Motorcycle Windscreen Elevating Mechanism with Integrated Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saddle ride type vehicles with height-adjustable windscreens have complex configurations and high costs due to multiple components, making manual adjustment operationally challenging.
Innovation Solution
A windscreen elevating mechanism with a vertically movable shaft, an operation unit with a grip portion and flange portion, and abutment portions between the bracket and holder to improve operability, reduce costs, and simplify the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex height-adjustable windscreen structure is used, then the windscreen can be adjusted, but the number of components increases and cost increases
Solution Approach 1:
The operation unit integrates multiple functions into a single component: the grip portion enables manual operation, the flange portion prevents finger insertion, and the shaft provides vertical movement. This merging of functions reduces the number of separate components while maintaining windscreen adjustability
Solution Approach 2:
The bracket structure serves multiple purposes: it supports the windscreen, provides the shaft for vertical movement, includes the operation unit for adjustment, and incorporates the flange portion for safety. This multi-functionality reduces component count while achieving the adjustment capability
2Ease of manufacture
If manual adjustment is implemented to reduce cost, then component count decreases, but operability becomes difficult
Solution Approach 1:
The grip portion is specifically designed with a diameter and shape optimized for manual gripping, while the flange portion is designed with a larger diameter to prevent finger insertion. This local differentiation of qualities ensures both ease of operation and safety in the manual adjustment mechanism
Solution Approach 2:
The shaft acts as an intermediary element that translates the rotational or sliding motion of the operation unit into vertical movement of the windscreen. This mediator mechanism makes manual adjustment easier while maintaining a simple overall structure
3Object-affected harmful factors
If the flange portion is positioned inside the grip portion, then finger insertion is prevented, but the structure becomes more complex
Solution Approach 1:
The flange portion is integrated directly into the operation unit as a unified structure rather than being a separate component. This merging approach prevents finger insertion while avoiding the complexity of additional separate parts, maintaining structural simplicity

AI summary
Provided is a saddle ride type vehicle including a movable windscreen structure capable of improving operability at low cost. A shaft 67 is supported by a fixing member 53 so as to be vertically movable, the shaft 67 passes through a lower upright portion 56d of a screen attachment member 56 provided on the outer side in the vehicle width direction of the fixing member 53, and an operation unit 58 is slidably provided at the end portion of the shaft 67. The operation unit 58 includes a grip portion 58e gripped when being slid and a flange portion 58h disposed inside in the vehicle width direction of the grip portion 58e, the grip portion 58e includes an outer grip portion 58f disposed outside in the vehicle width direction and an inner grip portion 58g disposed inside in the vehicle width direction of the outer grip portion 58f, and the flange portion 58h is formed to have a larger diameter than the inner grip portion 58g.
