Vehicular Washer Nozzle Mounting Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle washer nozzle device mounting structures compromise the external appearance of vehicles by being visible when the front hood is opened and limit driver visibility due to their placement and design, which also restricts the lowering of the front hood to accommodate maintenance and various vehicle types.
Innovation Solution
A vehicle washer nozzle device mounting structure where the nozzle is positioned between the upper surface of the front hood and the lower surface of the hood garnish, with a hood garnish extending along the rear end of the front hood, and a tubular cover integrated with the nozzle to adjust injection angles and conceal the nozzle from external view, allowing for a unified appearance across different vehicle types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the washer nozzle device is mounted to the cowl top panel, then the nozzle can be positioned to spray the panel surface, but the device becomes visible when the front hood is opened, deteriorating the external appearance
Solution Approach 1:
The washer nozzle device is nested within the hood garnish structure, specifically positioned in a recessed area formed by the garnish. The garnish acts as a housing that contains the nozzle device, making it invisible from the exterior when the hood is open, while still allowing the nozzle to function properly for spraying the windshield.
Solution Approach 2:
The hood garnish serves as an intermediary element between the washer nozzle device and the exterior environment. It provides a mounting structure that conceals the nozzle device while allowing it to perform its spraying function, thus mediating between the need for visibility concealment and functional operation.
2Ease of operation
If the washer nozzle device is disposed in the space between the front hood and cowl top panel, then maintenance inspections can be easily carried out, but the device remains visible from outside, interfering with external appearance
Solution Approach 1:
The washer nozzle device is nested within the hood garnish structure, which is positioned in the space between the front hood and cowl top panel. This nesting arrangement maintains the accessibility benefits of the space while adding the concealment function of the garnish housing.
3Adaptability or versatility
If the washer nozzle device is mounted to accommodate various vehicle types with different facing wall inclinations, then the device can be universally applied, but displacement on the rear end surface becomes noticeable, interfering with external appearance
Solution Approach 1:
The hood garnish is designed as a universal mounting structure that can accommodate washer nozzle devices on various vehicle types with different facing wall inclinations. The garnish provides a standardized recessed mounting area that maintains consistent external appearance across different vehicle configurations, eliminating the need to adjust the nozzle device position for each vehicle type.

AI summary
A washer nozzle device for spraying a washer fluid onto a front window panel is mounted to a vehicle body. The vehicle body includes a front hood disposed in front of the front window panel, and a hood garnish disposed on the front hood. The hood garnish is disposed over an upper surface of the front hood at an interval and extended along a rear end of the front hood in a vehicle width direction. The washer nozzle device is positioned between the upper surface of the front hood and a lower surface of the hood garnish.
