Windscreen Wiper Cap Integrating Support and Fixing Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assembling and locking windscreen wipers to windscreen wiper arms require complicated procedures, making the process time-consuming and difficult.
Innovation Solution
A cap design that integrates support and fixing means, such as reliefs and protuberances, allows for simple assembly and locking onto the windscreen wiper arm's transverse pin, facilitating easy mounting and dismantling without the need for complex rotational movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complicated rotational movements are required between the cap and connector for assembly and locking, then the connection can be secured, but the assembly procedure becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple functions (support, fixing, and locking) into a single integrated cap structure. The cap simultaneously provides support means for the terminal segment and fixing means for the transverse pin, eliminating the need for separate components and complex assembly procedures while maintaining secure connection.
Solution Approach 2:
The cap is divided into distinct functional zones: an upper part for covering and protection, a lower part with support means for the terminal segment, and fixing means for the transverse pin. This segmentation allows each part to perform its specific function independently while contributing to the overall secure connection through simple assembly.
2Reliability
If multiple separate components are used for support and fixing, then the connection can be secured, but the device complexity increases
Solution Approach 1:
The patent merges the support means and fixing means into a single cap component. Instead of using separate support elements and fixing elements, the cap integrates both functions, reducing the total number of components while maintaining the security of connection through its dual-functional design.
3Reliability
If traditional assembly methods with rotational movements are used, then the connection can be secured, but the assembly time increases
Solution Approach 1:
The integrated cap design allows support and fixing functions to be achieved in a single assembly motion without rotational movements. The cap can be directly positioned and secured on the connector, eliminating time-consuming rotational steps while maintaining connection security through its combined functional structure.
