Multi-Adapter for Vehicle Wiper Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle wiper adapters require an additional auxiliary member for compatibility with side pin-type arms, leading to increased production costs and user inconvenience due to the need for dedicated adapters for different arm types.
Innovation Solution
A multi-adapter with a body featuring multiple pin coupling portions and protrusions allows for secure coupling of side pin-type arms without an auxiliary adapter, using pin holes of varying sizes and protrusions to maintain a gap and prevent loose coupling, enabling compatibility with various arm types using a single adapter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional adapter is used for side pin-type arms, then compatibility is achieved, but an additional auxiliary adapter is required
Solution Approach 1:
The adapter body is designed with multiple pin coupling portions (first, second, and third pin coupling portions) that can accommodate different pin types and sizes. The protrusions on the side plates provide universal support for various arm configurations, allowing a single adapter to replace multiple dedicated adapters for different arm types.
Solution Approach 2:
The adapter body is divided into multiple functional segments including different pin coupling portions (through-holes, recesses, protrusions) that can independently engage with different types of arms. This segmentation allows each portion to handle specific coupling requirements while working together as a unified multi-functional adapter.
2Adaptability or versatility
If an auxiliary adapter is added for side pin-type arm compatibility, then coupling is achieved, but production cost increases
Solution Approach 1:
The invention merges the functions of multiple dedicated adapters (for different arm types and sizes) into a single adapter body. By integrating multiple pin coupling portions and protrusions into one component, the design eliminates the need to manufacture and inventory separate auxiliary adapters, thereby reducing production costs while maintaining compatibility with various arm types.
3Reliability
If a dedicated adapter is used for each arm type, then precise coupling is achieved, but user convenience decreases
Solution Approach 1:
The adapter body provides universal compatibility through multiple pin coupling portions and protrusions that can accommodate various arm types (U-shaped clip type, pin type, side pin type) without requiring users to select or swap between different dedicated adapters. This multi-functional design maintains precise coupling while significantly improving user convenience.

AI summary
The present invention relates to a multi-adapter for a vehicle wiper, comprising; a joining portion coupled to a wiper blade; a pair of side plates protruding from the joining portion such that the side plates are parallel to each other, wherein each of the side plates has: an inside with a hinge shaft; a plurality of pin coupling portions formed at the pair of side plates, and to which an arm with pins of different sizes are selectively coupled; and a plurality of protrusions formed on at least one of the pair of side plates so as to maintain a gap between the arm and the pair of side plates. The multi-adapter for a vehicle wiper according to the present invention has an adapter body with said plurality of pin coupling portions and said plurality of protrusions, thus enabling conventional side pin type arms, which require an additional auxililary member for connection, to be coupled to the adapter without using an auxiliary member. Thus, the multi-adapter of the present invention itself enables the arm to be coupled thereto, thereby improving user convenience and reducing manufacturing costs, and the multi-adapted of the present invention can be used for various types of arms.
