Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Induction-based vaporizers lack temperature feedback sensors to regulate power to the inductor for achieving a desired set-point temperature, leading to inaccurate temperature control and potential interference with outside electronics.
Innovation Solution
Incorporation of a non-contact type temperature sensor, such as a thermopile or infrared sensor, to measure the temperature of the workpiece and provide feedback to the induction heating system, allowing precise control of the heating process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If induction heating system is used without temperature feedback sensor, then device complexity is reduced, but temperature control accuracy deteriorates
Solution Approach 1:
The patent implements a non-contact temperature sensor (thermopile or infrared sensor) that continuously measures the temperature of the workpiece and feeds this information back to the controller. The controller adjusts the induction heating power based on this feedback to maintain the desired set-point temperature, resolving the contradiction between simplified system design and accurate temperature control.
2Measurement precision
If contact-type temperature sensor is used, then temperature measurement accuracy is improved, but interference with outside electronics occurs
Solution Approach 1:
The patent replaces contact-type temperature sensors with non-contact sensors (thermopile or infrared sensors) that measure temperature remotely using thermal radiation detection. This substitution eliminates the need for physical contact between the sensor and workpiece, thereby avoiding interference with external electronics while maintaining temperature measurement capability.
3Stability of the object's composition
If temperature feedback control is implemented, then vapor quality consistency is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback control loop where the non-contact temperature sensor continuously monitors workpiece temperature and the controller adjusts induction heating power accordingly. This feedback mechanism ensures consistent vaporization temperature, improving vapor quality consistency while adding only minimal system complexity through the integration of simple sensor and controller components.
