Tray-less Disc Drive Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tray-type disc drives have complex internal structures and require additional space for tray ejection, which can lead to tray wobbling and motor damage during rapid ejection, and occupy more space due to the need for tray reservation.
Innovation Solution
A tray-less disc drive design featuring a driving unit, moving member, traverse, and disc positioning structure, where the moving member and traverse work together to clamp and release discs without a tray, using a multi-linkage structure and restoring mechanism to support and unload discs without contact, allowing for compact internal design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tray is used to carry the disc, then the disc can be easily loaded and unloaded, but the internal structure becomes complicated and more space is required
Solution Approach 1:
The patent extracts and removes the tray from the disc drive system, eliminating the complex tray mechanism while maintaining disc loading and unloading functionality through alternative means (direct disc insertion and ejection mechanisms without a tray structure)
2Speed
If the tray is ejected quickly, then the operation speed is improved, but the tray may wobble or the motor may be damaged
Solution Approach 1:
By removing the tray entirely from the system, the patent eliminates the problems of tray wobble and motor damage during rapid ejection, as there is no tray to wobble or require careful controlled ejection
3Ease of operation
If space is reserved for the ejected tray, then the tray can be completely ejected, but the disc drive occupies more space
Solution Approach 1:
The patent removes the tray component entirely, eliminating the need to reserve space for tray ejection, thereby reducing the overall disc drive volume while maintaining complete disc removal capability

AI summary
A disc drive has an opening portion for inserting a disc. The disc drive includes a driving unit, a moving member, a traverse, a disc positioning structure and a restoring structure. When the disc is intended to be clamped on the traverse, the driving unit drives the moving member to move the traverse to a disc holding position to clamp the disc; and the moving member moves the disc positioning structure to a disc release position so that the disc positioning structure does not contact the disc. When the disc is intended to be released from the traverse, the driving unit drives the moving member to move the traverse to a disc unloading position to unload the disc; and the restoring structure moves the disc positioning structure to a disc loading position to support the disc.
