Solution Overview
Problem
Existing chemical dispensing systems for laundry and warewashing require custom applications for different types of washing systems and are difficult to retrofit, lacking adaptability to varying numbers of machines and incompatible chemical separation.
Innovation Solution
A modular chemical dispensing system with a microprocessor-controlled main controller and plug-and-play satellite pumps, allowing easy conversion between laundry and warewashing systems by replacing an integrated circuit chip, and enabling expansion with additional peripheral units for multiple chemical delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual dispensers are used for each machine, then chemical delivery is simple and reliable, but cost and environmental efficiency deteriorate due to lack of consolidation
Solution Approach 1:
The patent consolidates multiple individual chemical dispensing functions into a single centralized dispensing system that can serve multiple washing machines. The system uses a common chemical supply source and distribution network to deliver chemicals to multiple machines, replacing the need for separate dispensers at each machine while maintaining reliable chemical delivery.
2Productivity
If concentrated chemicals are mixed with diluent on-demand, then chemical usage efficiency is improved, but system complexity increases due to mixing control requirements
Solution Approach 1:
The system separates the chemical delivery function into distinct segments: a centralized mixing station that prepares diluted chemical solutions, and distribution points at each washing machine. The mixing process is controlled centrally, while the distribution to multiple machines is managed through separate delivery lines, allowing independent optimization of each function.
Solution Approach 2:
The patent introduces an intermediary diluted chemical solution as a medium between the concentrated chemical source and the washing machines. The centralized mixing system acts as an intermediary that converts concentrated chemicals into ready-to-use diluted solutions, which are then distributed to multiple machines through a network of delivery lines.
3Reliability
If use dilutions are segregated with flush diluent, then chemical compatibility is maintained, but water consumption and system complexity increase
Solution Approach 1:
The system implements periodic flushing cycles where diluent is used to clear the delivery lines between different chemical deliveries. The microprocessor controller manages periodic flush operations that temporarily interrupt chemical delivery to perform line clearing, ensuring chemical compatibility while minimizing the amount of flush diluent required through optimized timing and duration.
4Productivity
If custom applications are designed for different washing systems, then system performance is optimized, but adaptability to different configurations deteriorates
Solution Approach 1:
The patent designs a universal dispensing system with a standardized interface and microprocessor-controlled architecture that can adapt to different washing machine configurations. The system uses programmable delivery parameters and adjustable mixing ratios to optimize performance for various machine types without requiring custom hardware designs, allowing a single system design to serve multiple applications.

AI summary
A modular chemical delivery system is designed to be readily convertible from use with a warewashing system to use with a laundry system, or vice-versa, merely by the replacement of one chip in the controller of the system. The dispensing system is also readily expandable by adding additional satellite pumps in order to inject additional chemicals into a single washing unit, and/or to supply chemicals to additional washing units. Plug and play technology is used so that control intelligence can be distributed from the main system controller to satellite controllers, and so that additional satellite units may be readily added, identified, and properly integrated into the dispensing system.
