Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper blade adapter devices lack a reliable and force-efficient locking mechanism that allows for compact design and high operational reliability, particularly in securing the wiper arm adapter and preventing undesired deflection during operation.
Innovation Solution
The wiper blade adapter device incorporates a locking mechanism with a resilient locking means that deflects during assembly in the direction of the adapter unit's longitudinal center plane, combined with an additional locking means, which provides a secure and compact coupling with the wiper arm adapter, ensuring reliable engagement and stability while allowing for flexible assembly and protection from weather influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is designed to be force-efficient and reliable, then operational reliability is improved, but device complexity increases
Solution Approach 1:
The locking means is designed as a resilient element that dynamically deflects during assembly and operation. It deflects at least partially in the direction of the longitudinal center plane during assembly, and can deflect laterally during operation to accommodate dimensional tolerances. This dynamic behavior provides reliable locking without requiring complex adjustment mechanisms.
Solution Approach 2:
The locking means utilizes elastic deformation as its operating principle. By changing the physical state of the locking means from rigid to resilient, the mechanism achieves reliable engagement through elastic deflection and recovery, simplifying the overall locking mechanism while maintaining high operational reliability.
2Volume of moving object
If the adapter unit is designed with a compact structure, then device size is reduced, but manufacturing complexity increases
Solution Approach 1:
The adapter base member is formed substantially or completely from a single plastics material using injection molding. The locking means, adapter unit, and base member are integrated into a unified structure, reducing the number of separate components and simplifying manufacturing while achieving a compact structural height.
Solution Approach 2:
The locking means is designed with specific geometric parameters that enable it to deflect in the direction of the longitudinal center plane during assembly. By optimizing the shape and dimensions of the locking means, the patent achieves compact structural height without requiring complex assembly procedures.
3Ease of operation
If the locking means deflects significantly during assembly, then ease of assembly is improved, but structural stability worsens
Solution Approach 1:
The locking means is designed to deflect dynamically during assembly in the direction of the longitudinal center plane, facilitating easy assembly. Once assembled, the resilient nature of the locking means allows it to return to its original position and maintain stable engagement, ensuring structural stability during operation.
Solution Approach 2:
The locking means is designed as a resilient element that can be deflected and recovered repeatedly without permanent deformation. This allows for easy assembly and disassembly operations while maintaining structural integrity and stability throughout the service life of the wiper blade adapter device.
