Problem
Users face difficulties in conveniently controlling laptop computers with touchscreen or keyboard inputs while holding the device, particularly in adjusting the folding angle, which can lead to reduced usability and increased risk of dropping the device.
Innovation Solution
An electronic device with a processor that identifies inputs from a plurality of keys and adjusts functions of a camera application based on the folding angle between the device's housings, allowing for efficient operation within a designated angle range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user controls the laptop computer using the touchscreen or keyboard while holding the device, then the device provides portability and functionality, but the user convenience is reduced and the risk of dropping the device increases
Solution Approach 1:
The patent applies dynamics by making the keyboard rotatable relative to the touchscreen, allowing the keyboard to be positioned at different angles including perpendicular to the touchscreen. This enables the user to hold the device securely with one hand while comfortably typing on the keyboard with the other hand, thereby improving ease of operation without increasing the risk of dropping the device.
2Adaptability or versatility
If the folding angle between housings is changed to various angles, then the device provides adaptability for different usage scenarios, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the device into two main housings (first housing with touchscreen and second housing with keyboard) connected by a hinge. This segmentation allows each housing to be independently positioned at different angles, providing adaptability for various usage scenarios while keeping the overall structure relatively simple and manageable.
3Ease of operation
If the keyboard is positioned on the same plane as the touchscreen, then the device structure is simple, but the user cannot comfortably type while holding the device
Solution Approach 1:
The patent applies dynamics by making the keyboard rotatable relative to the touchscreen, allowing the keyboard to be positioned at different angles including perpendicular to the touchscreen. This enables the user to hold the device securely with one hand while comfortably typing on the keyboard with the other hand, thereby improving ease of operation without increasing the risk of dropping the device.
