Solution Overview
Problem
Existing vacuum degreasing and cleaning apparatuses face challenges such as inefficient solvent use, complex loading processes for complex-shaped objects, solvent condensation issues, and regulatory complexities due to the need for large solvent volumes and hazardous material handling.
Innovation Solution
A vacuum degreasing and cleaning apparatus with a cleaning chamber, injector, sprayer, storage tanks, and a distiller that vaporizes solvent using a heating means within the sprayer, allowing efficient solvent introduction and recycling, and featuring multiple injectors for varied pressure cleaning methods, along with smaller storage tank capacities to reduce solvent usage and regulatory burdens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a plurality of cleaning nozzles are used to clean complex-shaped objects, then cleaning coverage is improved, but loading process complexity increases
Solution Approach 1:
The cleaning nozzles are made movable rather than fixed, allowing them to be repositioned according to the shape and size of different objects. This dynamic positioning capability enables the same apparatus to handle various object configurations without requiring complex pre-planned loading arrangements, thus maintaining cleaning uniformity while simplifying the loading process.
Solution Approach 2:
The cleaning system is divided into multiple independent nozzles that can operate separately and be positioned independently. This segmentation allows each nozzle to be optimally positioned for different parts of complex-shaped objects, achieving comprehensive cleaning coverage without requiring a complex fixed loading structure.
2Loss of substance
If solvent is introduced by sprayer and vaporized, then solvent usage efficiency is improved, but solvent introduction efficiency decreases due to condensation in piping
Solution Approach 1:
The system changes the temperature parameter of the solvent from ambient to elevated temperature before introduction. By heating the solvent to a higher temperature, the patent prevents condensation during transport through the piping system, thereby maintaining solvent introduction efficiency while still achieving efficient cleaning and vaporization at the target.
Solution Approach 2:
The solvent is pre-heated before being introduced into the cleaning chamber, rather than relying on in-transit vaporization. This preliminary heating action ensures the solvent remains in vapor phase throughout the piping system, preventing condensation losses and ensuring efficient delivery to the cleaning zone.
3Reliability
If large volume of solvent is used for cleaning, then cleaning effectiveness is improved, but environmental impact and regulatory burden increase
Solution Approach 1:
The system utilizes phase transition of the solvent from liquid to vapor and back to liquid for efficient cleaning with minimal solvent volume. The solvent is vaporized for cleaning, then condensed and recovered, allowing the same small amount of solvent to be reused multiple times, thereby maintaining cleaning effectiveness while dramatically reducing environmental impact and regulatory burden.
Solution Approach 2:
Instead of discarding used solvent, the system recovers it through condensation and returns it to the storage tank for reuse. This recovery process eliminates the need for large continuous solvent supplies, reducing both environmental impact and regulatory requirements while maintaining consistent cleaning effectiveness.
