Integrally-Molded Headlight Stay for Motorcycle Aiming Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headlight support structures for saddle riding vehicles face challenges in attachment accuracy and size due to variations in attachment accuracy of stays to the bottom bridge and the placement of aiming mechanisms within the headlight case, leading to increased headlight size and space occupation.
Innovation Solution
A headlight support structure featuring an integrally-molded headlight stay that supports the headlight in a swingable manner, with the aiming mechanism mounted outside the headlight and within the stay, utilizing elastic bodies and a compact aiming mechanism placement to enhance accuracy and reduce size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the aiming mechanism is placed within the headlight case, then the headlight can be adjusted for illuminating angle, but the headlight size increases and occupies more space
Solution Approach 1:
The aiming mechanism is extracted from the headlight case and mounted separately on the vehicle body. This allows the headlight case to maintain a compact size while the aiming mechanism remains accessible for adjustment operations.
2Strength
If separate left and right stays are used to attach the headlight case to the bottom bridge, then the headlight can be supported, but variations in attachment accuracy reduce the overall attachment precision
Solution Approach 1:
The left and right stays are merged into a single integrally-molded headlight stay. This eliminates accumulation of attachment errors between separate components and ensures consistent positioning relative to the bottom bridge, while the integral structure maintains sufficient support strength.
3Adaptability or versatility
If multiple separate components are used for headlight support and aiming mechanism, then each component can be optimized independently, but the overall device complexity increases
Solution Approach 1:
The headlight stay and aiming mechanism mounting structure are combined into a single integrally-molded component. This reduces the total number of parts and assembly steps while maintaining the ability to optimize the overall structure for both support and adjustment functions.
