Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional power supply unit is used for charging and discharging battery cells, then it can charge and discharge a single battery cell, but it requires replacement when the battery cell standard changes and cannot simultaneously charge multiple cells

Engineering Contradiction:
Improveadaptability to different battery cell standardsVSAvoidcomplexity of power supply unit replacement
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The power supply unit is designed with multiple output terminals that can simultaneously connect to multiple battery cells through a jig with multiple sockets. This allows a single power supply unit to charge and discharge multiple battery cells of different standards concurrently, eliminating the need for replacement and achieving multi-functionality.

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

Solution Approach 2:

The connection between the power supply unit and battery cells is segmented into multiple independent connection paths through the jig structure. Each socket in the jig can independently connect to different battery cell terminals, allowing flexible configuration for different battery standards and simultaneous operation with multiple cells.

Inventive Principle:
Principle #1Segmentation

2Productivity

If a single power supply unit charges multiple battery cells sequentially, then it can handle different battery standards, but the charging and discharging efficiency is reduced

Engineering Contradiction:
Improvecharging and discharging efficiencyVSAvoidtime for sequential charging and discharging
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The power supply unit's output is segmented into multiple independent channels through multiple output terminals, each capable of independently charging or discharging a battery cell. This parallel segmentation enables simultaneous operation with multiple battery cells, dramatically improving productivity and eliminating sequential processing time losses.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the jig structure is designed for fixed battery cell standards, then it simplifies the connection structure, but it cannot adapt to different battery cell standards

Engineering Contradiction:
Improveadaptability to different battery cell standardsVSAvoidease of connection and configuration
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The jig is designed with multiple sockets that can universally accommodate different battery cell standards. Each socket is configured with multiple connection points that can adapt to various terminal arrangements, allowing the same jig structure to work with different battery standards without modification while maintaining ease of operation through standardized connection interfaces.

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

Solution Approach 2:

The connection configuration of the jig is made dynamic and reconfigurable rather than fixed. The sockets and connection terminals can be dynamically adjusted or reconfigured to match different battery cell standards, providing adaptability while maintaining operational simplicity through a flexible but standardized connection system.

Inventive Principle:
Principle #15Dynamics
