Incubator Heating Wire Control for Rapid Temperature Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional temperature control methods for incubators, relying on PID algorithms, struggle to rapidly restore internal temperature after the door is opened and closed, leading to adverse effects on microorganism cultivation.
Innovation Solution
A method and device that determine a target heating power based on the set temperature and temperature range, using formulas such as Ptarget=Pmax×(Qn−a×t) and P2nd=Pmax×(Qm−b×t) to control the heating wire, ensuring rapid temperature restoration by mandatory intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If PID algorithm is used to control heating power, then temperature control stability is improved, but temperature restoration speed after door closure deteriorates
Solution Approach 1:
The patent applies dynamics by making the heating control strategy adaptive rather than static. The system dynamically switches between different control modes (PID algorithm for normal operation, mandatory intervention for rapid restoration) based on real-time temperature conditions after door closure, enabling the incubator to optimize both stability and restoration speed across different operational phases
Solution Approach 2:
The patent changes the heating power parameter from passive PID-controlled values to actively mandated high-power levels immediately after door closure. This parameter change enables the system to overcome the slow restoration limitation of PID algorithms by forcing a high-power heating state that rapidly compensates for temperature loss
2Speed
If heating power is increased to restore temperature rapidly, then temperature restoration speed is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by applying mandatory high-power heating intervention only during the critical initial restoration phase after door closure, then transitioning back to normal PID-controlled heating. This time-bound approach ensures rapid temperature restoration while avoiding sustained high energy consumption that would occur with continuous maximum power heating
Solution Approach 2:
The system performs preliminary action by detecting door closure and immediately initiating high-power heating before significant temperature loss occurs. This proactive intervention prevents large temperature deviations, reducing the total energy required for restoration compared to reactive heating after temperature has already dropped
