Wiper Connector Structure for Easy Blade Detachment on Nozzle Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper blades wear out over time, generate noise, and degrade wiping performance, necessitating frequent replacement, especially when integrated with wiper arms that have nozzles for spraying washing liquid, requiring improved adapter designs for efficient detachment.
Innovation Solution
A wiper connector with an insertion portion and fixing portion that includes first and second fasteners, allowing easy detachment from wiper arms with integrated nozzles, featuring a hook-shaped first fastener and cantilever-shaped second fastener to secure the wiper blade assembly, limiting movement in multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional adapter structure is used to connect wiper blade and wiper arm, then the wiper blade can be attached, but it is difficult to detach efficiently from wiper arms with integrated nozzles
Solution Approach 1:
The adapter is divided into multiple functional components: a first fastening portion with a hook-shaped fastener for vertical securing, and a second fastening portion with a cantilever-shaped fastener for longitudinal securing. This segmentation allows each portion to handle specific detachment movements independently, making removal efficient without requiring complex overall structure
Solution Approach 2:
The adapter incorporates elastic deformation capabilities in its fastening portions. The hook-shaped fastener elastically deforms to pass through the hole and secures vertically, while the cantilever-shaped fastener elastically deforms to engage with the rib and prevent longitudinal movement. This dynamic elasticity enables easy detachment through simple pressing actions
2Reliability
If the wiper blade is securely fixed to the wiper arm, then wiping performance is maintained, but the blade becomes difficult to replace periodically
Solution Approach 1:
The adapter is pre-installed on the wiper blade during manufacturing, forming an integrated assembly. This preliminary action allows users to simply detach the entire adapter-wiper blade assembly from the wiper arm without needing to manually disassemble or adjust complex fastening mechanisms during periodic replacement
Solution Approach 2:
The fastening system is segmented into two independent portions: the first fastening portion handles vertical securing through hole engagement, while the second fastening portion handles longitudinal securing through rib engagement. This segmentation allows simple pressing actions to simultaneously release both fastening mechanisms, enabling easy replacement while maintaining reliable fixing during operation
3Adaptability or versatility
If an adapter design is created for wiper arms with integrated nozzles, then compatibility is improved, but the adapter structure becomes more complex
Solution Approach 1:
The adapter is designed with universal compatibility for wiper arms featuring integrated nozzles. The insertion portion fits into the wiper arm's insertion hole, while the fastening portions engage with standard structural features (hole and rib) present in these arms. This multi-functional design achieves compatibility without requiring nozzle-specific customization
Solution Approach 2:
The adapter structure is segmented into an insertion portion for positioning and two independent fastening portions for securing. This segmentation allows each portion to interact with specific structural features of nozzle-integrated wiper arms without requiring the adapter to accommodate the entire complex nozzle assembly, thereby maintaining structural simplicity while achieving compatibility
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user convenience by facilitating easy and secure attachment and detachment of wiper blades, maintaining wiping performance and reducing noise, while allowing integration with wiper arms equipped with washing liquid nozzles.
Implementation Method 1
a second fastener caught by a rib provided inside the wiper arm, and the second fastener is provided to be elastically deformed and provided to be switched from a first state in which the first fastener is elastically deformed by the rib when passing through the hole to a second state in which the first fastener passes the rib and is restored to an original state
