Rotatable Nozzle for Vehicle Cleaner Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cleaner systems face challenges in adjusting the injection direction of cleaning media effectively across different vehicle types due to varying mounting conditions, leading to potential assembly variations and increased manufacturing and operational costs.
Innovation Solution
A vehicle cleaner system featuring a rotatable nozzle held by a nozzle holder, where the nozzle is press-fitted and its rotational direction is restricted to a predetermined axis, allowing for easy adjustment of the injection direction without requiring shape changes based on vehicle type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the nozzle shape is changed to accommodate different vehicle types, then the cleaning effectiveness is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The nozzle is designed to be rotatable relative to the nozzle holder, allowing dynamic adjustment of the injection direction. This enables a single nozzle design to adapt to different vehicle types and mounting positions without requiring multiple specialized nozzle shapes, thereby maintaining cleaning effectiveness while reducing device complexity and manufacturing costs.
2Manufacturing precision
If the nozzle is fixed in position, then the manufacturing precision is improved, but the adaptability to different vehicle types deteriorates
Solution Approach 1:
The nozzle is designed with rotational capability relative to the nozzle holder through a press-fit connection. This dynamic feature allows the same precisely manufactured nozzle to be adapted to different vehicle types and mounting positions by simply rotating it to the appropriate angle, eliminating the need to manufacture different nozzle shapes for different applications.
3Adaptability or versatility
If the nozzle is made adjustable, then the adaptability to different vehicle types is improved, but the ease of operation deteriorates due to assembly variations
Solution Approach 1:
The nozzle is designed to be rotatable relative to the nozzle holder, allowing easy adjustment of the injection direction. The press-fit connection enables simple rotational adjustment without complex assembly procedures, maintaining ease of operation while providing adaptability to different vehicle types and mounting conditions.
