Wiper Blade Adapter Elastic Latching and Securing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper blade adapter devices for motor vehicle windscreen wiper systems lack a secure and efficient coupling mechanism that simplifies assembly while ensuring a stable connection between the wiper blade adapter and the wiper strip unit.
Innovation Solution
The wiper blade adapter device incorporates a spring-elastic latching means and a securing means that are deflected in different directions during assembly, allowing for a secure and space-saving coupling, with the latching means pivoting parallel to the assembly direction and the securing means pivoting perpendicularly, ensuring a stable and reliable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a spring-elastic latching means is used for coupling the wiper blade adapter to the wiper strip unit, then the coupling can be achieved with simple structure, but the security and stability of the connection is insufficient
Solution Approach 1:
The coupling mechanism is divided into two independent but coordinated components: a latching means for initial coupling and a securing means for final stabilization. This segmentation allows each component to perform its specific function optimally while maintaining overall system simplicity
Solution Approach 2:
The securing means is arranged to act in a direction perpendicular to the latching means, adding a second dimensional constraint. This perpendicular arrangement enhances connection stability without increasing the complexity of the primary coupling mechanism
2Ease of operation
If traditional assembly methods are used without a securing means, then the assembly process is simple, but the assembly security and reliability are insufficient
Solution Approach 1:
Both the latching means and securing means are spring-elastic components that automatically engage and lock into their respective positions during the assembly process. The components self-secure without requiring additional fastening operations, maintaining ease of assembly while improving reliability
Solution Approach 2:
The latching means performs the preliminary coupling action first, bringing the components into engagement. Subsequently, the securing means activates to provide final stabilization. This sequential preliminary action ensures reliable assembly without complicating the overall process
3Volume of moving object
If the latching means and securing means are arranged in the same direction, then the structure is compact, but the latching means cannot be held securely in the locking position
Solution Approach 1:
The latching means and securing means are deliberately arranged asymmetrically in perpendicular directions rather than symmetrically in the same direction. This asymmetric perpendicular arrangement creates complementary constraint actions that securely hold the latching means in its locking position while maintaining compact overall dimensions
