Flexible Back End for Hinged Computing Device Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing devices with hinged housings face challenges in providing stable support and ergonomic comfort, especially when transitioning from a closed to an open position, as the rigid structure can lead to instability and discomfort.
Innovation Solution
A case design featuring a base with at least one input device, a display device holder, a hinge coupling the base and the display device holder, and a flexible back end that automatically extends backwardly when the display device holder is opened, thereby increasing the footprint and enhancing stability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid hinged housing structure is used, then structural simplicity is maintained, but stability and ergonomic comfort deteriorate during transition from closed to open position
Solution Approach 1:
The back end is designed to be dynamically adjustable, transitioning from a retracted state in closed position to an extended state in open position. This dynamic extension increases the footprint automatically when needed, providing stability during the transition from closed to open configuration without requiring complex manual adjustment mechanisms.
Solution Approach 2:
The physical parameter of the case footprint is changed by extending the back end. This parameter change occurs automatically in response to the hinge opening, transforming the case from a compact closed form to an extended open form that provides enhanced stability and ergonomic comfort during the transition.
2Ease of operation
If the case footprint is increased for stability, then ergonomic comfort improves, but the device occupies more space when closed
Solution Approach 1:
The back end extends dynamically only when the hinge is in the open position, providing the necessary footprint for ergonomic comfort and stability during use. When the hinge is closed, the back end retracts to minimize the overall footprint, allowing the device to occupy less space during transport or storage.
Solution Approach 2:
The case is segmented into a base portion and an extendable back end portion. This segmentation allows the back end to be independently extended or retracted based on operational needs, providing ergonomic comfort when extended while maintaining compact form when retracted, thus resolving the contradiction between footprint and ergonomics.
3Adaptability or versatility
If a fixed hinge connection is used, then manufacturing simplicity is maintained, but adaptability to different positions and ergonomics deteriorates
Solution Approach 1:
The hinge connection is designed to allow dynamic adjustment of the display device holder's position relative to the base. This dynamic capability enables adaptation to different viewing angles and ergonomic positions while maintaining a relatively simple hinge mechanism that does not require complex actuators or control systems, thus achieving position adaptability without significantly complicating manufacturing.
