Condition warning system, control system and method for pot and pan washing machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control systems for continuous motion pot and pan washing machines require frequent draining and refilling, limit wash cycle flexibility, and lack efficient warning mechanisms, leading to inefficiencies and resource waste, especially when dealing with heavily soiled items or near-end-of-cycle washing needs.
Innovation Solution
A microprocessor-based control system that includes punitive wash action lockout, extended wash cycle, and deep clean cycle features, allowing for temporary lockout of the wash pump to enforce operational compliance without full tank drainage, providing advanced warning systems and flexible wash modes to enhance cleaning efficiency and operator convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wash pump is locked out to enforce operational compliance, then compliance with operational conditions is ensured, but wash cycle continuity is interrupted
Solution Approach 1:
The control system performs preliminary monitoring of operational conditions (fluid temperature, fluid level, chemical concentration) and implements punitive lockout before serious failures occur. This ensures compliance by preemptively stopping the wash pump when parameters deviate from acceptable ranges, preventing equipment damage or unsafe conditions while maintaining wash cycle integrity through automatic reset capability
Solution Approach 2:
The control system continuously monitors operational parameters and provides feedback to the wash pump operation. When conditions meet punitive lockout criteria, the system activates the lockout and illuminates a light to alert the operator. The system maintains feedback by monitoring when conditions no longer meet lockout criteria, enabling automatic restoration of wash pump operation and ensuring continuous compliance
2Reliability
If the wash tank is drained and refilled before predetermined run-time expires, then cleaning efficiency is maintained, but productivity is reduced
Solution Approach 1:
The control system provides preliminary warning by illuminating a light when operational conditions approach punitive lockout thresholds, giving operators advance notice to prepare for potential tank drainage or refill operations. This allows planning and minimization of productivity impact while maintaining cleaning efficiency through proactive rather than reactive management
Solution Approach 2:
The system dynamically adjusts operational parameters within acceptable ranges to extend wash cycle duration. By monitoring fluid temperature, fluid level, and chemical concentration, the control system optimizes the wash cycle to maintain cleaning efficiency for as long as possible, delaying the need for tank drainage and maximizing productivity
3Productivity
If the wash pump operates continuously for extended periods, then productivity is improved, but operational compliance may be compromised
Solution Approach 1:
The control system implements continuous feedback monitoring of operational parameters including fluid temperature, fluid level, and chemical concentration. This feedback mechanism ensures operational compliance by detecting when parameters deviate from acceptable ranges and automatically activating punitive lockout to stop the wash pump, preventing equipment damage or unsafe conditions even during extended operation
Solution Approach 2:
The system performs preliminary monitoring and provides warning illumination before operational compliance is violated, allowing for corrective action to be taken while the wash pump is still operating. This maintains productivity by enabling smooth transitions to lockout state without sudden interruptions, while ensuring compliance through proactive parameter management
