Solution Overview
Problem
Information handling systems, particularly handheld devices, face challenges in efficiently configuring their operation based on varying power sources, docking states, and user interactions, leading to suboptimal performance and power consumption.
Innovation Solution
A method and system that utilize an embedded controller to determine the device's state, such as being docked, connected to a power supply, or operating on battery power, and adjust the device's configuration to operate in specific modes like Ultra Performance, Optimized, Quiet, or Peak Mode by managing graphics processing units, core performance levels, and thermal management based on these states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the handheld device operates in high performance mode continuously, then processing speed is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts performance modes based on real-time detection of user interactions (button presses, touchscreen inputs, accelerometer data) and environmental conditions (temperature sensors). The device transitions between performance modes, power-saving modes, and thermal management modes rather than operating statically at high performance continuously.
Solution Approach 2:
The system changes operational parameters by adjusting CPU frequency, GPU clock speeds, and power delivery levels based on detected conditions. When high performance is needed, the system increases power delivery to the processor and graphics unit; when performance is not critical, it reduces power consumption by lowering operational frequencies and disabling non-essential functions.
2Productivity
If the device delivers high performance continuously, then productivity is improved, but thermal management becomes difficult
Solution Approach 1:
The system implements periodic thermal management cycles where it monitors temperature sensors and alternates between high-performance operation and thermal throttling. When temperature thresholds are exceeded, the system reduces processor frequency and power delivery to allow cooling, then restores performance when temperatures return to acceptable ranges.
Solution Approach 2:
The system proactively manages thermal conditions by detecting temperature trends before critical thresholds are reached. It preemptively reduces performance or activates cooling mechanisms (such as reducing fan speed or disabling high-power components) to prevent thermal runaway, rather than waiting for overheating to occur.
3Adaptability or versatility
If the device adapts to multiple operating states, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system automatically detects its own operating conditions through integrated sensors (accelerometer, temperature sensors, power state detection) and self-configures appropriate performance modes without user intervention. The embedded controller monitors button presses, touchscreen activity, and environmental conditions, then autonomously adjusts power delivery and processor frequencies accordingly.
Solution Approach 2:
The system uses a single integrated controller that handles multiple functions: detecting user interactions, monitoring environmental conditions, managing power delivery, and controlling thermal management. This multi-functional approach consolidates what would otherwise require separate dedicated systems, reducing overall complexity while maintaining adaptability across diverse operating states.

AI summary
A system for configuring a handheld device based on a state of the handheld device includes an embedded controller (EC), a provided service, user selectable thermal tables (USTT), an Operating System (OS) scheduler, a power plan management (PPM) service and a thermal management service (TMS). The provided service communicates with the EC to determine if the handheld device is docked or coupled to a power supply, is stationary or moving, is coupled to an external display and whether a Peak Mode button is activated and communicates signals to one or more of the USTT, the OS scheduler, the PPM and the TMS to configure the handheld device in one of an Ultra Performance Mode, an Optimized Mode, a Quiet Mode or a Peak Mode.
