Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless power transmission is implemented without a user interface for parameter adjustment, then the device structure remains simple, but user control and adaptability are poor

Engineering Contradiction:
Improveuser control of wireless power transmissionVSAvoidinterface structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements a user interface that displays real-time wireless power transmission parameters (power level, distance, temperature) and allows users to adjust settings based on feedback from sensors. This enables users to control power transmission parameters while the system monitors and adjusts based on environmental conditions, resolving the contradiction between user control and device simplicity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system automatically adjusts certain parameters based on sensor data (temperature, distance detection) without requiring constant user intervention. The processor autonomously manages power transmission parameters while providing users high-level control options, balancing user control with automated system management.

Inventive Principle:
Principle #25Self-service

2Productivity

If multiple parameters are monitored and adjusted for optimal wireless power transmission, then power transmission efficiency is improved, but the device complexity increases

Engineering Contradiction:
Improvewireless power transmission efficiencyVSAvoidparameter monitoring and control system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent uses a multi-functional processor that handles both the complex task of monitoring multiple parameters (temperature, distance, power level) and the simpler task of user interface management. The same processor also controls the power transmission coil and communicates with external devices, consolidating multiple functions into a single component to minimize added complexity while maintaining high transmission efficiency.

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

Solution Approach 2:

The patent introduces a communication circuit as an intermediary that manages data exchange between the sensor module, processor, and external electronic device. This intermediary layer simplifies the overall system architecture by centralizing communication functions, allowing efficient parameter monitoring without proportionally increasing device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
