Non-electric Water Purifier Connector Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water purifiers require significant effort and time to replace the flow path between the water-purifying filter and the water outlet cock, and there is a risk of water leakage and incomplete sterilization of contaminants and bacteria.
Innovation Solution
A non-electric water purifier design that allows for the one-touch replacement of the connector, which includes both the raw water and purified water passages, between the water-purifying filter and the water outlet cock, ensuring complete replacement and minimizing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the flow path is replaced by disassembling and reassembling multiple parts, then the replacement can be performed with conventional components, but it takes too much work time and effort and water leakage may occur through connection portions
Solution Approach 1:
The flow path replacement system is divided into modular components: a connector assembly that can be detached from the main body, and a filter assembly that can be removed and replaced independently. This segmentation allows each module to be replaced separately without requiring complete disassembly of the entire water purifier system.
Solution Approach 2:
The connector and flow path components are merged into a single replaceable assembly unit. By combining the connector body, inlet/outlet ports, and flow channels into one integrated component, the system enables replacement of the entire flow path through a single insertion/removal action, eliminating multiple connection and disconnection steps.
2Ease of manufacture
If the flow path is replaced by disassembling and reassembling multiple parts, then conventional components can be used, but water leakage may occur through connection portions between new parts
Solution Approach 1:
The connector and flow path components are merged into a single replaceable assembly unit. By combining the connector body, inlet/outlet ports, and flow channels into one integrated component, the system eliminates multiple connection interfaces that could potentially leak, reducing the risk of water leakage at connection points.
Solution Approach 2:
The connector assembly is designed as a disposable or limited-life component that is replaced periodically rather than maintained indefinitely. This approach ensures that connection interfaces remain intact and reliable throughout their service life, eliminating leakage issues that would arise from repeated assembly and disassembly of permanent components.
3Reliability
If a stainless steel pipe is used as the flow path, then high-temperature steam or sterilizing agents can be circulated to perform sterilization, but contaminants or bacteria occurring in the flow path cannot be completely sterilized
Solution Approach 1:
The flow path connector assembly is extracted as a separate, removable component from the main water purifier body. This allows the connector to be completely removed and replaced periodically, taking out the accumulated contaminants and bacteria that cannot be eliminated by sterilization processes alone, thereby ensuring continuous hygiene of the water system.
4Object-affected harmful factors
If the connector is made replaceable and rotatable, then the flow path can be completely replaced to prevent contamination, but the coupling mechanism becomes more complex
Solution Approach 1:
The connector assembly is designed with universal coupling features that enable multiple functions: secure attachment to the main body, rotational movement for alignment, and easy detachment for replacement. These multi-functional design elements are integrated into a single standardized interface, avoiding the need for separate complex mechanisms for each function.

AI summary
Proposed is a non-electric water purifier in which a flow path provided between a water-purifying filter and a water outlet cock is replaced in order to minimize contamination of purified drinking water. The non-electric water purifier includes a main body having a door formed on one side thereof so as to open and close the main body and having and having a receiving space part defined therein, a connector which is coupled replaceably and rotatably to one side of the main body and incudes a raw water passage connected to a raw water inlet and a purified water passage through which purified water flows, at least one filter housing being received in the receiving space part, with a discharge outlet of the filter housing being coupled detachably to the connector, and the water outlet cock which is connected to a discharge opening of the connector and discharges purified water.
