Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate heating element and power receiver are provided, then heating and charging functions are achieved, but device complexity increases
Solution Approach 1:
The induction coil is designed to perform multiple functions: it serves as both the heating element that generates magnetic fields to heat the susceptor and the power receiver that wirelessly receives charging power from the charging device. This multi-functionality eliminates the need for separate heating elements and power receivers, thereby reducing device complexity while maintaining both heating and charging capabilities
Solution Approach 2:
The patent combines the heating element and power receiver into a single induction coil component. By merging these two previously separate functions into one component, the overall device structure is simplified, fewer parts are required, and device complexity is reduced while still achieving both heating and charging operations
2Loss of energy
If impedance matching components are added, then power transfer efficiency is improved, but device complexity increases
Solution Approach 1:
Impedance matching components are introduced as intermediary elements between the induction coil and the circuit. These components act as mediators that optimize the transfer of power by matching impedance levels, thereby reducing energy loss and improving power transfer efficiency. The impedance matching components are strategically placed to ensure efficient power transfer without causing significant device complexity
Solution Approach 2:
The impedance matching components enable optimization of power transfer by adjusting and matching impedance parameters. By changing and optimizing the impedance parameters at different stages of power transfer, the system achieves higher efficiency. This parameter optimization approach allows for improved power transfer without requiring fundamental changes to the device structure
3Device complexity
If the induction coil is used for both heating and charging, then device complexity is reduced, but simultaneous operation control becomes difficult
Solution Approach 1:
The system employs periodic action by clearly separating heating operation and charging operation into distinct time periods. The controller switches between these two modes, ensuring that heating and charging do not occur simultaneously. This periodic separation of functions allows the single induction coil to perform both roles without interference, maintaining ease of operation control while reducing device complexity
Solution Approach 2:
The system implements dynamic control by using a controller that can switch the induction coil between different operational modes (heating mode and charging mode). This dynamic switching capability allows the system to adapt its function based on operational requirements, ensuring that the single induction coil can be effectively controlled for different purposes without simultaneous operation conflicts
