Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deionization apparatuses face challenges in simplifying the replacement of ion-exchange resin, inefficient recycling of resin, and increased space requirements due to complex maintenance processes and the need for complete resin replacement.
Innovation Solution
The ion-exchange resin module features a modular design with a pressing plate and handle system that allows for efficient discharge and recycling of ion-exchange resin, minimizing space usage and maintenance time by allowing introduction and discharge pipes to connect at the lower end of the tank, enabling selective recycling of ion-exchange resin based on deionization capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the cap is removed to replace ion-exchange resin, then the resin can be discharged and replaced, but the introduction pipe must be disconnected from the connecting pipe which complicates the replacement process
Solution Approach 1:
The deionization apparatus is divided into separable modules: the tank with cap can be removed independently from the connecting pipe, while the introduction pipe remains connected to the connecting pipe. This segmentation allows the cap and tank to be replaced without disconnecting the introduction pipe from the connecting pipe, simplifying the resin replacement process.
2Loss of substance
If water is drained through the drain valve during resin replacement, then water can be removed from the inner space, but water containing glycol is not completely drained and is discharged with the resin preventing reuse
Solution Approach 1:
The pressurization chamber is used to apply pressure specifically to the lower portion of the ion-exchange resin where retained water is located. This targeted pressurization extracts the retained water containing glycol from the resin, allowing the resin to be reused and the coolant to be recovered, thereby reducing coolant loss.
3Ease of manufacture
If the introduction pipe passes through a portion higher than the tank, then the pipe connection is achieved, but the space for installing the deionization apparatus is increased
Solution Approach 1:
The introduction pipe is repositioned to pass through the lower end of the tank instead of passing through a higher portion. This dimensional change in pipe routing eliminates the need for additional lateral space, reducing the overall installation footprint while maintaining proper connection to the connecting pipe.
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
This design simplifies resin replacement, reduces maintenance time, and maximizes resin recycling efficiency, minimizing coolant discharge and space requirements while maintaining effective deionization performance.
Implementation Method 1
Ion-exchange resin is used to make pure water used in industrial sites or to remove ions from water used as a coolant. Water to be deionized is transmitted to the inside of a tank containing the ion-exchange resin, and as the water passes through the ion-exchange resin, cations or anions contained in the water are removed

AI summary
An ion-exchange resin module and a deionization apparatus using same are proposed. An ion-exchange resin module may have the inside filled with ion-exchange resin and may be configured to have a pressing plate such that fluid in the ion-exchange resin is discharged. Multiple ion-exchange resin modules may be installed by being stacked in an inner space defined inside a tank of the deionization apparatus. A discharge pipe which passes through the lower end of the tank and extends to the upper end thereof may be installed in the inner space, the discharge pipe being located in a through duct which passes through the centers of the ion-exchange resin modules.
