Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the lamp holder rotates with fixed lighting elements, then the lighting elements remain stationary, but the wires connecting to the lighting elements will tangle during rotation

Engineering Contradiction:
Improverotation smoothnessVSAvoidwire tangling
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies the dynamics principle by making the lighting elements rotate synchronously with the lamp holder instead of remaining fixed. The lighting elements are mounted on the rotating lamp holder structure, allowing them to move dynamically with the rotation while maintaining their relative positions, thus preventing wire tangling during operation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the electrical connection system into multiple components: the first PCB remains fixed to the lamp holder body, the second PCB is attached to the rotating lighting elements, and flexible wires connect these two PCBs. This segmentation allows the rotating parts to move independently without causing wire tangling

Inventive Principle:
Principle #1Segmentation

2Device complexity

If the lighting elements remain fixed while the lamp holder rotates, then the structure is simpler, but the visual effect becomes static and less spectacular

Engineering Contradiction:
Improvestructure simplicityVSAvoidvisual effect
Core Design Contradiction:
Device complexityVSIllumination intensity

Solution Approach 1:

The patent transforms the static visual effect into a dynamic one by enabling the lighting elements to rotate synchronously with the lamp holder. This creates moving light patterns and enhances the visual spectacle while maintaining relatively simple structural design through the synchronous rotation mechanism

Inventive Principle:
Principle #15Dynamics

3Reliability

If the lighting elements rotate synchronously with the lamp holder, then wire tangling is prevented, but the electrical connection system becomes more complex

Engineering Contradiction:
Improvewire tangling preventionVSAvoidelectrical connection system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The electrical connection system is segmented into three main parts: a first PCB fixed to the lamp holder body, a second PCB attached to the rotating lighting elements, and flexible wires connecting these two PCBs. This segmentation allows the rotating parts to move independently while maintaining reliable electrical connections without wire tangling

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces flexible wires as an intermediary element between the fixed first PCB and the rotating second PCB. These flexible wires can accommodate the rotational movement while maintaining continuous electrical connection, thus preventing wire tangling and ensuring reliable power supply to the rotating lighting elements

Inventive Principle:
Principle #24Intermediary (Mediator)
