Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature sensor is used to detect flame temperature for controlling the heating device, then the control precision is improved, but the response time becomes slow due to the thermal mass of the sensor
Solution Approach 1:
The temperature sensor is pre-heated to a target temperature before actual measurement begins. This preliminary heating action reduces the thermal mass effect during measurement, allowing the sensor to respond faster to temperature changes while maintaining measurement precision. The sensor is heated by applying electrical power to it before and during the measurement process.
2Stability of the object's composition
If the power adjustment rate is reduced to accommodate slow temperature measurement response, then measurement stability is improved, but user comfort and operational reliability deteriorate
Solution Approach 1:
By pre-heating the temperature sensor to its target temperature, the system achieves stable measurements without needing to reduce the power adjustment rate. The preliminary heating ensures the sensor is already at operational temperature, providing stable readings while allowing the control system to respond quickly to user demands.
Solution Approach 2:
The system changes the temperature parameter of the sensor by actively heating it to a target temperature. This parameter change enables the sensor to operate in an optimal temperature range where it provides stable measurements while maintaining fast response capability, thus improving user comfort without sacrificing measurement stability.
3Stability of the object's composition
If the power adjustment rate is reduced to accommodate slow temperature measurement response, then measurement stability is improved, but detection of critical conditions is delayed
Solution Approach 1:
The temperature sensor is pre-heated to target temperature before measurement, enabling it to detect critical conditions immediately. This preliminary action ensures the sensor is ready to provide stable and reliable measurements from the start, allowing prompt detection of critical states such as flame extinction without delaying safety responses.
4Speed
If an actively heated temperature sensor is used, then response speed is improved, but device complexity increases
Solution Approach 1:
The temperature sensor serves multiple functions: it acts as both the measurement device and the heating element. By applying electrical power directly to the temperature sensor, it functions as a self-heating device, eliminating the need for a separate heating element and reducing overall device complexity while maintaining fast response speed.
Solution Approach 2:
The temperature sensor heats itself by applying electrical power to it, rather than requiring an external heating system. This self-service approach simplifies the device architecture by eliminating separate heating components and control systems, reducing complexity while achieving the desired fast response performance.
