Solution Overview
Problem
Thermal management systems face challenges in efficiently managing temperature limits across components, leading to premature operation restrictions due to fixed thermal resistance and capacity, which can result in reduced performance and increased costs.

A controller adjusts the thermal resistance and capacity of a medium between components to delay the reaching of temperature limits, extending operational duration by dynamically managing thermal margins and resistance based on temperature differences and limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If fixed thermal resistance and capacity are used in thermal management systems, then the system structure is simple, but the operational duration is reduced due to premature temperature limit reaching
Solution Approach 1:
The patent applies dynamics by making the thermal resistance and thermal capacity adjustable rather than fixed. The controller dynamically modifies these parameters based on real-time temperature monitoring of multiple components, allowing the thermal management system to adapt its behavior to changing thermal conditions and extend operational duration before temperature limits are reached.
Solution Approach 2:
The patent implements parameter changes by varying the thermal resistance and thermal capacity values according to the thermal states of different components. The controller adjusts these parameters based on temperature differences and thermal margins, enabling the system to optimize heat transfer paths and delay temperature limit reaching, thereby extending operational duration.
2Duration of action of moving object
If additional cooling components are added to extend operational duration, then the operational duration is improved, but the manufacturing cost increases
Solution Approach 1:
The patent uses parameter changes to adjust thermal resistance and capacity values through control signals, eliminating the need for additional physical cooling components. By dynamically modifying these thermal parameters based on component temperature states, the system extends operational duration using software/control-based solutions rather than hardware additions, thereby reducing manufacturing costs.
Solution Approach 2:
The patent replaces mechanical/physical cooling components with a control-based thermal management approach. Instead of adding more heat sinks, fans, or thermal interface materials, the system uses a controller to adjust thermal parameters electronically, substituting a mechanical solution with a control-system solution that reduces manufacturing complexity and cost.
3Productivity
If fixed thermal resistance is used, then the device complexity is low, but the performance is reduced due to premature operation restrictions
Solution Approach 1:
The patent applies dynamics by implementing adjustable thermal resistance that responds to real-time temperature conditions. The controller continuously monitors component temperatures and dynamically modifies thermal resistance values to optimize heat transfer, allowing the system to maintain higher performance levels for longer periods without premature operation restrictions, despite the increased control complexity.
Solution Approach 2:
The patent implements feedback by using temperature sensor data from multiple components to control the adjustment of thermal resistance. The controller receives temperature information, compares it against thermal margins and limits, and adjusts thermal resistance accordingly, creating a closed-loop system that optimizes performance while preventing temperature limit violations.
