Universal Wiper Arm Connector with Guide Bar and Retention Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windshield wiper frame connectors are costly, difficult to assemble, and unable to securely accommodate hook-type wiper arms, leading to instability and premature failure.
Innovation Solution
A versatile windshield wiper bridge and connector assembly with a guide bar and cutout portion that allows easy assembly and disassembly of hook-type wiper arms, accommodating various arm types including pin, bayonet, and hook arms, using retention tabs and a cantilevered release tab for secure and efficient connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional wiper frame connector with multiple slots and L-shaped recess is used to accommodate both hook-type and pin-type arms, then versatility is improved, but manufacturing cost and assembly difficulty increase due to complicated structure
Solution Approach 1:
The adaptor is designed with a universal interface that can accommodate multiple types of wiper arms (hook-type, pin-type, bayonet, two-hole bayonet, reverse hook) through a single standardized structure. The adaptor body includes a guide bar and retention mechanism that works with all these variations, eliminating the need for multiple specialized connectors.
Solution Approach 2:
The adaptor serves as an intermediary component between the wiper frame and various wiper arm types. It translates different arm configurations into a unified connection interface, allowing the frame to work with diverse arm types without requiring complex multi-slot structures. The adaptor mediates the connection by providing standardized attachment points.
2Adaptability or versatility
If a conventional wiper frame connector with deep slots is used to receive pin-type arms, then pin-type arm compatibility is improved, but stability deteriorates due to depth difference between blade unit pin and rolled bushing
Solution Approach 1:
The invention replaces the deep slot mechanical reception system with a guide bar and retention tab mechanism. Instead of relying on slot depth to accommodate different pin positions, the guide bar provides lateral guidance while retention tabs secure the connection, eliminating the stability issues caused by depth variations.
3Ease of operation
If a conventional wiper frame connector without locking members is used to receive hook-type arms, then ease of assembly is improved, but reliability deteriorates due to lack of secure locking
Solution Approach 1:
The retention tabs are designed to automatically engage with hook-type arms during assembly without requiring additional locking actions. The tabs flex outward during installation to allow easy insertion, then spring inward to securely lock the arm in place, providing both ease of assembly and reliable locking through self-service mechanism.
