Solution Overview
Problem
Existing drinking water purification systems face challenges in quickly and safely disinfecting water lines without increasing the risk of leakage or requiring significant additional equipment.
Innovation Solution
A drinking water purification system that includes a filtering unit with a replaceable filter cartridge, a connection adapter for fluid connection between the hot and cold water lines, and a heater to deliver heated water for disinfection, allowing for efficient flushing of the cold water line up to the faucet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate disinfection system is added to the drinking water purification system, then the disinfection capability is improved, but the device complexity and equipment expenditure increase
Solution Approach 1:
The hot water line is designed to serve dual purposes: providing hot water for normal use and serving as a disinfection medium for the cold water line. The connection adapter enables the hot water line to be temporarily connected to the cold water line cartridge holder, allowing heated water to flush through and disinfect the drinking water lines without requiring a separate disinfection system.
Solution Approach 2:
The system uses its own existing hot water heating capability to perform disinfection of the cold water line. The heater associated with the hot water line heats water that then flows through the cold water line via the connection adapter, enabling the system to disinfect itself using resources already available within the system.
2Reliability
If traditional disinfection methods are used, then water line disinfection is achieved, but the process is time-consuming and complex
Solution Approach 1:
The system changes the temperature parameter of the water used for disinfection by utilizing heated water from the hot water line (typically at temperatures suitable for disinfection, e.g., above 60°C). This thermal parameter change enables effective disinfection while simplifying the process, as the heated water naturally flows through the cold water line to achieve purification without requiring additional time-consuming steps.
3Reliability
If the connection adapter is used to connect hot and cold water lines, then disinfection capability is improved, but the risk of leakage increases
Solution Approach 1:
The connection adapter serves as an intermediary component that safely connects the hot water line to the cold water line cartridge holder. This specialized adapter is designed to create a secure, leak-proof connection between the two lines, enabling the disinfection function while minimizing leakage risk through proper sealing and connection mechanisms.
