Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices, such as laptops, struggle to detect when they are placed in enclosed spaces, leading to restricted airflow, which can cause elevated operating temperatures and inefficient performance, as existing technologies fail to accurately determine such environments in real-time.
Innovation Solution
A system comprising a processor, sensor, and memory that measures parameters like airflow rate, air temperature, or current supply at the inlet of a computing device, sending a signal when these parameters reach a calibrated threshold, indicating the device is in an enclosed space, thereby adjusting power to maintain safe operating temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the computing device operates in an enclosed space without detection, then the device structure remains simple, but the operating temperature increases and performance becomes inefficient
Solution Approach 1:
The patent combines multiple sensing capabilities (airflow detection, temperature sensing, power consumption monitoring) into an integrated detection system that works together to identify enclosed space conditions. This merging approach enables comprehensive environmental awareness without proportionally increasing device complexity, as the sensors share common processing infrastructure and work synergistically to solve the thermal management problem.
Solution Approach 2:
The detection system is designed to perform multiple functions: detecting airflow restrictions, measuring temperature, monitoring power consumption, and determining overall environmental suitability. This multi-functionality allows a single integrated system to address various aspects of thermal management and performance optimization simultaneously, reducing the need for separate dedicated sensors for each parameter.
2Productivity
If real-time environmental monitoring is implemented, then performance efficiency is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic sampling of environmental parameters rather than continuous monitoring. The processor periodically reads sensor data and evaluates environmental conditions, adjusting the monitoring frequency based on operational state and detected changes. This periodic approach maintains performance efficiency through timely detection while reducing overall energy consumption compared to continuous real-time monitoring.
Solution Approach 2:
The system dynamically adjusts monitoring parameters such as sampling frequency and threshold sensitivity based on operational context. When the device detects stable environmental conditions, it reduces monitoring intensity to conserve energy. When changes are detected or performance degradation is imminent, the system increases monitoring frequency, thereby optimizing the balance between productivity and energy consumption.
3Reliability
If the device adjusts power consumption to prevent overheating, then operating safety is improved, but available power for operations is reduced
Solution Approach 1:
The system dynamically adjusts power consumption levels based on real-time environmental conditions and thermal state. Rather than using fixed power reduction, the processor adapts power management strategies according to the degree of enclosure, ambient temperature, and current thermal load. This dynamic approach maintains operating safety by preventing overheating while maximizing available power within safe thermal boundaries.
Solution Approach 2:
The system implements closed-loop feedback control where sensor data about temperature, airflow, and power consumption continuously informs power management decisions. The processor monitors thermal conditions and adjusts power allocation accordingly, reducing power when thermal thresholds are approached and allowing higher power consumption when conditions permit. This feedback mechanism ensures operating safety while optimizing available power for computational operations.

AI summary
Apparatuses, methods, systems, and program products are disclosed to determine when a portable electronic device is moved within an enclosed space. A processor and memory may control a sensor may store code executable by the processor to measure a parameter at an inlet of the computing device. The parameter may include an airflow rate, an air temperature at the inlet, and/or a current supply to a fan of the computing device. The processor may execute code to determine when the parameter at the inlet reaches a threshold. When the processor determines that the measured parameter has reached the threshold, a signal from the sensor to the processor and/or from the processor to an operator may be sent, indicating that the threshold has been reached.
