Engineering Contradiction Analysis
1Power
If a boost circuit is connected to another control circuit to increase output power, then the power output is improved, but the control complexity increases resulting in higher failure rate
Solution Approach 1:
The patent combines the boost circuit and control circuit into a single integrated control circuit that directly controls the heating element. This merging eliminates the need for separate boost and control circuits, reducing overall system complexity while maintaining the required power output capability through direct switching control of the heating element.
Solution Approach 2:
The control circuit is designed to perform multiple functions: it directly controls the heating element's power output and inherently provides the voltage boosting function through its switching architecture. This multi-functional design eliminates the need for a separate boost circuit, simplifying the system while achieving both power amplification and control in one circuit.
2Power
If a boost circuit is connected to another control circuit to increase output power, then the power output is improved, but the failure rate increases
Solution Approach 1:
By merging the boost circuit and control circuit into one integrated unit, the patent reduces the number of connection points and interface components between separate circuits. This integration minimizes potential failure points associated with inter-circuit connections while maintaining the required high power output capability.
Solution Approach 2:
The patent extracts and eliminates the separate boost circuit from the system by incorporating its functionality directly into the control circuit. This removal of the redundant boost circuit component reduces the overall failure rate by eliminating potential failure sources while preserving the power amplification function through the control circuit's direct switching architecture.
