Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional light source unit is used in a saddle riding vehicle, then the lighting function is achieved, but the vehicle's traveling performance deteriorates due to increased weight and disrupted center of gravity
Solution Approach 1:
The patent extracts the light source unit from its conventional location and repositions it to the vehicle body frame, specifically utilizing the space between the head pipe and pivot shaft. This extraction and relocation reduces the impact on the vehicle's center of gravity and traveling performance while maintaining the lighting function.
Solution Approach 2:
The patent utilizes the vertical space dimension within the vehicle body frame, positioning the light source unit in the space between the head pipe and pivot shaft. This dimensional utilization allows effective placement without increasing horizontal footprint or significantly affecting weight distribution.
2Reliability
If a conventional light source unit is used in a saddle riding vehicle, then the lighting function is achieved, but the vehicle body space is insufficient for effective disposal
Solution Approach 1:
The patent nests the light source unit within the existing vehicle body frame structure, specifically utilizing the space between the head pipe and pivot shaft. This nesting approach allows the lighting apparatus to be incorporated without requiring additional external space, effectively using the vehicle's internal volume.
Solution Approach 2:
The patent utilizes the vertical space dimension within the vehicle body frame, positioning the light source unit in the space between the head pipe and pivot shaft. This dimensional utilization allows effective placement without increasing horizontal footprint.
3Weight of moving object
If the laser light source is disposed between the head pipe and pivot shaft, then the mass concentration and traveling performance are improved, but the cooling efficiency may be reduced due to enclosed position
Solution Approach 1:
The patent employs a heat dissipation fin structure that acts as a thermal management component. The fin extends toward the exterior of the vehicle body, providing a thermal pathway for heat dissipation while maintaining the compact positioning of the laser light source between the head pipe and pivot shaft.
4Device complexity
If the light source unit is integrated with the driving unit, then the number of parts and costs are reduced, but the maintenance complexity may increase
Solution Approach 1:
The patent integrates the laser light source and the driving unit into a single assembled unit, reducing the total number of separate parts and simplifying the overall structure. This merging reduces assembly complexity and potential failure points while maintaining ease of replacement as a modular unit.
