Solution Overview
Problem
Existing electronic apparatuses lack effective mechanisms to remind users of their operational states, such as folded or unfolded positions, which can lead to misuse and potential damage, and do not efficiently manage battery power for optimal user interaction and device longevity.
Innovation Solution
An electronic apparatus with a rotatable casing, a sensor to detect the angle between shells, a processor to compare the actual angle with a target angle, and a reminding device (like a vibrating or sounding mechanism) to output alerts when the device is in specific states, optimizing user interaction and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a foldable screen design is implemented to increase screen size and improve portability, then the device provides larger display area and better portability, but the device lacks mechanisms to remind users of operational states which can lead to misuse and potential damage
Solution Approach 1:
The patent implements a feedback mechanism where the sensor detects the actual angle between the first shell and second shell, compares it with the target angle, and triggers a reminding device to provide tactile or audible feedback to the user. This closed-loop feedback system informs users of the device's operational state, preventing misuse and potential damage while maintaining the foldable design's portability benefits.
2Area of moving object
If the screen size is increased through foldable design, then entertainment requirements are met, but the device complexity increases with additional sensors, processors, and reminding mechanisms
Solution Approach 1:
The reminding device is designed to serve multiple functions: it provides tactile feedback through vibration, can emit audible warnings, and operates across different device states (folded, unfolded, partially folded). This multi-functionality reduces the need for separate components for different alert types, thereby managing device complexity while maintaining large screen capabilities.
3Ease of operation
If reminding devices such as vibrating or sounding mechanisms are added to indicate operational states, then user interaction is enhanced, but power consumption increases which affects battery life
Solution Approach 1:
The reminding device operates periodically or on-demand based on detected operational state changes rather than continuously. The processor compares the actual angle with the target angle and only triggers the reminding device when a state change is detected, thereby enhancing user interaction while minimizing power consumption and preserving battery life.
4Loss of information
If the device provides continuous feedback on operational states, then user awareness is improved, but battery power is depleted faster reducing device longevity
Solution Approach 1:
The system performs preliminary angle comparison and state detection before triggering the reminding device. By using the sensor to detect the actual angle and the processor to compare it with the target angle in advance, the system only activates the reminding device when necessary, thereby maintaining user awareness while conserving battery power for longer device longevity.
