Optical Disc Drive Ejecting Mechanism for Safe Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical disc drives risk damaging discs when users improperly remove them from the drive, leading to data loss due to improper force application.
Innovation Solution
An optical disc drive with an ejecting mechanism featuring a button, reposition assembly, and ejecting assembly that applies a controlled upward force to release the disc from the chuck claw, preventing damage during ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user directly removes the optical disc from the turntable by hand, then the disc can be removed quickly, but the disc may be damaged by improper force applied by the user
Solution Approach 1:
The patent introduces an ejecting mechanism as an intermediary between the user and the optical disc. When the user presses the button, the ejecting assembly (including the push rod and elastic component) automatically pushes the disc away from the chuck claw, eliminating the need for the user to directly apply force to the disc and thus preventing damage.
Solution Approach 2:
The ejecting mechanism utilizes the elastic component (spring) to store and release energy automatically. When the button is pressed, the elastic component is compressed and then automatically pushes the push rod to eject the disc when released, making the system self-serving without requiring continuous user input or direct manual manipulation of the disc.
2Reliability
If the chuck claw holds the optical disc firmly, then the disc is securely fixed on the turntable, but the user cannot easily remove the disc
Solution Approach 1:
The patent implements a dynamic ejection system where the ejecting assembly can transition between different states. The push rod can move between a retracted position (when not in use) and an extended position (when ejecting the disc). The elastic component dynamically adjusts to store and release energy, enabling the system to switch between holding and ejecting modes as needed.
Solution Approach 2:
The ejecting mechanism performs preliminary action by pre-positioning the push rod and elastic component ready for ejection. When the button is pressed, the elastic component is pre-compressed and immediately releases to push the disc away from the chuck claw, enabling quick and effortless disc removal without requiring the user to apply force.
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
Enables safe and effortless disc removal by using a spring-assisted mechanism to push the disc away from the chuck claw, reducing the risk of data loss and damage.
Implementation Method 1
the reposition assembly is adjacent to the button and provides the button with a return force along a first direction
Implementation Method 2
the ejecting assembly has a first portion pivotally connected to the connecting portion, a second portion pivotally connected to the turntable and a third portion protruding out the turntable
Data Source
AI summary
An optical disc drive is suitable to read data of an optical disc. The optical disc drive includes a housing, a turntable and an ejecting mechanism. The turntable has a chuck claw holds at an opening of the optical disc. The ejecting mechanism includes a button, a reposition assembly and at least an ejecting assembly. The button is configured at the turntable and has an operating portion and a connecting portion. The reposition assembly is adjacent to the button and provides the button with a return force along a first direction. Moreover, the ejecting assembly has a first portion connected to the connecting portion, a second portion connected to the turntable and a third portion protruding out the turntable. When the operating portion is forced and moves along a second direction, the connecting portion drives the third portion to move along the first direction and push the optical disc.
