Universal Wiper Adapter With Multi-Plane Arm Fastening
Solution Overview
Problem
Automotive wiper systems require different adapters for each type of wiper arm, leading to increased costs and complexity in selecting the correct adapter for wiper blade installation.
Innovation Solution
A universal connection device with a multi-directional adapter that can be removably fixed to a connection module, featuring fastening means in longitudinal, vertical, and transverse directions, allowing it to accommodate multiple types of wiper arms, including hook-type and side-fixing arms, through a combination of studs, locking tabs, and through-holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different adapters are designed for each type of wiper arm, then the compatibility with specific wiper arm types is improved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The adapter is designed with multiple fastening means including at least one first fastening means and at least one second fastening means, allowing a single adapter to accommodate different types of wiper arms (hook-type and side-fixing) through selectable fastening planes, eliminating the need for multiple specialized adapters
2Reliability
If different adapters are designed for each type of wiper arm, then the specific connection requirements are met, but the ease of operation and selection process deteriorate
Solution Approach 1:
The adapter provides multiple fastening planes (first and second fastening planes) that can accommodate different wiper arm types, allowing users to install the same adapter on various arm types without needing to select different adapter variants, thereby simplifying the installation process while maintaining reliable connection
3Adaptability or versatility
If multiple fastening planes are provided in multiple directions, then the adaptability to different wiper arm types is improved, but the structural complexity of the adapter increases
Solution Approach 1:
The adapter structure is segmented into distinct fastening means (first fastening means and second fastening means) with different fastening planes, allowing each segment to serve specific directional fastening requirements while maintaining overall structural simplicity through modular design
