Wiper Blade Nozzle End Cap for Uniform Fluid Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper devices for vehicles lack a efficient and uniform method for dispensing fluid along the wiper blade to ensure thorough window cleaning, often resulting in incomplete cleaning due to uneven fluid distribution.
Innovation Solution
A wiper device design featuring a nozzle base body that is removably and tool-free fixed to the wiper blade, forming part of the end cap and spoiler, with a fluid connection system allowing for controlled fluid dispensing, ensuring even distribution and dual functionality as both a fluid dispenser and end cap, eliminating the need for separate fastening elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate fastening elements are used to attach the nozzle body to the wiper blade, then the nozzle body can be securely fixed, but the device complexity increases and assembly becomes more cumbersome
Solution Approach 1:
The nozzle body is integrally formed with the end cap of the wiper blade, combining two separate components (nozzle body and end cap) into a single unit. This eliminates the need for separate fastening elements while maintaining secure fixation, as the nozzle body becomes an inherent part of the wiper blade structure.
Solution Approach 2:
The end cap serves dual functions: it closes the end of the wiper blade structure and houses the nozzle body for fluid dispensing. This multi-functional design integrates fastening and fluid dispensing capabilities into a single component, reducing overall device complexity.
2Ease of manufacture
If multiple separate components are used for the nozzle unit, then each component can be optimized independently, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The nozzle body and end cap are manufactured as a single integral component, eliminating the assembly step between these two parts. This reduces assembly time and potential assembly errors while maintaining the ability to optimize the entire nozzle assembly design in the manufacturing process.
3Stability of the object's composition
If the nozzle body is permanently fixed to the wiper blade, then the structure is more stable, but repair and replacement become more difficult
Solution Approach 1:
The nozzle assembly is designed as a detachable unit that can be separated from the wiper blade when needed. This segmentation allows the nozzle body to be firmly attached during operation for stability, while enabling easy removal and replacement for maintenance or upgrades without permanent fixation.
