Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the battery capacity is increased to extend operational time, then the device weight and volume increase, but portability is compromised

Engineering Contradiction:
Improveoperational timeVSAvoiddevice weight
Core Design Contradiction:
Duration of action of moving objectVSWeight of moving object

Solution Approach 1:

The system performs preliminary detection of external device types before charging begins, and pre-configures the appropriate charging mode (standard or direct charging) based on the detected device characteristics. This allows the system to prepare optimal charging parameters in advance, extending operational time without requiring excessive battery capacity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically changes charging parameters (voltage, current) based on the detected external device type. When a power source adapter for direct charging is detected, the system switches to direct charging mode with higher voltage parameters, efficiently extending operational time without increasing physical battery size or device weight.

Inventive Principle:
Principle #35Parameter changes

2Duration of action of moving object

If the battery capacity is increased to extend operational time, then the device volume increases, but portability is compromised

Engineering Contradiction:

Core Design Contradiction:
Duration of action of moving objectVSVolume of moving object

Solution Approach 1:

The system detects external device types and configures charging modes before charging starts, allowing efficient use of available battery capacity. This preliminary configuration enables extended operational time without requiring larger battery volume.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system changes charging voltage and current parameters based on detected device type, enabling more efficient charging that extends operational time without increasing battery volume.

Inventive Principle:

3Adaptability or versatility

If the system supports multiple charging modes and device types, then the charging system complexity increases, but identification and control difficulty increases

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system automatically detects external device types and self-configures the appropriate charging mode without user intervention. The microprocessor autonomously identifies power source adapters for direct charging and switches charging parameters accordingly, maintaining simplicity despite supporting multiple charging modes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback from external device identification to dynamically adjust charging parameters. By detecting device characteristics and receiving feedback during charging, the system automatically optimizes charging mode, managing complexity through intelligent control rather than multiple physical charging circuits.

Inventive Principle:
Principle #23Feedback

4Ease of operation

If automatic device identification is implemented to improve charging efficiency, then the need for manual configuration is reduced, but initial device detection time increases

Engineering Contradiction:

Solution Approach 1:

The system performs automatic device identification and self-configures charging parameters without requiring manual user configuration. This self-service approach improves ease of operation by eliminating manual steps, and the detection process is optimized to minimize time loss through efficient wireless communication protocols.

Inventive Principle:
Principle #25Self-service
