Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a storage container and heating source are used to heat water, then hot water can be supplied, but the device occupies more space and requires inconvenient setup
Solution Approach 1:
The patent extracts the heating function from a separate storage container system and integrates it directly into the water purifier body. The heating source is positioned within the purifier to directly heat water in the heating flow path, eliminating the need for a dedicated storage container and its associated setup requirements.
Solution Approach 2:
The patent merges the heating function with the water purification system by integrating the heating source and heating flow path within the purifier body. This combination allows the purifier to directly supply hot water without requiring a separate storage container, reducing space and improving convenience.
2Productivity
If heating means directly heats water in the flow path, then heating efficiency improves, but local overheating occurs causing steam generation
Solution Approach 1:
The patent applies local quality by designing a heating flow path where water flows along the heating source, ensuring that different sections of water receive appropriate heating. The flow path geometry and water flow distribution create uniform heat transfer throughout, preventing localized overheating zones that would cause steam generation.
Solution Approach 2:
The heating flow path acts as an intermediary between the heating source and the water. It distributes water uniformly across the heating source surface, ensuring even heat distribution and preventing direct concentrated heating that would cause local overheating and steam generation.
3Speed
If water is heated quickly to desired temperature, then user preference is satisfied, but energy consumption increases
Solution Approach 1:
The patent implements continuous heating as water flows through the heating flow path. The heating source continuously heats water throughout the flow process rather than heating a large volume at once, maintaining efficient energy utilization while achieving quick heating of the required amount of water.
Solution Approach 2:
The patent applies partial heating by only heating the specific amount of water that flows through the heating flow path at any given time. This avoids the energy waste of heating excessive water that would be stored and later used, achieving quick heating efficiency with optimized energy consumption.
