Wall-Mounted Computer Workstation With Locking Retractable Tray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Healthcare providers face challenges in ensuring the confidentiality of patient information in public areas, as computer workstations in hospital corridors lack controlled access, making them vulnerable to unauthorized access.
Innovation Solution
A wall-mounted computer workstation with a retractable input device tray and an electronic lock control module that uses electromagnets and non-contacting sensors to securely manage access, automatically closing the tray when not in use and requiring authentication for operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If computer workstations are placed in public areas like hospital corridors for convenient access, then ease of operation is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The input device tray is designed to be dynamically movable between an extended position (for use) and a retracted position (for security). The tray can be quickly extended when needed and automatically or manually retracted when not in use, allowing the system to adapt its accessibility based on operational needs while maintaining security during idle periods.
Solution Approach 2:
The retractable input device tray acts as an intermediary mechanism between the user and the computer system. By controlling access to the keyboard and mouse through the tray's extension and retraction, it mediates between the need for convenient access and the requirement for security, allowing authorized use when extended and preventing unauthorized access when retracted.
2Productivity
If computer terminals are located in public areas for efficient access to information technology, then productivity is improved, but confidentiality of patient information deteriorates
Solution Approach 1:
The dynamic tray mechanism allows the system to maintain high productivity during active use while automatically enhancing security during idle periods. The tray's ability to quickly extend and retract ensures that authorized users can access the system efficiently when needed, while the retracted position prevents unauthorized individuals from viewing or interacting with the computer during breaks or when the authorized user steps away.
Solution Approach 2:
The input device tray serves as a physical intermediary that controls information flow and access. When retracted, it prevents unauthorized eyes from seeing the screen and unauthorized hands from using the input devices, thereby protecting patient information confidentiality. When extended, it enables efficient access for authorized healthcare providers, thus maintaining productivity.
3Object-affected harmful factors
If a retractable input device tray is implemented to prevent unauthorized access, then security is improved, but device complexity increases
Solution Approach 1:
The tray's dynamic design allows it to move between extended and retracted positions using a combination of mechanical components (hinges, sliders, springs) and electromagnetic actuators. This dynamic capability provides enhanced security when retracted while maintaining operational simplicity when extended, as the tray naturally positions itself for use during active periods and automatically secures during idle periods.
Solution Approach 2:
The tray incorporates self-servicing mechanisms including springs that automatically return the tray to the retracted position when not in use, and electromagnets that can automatically extend the tray when a computer is activated. This reduces the need for manual intervention and simplifies operation despite the added mechanical complexity, as the system largely manages itself.

AI summary
Computer workstation includes a mounting bracket for attachment to a wall, and a cabinet connected to the mounting bracket. A track, attached to the cabinet, is engaged with the mounting bracket to vertically guide the cabinet. A non-contacting sensor detects a computer operator. An input device tray is rotatably connected to the cabinet, and has i) an operating position that holds computer input device(s) in an input position and ii) a stowed position substantially preventing access. First electromagnet selectively retains the tray in the stowed position. Second electromagnet selectively retains the tray in the operating position. An electronic lock control panel accepts authentication input from the operator. An electronic lock control module, in a lockable compartment of the cabinet, is connected to the lock control panel and the sensor. The lock control module separately controls electric current flow through the electromagnets in response to authentication by the lock control module.
