Solution Overview
Problem
Existing cooling mechanisms for control boards in machines often fail to initiate cooling promptly enough, as they rely on temperature measurements that may not accurately predict heat generation, leading to potential overheating and reduced electronic component lifespan.
Innovation Solution
A predictive cooling mechanism that pre-fetches commands from applications to calculate heat values based on motor operations, electric current values, and machining conditions, allowing for proactive cooler control before temperature increases, eliminating the need for temperature sensors and enabling localized, efficient cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature measurement is used to determine cooling necessity, then the cooling mechanism can be simple to implement, but the cooling may not start in time leading to overheating
Solution Approach 1:
The system performs preliminary actions by pre-fetching application commands and calculating predicted heat values before actual heat generation occurs. The heat value predictor calculates heat values based on pre-fetched commands, and the cooling controller starts cooling operations in advance based on these predictions, ensuring cooling begins before temperature rises beyond safe levels.
2Measurement precision
If temperature sensors are used for monitoring, then the cooling control is simple, but the temperature measurement may not accurately reflect actual heat-generating element temperature
Solution Approach 1:
The system introduces an intermediary approach by using application command analysis as a mediator between the control system and heat generation detection. Instead of directly measuring temperature with sensors, the heat value predictor analyzes application commands to infer heat generation, providing more accurate measurement of actual heat-generating element temperature without relying on temperature sensors that suffer from spatial temperature differences.
3Reliability
If cooling is initiated based on actual machine operative state during a predetermined period, then the control logic is simple, but the temperature inside the control board may already have increased by the time cooling starts
Solution Approach 1:
The system performs preliminary actions by pre-fetching application commands and calculating predicted heat values before actual heat generation occurs. The heat value predictor calculates heat values based on pre-fetched commands, and the cooling controller starts cooling operations in advance based on these predictions, ensuring cooling begins before temperature rises beyond safe levels.
Solution Approach 2:
The system implements feedback by continuously monitoring application commands and adjusting cooling operations based on predicted heat values. The cooling controller receives feedback from the heat value predictor about upcoming heat generation and dynamically adjusts cooler operation timing and intensity, creating a closed-loop control system that responds proactively to thermal conditions.
