Front Fork Through Hole for Headlight Optical Axis Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In saddle-ride type vehicles, the limited space behind the headlight and dense component arrangement make it difficult to create a reliable tool path for adjusting the optical axis, leading to interference and reduced clearances.
Innovation Solution
A through hole in the lower bracket of the front fork allows a tool to access the optical axis adjusting screw from below, providing a reliable tool path even when space is limited or components are densely disposed, enhancing adjustability and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If components related to the headlight are densely disposed to enhance brisk handling, then handling performance is improved, but the space on the back side of the headlight is reduced and tool interference with the vehicle body increases
Solution Approach 1:
The patent creates a tool path that extends in a different spatial dimension by routing the tool path through the front fork structure. Instead of requiring direct rearward access to the headlight, the tool path utilizes the vertical and lateral space created by the front fork's tubular bodies, allowing tool insertion from a different direction and resolving the space constraint caused by dense component disposition.
2Speed
If the headlight is disposed adjacently to the head pipe to enhance brisk handling, then handling performance is improved, but clearances among components are reduced and tool path production becomes difficult
Solution Approach 1:
The front fork acts as an intermediary structure that facilitates tool access to the optical axis adjusting screw. The tool path is configured to pass through or alongside the front fork's tubular bodies, using this intermediate structure to bridge the gap between the externally accessible area and the headlight's optical axis adjusting mechanism, thereby simplifying the overall tool path configuration despite adjacent component disposition.
3Adaptability or versatility
If a tool path is created for optical axis adjustment, then adjustability is improved, but structural strength or appearance may be compromised
Solution Approach 1:
The tool path is configured to utilize existing structural features of the front fork, such as the tubular bodies and bracket structures, rather than creating new openings or modifications. The path routes through spaces already present in the front fork design, maintaining the structural integrity and appearance of the front fork while providing the necessary access for optical axis adjustment.
