Motorcycle Storage Box Lid Layout to Avoid Handle Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional straddled vehicles with storage boxes have a lid portion that moves upward significantly when opened and closed, potentially interfering with the handle and requiring a large vehicle width due to the hinge being outside the opening, which affects aesthetics and security.
Innovation Solution
The storage box is positioned below the handle's turning trajectory with a shaft portion extending in the vehicle back-and-forth direction, limiting the lid's upward movement and incorporating a lid cover to enhance security and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hinge portion is provided outside the opening in the vehicle width direction, then the lid portion can be pivotally supported, but the lid portion performs a large upward moving action when opened and closed, potentially interfering with the handle
Solution Approach 1:
The hinge portion is repositioned from the vehicle width direction to the vehicle up-down direction, changing the dimension of rotation. This allows the lid portion to pivot without performing large upward movements that would interfere with the handle, while still maintaining pivotable access to the storage box
2Ease of operation
If the hinge portion is provided outside the opening in the vehicle width direction, then the lid portion can be supported, but the vehicle width must be increased to accommodate the hinge and lid movement
Solution Approach 1:
By relocating the hinge portion to extend in the vehicle up-down direction rather than the vehicle width direction, the patent eliminates the need for increased vehicle width to accommodate hinge movement. The lid portion pivots within the vertical dimension, preserving the vehicle's compact width while maintaining full lid functionality
3Ease of operation
If the shaft portion extends in the vehicle width direction, then the lid can be pivotally supported, but the vehicle width direction is enlarged
Solution Approach 1:
The shaft portion is reoriented to extend in the vehicle up-down direction instead of the vehicle width direction. This dimensional change allows the shaft to provide pivotal support for the lid while occupying vertical space rather than lateral space, thereby preventing enlargement of the vehicle width
