Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with foldable displays often fail to adjust their operation modes correctly when transitioning from a table-based usage to being gripped by a user, leading to inconvenience in user experience.
Innovation Solution
The electronic device is designed to detect changes in placement states, such as from a table to being gripped, and automatically switch to appropriate operation modes by utilizing sensors to determine the angle and placement state, allowing it to adjust settings like touch sensitivity and vibration accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic device operates in a fixed operation mode regardless of placement state changes, then the device structure remains simple, but the user experience deteriorates due to inappropriate operation modes during state transitions
Solution Approach 1:
The patent implements dynamic operation mode switching based on real-time detection of placement state changes. The processor continuously monitors sensor data (acceleration, gyroscope) to detect transitions between table placement and hand gripping states, and automatically switches operation modes accordingly. This dynamic adaptation resolves the contradiction by making the system responsive to user needs without requiring complex manual intervention.
Solution Approach 2:
The patent employs feedback mechanisms where sensors continuously monitor the placement state and provide real-time information to the processor. The system uses acceleration sensors and gyroscope data to detect placement state changes, processes this feedback information, and adjusts operation modes based on the detected state. This closed-loop feedback system enables automatic adaptation while maintaining relatively simple device architecture.
2Measurement precision
If the device uses multiple sensors to detect placement state changes, then the detection accuracy improves, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple sensor types (acceleration sensor and gyroscope) into an integrated sensor system that works together to detect placement state changes. By merging these sensors and processing their combined data through algorithms that analyze both linear acceleration and rotational motion, the system achieves high detection accuracy while managing complexity through unified sensor management and coordinated data processing.
3Ease of operation
If the device automatically switches operation modes based on placement state, then the usability improves, but the risk of erroneous mode switching increases
Solution Approach 1:
The patent implements preliminary detection and confirmation mechanisms before switching operation modes. The system continuously monitors sensor data and identifies trends in placement state changes, using predictive algorithms to anticipate user intent. By analyzing patterns in acceleration and gyroscope data over time, the system can distinguish between intentional placement changes and transient movements, reducing erroneous mode switching while maintaining responsive usability.
