Cast Solid Dispenser Control for Consistent Dissolution Chemistry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The dissolution of cast solid products for obtaining cleaning and sanitizing solutions is affected by variations in inputs and operating parameters, leading to inconsistent chemistry and efficiency, and existing dispensers struggle to control these parameters independently of the operating environment.
Innovation Solution
A dispenser system that maintains a constant distance between a nozzle and the solid product during dissolution, adjusts the temperature of the liquid to a preferred dissolution temperature, and controls the temperature and pressure of the liquid source, ensuring consistent dissolution conditions by using a thermally conductive conduit and a controller to manage the liquid temperature and pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a dispenser allows the container to iterate freely during dissolution, then the operation is simple, but the distance between the nozzle and product varies leading to inconsistent solution concentration
Solution Approach 1:
The patent controls the dissolution process by maintaining a constant distance parameter between the nozzle and product surface. This is achieved through a positioning mechanism that ensures the container iterates to a predetermined position where the nozzle-to-product distance is fixed, thereby maintaining consistent spray parameters and solution concentration throughout the dissolution cycle.
2Manufacturing precision
If the dispenser uses ambient temperature liquid, then the system is simple, but the dissolution temperature varies with operating environment affecting solution chemistry
Solution Approach 1:
The patent actively controls the liquid temperature parameter to maintain consistent dissolution conditions. A heating element and temperature sensor are used to regulate the liquid temperature at the nozzle, ensuring that the dissolution process occurs at a predetermined temperature regardless of ambient conditions, thereby achieving consistent solution chemistry and effectiveness.
3Manufacturing precision
If the dispenser allows variable spray parameters, then the device is adaptable to different conditions, but the solution concentration and effectiveness become inconsistent
Solution Approach 1:
The patent employs a feedback control system where sensors detect the actual position of the container and the temperature of the liquid, and this information is fed back to the control system. The controller adjusts the spray activation and heating elements accordingly to maintain the predetermined nozzle-to-product distance and liquid temperature, ensuring consistent dissolution parameters and solution concentration across varying operating conditions.

AI summary
A cast solid product dispenser for controlling the inputs and operating parameters of dissolution of a cast solid product is disclosed. The dispenser (10) includes a housing (12) having a cavity (18) for removably receiving a container (14) holding a cast solid product. The dispenser (10) includes means for controlling the temperature and pressure of liquid used for dissolution of the cast solid product. The dispenser (10) also includes a pedestal (20) for maintaining a constant distance between the surface of the product and a nozzle (48) during dissolution. The dissolution cycle includes a pulse of spray generally followed by a delay to allow liquid used in the dissolution process to adjust to a desired temperature. A pressure regulator (42) adjusts the pressure variation between various liquid sources so both the pressure and temperature of liquid used in the dissolution process is generally constant.
