Vehicle Windshield Holder Mechanism for Tool-Free Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windshield adjustment systems for vehicles, such as motorcycles, require complex operations involving loosening and re-tightening screws to adjust the windshield height, necessitating tools and significant time and effort.
Innovation Solution
A windshield device with a support structure featuring a pair of stays for movable rising and lowering support and a separate holder for fixation, utilizing a cam lever and stopper mechanism to easily adjust and secure the windshield height without the need for complex screw operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix the windshield to support pillars, then the windshield can be securely fixed, but the adjustment process becomes complex and time-consuming
Solution Approach 1:
The support structure is divided into two independent functional components: stays for movable support and a holder for fixation. This segmentation allows the stays to handle the windshield weight and movement freely, while the holder independently provides secure fixation, eliminating the need for complex screw operations on support structures.
Solution Approach 2:
The holder acts as an intermediary component between the windshield and the vehicle body. It includes a stopper that moves along the rising and lowering direction and contacts the base portion to fix the windshield position. This intermediary mechanism simplifies the fixation process to a single operation rather than multiple screw fastening steps.
2Reliability
If multiple screws are used to fix the windshield to both support pillars, then stable fixation is achieved, but the number of operations and tools required increases
Solution Approach 1:
The holder integrates multiple fixation functions into a single component. It combines the base portion fixed to the vehicle body, the stopper for position fixation, and the operation member for controlling the fixation state. This merging reduces the overall structure from multiple screw-fastening support pillars to a single integrated holder mechanism.
Solution Approach 2:
The holder serves multiple functions: it provides fixation, enables easy adjustment, and maintains structural support. The stopper mechanism within the holder can move along the rising and lowering direction to fix the windshield at different heights, while the operation member controls the engagement and disengagement of the stopper, making the holder a multi-functional component that replaces multiple specialized parts.
3Reliability
If screws are used for windshield fixation, then reliable attachment is achieved, but adjustment time and effort increase significantly
Solution Approach 1:
The holder is pre-configured with the stopper and operation member in a ready state. The stopper is positioned to automatically contact the base portion when the windshield reaches the desired height, and the operation member is prepared to instantly engage or disengage the fixation. This preliminary arrangement eliminates the need for time-consuming screw loosening and tightening during adjustment.
Solution Approach 2:
The holder employs a dynamic stopper mechanism that can move along the rising and lowering direction rather than a static screw connection. The stopper transitions between engaged and disengaged states through the operation member, allowing rapid adjustment of the windshield position. This dynamic mechanism replaces the static, time-consuming screw fastening process with a quick mechanical engagement system.
