Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic car washing devices suffer from poor cleaning effectiveness due to insufficient spray pressure from sprinklers, unnecessary water waste, and inability to target specific car positions, leading to increased costs and resource inefficiency.
Innovation Solution
An automatic car washing device with independently controlled water sprayers and shampoo sprayers, allowing selective activation based on car washing instructions, and a hub cleaning structure with intelligent identification for targeted cleaning, reducing the number of open sprayers to achieve high-pressure cleaning and minimize costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If all sprinklers are opened simultaneously to clean different positions of the car, then the cleaning coverage is improved, but the spray pressure of each sprinkler decreases and cleaning effectiveness deteriorates
Solution Approach 1:
The water delivery system is segmented into multiple independent water pipes, each serving specific sprinklers. This allows selective activation of individual water pipes and their corresponding sprinklers based on the cleaning position, ensuring that only the necessary sprinklers are activated at any given time. This segmentation maintains high spray pressure while providing adequate cleaning coverage.
Solution Approach 2:
The system dynamically activates or deactivates specific water pipes and sprinklers based on the real-time cleaning position and requirements. The control system adjusts which sprinklers are active during different phases of the car washing process, optimizing both pressure and coverage dynamically rather than having all sprinklers operate simultaneously.
2Stress or pressure
If the booster pump pressure is increased to achieve high spray pressure for effective cleaning, then the cleaning effectiveness is improved, but the device cost increases
Solution Approach 1:
By segmenting the water delivery system into multiple independent pipes with individual control valves, the system can deliver high pressure to specific sprinklers on demand rather than requiring the entire system to operate at high pressure simultaneously. This allows using a moderate-pressure pump while achieving high-pressure spray at the nozzle through controlled delivery.
Solution Approach 2:
The system changes the operational parameters by controlling which sprinklers are active at different times and positions. Instead of maintaining high pressure across all sprinklers continuously, the system adjusts pressure delivery dynamically to match the actual cleaning needs, reducing overall energy consumption and pump requirements while maintaining effective cleaning pressure where needed.
3Area of stationary object
If all sprinklers are opened simultaneously to ensure complete cleaning coverage, then the cleaning coverage is improved, but water resource waste increases
Solution Approach 1:
The water delivery system is divided into multiple independently controllable water pipes, each serving specific cleaning zones. This segmentation enables precise control over water delivery, activating only the water pipes and sprinklers corresponding to the current cleaning position, thereby eliminating water waste to areas that do not require cleaning at that moment while maintaining complete coverage.
Solution Approach 2:
The system employs periodic activation of different water pipes and sprinkler groups based on the cleaning sequence. Different sets of sprinklers are activated in different time periods corresponding to different cleaning positions, ensuring that water is delivered only when and where needed, reducing overall water consumption while maintaining comprehensive cleaning coverage.
4Ease of operation
If the system can only open or close all sprinklers simultaneously, then the control simplicity is maintained, but the ability to clean specific positions deteriorates
Solution Approach 1:
The water delivery system is segmented into multiple independently controlled water pipes, each manageable by individual control valves. This segmentation allows the control system to activate specific water pipes and their corresponding sprinklers for targeted cleaning of particular car positions, while maintaining relatively simple control logic through automated position-based activation sequences.

AI summary
An automatic car washing apparatus, comprising a guide rail apparatus and a washing frame (5) arranged on the guide rail apparatus. The washing frame (5) is provided with a plurality of independently controlled water spraying apparatuses that are disposed at different positions and a plurality of independently controlled car washing shampoo spraying apparatuses (11); the water spraying apparatuses (11) are all connected to a single water pipe by means of corresponding switch assemblies; and one end of the single water pipe is connected to a water pump. A car washing instruction is obtained; and the washing frame is moved to corresponding washing positions on the basis of the car washing instruction, and, on the basis of the car washing instruction, corresponding water spraying apparatuses and/or car washing shampoo spraying apparatuses are sequentially started to operate for set washing durations, water spraying apparatuses and/or car washing shampoo spraying apparatuses that are not started being in an off state. The automatic car washing apparatus solves the problem of nonideal washing effect due to water spraying nozzles on existing automatic car washing apparatuses being unable to generate enough spraying pressure, improves the diversity of car washing modes, and greatly reduces the car washing cost. Also provided is an automatic car washing method.
