Universal Flat Wiper Blade Removable Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of standardization in flat windscreen-wiper blades leads to high production and distribution costs due to the need for specific connection means for different drive arms, resulting in a high price for consumers.
Innovation Solution
A linking support that can be solidly and rigidly attached to a removable connector, which can be coupled with various drive arms, allowing for universal compatibility and easy replacement based on wear cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If specific connection means are designed for each drive arm type, then adaptability to different drive arms is improved, but device complexity and production costs increase
Solution Approach 1:
The patent applies universality by designing a single standardized connector that can be used with multiple types of drive arms. The connector features a universal interface that accommodates different drive arm configurations through a common attachment mechanism, eliminating the need for multiple specialized connection means.
Solution Approach 2:
The patent segments the windscreen-wiper blade into modular components: a standardized connector and a replaceable wiping strip assembly. This segmentation allows the connector to remain constant while different wiping strip types can be attached, simplifying the overall system while maintaining adaptability.
2Adaptability or versatility
If multiple types of flat windscreen-wiper blades are produced for different drive arms, then adaptability is improved, but manufacturing costs increase
Solution Approach 1:
The standardized connector serves multiple functions across different drive arm types, allowing manufacturers to produce a single connector design that works universally. This reduces tooling costs, simplifies production lines, and eliminates the need to maintain multiple connector inventories.
Solution Approach 2:
The patent enables the wiping strip to be separately replaced while retaining the expensive connector. When the wiping strip wears out, only the inexpensive strip needs to be discarded and replaced, while the durable connector is recovered and reused, reducing overall replacement costs.
3Reliability
If the entire windscreen-wiper blade is replaced when the wiping strip wears out, then reliability is maintained, but loss of substance and cost increase
Solution Approach 1:
The windscreen-wiper blade is segmented into a permanent connector and a consumable wiping strip. This allows the strip to be independently replaced when worn, preventing the need to discard the entire assembly and reducing material waste.
Solution Approach 2:
The design enables selective discarding of only the worn wiping strip while recovering and reusing the durable connector. This extends the lifecycle of the valuable connector component and reduces overall waste.
