Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper blade connection devices to wiper arms lack versatility, are costly to manufacture, and prone to coupling issues that can lead to reliability problems, especially at high speeds, due to complex structures and limited compatibility with various wiper arm types.
Innovation Solution
A device featuring a bracket with a wiper blade coupled to its lower portion and an adapter that connects to the wiper arm, utilizing a fitting and sliding coupling structure between the wiper blade's frame, spoilers, and bracket, allowing for easy assembly and secure attachment of multiple wiper arm types, while maintaining a stable coupled state even at high speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a specific type of wiper arm connection device is used, then it can be securely coupled to that specific wiper arm type, but it cannot be used with other types of wiper arms, limiting versatility
Solution Approach 1:
The connection device is designed with a universal adapter that can interface with multiple types of wiper arms (J-hook, U-hook, side pin, bayonet, top lock, side lock) through a single standardized connection mechanism, eliminating the need for multiple specialized connection devices
2Strength
If a complex coupling structure is used to secure the wiper blade to the wiper arm, then coupling strength is improved, but manufacturing cost and assembly time increase
Solution Approach 1:
The connection device is divided into separate functional components: a bracket that attaches to the wiper blade frame, and an adapter that connects to the wiper arm. This segmentation allows each component to be manufactured independently using simple processes, then assembled through a straightforward coupling mechanism that provides secure attachment without complex structures
Solution Approach 2:
The adapter serves as an intermediary component that mediates between the wiper blade bracket and the wiper arm, providing a standardized interface that simplifies the connection while maintaining coupling strength through its ability to accommodate various wiper arm types
3Reliability
If a complex coupling structure is used to attach the wiper blade frame to the bracket, then coupling strength is improved, but the structure becomes complicated and assembly time increases
Solution Approach 1:
The coupling structure is segmented into distinct functional elements: positioning protrusions on the bracket that fit into corresponding grooves on the frame, and support protrusions that provide additional stabilization. This segmentation creates a reliable multi-point connection that prevents lifting at high speeds while maintaining structural simplicity and ease of assembly
