Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual power adaptation is required for each small household appliance, then power supply accuracy can be maintained, but ease of operation deteriorates due to complex user settings
Solution Approach 1:
The control unit automatically identifies the small household appliance and determines its power requirements without user intervention. The system performs self-service by reading appliance parameters, determining maximum power, and automatically selecting appropriate power levels, eliminating the need for manual user configuration while maintaining precise power supply.
Solution Approach 2:
The control unit receives feedback from the small household appliance through communication interfaces to automatically determine power requirements. The system uses bidirectional communication to obtain appliance identification information and power parameters, then adjusts the inductively provided energy based on this feedback to achieve accurate power supply without manual user input.
2Ease of operation
If power is inductively provided without automatic identification, then ease of operation is maintained, but reliability deteriorates due to potential oversupply and damage to appliances
Solution Approach 1:
The control unit performs preliminary identification of the small household appliance before providing inductive power. The system automatically determines the appliance's maximum power and number of power levels in advance, then uses this information to safely control the energy supply, preventing oversupply and potential damage while maintaining simple operation for the user.
Solution Approach 2:
The control unit continuously receives feedback from the small household appliance regarding its power requirements and operating state. Based on this feedback, the system automatically adjusts the inductively provided energy to match the appliance's actual needs, ensuring safe operation and preventing damage while requiring minimal user intervention.
3Measurement precision
If the control unit is configured individually for specific small household appliances, then power supply precision is improved, but device complexity increases
Solution Approach 1:
The control unit is designed with universal functionality to automatically identify and work with multiple types of small household appliances. Instead of requiring individual configuration for each appliance type, the control unit uses communication interfaces to automatically read and adapt to the specific parameters of any connected appliance, providing precise power adaptation through a single versatile device.
Solution Approach 2:
The control unit performs self-configuration by automatically identifying the connected small household appliance and determining its power requirements. The system reads appliance parameters through communication interfaces, stores them in memory, and uses this information to automatically control power supply, eliminating the need for manual individual configuration while maintaining precise power adaptation.
4Adaptability or versatility
If multiple small household appliances with different power requirements are supported, then adaptability is improved, but difficulty of detecting and measuring increases
Solution Approach 1:
The control unit uses bidirectional communication interfaces to receive feedback from multiple small household appliances regarding their identification, maximum power, and power level requirements. This automated feedback mechanism allows the system to detect and measure appliance parameters without complex manual procedures, enabling support for diverse appliances with different power requirements while keeping the detection process simple and automatic.
Solution Approach 2:
Each small household appliance provides self-service by transmitting its identification information and power parameters to the control unit through communication interfaces. The control unit automatically reads and stores these parameters in memory, enabling the system to adapt to multiple different appliances without requiring complex detection procedures, thus achieving high adaptability with simplified parameter detection.
