Solution Approach 1:

A water-permeable membrane is introduced as an intermediary component between the cathode and anode. The membrane allows water molecules to pass through while maintaining a stable separation distance, preventing direct contact and short-circuiting between electrodes during electrolysis operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs a thin water-permeable membrane to separate the electrodes. This thin film structure maintains close proximity for efficient electrolysis while preventing electrode contact and short-circuiting, solving the contradiction between efficiency and stability.

Inventive Principle:
Principle #30Flexible shells and thin films

2Reliability

If physical filtering membranes are used to purify water, then hazardous substances are blocked, but the membranes are easily polluted by bacteria or blocked by organic substances

Engineering Contradiction:
