Wall-Mounted Rotatable Shelf for Space-Efficient Keyboard Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical environments, particularly dental operating rooms, there is a need for efficient storage and use of office equipment like keyboards due to limited space and ergonomic considerations, as existing solutions fail to provide adequate space-saving and ergonomic solutions.
Innovation Solution
An adjustable shelf with a wall mount that includes a rotatable tray, allowing it to switch between an operational orientation for supporting objects and a storage orientation where it is parallel to the wall, minimizing space usage, equipped with a locking mechanism for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shelf is designed to support working materials and computer accessories, then the workspace functionality is improved, but the space occupied when not in use increases
Solution Approach 1:
The shelf employs a rotatable shaft that allows the tray to rotate between a horizontal operational orientation for workspace functionality and a vertical storage orientation to minimize space occupation. This dynamic reconfiguration enables the same structure to serve dual purposes at different times.
Solution Approach 2:
The shelf transitions from occupying horizontal space when in use to occupying vertical space when stored, effectively changing the dimension in which it occupies space. This allows the workspace to be reclaimed when the shelf is not needed.
2Area of stationary object
If the shelf is designed for low profile storage, then the space efficiency is improved, but the ergonomic positioning capability is reduced
Solution Approach 1:
The rotatable shaft mechanism enables the tray to dynamically adjust between a low-profile vertical storage position for space efficiency and a horizontal operational position for ergonomic workspace functionality, resolving the contradiction between these two requirements.
3Stability of the object's composition
If the shelf includes a locking assembly for fixed positioning, then the stability is improved, but the device complexity increases
Solution Approach 1:
The locking assembly utilizes spring-loaded buttons that automatically engage with slots at predetermined positions to provide stable locking without requiring external actuators or complex control mechanisms. The system self-locks when the shaft reaches predetermined angles.

AI summary
An adjustable shelf includes a wall mount for coupling to a wall. A fixed post extends downwardly from the wall mount along a first axis. A post assembly has a rotatable tube coupled to the fixed post so that the rotatable tube rotates about the first axis. An arm extends from the rotatable tube along a second axis substantially perpendicular to the first axis. A shaft rotatably couples within the arm and extends from the arm along the second axis, the shaft being rotatable about the second axis between an operational orientation and a storage orientation. A tray extends from the shaft for holding a keyboard. In the storage orientation, the tray is substantially parallel to the wall and, in the operational orientation, the tray is at an angle with respect to the wall. A locking assembly selectively fixes the tray in the operational orientation and the storage orientation.
