Non-Bracket Windshield Wiper: Simplified Design for Cost-Effective Manufacturing
Here’s PatSnap Eureka !
Summary
Problems
Conventional windshield wipers have a complex structure requiring multiple components and rivets, leading to high manufacturing costs and complicated assembly processes.
Innovation solutions
A non-bracket windshield wiper design featuring an H-shaped elastic metal bow strip with longitudinal crevices, holding strips, back rubber strips, a rubber wiper blade, and end caps, allowing for easy assembly and replacement without rivets, using a holder frame and packing member for mounting to a windshield.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a conventional bracket structure with multiple components and rivets is used, then the structural strength and stability are improved, but the device complexity and manufacturing cost increase
Why choose this principle:
The patent combines multiple separate components (bracket, arm holder frame, arms, extension strips) into a single integrated elastic metal bow strip. This merging eliminates the need for rivets and assembly operations, reducing device complexity while maintaining structural integrity through the continuous elastic material design.
Principle concept:
If a conventional bracket structure with multiple components and rivets is used, then the structural strength and stability are improved, but the device complexity and manufacturing cost increase
Why choose this principle:
The patent uses an elastic metal bow strip that functions as a composite structure, integrating the functions of multiple rigid components into a single flexible element. This composite approach allows the structure to maintain strength while eliminating complex joints and connections.

Abstract
A non-bracket windshield wiper includes an H-shaped and smoothly arched elastic metal bow strip having a middle neck and two longitudinal crevices at two sides of the neck, a holder frame mounted with a packing member and riveted to the middle part of the elastic metal bow strip for mounting to a windshield, two holding strips respectively coupled to the longitudinal crevices of the elastic metal bow strip, two back rubber strips respectively coupled to two top engagement structures of the holding strips, a rubber wiper blade coupled to two bottom engagement structures of the holding strips, and two end caps respectively capped on the two ends of the elastic metal bow strip.
