Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional pipe-type electrolysis cells are used with multiple parts and complex assembly, then electrolysis function is achieved, but manufacturing cost increases and device complexity increases

Engineering Contradiction:
Improvemanufacturing costVSAvoidnumber of parts
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines multiple separate components (electrode, insulating spacer, connection structures) into an integrated molded structure. The insulating spacer is molded directly onto the electrode, eliminating the need for separate assembly steps and reducing the total number of parts while maintaining the electrolysis function.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The molded structure serves multiple functions simultaneously: the electrode provides electrical conduction for electrolysis, the integrated insulating spacer provides electrical insulation and structural support, and the unified design simplifies assembly. This multi-functionality reduces both part count and manufacturing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If conventional pipe-type electrolysis cells with large size are used, then adequate electrolysis capacity is achieved, but installation space requirement increases

Engineering Contradiction:
Improveelectrolysis capacityVSAvoidinstallation space
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The patent transitions from a conventional two-dimensional electrode surface to a three-dimensional molded structure where the electrode extends in multiple spatial dimensions. This allows increased electrolysis surface area within a compact volume, improving capacity while reducing installation space requirements.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If conventional electrode design with non-uniform current distribution is used, then electrolysis occurs, but reaction uniformity decreases and heat generation increases

Engineering Contradiction:
Improvereaction uniformityVSAvoidheat generation
Core Design Contradiction:
ProductivityVSTemperature

Solution Approach 1:

The molded structure incorporates locally optimized electrode geometry and insulating features that ensure uniform current distribution across different regions of the electrode surface. This local quality control prevents current concentration in specific areas, improving reaction uniformity and reducing localized heat generation.

Inventive Principle:
Principle #3Local quality
