Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automotive vehicle manufacturers face the challenge of designing multiple adapters for different types of wiper arms, requiring users to select the correct adapter for each wiper, which is cumbersome and inefficient.
Innovation Solution
A universal connection device with a pivotable cover and elastically deformable tongue that can secure and unlock various wiper arms, allowing a single adapter to fit multiple arm types, featuring blocking means and a pivotable connection module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple adapters are designed for different wiper arm types, then each adapter can be specifically matched to its corresponding arm type, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent implements a universal adapter design where a single adapter body can accommodate multiple wiper arm types through a pivotable cover mechanism. The cover can be positioned in different angular orientations to engage with different arm configurations, allowing one adapter to perform multiple functions that previously required separate adapters for each arm type.
Solution Approach 2:
The adapter incorporates a dynamic cover that can pivot between different positions rather than being fixed in a single orientation. This dynamic element allows the adapter to adapt its configuration based on the specific wiper arm type being installed, enabling a single static adapter body to work with multiple varying arm designs.
2Adaptability or versatility
If users must select the correct adapter for each wiper arm type, then proper matching is ensured, but the ease of operation decreases due to selection complexity
Solution Approach 1:
The universal adapter eliminates the need for users to select from multiple different adapters by providing a single adapter that can accommodate various arm types. The pivotable cover automatically adapts to different arm configurations, simplifying the user operation from selecting the correct adapter to simply installing the universal adapter and adjusting the cover position.
Solution Approach 2:
The adapter system performs self-adjustment through the pivotable cover mechanism that can be positioned to match different arm types without requiring user knowledge or selection of specific adapter models. The design allows the single adapter to self-adapt to various configurations.
3Ease of operation
If a universal adapter design is implemented, then the ease of operation and manufacturing are improved, but the reliability of secure connection may be compromised
Solution Approach 1:
The pivotable cover provides both ease of installation and secure connection by allowing simple positioning during installation while maintaining rigid engagement with the wiper arm once positioned. The dynamic adjustment capability during installation does not compromise the static security of the final connection.
Solution Approach 2:
The blocking means incorporate curved or rounded features that engage with corresponding features on different wiper arm types, providing reliable mechanical engagement across multiple arm configurations. The curved geometry of the blocking means allows for tolerant fitting while maintaining secure connection.
