Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple hinge structure is used, then the device complexity is reduced, but the ability to maintain stable angles during folding or unfolding is lost
Solution Approach 1:
The hinge structure is segmented into multiple independent rotation axes (first rotation axis and second rotation axis) that can rotate independently. This segmentation allows each axis to control a specific folding angle, enabling the device to maintain multiple stable angles simultaneously while keeping the overall structure relatively simple and modular.
2Stability of the object's composition
If multiple rotation axes are added to enable angle control, then the angle stability is improved, but the device complexity increases
Solution Approach 1:
Multiple rotation axes and their supporting members are merged into a single integrated hinge assembly that is connected to the display module as one unit. This merging approach allows the complex angle control functionality to be achieved while presenting a unified, manageable structure that simplifies installation and maintenance.
3Ease of operation
If the hinge allows free rotation, then the ease of operation is improved, but the ability to maintain specific angles is lost
Solution Approach 1:
The hinge structure dynamically transitions between two states: during operation, the rotation axes allow free movement for easy folding and unfolding; during rest, the friction torque generated by the rotation axes naturally maintains the device at specific angles. This dynamic behavior provides both ease of operation and angle maintenance without requiring additional active control mechanisms.
