Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer systems face challenges in maintaining temperature below critical thresholds while balancing high computing power, compactness, and battery performance, as traditional designs fail to adjust thermal requirements dynamically in response to changing conditions such as location and usage.
Innovation Solution
The system detects conditions like motion and location using accelerometers and adjusts thermal requirements by setting temperature points and throttling performance to maintain temperatures within safe limits, allowing for optimal performance and user satisfaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the critical temperature threshold is set high to provide better performance, then computing power is improved, but the cooling experience deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of the critical temperature threshold based on detected motion conditions. The threshold is no longer fixed but adapts in real-time: set to a first (lower) threshold when motion is detected and a second (higher) threshold when no motion is detected, resolving the contradiction by making the temperature parameter dynamic rather than static
Solution Approach 2:
The system uses motion detection feedback to continuously adjust the critical temperature threshold. The motion detection unit provides feedback about user presence, and the control unit uses this feedback to automatically select appropriate temperature thresholds, creating a closed-loop control system that balances performance and cooling experience
2Object-affected harmful factors
If the critical temperature threshold is set low to provide better cooling experience, then cooling experience is improved, but performance deteriorates
Solution Approach 1:
The system dynamically adjusts the critical temperature threshold based on motion detection. When no motion is detected (indicating the device is stationary and likely on a surface), the threshold is set higher to maximize performance. When motion is detected (indicating the device may be on a user's lap), the threshold is set lower to prioritize cooling experience
Solution Approach 2:
Motion detection feedback enables automatic selection of appropriate temperature thresholds. The system monitors for motion continuously and adjusts the thermal management strategy accordingly, allowing high performance during stationary operation while ensuring user comfort during portable use
3Adaptability or versatility
If the system continuously monitors motion conditions to dynamically adjust thermal requirements, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system performs self-adjustment of thermal requirements based on automatic motion detection. The control unit autonomously selects appropriate temperature thresholds without user intervention, and the motion detection unit automatically provides the necessary input data, enabling the system to manage its own thermal conditions adaptively
Solution Approach 2:
The motion detection unit serves multiple functions: it detects motion for thermal management purposes while also potentially serving other system functions. This multi-functionality reduces the need for dedicated components solely for thermal adaptation, thereby limiting the increase in device complexity

AI summary
Methods and apparatuses to automatically adjust a thermal requirement of a data processing system are described. One or more conditions associated with a data processing system are detected. A temperature requirement for the data processing system is determined based on the one or more conditions. The performance of the data processing system may be throttled to maintain a temperature of the data processing system below the temperature requirement. Detecting the one or more conditions associated with the data processing system may include determining a location of the data processing system based on a measured motion, a state of a peripheral device, a position of one portion of the data processing system (e.g., a lid) relative another portion of the data processing system (e.g., a bottom portion), a type of application operating on the data processing system, or any combination thereof.
