Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hinge support structure is used for foldable screens, then the structural simplicity is maintained, but manual user intervention is required to adjust the folding angle
Solution Approach 1:
The magnetic assembly automatically adjusts the folding angle of the screen assembly without requiring manual user intervention. The driving apparatus drives the magnetic assembly to rotate along the slide rail, enabling the system to serve itself by automatically transitioning between folded and unfolded states based on operational conditions.
Solution Approach 2:
The patent replaces the traditional manual mechanical hinge operation with an automated driving apparatus that uses magnetic assemblies and slide rails. This substitution eliminates the need for direct mechanical manual manipulation while maintaining the folding functionality through automated actuation.
2Productivity
If manual control is used to adjust folding angle, then the device complexity is low, but the productivity and user convenience are reduced
Solution Approach 1:
The driving mechanism is segmented into distinct functional components: a driving apparatus, a magnetic assembly, and a slide rail. This segmentation allows each component to perform its specific function independently, enabling automated operation while maintaining manageable complexity through modular design.
Solution Approach 2:
The magnetic assembly acts as an intermediary between the driving apparatus and the screen assembly. It translates the driving force from the motor along the slide rail into rotational motion that adjusts the folding angle, thereby enabling automated control without requiring direct complex mechanical linkages between the motor and screens.
3Extent of automation
If automated driving apparatus is introduced, then the extent of automation is improved, but the device complexity increases
Solution Approach 1:
The driving apparatus is designed to perform multiple functions: it drives the magnetic assembly to rotate along the slide rail for folding angle adjustment, and can also maintain the screen assembly in desired positions. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving hands-free operation.
