Solution Overview

Problem

Existing electrolytic liquid production devices face issues with the elastic body being inaccurately positioned inside the housing, leading to variable pressing forces on the electrolyzer and instability in electrolytic treatment performance.

Innovation Solution

The device incorporates a housing design with positioning protruding and depressed portions to secure the elastic body, ensuring uniform pressing force on the electrolyzer by aligning the elastic body with the housing, thereby stabilizing the electrolytic treatment process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the elastic body is disposed inside the housing without positioning structures, then the device complexity is reduced, but the elastic body becomes biased and the electrolytic treatment performance becomes unstable

Engineering Contradiction:
Improvestructure complexityVSAvoidelectrolytic treatment performance stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

Positioning protruding portions are provided on the housing and positioning depressed portions are provided on the elastic body before assembly. These positioning structures are pre-formed to guide the elastic body into the correct position, preventing bias and ensuring stable electrolytic treatment performance without requiring complex adjustment mechanisms during operation.

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If the elastic body is inaccurately positioned inside the housing, then the ease of manufacture is improved, but the pressing force on the electrolyzer becomes variable and the electrolytic treatment performance becomes unstable

Engineering Contradiction:
Improveassembly easeVSAvoidelastic body positioning accuracy
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The positioning protruding portions on the housing and positioning depressed portions on the elastic body create a self-positioning mechanism during assembly. The elastic body automatically aligns itself with the correct position through these complementary geometric features, eliminating the need for complex external positioning tools or procedures while ensuring high positioning accuracy.

Inventive Principle:
Principle #25Self-service
