Optical Disc Loading Mechanism With Interlocking Levers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing slot-in type optical disc drives have a complex disc loading structure that is not stable, difficult to assemble, and requires multiple elements, making it economically inefficient and prone to errors during disc loading and unloading.
Innovation Solution
A simplified disc loading apparatus with a frame base, spindle motor, disc guide walls, rotational disc centering lever, and ejecting lever, featuring interlocking levers and a gear apparatus to facilitate easy disc loading and unloading, optimized for a standard disc size to reduce manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a complex disc loading structure with multiple levers is used, then the disc loading function is achieved, but the structure becomes difficult to assemble and less stable
Solution Approach 1:
The patent combines multiple separate levers into an integrated disc loading structure. The loading lever and ejecting lever are merged with the guide wall assembly, reducing the number of discrete components that need to be assembled while maintaining the full loading and ejecting functionality.
Solution Approach 2:
The guide wall assembly serves multiple functions: it guides the disc during loading, provides structural support for the loading mechanism, and integrates the ejecting lever mechanism. This multi-functionality reduces the overall number of components needed in the system.
2Ease of manufacture
If multiple separate elements are used for disc loading and unloading, then the loading function is achieved, but manufacturing costs increase
Solution Approach 1:
Multiple functional elements are merged into integrated assemblies. The loading lever, ejecting lever, and guide walls form a unified structure that reduces the total number of parts manufactured and assembled, thereby lowering manufacturing costs.
Solution Approach 2:
The integrated loading structure performs multiple functions (guiding, loading, ejecting) within a single assembly, reducing the quantity of separate elements that need to be manufactured and inventory-managed.
3Reliability
If a complex structure with multiple levers is used, then disc loading capability is provided, but operational stability decreases
Solution Approach 1:
The loading and ejecting mechanisms are merged into a stable integrated structure that reduces the number of moving parts and connection points, thereby improving operational reliability and reducing potential failure points.
Solution Approach 2:
Instead of using multiple separate levers that connect through multiple joints, the patent inverts the approach by using a integrated structure with fewer connection points, which inherently provides greater stability and fewer opportunities for operational failure.

AI summary
A disc loading apparatus is provided. The disc loading apparatus includes a frame base, a spindle motor installed in the frame base, a disc guide wall disposed at one side of the frame base and configured to guide a loading of a disc, a disc loading structure disposed in front of another side of the frame base and disposed parallel to a direction in which the disc enters to load the disc on the spindle motor, a rotational disc centering lever disposed adjacent to the guide wall to center the disc with respect to the spindle motor, and an ejecting lever disposed at a rear side of the frame base and configured to unload the disc loaded on the spindle motor.
