Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clamshell electronic devices can only switch between a folded and unfolded state, limiting their operational modes to basic on/off states, which restricts their functionality and user experience.
Innovation Solution
An electronic device comprising a first body, a connecting body, and a second body that can rotate relative to each other, allowing for multiple operational modes by adjusting the coverage of display surfaces, enabling more flexible usage scenarios through mode switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device uses only one folded state (folded and unfolded), then the structure is simple, but the operational modes are limited to basic on/off states
Solution Approach 1:
The patent introduces intermediate folded states between the fully folded and fully unfolded positions. The second body can rotate relative to the first body through the connecting body to achieve multiple stable positions (first mode with full coverage, second mode with partial coverage). This dynamic positioning capability transforms a binary state system into a multi-state system, enhancing operational versatility without fundamentally changing the basic folding structure.
Solution Approach 2:
The patent segments the folding motion into distinct intermediate states. Instead of a continuous or binary folding mechanism, the device is designed with specific stopping positions (first mode and second mode) that segment the rotation range. This segmentation allows the device to maintain structural simplicity while providing differentiated operational modes through discrete positional states.
2Adaptability or versatility
If the main display screen is covered in folded state, then the device is compact, but the display functionality is restricted
Solution Approach 1:
The patent uses dynamic positioning of the second body to control display coverage. In the first mode, the second body fully covers the first surface for compact storage. In the second mode, the second body rotates to a intermediate position that partially covers the first surface, exposing a first surface of the connecting body. This dynamic adjustment allows the display functionality to adapt between fully hidden and partially visible states based on operational needs.
Solution Approach 2:
The patent introduces a rotational dimension to the folding mechanism. Instead of simple linear folding, the second body rotates around a hinge axis, creating angular positioning options. This dimensional change enables intermediate coverage states where part of the display remains accessible while maintaining the compact folded form factor, thus resolving the contradiction between compactness and display accessibility.
