Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the number of electrode plate stacking apparatuses is increased to increase manufacturing capacity, then the manufacturing capacity for electrode plate stack structures is improved, but the installation area and costs increase

Engineering Contradiction:

Improvemanufacturing capacityVSAvoidinstallation area

Core Design Contradiction:

ProductivityVSArea of stationary object

Solution Approach 1:

The patent combines multiple separator supply functions into a single integrated apparatus. The stacking stage is configured to clamp multiple separators simultaneously, and electrode plate supplies are positioned to alternately supply positive and negative electrode plates to multiple separators in one device, thereby increasing manufacturing capacity without proportionally increasing installation area

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The stacking stage serves multiple functions: it clamps separators, receives electrode plates, and facilitates the formation of electrode plate stack structures. The single apparatus performs what would traditionally require multiple separate devices, making the system more space-efficient while maintaining high productivity

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

Engineering Contradiction:

Improvemanufacturing capacityVSAvoidcosts

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

By merging multiple separator supply functions into one apparatus, the patent reduces the total number of devices needed in the production line. This consolidation lowers equipment costs, installation costs, and maintenance costs while achieving the same or higher manufacturing capacity

Inventive Principle:

Principle #5Merging (Combining)

3Area of stationary object

If a single electrode plate stacking apparatus is used to reduce installation area and costs, then the installation area and costs are reduced, but the manufacturing capacity remains the same or decreases

Engineering Contradiction:

Improveinstallation areaVSAvoidmanufacturing capacity

Core Design Contradiction:

Area of stationary objectVSProductivity

Solution Approach 1:

The patent utilizes the vertical dimension by positioning electrode plate supplies on opposite sides of the stacking stage, allowing simultaneous supply of positive and negative electrode plates to multiple separators. This three-dimensional arrangement enables high-capacity production within a compact footprint

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
