Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack the ability to detect a pick-up state, such as being lifted by a user, which limits the customization of power state transitions and hinders improvements in user experience, battery duration, energy conservation, and heat management.
Innovation Solution
The device employs a multi-sensor system, including an accelerometer, to detect a pick-up state by analyzing acceleration along multiple axes, using different algorithms based on the orientation and lid status of the device, allowing it to transition between power states proactively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device uses a single algorithm to detect pick-up state, then the detection logic is simple, but it cannot accurately detect pick-up state across different operation modes (clamshell, closed, tablet, tent, stand modes)
Solution Approach 1:
The patent divides the pick-up detection function into multiple operation mode-specific algorithms. Each algorithm (first algorithm for closed/tablet modes, second algorithm for clamshell/tent/stand modes) is segmented to handle specific mode characteristics, enabling accurate detection across all modes while keeping each individual algorithm relatively simple
2Use of energy by moving object
If the device transitions between power states proactively based on pick-up detection, then user experience and energy efficiency are improved, but the device requires additional sensors and processing capability
Solution Approach 1:
The device performs preliminary pick-up detection using accelerometer data before actually transitioning power states. By detecting the pick-up state in advance and then proactively transitioning to appropriate power states, the system optimizes energy usage without requiring complex real-time processing during the actual state change
Solution Approach 2:
The device uses its existing accelerometer sensor and processing capabilities to autonomously detect pick-up states and trigger power state transitions without requiring external input or additional complex processing systems. The device serves itself by leveraging already-present components

AI summary
The present disclosure is directed to pick-up state detection for an electronic device, such as a laptop. In a pick-up state, the device is picked or lifted up from a surface, such as a table. A power state of the device is adjusted in response to detecting the pick-up state. For example, the device is in a hibernate state while set on the table, and is switched to a working state in response to detecting the pick-up state.
