Modular Wiper Blade Mounting Base for Universal Arm Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
After-market wiper blade manufacturers face challenges in providing a cost-efficient and reliable connection system that can accommodate various types of wiper arms, as existing solutions like multi-arm connectors and removable mounting bases are not universally compatible.
Innovation Solution
A modular wiper blade system featuring detachable mounting bases with retaining projections, guiding channels, locking legs, and connecting devices like rivets, which can interchangeably attach to primary frames and wiper arms, ensuring secure and versatile connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a removable mounting base is used to connect to various wiper arms, then adaptability is improved, but connection reliability deteriorates
Solution Approach 1:
The mounting base is designed with a universal interface system comprising a primary frame with multiple retaining projections and corresponding guiding channels. This configuration allows the same mounting base to securely connect to different types of wiper arms (such as J-hook, U-channel, and traditional blade arms) while maintaining reliable connection through standardized geometric interfaces that ensure proper alignment and secure attachment.
2Adaptability or versatility
If multiple connection components are added to achieve universal compatibility, then adaptability is improved, but device complexity increases
Solution Approach 1:
The mounting base integrates multiple connection functions into a single unified structure. The primary frame combines retaining projections, guiding channels, and locking features into one monolithic component that interfaces with different wiper arm types. This merging approach achieves universal compatibility without requiring multiple separate adapters or complex assembly mechanisms, thereby reducing overall device complexity while maintaining adaptability.

AI summary
A wiper blade with a modular mounting base, having a wiper strip and a primary frame. The primary frame may be provided with a recessed portion having a base portion, a proximal end and a distal end, and may further be provided with a projection disposed on the proximal end, and with receiving holes on the base portion. The primary frame is capable of securing a mounting base having a bottom, a proximal end and a distal end such that one or more locking legs descending from the bottom of the mounting base can engage the receiving holes in the bottom portion of the primary frame, and such that the projection on the proximal portion of the recessed portion engages a guiding channel on the proximal end of the mounting base.
