Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional battery pack uses a single type of communication terminal (analog or digital), then the device structure is simple, but it becomes incompatible with external devices that require different communication types

Engineering Contradiction:
Improvecompatibility with external devicesVSAvoidcommunication terminal structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The battery pack is equipped with multiple types of communication terminals (both analog and digital) and multiple communication modules that can adaptively switch between different communication protocols. This allows a single battery pack design to interface with various external devices using different communication standards, achieving universal compatibility without requiring multiple specialized battery pack designs

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

2Adaptability or versatility

If the battery pack includes multiple communication modules for different protocols, then compatibility with external devices is improved, but the device complexity increases

Engineering Contradiction:
Improvecommunication protocol compatibilityVSAvoidcontrol module structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control module dynamically selects and activates the appropriate communication module based on the type of external device detected. The system can switch between analog and digital communication modes, and between different digital protocols (such as CAN and serial communication), thereby adapting to different communication requirements without maintaining all modules simultaneously active, which reduces the effective complexity

Inventive Principle:
Principle #15Dynamics
