Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic device is in a folded state with display on the outside, then the device structure is compact and portable, but the display is prone to friction and collision with external objects
Solution Approach 1:
The patent inverts the conventional outward-folding design by implementing an inward-folding structure where the display is positioned inside the device body when folded. This reversal of the folding direction protects the display from external contact while maintaining portability, directly resolving the contradiction between compactness and display protection
2Device complexity
If the display is positioned on the outside in folded state, then the device structure is simplified, but the service life of the display is severely shortened
Solution Approach 1:
By inverting the folding direction to position the display internally rather than externally, the patent achieves both simplified structure and extended display service life. The inward-folding mechanism naturally protects the display without requiring complex additional protective structures
3Object-affected harmful factors
If the floating support component is moved away from the base, then the display is protected from collision, but the structural stability is reduced
Solution Approach 1:
The patent employs dynamic elastic reset members that allow the floating support component to move away from the base during folding operations to protect the display, then automatically return to the original position to maintain structural stability. This dynamic adjustment resolves the contradiction between collision protection and structural stability
4Object-affected harmful factors
If the hinge mechanism allows movement of the floating support component, then the display can avoid friction, but the mechanism complexity increases
Solution Approach 1:
The hinge mechanism incorporates dynamic elements including rotatable components and elastic reset members that enable the floating support component to move and return automatically. This dynamic design protects the display from friction while maintaining reasonable mechanism complexity through efficient use of elastic energy storage and release

AI summary
This application discloses a hinge mechanism and an electronic device, and belongs to the field of communication devices. The hinge mechanism includes a base, first rotating components, second rotating components, a first connecting component, a second connecting component, a floating support component, and elastic reset members. In a case that the hinge mechanism is in a first state, the first connecting component is on one side of the base, and the second connecting component is on the other side of the base. At least one of the plurality of the second rotating components supports the floating support component, and the elastic reset members are in a stretched or compressed state to squeeze the floating support component and the second rotating components. A distance between an outer wall that is of the base and that faces away from a rotation axis of the first rotating component and the floating support component is a first distance. In a case that the hinge mechanism is in a second state, both the first connecting component and the second connecting component are on a side that is of the base and that faces the rotation axis of the first rotating component, the second rotating components avoid the floating support component, a distance between the outer wall of the base and the floating support component is a second distance, and the second distance is less than the first distance.
