Solution Overview

Problem

Existing vehicle washing apparatuses are ineffective in cleaning the underbody of vehicles and distribute wash liquid in a non-homogeneous manner due to the arrangement of washing nozzles, leading to incomplete cleaning.

Innovation Solution

The apparatus features additional washing nozzles in the side walls that can oscillate, allowing for precise cleaning of the underbody and side walls, with high-pressure and low-pressure wash liquid distribution capabilities, and a control system to manage nozzle activation for optimal cleaning sequences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If washing nozzles are arranged in the side walls of the containment structure, then the vehicle can be washed automatically, but the below part of the vehicle or underbody cannot be washed effectively

Engineering Contradiction:
Improveautomatic washingVSAvoidwashing coverage precision
Core Design Contradiction:
Extent of automationVSManufacturing precision

Solution Approach 1:

The washing system is segmented into multiple independent nozzle groups: fixed nozzles for general washing, movable nozzles for underbody cleaning, and oscillating nozzles for side wall treatment. Each segment performs a specific washing function, collectively achieving complete vehicle coverage while maintaining automatic operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces movable and oscillating nozzle components that can dynamically adjust their positions and orientations. The movable nozzles translate along guides to reach the underbody, while oscillating nozzles sweep across side walls, transforming the static washing system into a dynamic one capable of adapting to different vehicle surfaces.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If washing nozzles discharge jets of wash liquid along rectilinear trajectories, then the washing process is simple, but the wash liquid is distributed in a non-homogenous manner over the vehicle surface

Engineering Contradiction:
Improvenozzle discharge mechanismVSAvoidwash liquid distribution uniformity
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The oscillating nozzles perform periodic back-and-forth movements, delivering wash liquid in rhythmic pulses across the side walls. This periodic action transforms the rectilinear jet into a sweeping coverage pattern, ensuring homogeneous distribution while maintaining relatively simple nozzle mechanics.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

By making the nozzles oscillate rather than fixed, the system dynamically redistributes the wash liquid across different zones. The oscillating motion converts a single-direction rectilinear jet into a multi-directional coverage pattern, achieving uniform distribution without complex multi-nozzle arrays.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If additional washing nozzles and movement means are added to clean the underbody and side walls, then washing precision is improved, but device complexity increases

Engineering Contradiction:
Improvewashing coverage precisionVSAvoidnozzle arrangement complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The complex washing task is divided into manageable segments handled by different nozzle types: fixed nozzles for accessible areas, movable nozzles on guides for underbody regions, and oscillating nozzles for side walls. This segmentation allows each component to be relatively simple while the system as a whole achieves comprehensive precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The movable and oscillating nozzle mechanisms serve multiple functions: they can clean different vehicle surfaces (underbody, side walls, panels), adjust to different positions, and work in coordination with fixed nozzles. This multi-functionality reduces the need for entirely separate systems for each washing zone, moderating the overall complexity increase.

Inventive Principle:
Principle #6Universality (Multi-functionality)
