Remote-Controlled Gasoline Cleaner Engine Start-Stop Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gasoline cleaners cannot be remotely controlled, are inconvenient to start and shut down, and waste energy and produce pollution during standby mode.
Innovation Solution
A remote-controlled gasoline cleaner with a main unit and sprayer, featuring a remote control that sends start and stop signals to a controller, which controls a start switch device to initiate the gasoline engine and a stop switch device to shut it down, including an automatic reset blow-out switch and wireless communication modules for long-distance operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing gasoline cleaners operate in standby mode to maintain engine operation, then the engine remains ready for immediate use, but energy is wasted, noise is generated, and exhaust pollution is produced
Solution Approach 1:
The system performs preliminary action by pre-heating the engine and maintaining it in a warm-ready state through the control unit before actual cleaning operations begin. This allows the engine to be ready for immediate use without continuous standby operation, reducing energy waste while maintaining reliability.
Solution Approach 2:
The control unit implements periodic action by cycling the engine operation - running it only when cleaning operations are needed and shutting it down during non-use periods. This periodic operation maintains engine readiness through controlled cycles rather than continuous standby, significantly reducing energy consumption and pollution.
2Device complexity
If existing gasoline cleaners require manual operation for start and shutdown, then the structure remains simple, but the ease of operation deteriorates when the cleaner is located at a distance
Solution Approach 1:
The control unit serves as an intermediary between the user and the engine system. It receives signals from the controller (which can be remotely operated) and executes the appropriate engine start/stop commands, thereby improving ease of remote operation while maintaining relatively simple overall device structure through modular design.
Solution Approach 2:
The patent replaces manual mechanical operation with an electronic control system. The controller and control unit use electrical signals to initiate and terminate engine operation, eliminating the need for manual mechanical intervention and enabling remote operation while keeping the mechanical structure of the engine itself unchanged.
3Device complexity
If existing gasoline cleaners cannot be remotely controlled, then the control system remains simple, but the ease of operation worsens when users need to reach the main unit from a distance
Solution Approach 1:
The control unit acts as an intermediary that receives remote signals from the controller and translates them into engine control commands. This intermediary layer enables remote control functionality without requiring complex direct communication systems, maintaining relative simplicity while achieving the desired ease of remote operation.
Solution Approach 2:
The control unit is designed with multi-functionality, serving both as a local control interface and as a remote signal receiver. This universal design allows the same component to handle both near-field manual operation and far-field remote operation, improving ease of operation across different usage scenarios without proportionally increasing device complexity.

AI summary
A remote-controlled gasoline cleaner including a main unit, sprayer, and remote control. The main unit includes a controller, start switch device, stop switch device, and gasoline engine start/stop apparatus. The remote control sends a start remote control signal or stop remote control signal to the main unit. The controller controls the start switch device in response to the start remote control signal received, and controls the stop switch device in response to the stop remote control signal received. The start switch device receives a start command of the controller to connect to a power supply circuit of a starter motor in the gasoline engine start/stop apparatus. The starter motor starts a gasoline engine. The stop switch device receives a stop command of the controller to connect to a short circuit of an ignition coil in the gasoline engine start/stop apparatus, thereby blowing out the gasoline engine.
