Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a dedicated cradle is used to switch charging voltage or current based on battery type, then charging accuracy for specific battery types is improved, but device complexity and requirement for specialized equipment increases

Engineering Contradiction:
Improvecharging accuracyVSAvoidequipment specialization
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The radiation imaging apparatus integrates battery type identification and adaptive charging control functions directly into the apparatus itself, eliminating the need for dedicated cradles. The control unit automatically detects battery type and adjusts charging parameters accordingly, making the apparatus universally compatible with multiple battery types while maintaining precise charging control.

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

Solution Approach 2:

The patent combines the battery type identification function and charging control function into a single integrated system within the radiation imaging apparatus. The control unit performs both battery recognition and charging parameter adjustment, merging what were previously separate functions (cradle-based type detection and charging control) into one unified device.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple battery types are supported, then adaptability and versatility are improved, but charging control complexity increases

Engineering Contradiction:
Improvebattery type compatibilityVSAvoidcharging control complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control unit automatically performs battery type identification and selects appropriate charging parameters without user intervention. The system self-adjusts charging voltage and current based on the detected battery type, eliminating the need for manual configuration and simplifying user operation while supporting multiple battery types.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements automatic adjustment of charging parameters (voltage and current) based on detected battery type. The control unit modifies electrical parameters dynamically according to the specific battery characteristics, enabling versatile battery support through automated parameter optimization rather than fixed charging modes.

Inventive Principle:
Principle #35Parameter changes
