Preheated Liquid Storage Tank for Shorter Temperature Settling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing examination devices require a significant settling time for liquids to reach the desired temperature before discharge, particularly in temperature-controlled washing solutions, due to the need for heating within conduits which prolongs the process.
Innovation Solution
A liquid storage device with a heat retention tank and a heating unit on the supply conduit, controlled by a processor to maintain and adjust the temperature of the liquid before storage, ensuring it is at the desired temperature for discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the washing solution is fed to the heating block and heated, then the liquid reaches the desired temperature, but the settling time is prolonged
Solution Approach 1:
The patent applies preliminary action by heating the liquid in the supply conduit before it enters the heat retention tank. The heating unit is positioned in the supply conduit to pre-heat the liquid, so that when the liquid is stored in the heat retention tank, it is already at or near the desired temperature, significantly reducing the settling time required for the liquid to reach the target temperature after storage.
2Temperature
If a heating function is provided in the heat retention tank, then temperature control is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the heating function from the heat retention tank by positioning the heating unit in the supply conduit instead. This separation allows the heat retention tank to focus solely on storage with heat insulating properties, while the heating function is performed separately in the conduit before the liquid enters the tank. This reduces the complexity of the heat retention tank itself while maintaining effective temperature control.
3Loss of time
If the liquid is heated in the supply conduit, then the settling time is shortened, but energy consumption increases
Solution Approach 1:
The patent applies local quality by positioning the heating unit specifically in the supply conduit where the liquid flows before storage, rather than heating the entire volume of liquid in the heat retention tank. This localized heating approach concentrates energy usage in the most critical area for rapid temperature adjustment, achieving short settling times while minimizing overall energy consumption by avoiding redundant heating of already-heated liquid in the storage tank.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device significantly reduces the settling time by pre-heating the liquid to the required temperature before discharge, maintaining temperature stability, and preventing property degradation of solutions like BF separation solutions.
Implementation Method 1
a heating unit that is disposed on the supply conduit and heats the liquid passing through the supply conduit
Implementation Method 2

AI summary
A liquid storage device includes a distribution unit that supplies a liquid to a nozzle; a heat retention tank having a heat insulating function that is connected to the distribution unit and stores the liquid; a pump that sucks the liquid to be replenished to the tank from an outside; a supply conduit that guides the liquid sucked by the pump to the heat retention tank; a temperature sensor that detects a temperature of the liquid passing through the supply conduit; a heating unit that heats the liquid passing through the supply conduit; and a processor that is configured to execute a process of, in a case where the liquid is replenished to the heat retention tank, heating the liquid sucked into the supply conduit by the pump to a temperature set in advance in the supply conduit and replenishing the liquid heated in the supply conduit to the heat retention tank by acquiring information related to the temperature from the temperature sensor and controlling the heating unit.
