Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spa systems do not efficiently utilize radiant heat and fail to maintain optimal water temperature control, leading to inefficient heating and filtration processes, as they rely on manual pump operation and lack adaptive temperature management.
Innovation Solution
An electronic data processing system is integrated with the spa, electronically coupling the heater and pump to independently manage their operation based on temperature differentials, ensuring efficient use of radiant heat and optimal water temperature control through phased temperature management and ozonization of water for enhanced filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual pump operation is used, then device complexity is reduced, but temperature control precision deteriorates
Solution Approach 1:
The system uses an electronic data processing system that automatically monitors temperature differentials and independently controls pump and heater operation without manual intervention. The system serves itself by making autonomous decisions about when to activate the pump and heater based on real-time temperature data, eliminating the need for complex manual control mechanisms while achieving precise temperature management.
2Use of energy by moving object
If heater and pump are operated together, then heating efficiency is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts pump and heater operation based on real-time temperature differential monitoring. The electronic data processing system independently controls each component, activating the pump and heater together only when the temperature differential indicates both are needed for efficient heating, and separating their operation when conditions change, thereby optimizing energy utilization and preventing unnecessary energy consumption.
3Productivity
If pump runs continuously, then filtration productivity is improved, but cavitation risk increases
Solution Approach 1:
The system implements periodic pump operation controlled by the electronic data processing system based on temperature differential thresholds. The pump operates intermittently rather than continuously, activating when filtration is needed and deactivating when temperature conditions indicate sufficient circulation, thereby maintaining filtration productivity while reducing cavitation risk through periodic rather than continuous operation.

AI summary
A spa has an insulated cabinet with an uninsulated shell disposed therein. A filter assembly is downstream of a water intake. A heater is downstream of the filter assembly and a pump is downstream of the heater. A diversion line is in fluid line connection with an outlet of the pump. An ozonizor is in fluid communication with the diversion line. The filter assembly is coupled to the diversion line. A data processing system is coupled to the heater, pump, a control panel and a temperature sensor, wherein the data processing system responsive to when the actual temperature of an amount of water in the shell is a magnitude in degrees below a set temperature 1) turns the heater off if it is on or does not turn the heater on if it is already off and 2) turns the pump on if it is off or if it is already running does not turn the pump off.
