Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the light emitting assembly and ring surface are designed to rotate independently, then each component can be optimized separately for its function, but the rotation differentials cause negative user experiences and inconvenience
Solution Approach 1:
The patent merges the rotation control of the light emitting assembly and ring surface by connecting them through a common rotating frame. This ensures both components rotate synchronously, eliminating the rotation differential issue while maintaining the ability to optimize each component's design independently for its specific function.
2Adaptability or versatility
If the light emitting assembly rotates independently from the ring surface, then the lighting direction can be adjusted more flexibly, but it creates eccentricity that degrades optical quality
Solution Approach 1:
By merging the rotation mechanisms through a common rotating frame, the patent ensures that the light emitting assembly and ring surface maintain consistent relative positions during rotation. This preserves optical quality while still allowing flexible lighting direction adjustment through controlled rotation of the entire assembly.
Solution Approach 2:
The patent implements a dynamic rotation control system where the rotating frame enables coordinated movement of both the light emitting assembly and ring surface. This dynamic synchronization allows the system to adapt lighting directions while maintaining the precise relative positioning needed for optical quality.
3Adaptability or versatility
If separate rotation mechanisms are used for the light emitting assembly and ring surface, then each component's rotation can be controlled independently, but it increases device complexity
Solution Approach 1:
The patent combines the rotation control functions into a single rotating frame mechanism that simultaneously controls both the light emitting assembly and ring surface. This reduces device complexity by eliminating the need for separate rotation mechanisms while still providing coordinated control capability.
