Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices often generate excessive heat during use, leading to uncomfortably high surface temperatures for users, and existing solutions fail to provide adequate control, particularly when audio devices are connected or specific applications are running.
Innovation Solution
Implementing a controller that determines a thermal profile based on the presence and type of audio devices, selected temperature thresholds, application status, and surface temperature, instructing a heat dissipation mechanism to adjust airflow or cooling performance accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the computing device operates at high performance, then processing speed and productivity are improved, but the surface temperature becomes uncomfortably hot for users
Solution Approach 1:
The patent implements dynamic thermal profiles that adjust cooling behavior based on real-time conditions. The controller modifies heat dissipation parameters (such as fan speed or cooling intensity) dynamically according to the detected audio output conditions, allowing the system to adapt cooling performance to current operational needs rather than using fixed cooling levels
Solution Approach 2:
The system changes operational parameters by detecting audio output conditions and selecting from multiple thermal profiles with different temperature thresholds and heat dissipation rates. When audio output is detected, the system transitions to a thermal profile with a lower temperature threshold, thereby changing the temperature parameter to prevent discomfort while maintaining audio quality
2Temperature
If the heat dissipation mechanism operates at high intensity to reduce temperature, then user comfort is improved, but interference with audio output increases
Solution Approach 1:
The patent employs a feedback mechanism where the controller continuously detects audio output conditions and adjusts heat dissipation behavior accordingly. The system monitors for the presence of audio output devices and uses this feedback to determine whether to apply aggressive cooling or to maintain lower cooling intensity, thereby preventing audio interference while managing temperature
Solution Approach 2:
The heat dissipation mechanism transitions from static to dynamic operation, adjusting its intensity based on real-time detection of audio output conditions. The system can switch between different cooling modes (e.g., high-intensity cooling when no audio is detected, reduced-intensity cooling when audio is detected), making the cooling behavior adaptive rather than fixed
3Device complexity
If a fixed temperature threshold is used for heat dissipation, then device control is simplified, but adaptability to different usage scenarios is reduced
Solution Approach 1:
The patent divides the thermal management system into multiple discrete thermal profiles, each with its own temperature threshold and heat dissipation parameters. Instead of using a single fixed threshold, the system segments thermal behavior into distinct modes (e.g., first thermal profile for audio conditions, second thermal profile for non-audio conditions), allowing adaptive selection based on current usage scenarios while maintaining clear, manageable profile definitions
