Wiper Blade Adapter Locking for Multiple Drive Arm Types
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle windshield wiper connection devices require multiple adapters to accommodate different types of drive arms, leading to redundancy and inefficiency, as they cannot seamlessly connect to various drive arm configurations without interchanging adapters.
Innovation Solution
A connection device comprising a connector and two adapters, where the adapters' superimposed locking members allow the device to securely attach to a second type of drive arm distinct from the first, enabling flexible and efficient assembly by transitioning between blocking and mounting positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different adapters are used to accommodate different drive arm configurations, then adaptability is improved, but device complexity increases due to redundancy
Solution Approach 1:
The adapter is designed with a universal structure that can accommodate multiple drive arm configurations through a single device. The adapter includes a housing with a receiving space that can accept different types of drive arms, and a locking mechanism that can secure various drive arm types, eliminating the need for multiple specialized adapters.
Solution Approach 2:
The adapter incorporates a nested structure where the locking mechanism is integrated within the housing. The locking member can be positioned in different states (locked or unlocked) and is contained within the adapter housing, allowing compact design while maintaining multiple functions.
2Adaptability or versatility
If multiple adapters are interchanged to connect to different drive arms, then versatility is improved, but loss of time occurs during adapter interchange
Solution Approach 1:
The adapter incorporates a dynamic locking mechanism that can transition between locked and unlocked states. The locking member is designed to be movable, allowing quick engagement and disengagement from different drive arm configurations without requiring complete adapter removal and replacement.
Solution Approach 2:
The adapter is pre-configured with a receiving space and locking mechanism that are designed to accommodate multiple drive arm types. The locking member is positioned and structured in advance to enable rapid securing of different drive arms without requiring intermediate adjustment steps.
3Ease of operation
If locking members are made retractable between locking and mounting positions, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is merged with the adapter housing structure. The locking member is integrated into the housing and works in conjunction with the receiving space, combining multiple functions (locking, mounting, and positioning) into a single unified mechanism rather than separate components.
Solution Approach 2:
The locking mechanism is designed to be self-actuating through the movement of the locking member between locked and unlocked positions. The mechanical design allows the locking member to engage or disengage automatically when the adapter is positioned correctly on the drive arm, reducing the need for additional actuation mechanisms.
