Vehicle Washer Nozzle with Multi-Step Locking and Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional non-exposing type washer nozzles for vehicles are fixed in a predetermined angle and direction, unable to adjust the spraying direction or target position, and lack a heating unit, making them ineffective in low-temperature conditions.
Innovation Solution
A washer nozzle with a multi-step locking portion for adjustable angle adjustment and a heating assembly that includes a heating body, thermal conductor, and thermal conductive filler to heat the washer fluid, allowing for flexible spraying direction and position adjustment and improved heating performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the washer nozzle is fixed within the aperture by tension of locking step, then the installation is simple and compact, but the spraying direction and target position cannot be adjusted
Solution Approach 1:
The washer nozzle is designed with a rotatable structure that allows it to change its spraying direction dynamically. The nozzle body can rotate relative to the housing around a rotation axis, enabling adjustment of the spraying angle while maintaining the compact non-exposing installation structure. This dynamic capability resolves the contradiction by adding adjustability without requiring a completely different mounting system.
2Adaptability or versatility
If the washer nozzle is disposed in hood interior panel without protruding, then the external appearance is not altered, but the nozzle angle cannot be adjusted
Solution Approach 1:
The washer nozzle system is divided into separable components: a housing that mounts to the hood interior panel, and a nozzle body that can rotate independently within the housing. The locking mechanism is segmented into multiple locking steps that correspond to different spraying directions. This segmentation allows the nozzle to maintain a fixed compact installation while enabling angle adjustment through rotation and locking at different positions.
Solution Approach 2:
The nozzle body is designed to rotate dynamically within the housing around a rotation axis, allowing adjustment of the spraying direction. The rotation capability is combined with a locking mechanism that can secure the nozzle at multiple angular positions, providing adaptability while maintaining the non-exposing compact installation structure.
3Reliability
If the washer nozzle lacks heating unit, then the structure is simple, but washer fluid at low temperature cannot reach desired target point
Solution Approach 1:
A heating element is integrated into the housing to change the temperature parameter of the washer fluid before it reaches the nozzle. The heating element can be electrically activated to warm the washer fluid, ensuring that even in low-temperature environments, the fluid remains liquid and can be effectively sprayed onto the windshield, thereby improving reliability in cold conditions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables adjustable spraying direction and position, ensuring effective cleaning in various conditions, including low temperatures, by allowing users to freely adjust the nozzle angle and heating the washer fluid for improved performance.
Implementation Method 1
a heating body disposed in an insertion space defined at a lower part of the nozzle portion in the housing and configured to generate heat when power is supplied via a wire
Implementation Method 2
A thermal conductor may be disposed at an interval between the heating body and the nozzle portion

AI summary
A washer nozzle for a vehicle is provided. The washer nozzle includes a multi-step locking portion having a plurality of projections formed on the top of the housing and a fixing groove where a lower interior-side end of a mounting aperture formed at a vehicle body is inserted is formed on the bottom of the housing. The washer nozzle is inserted in the mounting aperture and the washer nozzle is configured to rotate to adjust an angle about the fixing groove in which the lower interior-side end of the mounting aperture is inserted. Further, one selected projection of the multi-step locking portion is configured to be locked to a portion of the vehicle body to maintain the adjusted angle of the washer nozzle.
