Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Induction heating in water purifiers faces challenges in maintaining a consistent gap between the coil and the hot water tank, leading to inefficient heating, where high power can boil water excessively and low power fails to heat it sufficiently.
Innovation Solution
A water purifier design incorporating a spacer made of materials like mica, glass, or silicon to maintain a constant gap between the working coil and the hot water tank, ensuring accurate induction heating by preventing deformation and ensuring sufficient heating time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gap between the coil and hot water tank is not maintained, then the device complexity is reduced, but the heating efficiency deteriorates and temperature control becomes unreliable
Solution Approach 1:
A spacer is introduced as an intermediary component between the coil and the hot water tank. This spacer maintains a constant gap to ensure reliable induction heating while preventing direct contact that would cause deformation. The spacer is a simple structural element that resolves the contradiction by providing the necessary separation without adding complex control mechanisms.
2Productivity
If high power induction heating is applied, then heating speed is improved, but water boils excessively and temperature control is lost
Solution Approach 1:
The patent replaces mechanical contact-based heating control with electromagnetic induction heating. By maintaining a constant gap through the spacer, the system enables efficient electromagnetic coupling for rapid heating while preventing direct thermal contact that would lead to overheating and boiling. This substitution allows high-power heating without excessive temperature rise.
3Reliability
If low power induction heating is applied, then temperature control is improved, but water is not heated sufficiently
Solution Approach 1:
The spacer acts as a mediator that optimizes the electromagnetic coupling between the coil and the hot water tank. By maintaining a precise constant gap, it ensures that even at lower power levels, the induction heating is sufficiently efficient to heat the water adequately, while still allowing for reliable temperature control when needed.
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 ensures consistent and efficient heating of water, preventing deformation of the hot water tank and ensuring that water is heated adequately without boiling excessively, thus providing a reliable temperature control.
Implementation Method 1
Induction heating indicates a heating method of heating an object to be heated using electromagnetic induction. When a current is supplied to a coil, an eddy current is generated on the object to be heated
Implementation Method 2
Joule heating generated by a resistance of the metal increases the temperature of the object to be heated

AI summary
A water purifier includes a working coil, a hot water tank that faces toward the working coil and is spaced apart from the working coil by a gap to heat a liquid passing through an inner space of the hot water tank by an induction of the working coil, a bracket that is coupled to the hot water tank, the working coil being located between the hot water tank and the bracket, and a spacer that is located between the working coil and the hot water tank to thereby define the gap between the working coil and the hot water tank.
