Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wiper blade devices are limited by different mounting structures for various types of wiper arms, making it difficult for drivers to replace wiper blades with new types that match their vehicle's wiper arm configuration.

Innovation Solution

A clip member with a rotatable design, featuring a combination groove unit, first and second mounting units, and a moving prevention bead, allowing it to accommodate and secure multiple types of wiper arms, including slide and pin arm types, by being mounted at the center of the wiper blade device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an exclusive clip member is designed for each wiper arm type (U-hook, pin arm, slide arm), then the mounting reliability for each specific type is improved, but the adaptability to accommodate various wiper arm types deteriorates

Engineering Contradiction:

Improvemounting reliabilityVSAvoidadaptability to various wiper arm types

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The clip member is designed with multiple mounting units (first mounting unit with concave groove, second mounting unit with passing hole, third mounting unit with flange structure) that can accommodate different wiper arm types (slide arm, pin arm, U-hook types) using a single universal clip member design, eliminating the need for multiple exclusive clip members

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a single universal clip member design is used to accommodate various wiper arm types, then the adaptability is improved, but the mounting precision and reliability for specific types may deteriorate

Engineering Contradiction:

Improveadaptability to various wiper arm typesVSAvoidmounting precision

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Each mounting unit within the clip member is designed with specific local structures optimized for particular wiper arm types: the concave groove structure for slide arm types, the passing hole for pin arm types, and the flange structure for U-hook types, ensuring precise mounting for each specific type while maintaining overall universality

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If multiple mounting units are integrated into a single clip member, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:

Improveadaptability to various wiper arm typesVSAvoidclip member structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple mounting units (concave groove, passing hole, flange structure) that would traditionally require separate clip members for different wiper arm types are merged into a single integrated clip member body, allowing one component to serve multiple mounting functions

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A clip member for mounting various types of wiper arms including: a main body; a combination groove unit that is detachably combined with a lever member; a first mounting unit that is a concave groove formed in an upper surface of the main body, and is combined with a slide-arm wiper arm; a second mounting unit that is a hole passing through a sidewall of the main body in the width direction of the main body to be combined with a pin unit of a slide-arm wiper arm or a pin-arm wiper arm; and a third mounting unit that is formed on an outer side from one of both side surfaces of the main body opposite the wiper arm and that wraps around a sidewall of the clip in the manner of a hat.
