Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windshield wiper connecting devices are limited in their ability to adapt to different wiper arm structures, making it difficult for consumers to install various types of wiper arms without specialized tools or modifications.
Innovation Solution
A windshield wiper connecting device featuring a base with a slot and notches, a connector with a movable cap and bulge half-ring, and a functional external cap, allowing for adaptable installation of wiper arms with different structures through a combination of rivet joints and resilient strips for secure and tool-free assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed-connection means is used in the connector, then the connection is secure and reliable, but the adaptability to different wiper arm structures is limited
Solution Approach 1:
The connector is divided into multiple functional components: a base portion for mounting on the wiper blade, a connector portion with specific geometric features (concave surfaces, notches, flanged lips), and a cap portion that secures the connection. This segmentation allows each part to perform its specific function while collectively providing both reliability and adaptability.
Solution Approach 2:
The connector is designed with universal features that can accommodate different wiper arm structures. The base portion can be mounted on various wiper blade types, and the connector portion's geometric features (concave surfaces, notches, flanged lips) can interface with multiple wiper arm designs, making the same connector applicable to diverse wiper systems.
2Adaptability or versatility
If a complex connector structure is used to accommodate multiple wiper arm types, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The connector is divided into multiple functional components: a base portion for mounting on the wiper blade, a connector portion with specific geometric features (concave surfaces, notches, flanged lips), and a cap portion that secures the connection. This segmentation allows each part to perform its specific function while collectively providing both reliability and adaptability.
Solution Approach 2:
Different portions of the connector have specialized geometric features tailored to specific functions: the base portion has mounting holes and flanged lips for secure attachment, the connector portion has concave surfaces and notches for interfacing with wiper arms, and the cap portion has pressing blocks for securing. Each local area is optimized for its specific role, achieving high adaptability without overall complexity.
3Reliability
If specialized tools are used for installation, then the connection reliability improves, but the ease of operation deteriorates
Solution Approach 1:
The connector is designed to be self-installing without requiring specialized tools. The cap portion can be manually pressed onto the connector portion, and the pressing blocks automatically secure the connection. The geometric features (notches, flanged lips, concave surfaces) guide the assembly process and ensure proper alignment, allowing consumers to install the connector themselves while maintaining high connection reliability.
