Injection-Molded Windshield Washer Chip With Integral Outlet Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windshield washer system chips with a two-part design face limitations in defining spray beam directions and often experience sealing issues due to their construction.
Innovation Solution
A chip designed for windshield washer systems, injection-molded with an integral outlet opening and edge, allowing for flexible spray beam direction adjustment, including vertical angles, and featuring an oscillation structure with separate output channels for uniform spray generation, eliminating the need for complex chip holder modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a two-part chip design is used, then the chip can be assembled into the chip holder, but sealing problems arise and spray direction definition is limited
Solution Approach 1:
The patent merges the chip body and outlet opening into a single integral component formed by injection molding. The outlet opening is directly formed in the chip body with a continuously delimited opening edge, eliminating the need for separate sealing components between multiple parts. This integration resolves the sealing problems associated with two-part designs while maintaining adaptability for spray direction control through the integrated structure.
2Ease of manufacture
If a two-part chip design is used, then assembly is possible, but the device complexity increases due to additional sealing requirements
Solution Approach 1:
The injection molding process creates an integral chip body with the outlet opening directly formed therein, eliminating the need for separate sealing components, gaskets, or bonding operations. The continuously delimited opening edge is formed as part of the monolithic chip structure, significantly reducing assembly steps and device complexity while maintaining ease of manufacture through the molding process itself.
3Adaptability or versatility
If the outlet opening is formed integrally by injection molding, then spray beam direction can be changed in any direction including vertical, but the manufacturing process becomes more precise
Solution Approach 1:
The patent utilizes the injection molding process to directly form the outlet opening with a centrally inclined axis at a specific angle relative to the chip holder base. By changing the geometric parameters of the molded opening during the molding process itself, the spray beam direction can be adjusted in any direction including vertical angles, while the precision is achieved through the molding process capabilities rather than post-manufacturing adjustments.
