Keyboard Supporting Leg Pivotal Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keyboard devices with supporting legs have an aesthetically unpleasing appearance due to the need for a finger-receiving recess to facilitate leg deployment, which creates a 'broken hole' effect when the leg is stored.
Innovation Solution
A keyboard device design where the supporting leg is pivotally coupled to an inner accommodation space, switching between stored and supporting states without requiring a finger-receiving recess, with the leg being accommodated entirely within the space when stored, utilizing a first and second supporting part and a pivotal shaft to maintain a flat appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a finger-receiving recess is provided to facilitate supporting leg deployment, then ease of operation is improved, but appearance quality deteriorates due to the broken hole effect
Solution Approach 1:
The invention extracts the finger-receiving recess from the external surface and relocates it to the inner surface of the casing. This allows the supporting leg to be deployed by pressing from the inside, eliminating the visible broken hole effect on the external appearance while maintaining the functionality of easy leg deployment.
Solution Approach 2:
Instead of providing a recess on the outer surface for finger insertion, the invention inverts the approach by providing the recess on the inner surface. The supporting leg is deployed by pressing from the inside outward, reversing the traditional interaction direction and solving the appearance problem.
2Volume of moving object
If the supporting leg is stored in the accommodation space, then device compactness is improved, but appearance quality deteriorates due to the visible recess
Solution Approach 1:
The invention extracts the finger-receiving recess from the external viewable surface and relocates it to the inner surface of the casing. This allows the supporting leg to be stored compactly in the accommodation space without creating a visible broken hole effect on the external appearance.
3Ease of operation
If the supporting leg is pivotally coupled to the bottom side, then ease of operation is improved for tilt adjustment, but device complexity increases due to additional structural components
Solution Approach 1:
The invention merges the pivot shaft and the supporting leg into a more integrated structure. The pivot shaft is positioned at the inner portion of the accommodation space, and the supporting leg is directly coupled to it, simplifying the overall structure while maintaining the ease of tilt adjustment functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design allows for adjustable tilt and improved aesthetics by eliminating the need for an external finger-receiving recess, resulting in a more aesthetically pleasing appearance and simplified leg deployment mechanism.
Implementation Method 1
The pivotal shaft is rotatable relative to the casing. Consequently, the supporting leg is permitted to be switched between a stored state and a supporting state.

AI summary
A keyboard device includes a casing and at least one supporting leg. The supporting leg includes a first supporting part, a second supporting part and a pivotal shaft. The supporting leg is pivotally coupled to an accommodation space of the casing through the pivotal shaft. The pivotal shaft is rotatable relative to the casing. Consequently, the supporting leg can be switched between a stored state and a supporting state. When the supporting leg is in the stored state, the supporting leg is accommodated within the accommodation space, and the accommodation space is covered by the first supporting part and the second supporting part. While the supporting leg is switched from the stored state to the supporting state, the first supporting part is pushed into the accommodation space in response to an external force, and the second supporting part is correspondingly moved away from the accommodation space.
