Straddled Vehicle Headlight Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing straddled vehicles with adjustable headlights require careful fastening of bolts to maintain the adjusted orientation, making the fixing process troublesome and inconvenient.
Innovation Solution
The straddled vehicle design incorporates a headlight with a first attachment portion and a second attachment portion, supported by stays with bolt holes that include long holes for forward and rearward adjustment and elastic holes for post-fastening movement, allowing for easy adjustment and fixing of the headlight orientation without needing to fasten all bolts simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If long holes are used in both bolt holes to enable adjustment, then lateral orientation adjustment is possible, but both bolts must be fastened carefully after adjustment making the fixing process troublesome
Solution Approach 1:
The bolt holes are segmented into two distinct types: long holes for adjustment and elastic holes for fixing. This segmentation allows the adjustment and fixing functions to be separated, enabling easy orientation adjustment through long holes while the elastic holes automatically secure the position without requiring careful fastening operations.
Solution Approach 2:
The invention changes the physical parameter of the bolt hole from a uniform circular shape to two different shapes: long holes (elongated) for adjustment and elastic holes (circular with elastic material) for fixing. This parameter change enables the bolt holes to have different functions - the long holes allow movement while the elastic holes provide automatic securing.
2Reliability
If all bolts are fastened to fix the headlight orientation, then the orientation is securely fixed, but the fixing process becomes time-consuming and troublesome
Solution Approach 1:
The elastic holes perform the fixing function automatically through the elastic deformation of the inserted material. When a bolt is inserted into an elastic hole, the elastic material deforms and then secures the bolt in place, providing self-service fixation without requiring additional fastening operations or careful adjustment by the operator.
Solution Approach 2:
Instead of using traditional fastening methods where bolts must be carefully tightened to fix the orientation, the invention inverts the approach by using elastic holes that automatically secure the bolt through elastic deformation. The fixing action happens automatically when the bolt is inserted, rather than requiring a separate careful fastening step.
3Adaptability or versatility
If long holes are used in stay bolt holes, then headlight can be moved forward and rearward for adjustment, but the bolts must be fastened carefully not to displace the orientation
Solution Approach 1:
The bolt holes are segmented into long holes for adjustment and elastic holes for fixing. This segmentation allows the adjustment and fixing functions to be separated, enabling easy orientation adjustment through long holes while the elastic holes automatically secure the position without requiring careful fastening operations.
Solution Approach 2:
The elastic material in the elastic holes acts as an intermediary between the bolt and the headlight stay. This intermediary provides a compliant connection that allows adjustment movement through the long holes while automatically securing the final position, eliminating the need for careful bolt fastening.
