Screen Mounting Structure for Saddle Riding Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen mounting structures for saddle riding vehicles limit design freedom and appearance due to the need for elongate slot-like mounting holes, which require covering and reduce aesthetic appeal.
Innovation Solution
A screen mounting structure featuring a screen stay with a groove portion that opens downwardly, allowing the screen to be moved downwardly without requiring slot-like holes in the screen, using a clip member with a collar and nut mechanism for secure attachment, enhancing design flexibility and appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If elongate slot-like mounting holes are used to allow downward movement of the screen, then the screen can be moved downward when load is applied, but the appearance is degraded and design freedom is reduced due to the need for covers
Solution Approach 1:
The mounting hole is divided into two functional parts: a circular upper portion for bolt attachment and a groove portion extending downward for load-bearing movement. This segmentation allows the screen to move downward through the groove while the circular portion maintains a clean appearance without requiring covers.
Solution Approach 2:
The mounting structure transitions from a two-dimensional slot-like hole to a three-dimensional groove portion that extends downward from the supporting seat. This dimensional change allows downward movement functionality while maintaining aesthetic appearance at the surface level.
2Ease of operation
If elongate slot-like mounting holes are used, then downward movement is enabled, but the number of parts increases due to required cover members
Solution Approach 1:
The cover member, which was previously required to hide the slot-like mounting hole, is completely removed from the design. The groove portion inherently provides both functionality and aesthetic appearance, eliminating the need for additional cover parts.
Solution Approach 2:
The groove portion serves multiple functions simultaneously: it enables downward movement when load is applied, provides structural support, and maintains aesthetic appearance without requiring separate cover components. This multi-functionality reduces the total number of parts.
3Ease of operation
If elongate slot-like mounting holes are used, then downward movement is enabled, but manufacturing and assembly complexity increases
Solution Approach 1:
The mounting hole is segmented into a circular upper portion for simple bolt attachment and a groove portion for load-bearing movement. This segmentation simplifies manufacturing compared to creating elongate slots, while the groove can be easily formed through machining or molding processes.

AI summary
A screen (38) is mounted on a supporting seat portion of a screen stay (50). A clip member (63) is mounted on the supporting seat portion. The clip member (63) includes a front plate portion, a rear plate portion, and a collar member (80) that is mounted so as to penetrate through the front plate portion and the rear plate portion. The collar member (80) includes a flange portion, a collar main unit, a bolt hole through which a bolt passes in the collar main unit and the flange portion, and a nut buried in the collar main unit at an end portion of the bolt hole. When the bolt is screwed into the nut, the screen (38) is clamped onto the supporting seat portion. However, this clamping can be overcome by application of the predetermined load, allowing the screen to be moved downwardly.
