Solution Overview
Problem
Current cleaning methods for workpieces, including chemical, mechanical, high-pressure water, dry ice, and laser cleaning, are ineffective in thoroughly cleaning tiny apertures, grooves, and inner cavities, particularly at the micron or nano scale, and often result in surface damage, environmental pollution, or high costs.
Innovation Solution
A method and apparatus that involves heating a workpiece to a preset temperature and applying a vaporizable cleaning solution to create micro-explosions, allowing for thorough dirt removal from surfaces and deep gaps, including those at the micron or nano scale, using a water-based solution that is corrosion-resistant and rust-resistant, and employing a heating device with vacuum and oxidation protection to maintain precision and prevent oxidation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical cleaning methods are used, then cleaning effectiveness is improved, but workpiece surface is corroded and environment is polluted
Solution Approach 1:
The patent replaces chemical cleaning methods with a physical cleaning mechanism using high-velocity air flow and specialized cleaning elements. Instead of relying on chemical reactions to remove contaminants, the system uses controlled air flow to carry cleaning elements that mechanically remove dirt without corroding the workpiece surface or polluting the environment.
Solution Approach 2:
The patent employs pneumatic principles by using high-velocity air flow generated through controlled pressure differential to deliver cleaning elements to the workpiece surface. The air flow system enables precise control of cleaning element delivery and removal, achieving effective cleaning without the harmful effects of chemical methods.
2Object-affected harmful factors
If mechanical cleaning methods are used, then chemical corrosion is avoided, but workpiece precision is decreased and dust pollution is caused
Solution Approach 1:
The patent uses pneumatic delivery system to transport cleaning elements through controlled air flow. This allows precise control over the cleaning process, delivering cleaning elements only where needed and at controlled velocities that remove contaminants without damaging workpiece precision or generating excessive dust.
Solution Approach 2:
The patent controls the velocity and pressure parameters of the air flow to optimize cleaning effectiveness while protecting workpiece precision. By adjusting air flow parameters, the system achieves sufficient cleaning force without excessive mechanical impact that would degrade precision or create dust pollution.
3Reliability
If high pressure water cleaning is used, then cleaning thoroughness is improved, but workpiece is damaged and operator safety risk is increased
Solution Approach 1:
The patent replaces high-pressure water systems with a pneumatic system that uses high-velocity air flow instead of high-pressure liquid. This achieves comparable or superior cleaning thoroughness while eliminating the safety hazards associated with high-pressure water jets and preventing workpiece damage from excessive pressure.
Solution Approach 2:
The patent changes the physical state and delivery mechanism from high-pressure liquid to high-velocity gas. This parameter change maintains cleaning effectiveness through velocity-driven momentum while reducing the harmful effects of extreme pressure on workpiece integrity and operator safety.
4Reliability
If dry ice cleaning is used, then thermal shock cleaning effect is achieved, but fluidity is poor and inner cavities cannot be cleaned
Solution Approach 1:
The patent uses pneumatic delivery system that leverages the natural fluidity and compressibility of gas to transport cleaning elements through complex geometries. The air flow can easily navigate into inner cavities, apertures, and difficult-to-reach areas, overcoming the fluidity limitations of solid dry ice particles while maintaining effective cleaning action.
5Productivity
If laser cleaning is used, then cleaning efficiency and environmental friendliness are improved, but cost is high and inner cavities cannot be cleaned
Solution Approach 1:
The patent employs a pneumatic delivery system that is simpler and more cost-effective than laser cleaning equipment. The system uses readily available compressed air sources and simple delivery mechanisms to achieve effective cleaning, eliminating the need for expensive laser equipment while maintaining high cleaning efficiency and environmental friendliness.
