Vehicle Wiper Spray Nozzle Segmented Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window-wiper systems for vehicles lack a simple and efficient method for disassembling and reassembling the spray nozzle, which complicates maintenance and replacement processes.
Innovation Solution
A spray nozzle design featuring removable fixing means with an independent actuating mechanism, such as a push-button, allows for disassembly from a mounting bracket, simplifying the design and operations, and incorporating a mounting bracket that can be positioned and fixed on a clevis of a window-wiper arm, utilizing systems like rail and slider or elastic snap-in mechanisms for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the spray nozzle is integrated as a single part with the mounting bracket, then the structural strength is improved, but the ease of repair deteriorates
Solution Approach 1:
The spray nozzle is divided into separate components including a mounting bracket and a spray nozzle body that can be independently assembled and disassembled. The mounting bracket includes fixing means such as clips or snap-fit mechanisms that allow the spray nozzle to be removably attached, enabling easy replacement or repair of the spray nozzle without replacing the entire integrated structure.
2Device complexity
If the spray nozzle is made as a single integrated part, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The spray nozzle assembly is segmented into a mounting bracket and a removable spray nozzle component. The mounting bracket includes fixing means such as elastic clips or snap-fit mechanisms that enable tool-free or simple manual assembly and disassembly operations, improving ease of operation while maintaining acceptable device complexity.
3Reliability
If the spray nozzle uses a permanent fixing mechanism, then the reliability is improved, but the ease of repair deteriorates
Solution Approach 1:
The fixing mechanism is designed as a removable connection system using elastic clips or snap-fit joints that provide reliable, vibration-resistant attachment during operation while allowing simple disassembly when needed for repair or replacement. The segmented design enables the spray nozzle to be detached from the mounting bracket without damaging either component.
Solution Approach 2:
The spray nozzle is designed as a replaceable component that can be easily detached from the mounting bracket using simple fixing means. When the spray nozzle wears out or needs upgrading, it can be quickly removed and replaced with a new or improved version, while the mounting bracket remains in place and can be reused.
