Solution Overview
Problem
Conventional cooling devices for in-vehicle devices respond slowly to external temperature changes, leading to insufficient cooling and increased energy consumption due to feedback control mechanisms.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If feedback control is used to perform cooling based on current temperature detected by temperature sensor, then cooling control is simple to implement, but response to external temperature factors is late and sufficient cooling cannot be performed
Solution Approach 1:
The control device performs preliminary cooling actions by detecting external temperature factors (ambient temperature, sunlight intensity, vehicle speed) and predicting future temperature changes before they affect the in-vehicle device. The controller activates the cooling device in advance based on predicted temperature rise, rather than waiting for feedback from temperature sensors. This preliminary action resolves the contradiction by achieving fast response to external factors without requiring complex real-time feedback control systems.
2Use of energy by stationary object
If cooling is performed after temperature changes are reflected in the object to be cooled, then control is simple, but cooling is delayed and requires higher power
Solution Approach 1:
The system performs preliminary cooling by predicting temperature changes based on external factors before the in-vehicle device temperature actually rises. The controller calculates predicted temperature changes and activates cooling in advance, preventing temperature rise rather than correcting it afterward. This approach reduces both cooling delay time and power consumption by avoiding the need for high-power corrective cooling.
Solution Approach 2:
The control device applies preliminary anti-action by counteracting external heating factors (sunlight, high ambient temperature, vehicle speed effects) before they cause temperature rise in the in-vehicle device. The controller detects these external factors and activates cooling to preemptively counteract their heating effect, resolving the contradiction between response time and energy consumption.
3Reliability
If cooling device maintains capability of in-vehicle device during large temperature changes, then device reliability is improved, but cooling requires higher power
Solution Approach 1:
The control device maintains reliability during large temperature changes by performing preliminary cooling actions based on predicted temperature changes from external factors. Instead of allowing temperature to rise and then applying high-power cooling, the system preemptively activates cooling at lower power levels, maintaining device capability while reducing energy consumption.
