Wiper Device Cover Coupling Mechanism for Impact Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wiper devices face issues with the cover member separating from the wiper device during operation due to impact, compromising the stability and effectiveness of the wiper mechanism.
Innovation Solution
A wiper device design featuring a contact member, a pressing member with coupling units, and a cover member with supporting units, where the coupling units securely engage to prevent separation even under strong impact, utilizing a multi-level lever structure and coupling units that insert into and are hooked by the cover member's coupling holes to maintain engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple cover structure is used, then the device complexity is reduced, but the cover member separates under impact
Solution Approach 1:
The cover member is divided into a body portion and a separate supporting unit that extends from the body. The supporting unit includes a coupling hole that receives the coupling unit, creating a segmented structure that enhances engagement stability without significantly increasing overall complexity.
Solution Approach 2:
The coupling unit is inserted into the coupling hole of the supporting unit, creating a nested configuration where one component fits within another. This nesting approach provides secure engagement while maintaining a compact design.
2Reliability
If a secure coupling mechanism is added, then the cover member engagement stability is improved, but the device complexity increases
Solution Approach 1:
The coupling mechanism is segmented into distinct components: the coupling unit on the pressing member and the supporting unit with the coupling hole on the cover member. This segmentation allows for a focused, simple coupling design that provides reliable engagement without adding unnecessary complexity to the entire device.
Solution Approach 2:
The coupling unit acts as an intermediary element that connects the pressing member to the cover member. This intermediate component facilitates secure engagement while keeping the overall coupling mechanism simple and manageable.
