Portable Under-Sprayer Control and Spray Mat for Safer Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing under-sprayers for vehicles are large, non-portable, and ineffective in cleaning the underside of vehicles without requiring the driver to exit the vehicle, risking spray exposure, and lacking tactile feedback for complete cleaning.
Innovation Solution
A portable under-sprayer system that includes a control panel, high-pressure line, and spray mat assembly, allowing for easy operation from within the vehicle, eliminating driver exposure to spray, and providing tactile feedback for complete cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional under-sprayer systems are used, then cleaning effectiveness is achieved, but portability and ease of operation deteriorate due to large volume and complex setup
Solution Approach 1:
The system is divided into separate components: a portable control unit that fits in the vehicle, a collapsible hose, and a spray wand. This segmentation allows each component to be compact and easily stored within the vehicle while maintaining full cleaning functionality when deployed.
Solution Approach 2:
The spray wand and nozzle assembly can be collapsed or nested within the hose when not in use, and the entire system can be stored in a compact configuration within the vehicle's interior space, reducing the volume occupied during storage and transport.
2Ease of operation
If driver exits vehicle to operate traditional sprayers, then direct control is achieved, but safety deteriorates due to spray exposure and cold temperatures
Solution Approach 1:
A wireless remote control or electronic switch acts as an intermediary between the driver and the spray system, allowing the driver to operate the sprayer from inside the vehicle without direct exposure to cold temperatures and spray mist.
Solution Approach 2:
The system incorporates sensors that detect when the undercarriage has been adequately cleaned and provide feedback to the driver through visual or audible signals, eliminating the need for the driver to exit the vehicle to verify cleaning completion.
3Productivity
If high pressure spray is used for effective cleaning, then cleaning effectiveness is improved, but harmful factors increase due to driver exposure to spray
Solution Approach 1:
The system uses a directed spray nozzle with a long reach that allows the driver to clean the undercarriage from a safe distance, maintaining high cleaning effectiveness while minimizing exposure to the spray mist.
Solution Approach 2:
The spray generation and delivery system is extracted from the vehicle interior and positioned externally, allowing the high-pressure spray to be generated and directed away from the driver's position while maintaining effective cleaning capability.
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
The system effectively removes salt, mud, and other buildup from vehicle undercarriages at the press of a button, enhancing portability, safety, and cleaning efficiency.
Implementation Method 1
high pressure line into the control panel outlet port. This line connects to the Spray Mats
Implementation Method 2
control panel, a pressure line and a spray mat assembly

AI summary
The invention is an Undersprayer for automotive enthusiasts and people who like to keep their vehicle clean. It can also be used by off-road enthusiasts to clear mud off the bottom of off-road vehicles. The system requires that the end-user have a power washer and an air compressor. The device has a control panel, an upright frame, a motor and pump system, a pressure line and a spray mat assembly. With the supplied adapters the user plugs in the power washer and air compressor into the control panel. The user then plugs in the supplied high pressure line into the control panel outlet port. This line connects to the spray mat that lays in the driveway.
