Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing apparatuses face challenges in efficiently cleaning protective equipment, including difficulty in handling coarse particles, long startup times, and fluctuating fluid temperatures during wash cycles.
Innovation Solution
The method involves pumping fluid at an operating pressure to wash protective equipment and at a lower circulation pressure through a circulation loop back to the tank, ensuring fluid properties are homogenized, and the washing apparatus is maintained at a consistent temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fluid is pumped continuously at high operating pressure to wash protective equipment, then washing efficiency is improved, but fluid temperature fluctuates and startup time increases
Solution Approach 1:
The system performs preliminary homogenization of fluid temperature and properties during idle periods before the wash cycle begins. The circulation pump operates during idle time to pre-condition the fluid, ensuring stable temperature and uniform properties are established before high-pressure washing starts, thereby reducing startup time and temperature fluctuations during operation.
Solution Approach 2:
The system uses periodic alternation between circulation mode (at circulation pressure) and washing mode (at operating pressure). During idle periods, the pump operates at circulation pressure to homogenize fluid properties; during wash cycles, it switches to operating pressure for washing. This periodic switching optimizes both temperature stability and washing efficiency without continuous high-pressure operation.
2Stability of the object's composition
If fluid circulation is increased to homogenize fluid properties, then temperature uniformity is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts pump pressure between two distinct levels: circulation pressure (lower) for homogenization during idle periods, and operating pressure (higher) for washing during active cycles. This dynamic pressure adjustment ensures adequate fluid property uniformity while minimizing energy consumption by using lower pressure when washing is not occurring.
Solution Approach 2:
The system changes the pressure parameter of the pump based on operational state. During idle periods, pressure is reduced to circulation pressure for efficient homogenization; during wash cycles, pressure is increased to operating pressure for effective washing. This parameter change optimizes the balance between fluid uniformity and energy consumption.
3Manufacturing precision
If particles are removed from protective equipment during washing, then cleaning quality is improved, but washing apparatus functionality deteriorates due to particle buildup
Solution Approach 1:
The system performs preliminary high-pressure flushing at the beginning of wash cycles to clear accumulated particles from the washing chamber and fluid paths before the main washing process. This preliminary action prevents particle buildup from interfering with washing quality while maintaining apparatus functionality throughout the cycle.
Solution Approach 2:
The system maintains continuous particle removal through the circulation system during idle periods between wash cycles. The circulation pump continuously moves fluid through the system, preventing particle settlement and buildup, thereby maintaining apparatus reliability and readiness for the next wash cycle without interrupting the useful washing function.
