Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication base station systems face instability and increased costs due to the use of industrial standard components that require separate temperature control devices, leading to oscillating or repeated turn-on/off operations when internal temperatures vary around the base temperature.
Innovation Solution
A method and device utilizing a hysteresis circuit to set temperature control settings for starting and stopping temperature control operations, ensuring stable operation by differentiating between a first base temperature for initiating and a second base temperature for terminating the temperature control device, thereby preventing oscillations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If industrial standard components are used to ensure operation at -40°C, then the system can operate in extreme temperature ranges, but the cost increases
Solution Approach 1:
The patent changes the temperature parameter threshold by introducing hysteresis control with two distinct temperature thresholds: a first base temperature for starting operation and a second base temperature for stopping operation. This parameter differentiation allows the system to use standard components while maintaining reliable operation across extreme temperature ranges by preventing oscillatory behavior near the threshold.
2Device complexity
If a single base temperature is used for temperature control, then the control logic is simple, but the system generates oscillating turn-on/off operations when temperature varies around the base temperature
Solution Approach 1:
The patent segments the temperature control into two distinct operational thresholds: a first base temperature for initiating operation and a second base temperature for terminating operation. This segmentation of the control parameter prevents the oscillating turn-on/off behavior that occurs with a single threshold by creating a hysteresis gap between the two temperatures.
Solution Approach 2:
The patent applies beforehand cushioning by establishing a temperature buffer zone between the first and second base temperatures. This cushioning prevents the system from rapidly switching on and off when the temperature fluctuates near a single threshold, as the hysteresis gap provides a buffer that absorbs temperature variations without triggering immediate state changes.
3Ease of manufacture
If standard components operating at a specific base temperature are used, then cost is reduced, but the system requires separate temperature control devices and cold start procedures
Solution Approach 1:
The patent enables the temperature control device to regulate its own operation through hysteresis-based autonomous control. The system automatically determines when to start and stop based on comparing the current temperature against the first and second base temperatures, eliminating the need for external cold start procedures and reducing overall system complexity despite using standard components.

AI summary
A system and method are provided for controlling a temperature of a communication base station system or similar device. The method includes collecting temperature information from at least one location in a system such as a base station, setting hysteresis-based temperature settings for a first base temperature for starting to operate a temperature control device in the base station, and a second base temperature for terminating operation of the temperature control device based on the collected temperature information, generating temperature control information by comparing the set hysteresis-based temperature and the collected temperature information, and controlling the temperature control device and/or power to the base station by using the temperature control information.
