Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional blasting methods are used to remove carbon deposits, then cleaning effectiveness is improved, but surface abrasion and damage to valve and inlet duct surfaces occur
Solution Approach 1:
The invention changes the physical and chemical parameters of the cleaning medium by using water-soluble cleaning powder that dissolves upon contact with moisture from the carbon deposits, transforming from a purely mechanical blasting process to a combined chemical-mechanical cleaning process that reduces surface abrasion
Solution Approach 2:
The invention introduces water-soluble cleaning powder as an intermediary substance that mediates between the blasting medium and the surface. The powder dissolves in moisture from the carbon deposits to form a cleaning solution that chemically breaks down deposits while being gentler on metal surfaces than conventional abrasive blasting
2Object-affected harmful factors
If chemical cleaning agents are used to dissolve carbon deposits, then surface gentleness is improved, but cleaning effectiveness on heavy contamination decreases
Solution Approach 1:
The invention merges mechanical blasting action with chemical cleaning by using water-soluble cleaning powder that provides both mechanical impact during powder delivery and chemical dissolution when it contacts moisture, creating a combined cleaning mechanism that overcomes the limitations of using either method alone
3Productivity
If abrasive blasting is used to remove deposits, then cleaning speed is improved, but material removal from valve surfaces increases
Solution Approach 1:
The invention partially replaces the purely mechanical blasting system with a chemical cleaning mechanism. The water-soluble cleaning powder dissolves carbon deposits through chemical reaction when it contacts moisture, reducing the reliance on high-velocity mechanical impact and thereby reducing material removal while maintaining cleaning speed
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 method achieves 100% dirt removal with minimal material abrasion, ensuring the valve and inlet duct surfaces are cleaned effectively, preventing engine damage and reducing the need for costly replacements.
Implementation Method 1
a water-soluble cleaning powder jet is introduced into a cavity to be cleaned by means of a compressed gas, and that at the same time an aqueous liquid is introduced into the cavity to be cleaned, so that a cleaning liquid is introduced into the cavity to be cleaned by dissolving the cleaning powder in the aqueous liquid
Implementation Method 2
a water-soluble cleaning powder jet is introduced into a cavity to be cleaned by means of a compressed gas
Implementation Method 3
the cleaning liquid and the introduced gas is sucked with the dirt components dispersed therein from the cavity

AI summary
A water-soluble cleaning powder (44) is introduced as a powder jet into the to-be-cleaned cavity, through a compressed gas, while introducing an aqueous liquid (48) into the to-be-cleaned cavity, so that, when the cleaning powder is released into the aqueous liquid, a cleaning fluid is formed in the cavity. By the suction effect of cleaning fluid with the introduced gas, the dirt particles are dispersed out of the cavity along with the cleaning fluid. The amounts of cleaning powder and aqueous liquid are matched, so that the cleaning powder is completely released in aqueous liquid. An independent claim is included for a device for cleaning coked cavities of valves in intake ports of combustion engine.
