Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If the storage tank is opened to discharge vapor and prevent pressure increase, then the pressure inside the circulation path is reduced, but fluid may be spilled out and external contaminants may enter
Solution Approach 1:
The patent employs a flexible diaphragm membrane to seal the opening in the storage tank. This thin film structure allows vapor to pass through while preventing liquid fluid from spilling out and blocking external contaminants from entering, thus resolving the contradiction between pressure relief and contamination prevention
Solution Approach 2:
The diaphragm membrane is designed as a porous structure with specific pore sizes that permit vapor molecules to pass through while physically blocking larger fluid molecules and external contaminants. This selective permeability enables pressure equalization without fluid loss or contamination
2Object-affected harmful factors
If the storage tank is sealed to prevent fluid spillage and contamination, then fluid discharge and contamination are prevented, but pressure increases due to vaporization
Solution Approach 1:
The sealed storage tank incorporates a flexible diaphragm membrane that maintains the seal while allowing pressure equalization through vapor passage, thus preventing fluid spillage and contamination while avoiding dangerous pressure buildup
Solution Approach 2:
The diaphragm membrane acts as an intermediary element between the sealed interior and exterior environments, mediating the pressure balance by allowing vapor transmission while maintaining the seal against fluid loss and contamination
3Stress or pressure
If a conventional opening is used to release vapor, then pressure is reduced, but foreign substances may enter and damage pump and check valve
Solution Approach 1:
The diaphragm membrane's controlled porosity allows vapor molecules to pass through while physically blocking larger foreign substances such as dust and debris, thus reducing pressure without compromising the reliability of the pump and check valve
Solution Approach 2:
The flexible diaphragm membrane provides a protected vapor release pathway that filters out foreign substances, preventing them from entering the circulation system and damaging sensitive components like the pump and check valve

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents pressure increase and contamination, ensuring device safety and component integrity by selectively discharging vapor and blocking fluid and external substances, thus preventing damage and maintaining safe operation.
Implementation Method 1
an overpressure prevention member configured to close the opening, and the overpressure prevention member is configured to prevent the fluid from passing therethrough and to allow a vapor of the fluid to pass therethrough so as to reduce a pressure inside the storage tank and the circulation line
Implementation Method 2
when a fluid, for example, water is heated, a part of the water becomes a vapor, thereby increasing and the internal pressure of a water circulation path

AI summary
The present invention relates to a fluid circulation type heating device which circulates fluid by means of heating and cooling and, more particularly, to a fluid circulation type heating device provided with overpressure protection element which can prevent pressure increase of a circulation path of a fluid. The fluid circulation type heating device according to the present invention for achieving the aforementioned purpose comprises a circulation line, a heat radiation member installed on the circulation line, a boiler which heats and expands a fluid, a storage tank which stores the fluid therein and supplies the same to the boiler, a controller which controls the boiler, and a housing which accommodates the boiler and the controller. In addition, the device has an opening formed in fluid communication with the storage tank or the circulation line, and further comprises an overpressure protection element which blocks the opening, wherein the overpressure protection element is configured to prevent fluid from passing through and allowing a vapor of the fluid to pass through, thereby dropping the pressure of the storage tank and the circulation line. The fluid circulation type heating device according to the present invention discharges, to the outside, steam from the inside of a circulation path and does not discharge fluid to the outside, thereby preventing overpressure loaded onto the fluid circulation path of a heating device. In addition, should the heating device fall over, it is possible to prevent fluid from being discharged to the outside. Furthermore, it is possible to prevent external foreign material from being introduced into the circulation path, thereby preventing damages of components or generation of odor, due to contamination of fluid caused from the external foreign material.
