Problem
The challenge is to effectively manage the temperature of miniaturized and weight-reduced vehicle wireless communication devices, which experience increased power consumption and heat dissipation difficulties due to their compact size, leading to inadequate thermal management.
Innovation Solution
The device incorporates an electric wave transmission and reception portion, a positioning function, a temperature acquisition component, and a function controller that dynamically represses or restitutes these functions based on temperature thresholds to control heat generation and consumption, ensuring optimal temperature management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the device is miniaturized and weight-reduced, then the device size and weight are improved, but heat dissipation capability deteriorates
Solution Approach 1:
The patent implements dynamic thermal management by continuously monitoring temperature and adaptively controlling power consumption. The control unit adjusts the operating state of communication modules based on real-time temperature feedback, enabling the device to dynamically balance between maintaining communication functionality and controlling heat generation in the compact form factor.
2Volume of moving object
If the device is miniaturized and weight-reduced, then the device size and weight are improved, but power consumption management deteriorates
Solution Approach 1:
The patent applies partial action by selectively activating only the necessary communication functions based on current operational requirements and thermal conditions. The control unit can partially activate communication modules or reduce their power consumption level when full functionality is not needed, thereby managing power consumption effectively in the miniaturized device while maintaining essential operations.
3Adaptability or versatility
If multiple functions are operated simultaneously, then the functionality is improved, but temperature control deteriorates
Solution Approach 1:
The system dynamically adjusts the activation state of different functions based on real-time temperature monitoring. When temperature exceeds thresholds, the control unit selectively deactivates or reduces power to non-critical functions while maintaining essential operations, thereby balancing functionality with thermal control in the compact device.
4Power
If transmission electric power is increased, then communication performance is improved, but heat generation increases
Solution Approach 1:
The patent implements a feedback control mechanism where temperature sensors continuously monitor device temperature and feed this information to the control unit. Based on the temperature feedback, the control unit dynamically adjusts transmission power levels - reducing power when temperature rises and allowing higher power when thermal conditions permit, thereby optimizing communication performance while preventing overheating in the miniaturized device.
