Universal Wiper Blade Clip Accommodation for Multiple Arm Types
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper blade apparatuses are limited by specific mount types, making it difficult for users to adapt them to different vehicle types, leading to compatibility issues and restricted user choice.
Innovation Solution
A wiper blade apparatus with a lever member and clip member design that accommodates various wiper arm types, including U-hook, pin arm, and slide arm, through a square-shaped clip accommodation hole and popping grooves, allowing for easy mounting and adaptation to different vehicle configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an exclusive clip member suitable for a specific vehicle kind is applied to the wiper blade, then the wiper blade can be firmly fixed to the corresponding wiper arm, but it becomes impossible to mount the wiper blade on wiper arms of different types
Solution Approach 1:
The wiper blade apparatus is designed with a universal mounting structure that can accommodate multiple wiper arm types (U-hook, pin arm, and slide arm types) through a single clip member design. The clip member includes a clip accommodation hole with a specific cross-sectional shape that can receive different mount structures, enabling one wiper blade to serve multiple vehicle types and wiper arm configurations.
2Ease of operation
If a specific mount structure is designed for a particular wiper arm type, then the mounting process is simple and reliable, but the user cannot choose wiper blades according to personal preference when the vehicle's wiper arm type is fixed
Solution Approach 1:
The clip member is designed as a multi-functional component that can accommodate various wiper arm mount types through its specially shaped clip accommodation hole. This allows users to freely select and mount different wiper blade apparatuses according to their preferences regardless of the vehicle's wiper arm type, while maintaining simple and reliable mounting operations.
3Reliability
If the clip accommodation hole has a specific shape for a particular wiper arm type, then the clip member can be securely mounted, but it cannot accommodate other wiper arm types
Solution Approach 1:
The clip accommodation hole is designed with a universal cross-sectional shape that can securely receive different wiper arm mount types. The hole's geometry allows it to accommodate U-hook, pin arm, and slide arm types while maintaining secure mounting for each type through the same basic structure.
Solution Approach 2:
The clip member design incorporates adjustable parameters and flexible structural features that allow it to adapt to different wiper arm types. The clip accommodation hole's dimensions and shape characteristics can accommodate variations in mount type while maintaining secure fixation through the same basic mounting mechanism.

AI summary
Provided is a wiper blade apparatus on which various mount types of wiper arms are capable of being assembled. The wiper blade apparatus includes a lever member supporting a wiper lip, the lever member and a clip member coupled to the lever member. The lever member includes a clip accommodation hole, a first mount hole and a first popping groove. An inner wall of the first popping groove is separated from the lever member by a force of about 3 kgf to about 5 kgf that is applied in a width direction of the lever member to form a hole through which the first popping groove faces the first mount hole, and a pin arm type wiper arm or a slide arm type wiper arm is mounted by passing through the first mount hole and the first popping groove.
