Dual-Axis Hinge Assembly for 360° Rotation Without Body Recesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinge structures for dual-body electronic devices, such as notebook computers, often result in a compromised appearance due to the formation of depressions on the bodies where the hinge is located, and they lack the ability to rotate freely at 360 degrees while maintaining a complete aesthetic.
Innovation Solution
A dual-axis hinge assembly that includes a first and second rotating shaft, torque components, rotating shaft sleeve, brackets, and cable sleeves, allowing for 360-degree rotation and forming two cylindrical structures side by side when exposed, thus maintaining a complete appearance of the device bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional hinge structure is used to connect two bodies, then the hinge allows relative pivoting between the bodies, but the hinge structure creates a depression on the device bodies resulting in compromised appearance
Solution Approach 1:
The hinge assembly is extracted from the traditional embedded configuration and repositioned to extend outward from the device bodies. The rotating shafts and brackets are positioned such that they protrude from the first and second bodies, eliminating the need for depressions in the device shells. This extraction allows the hinge to function while maintaining the complete, smooth appearance of the device bodies.
Solution Approach 2:
The hinge assembly transitions from a planar, embedded configuration to a three-dimensional, extended configuration. By positioning the rotating shafts and brackets to extend outward in multiple dimensions, the hinge achieves pivoting functionality without requiring recesses in the device bodies, thus resolving the contradiction between operational capability and aesthetic appearance.
2Shape
If a hinge structure is embedded within device bodies, then the appearance is maintained, but the hinge cannot rotate freely at 360 degrees
Solution Approach 1:
The hinge assembly is extracted from the embedded configuration and repositioned to extend outward from the device bodies. This extraction provides the necessary space for the rotating shafts and brackets to achieve full 360-degree rotation while maintaining the complete appearance of the device bodies, as the hinge components are positioned externally rather than within recesses.
Solution Approach 2:
The hinge assembly is designed with dynamic positioning capabilities, allowing the rotating shafts and brackets to move freely through a 360-degree range. The first and second brackets are connected to the rotating shafts in a manner that enables continuous rotation, providing adaptability and versatility while the external positioning maintains aesthetic appearance.
3Adaptability or versatility
If the hinge assembly is positioned externally to allow 360-degree rotation, then rotation freedom is achieved, but the device appearance may be compromised
Solution Approach 1:
The hinge assembly components, including the rotating shafts, brackets, and protective sleeves, are merged into a unified, integrated structure. This merging creates a cohesive design where the external positioning of the hinge does not compromise aesthetics, as the components work together to form a visually coordinated assembly that maintains device appearance while enabling 360-degree rotation.
Solution Approach 2:
The hinge assembly incorporates curved and cylindrical elements, such as the rotating shafts and protective sleeves, that create a smooth, aesthetically pleasing appearance. The curved design of the external hinge components blends with the device form factor, allowing 360-degree rotation freedom while maintaining or enhancing device aesthetics rather than compromising them.
