Solution Overview
Problem
Residential water heating using electrode boilers poses safety hazards due to the risk of electric leaks when the electrified water comes into contact with users, as the existing technology does not effectively isolate the electric potential of the water from the electric grid supply.
Innovation Solution
A boiler design featuring electrodes immersed in water with a separating circuit that isolates the electric power supply from the electrodes, using a transformer or capacitor to ensure the water is electrified independently of the grid supply, eliminating the risk of electric leaks and grounding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If electrodes are directly connected to the electric grid supply for water heating, then heating efficiency is improved, but safety deteriorates due to electric leak hazards
Solution Approach 1:
A separating circuit is introduced as an intermediary component between the electric grid supply and the electrodes. This circuit electrically isolates the electrodes from direct connection to the grid while still allowing power transfer, thereby eliminating the electric leak hazard to users while preserving the electrode heating function
2Object-affected harmful factors
If a separating circuit is introduced to isolate electrodes from grid supply, then safety is improved, but device complexity increases
Solution Approach 1:
The separating circuit serves as a compact intermediary device that provides electrical isolation through transformer or capacitor-based design. While it adds a component to the system, the circuit integrates into the existing boiler structure without requiring major redesign, thus managing the increase in complexity while achieving safety
3Object-affected harmful factors
If grounding is eliminated through electrical separation, then safety is improved, but adaptability to different electrical systems is reduced
Solution Approach 1:
The separating circuit acts as a universal intermediary that can interface with different grid supply configurations (single-phase, three-phase, different voltages) while maintaining electrical isolation. The circuit design allows flexibility in connecting to various electrical systems without requiring grounding, thus preserving adaptability while ensuring safety
