Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple quick charging protocols are stored in the terminal device, then compatibility with different charging connection devices is improved, but device complexity increases

Engineering Contradiction:
ImprovecompatibilityVSAvoidcomplexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The terminal device is designed to support multiple quick charging protocols (such as QC3.0, QC4.0, PD, FCP, SCP) simultaneously, enabling a single device to function with various charging connection devices. The charging controller automatically detects and adapts to different protocols, making the terminal device universal and eliminating the need for users to carry multiple adapters.

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

2Productivity

If dedicated charging devices are used for each quick charging protocol, then charging efficiency is maintained, but user convenience deteriorates

Engineering Contradiction:
Improvecharging efficiencyVSAvoiduser convenience
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The charging controller dynamically detects which quick charging protocol the charging connection device supports and automatically switches between different protocols. This dynamic adaptation allows the system to maintain optimal charging efficiency for each protocol while providing users with a simple, unified charging interface, eliminating the need for manual protocol selection or carrying multiple dedicated chargers.

Inventive Principle:
Principle #15Dynamics
