Windshield Wiper Adaptor With Rotating Two-Part Arm Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper devices struggle with secure and efficient attachment and detachment of the wiper arm, compromising ease of installation and maintenance.
Innovation Solution
A wiper device with an adaptor comprising two members, a first member with an insertion hole for the wiper arm and a second member that is vertically fitted and laterally rotated to engage with the first member, facilitating secure coupling and easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional single-piece adaptor is used, then the structure is simple, but the attachment and detachment of the wiper arm becomes difficult and time-consuming
Solution Approach 1:
The adaptor is divided into two separate members: a first member connected to the support member with an insertion hole, and a second member that can be vertically fitted and laterally rotated to engage with the first member. This segmentation allows the wiper arm to be easily inserted and secured through a simple rotational locking action, significantly improving ease of attachment and detachment while maintaining structural integrity
2Reliability
If a secure connection mechanism is implemented, then the reliability of the connection improves, but the ease of installation deteriorates
Solution Approach 1:
The first member is pre-configured with an insertion hole and engagement features that guide the wiper arm into the correct position. The second member is pre-designed with lateral rotation capability that automatically engages with the first member. This preliminary arrangement of engagement features ensures reliable connection while requiring minimal installation effort from the user
