Multi-Phase Optical Disc Drive Mechanism for Compact Computers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In compact all-in-one personal computers, the large display unit obstructs access to the optical disc drive, making it inconvenient for users to insert or remove compact discs.
Innovation Solution
A multi-phase mechanism is introduced, where the storage device is slidably disposed in the host and the carriage is movable within the storage device, allowing for easy extraction of compact discs by first pulling the carriage to an end position and then sliding the storage device out, reducing the force required for disc removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display unit is made larger to improve viewing experience, then the display area is increased, but the optical disc drive becomes obstructed and difficult to access
Solution Approach 1:
The optical disc drive mechanism is segmented into two independent movable parts: the storage device (ODD) and the carriage. The carriage can move independently along the storage device, allowing the ODD to remain partially retracted while still providing disc access. This segmentation enables the display unit to be larger without completely obstructing the optical disc drive, as the carriage can extend to allow disc insertion/removal even when the main ODD body is retracted behind the display unit.
2Ease of operation
If the optical disc drive is made more accessible by extending it, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The carriage is nested within the storage device (ODD), with the carriage sliding along the length of the ODD housing. When the carriage extends, it allows the disc to be accessed; when retracted, the ODD remains compact. This nesting arrangement provides accessibility without requiring the entire ODD to be permanently extended, thus avoiding excessive complexity while still enabling easy disc operations.
3Ease of operation
If a multi-phase mechanism is introduced to improve accessibility, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The optical disc drive mechanism transitions from a static single-position design to a dynamic multi-phase system with two independently controllable movements: carriage extension and storage device retraction. This dynamic system allows the ODD to adapt its position based on operational needs, providing ease of disc removal while the complexity is managed through standardized sliding mechanisms that can be integrated into existing AIO PC designs without requiring entirely new mechanical systems.

AI summary
An electronic device with multi-phase mechanism including a host, a storage device and a carriage is provided in the present invention. The storage device is slidably disposed in the host and adapted to be pulled out from the host. The carriage is slidably disposed in the storage device and adapted to be pulled out from the storage device. Through the storage device slidably disposing in the host and being adapted to be pulled out from the host, it facilitates the user to take or replace a content from the storage device. When the carriage is moved out from the storage device in a first phase and then the storage device is pulled out from the host in a second phase, the content in the storage device is taken out.
