Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional automatic disk feeding devices use complex mechanical structures to achieve automation, then automation capability is improved, but device complexity and occupied space increase
Solution Approach 1:
The patent combines multiple functions into a single integrated mechanism. The push member simultaneously performs disk pushing, clamping, and ejection functions through coordinated movement of its clamping arms and pushing portion, eliminating the need for separate mechanical pickup devices and reducing overall structural complexity while maintaining full automation capability
Solution Approach 2:
The push member is designed as a multi-functional component that can perform multiple operations: pushing disks during duplication, clamping disks for ejection, and releasing disks onto the ejection member. This universal component replaces multiple specialized devices, reducing device complexity while preserving automation
2Extent of automation
If conventional disk feeding devices use large mechanical structures to achieve automation, then automation capability is improved, but occupied space increases
Solution Approach 1:
By merging pushing and clamping functions into the single push member structure, the device requires minimal space. The push member operates within a compact area above the disk tray, eliminating the need for large mechanical pickup devices that would occupy significant factory space
3Ease of operation
If conventional devices use complex pick-up mechanisms to take out disks step by step, then disk ejection capability is improved, but device complexity and operation space increase
Solution Approach 1:
The push member integrates both pushing and clamping functions. The clamping arms extend to grip disks while the pushing portion contacts the disk tray, enabling simultaneous pushing and clamping in one structure. This eliminates complex separate pick-up mechanisms and reduces operational complexity
Solution Approach 2:
The push member dynamically adjusts its configuration during operation. The clamping arms can extend and retract, and the pushing portion moves vertically to contact or release the disk tray. This dynamic adaptability enables versatile disk handling operations with a simple, unified structure

AI summary
An automatic disk feeding device for a disk duplication device and method thereof which comprises two transport assemblies (2) disposed at both sides of a disc holder (1). Each transport assembly (2) comprises a linkage disk (20) which drives a connecting rod (30) to rotate, and then the connecting rod (30) moves a sliding block (50) which cooperates with a push member (60) and a slide rail (70) to slide to and fro. The sliding block (50) is defined with slant pushing grooves (52), and the slide rail (70) is defined with L-shaped tracks (71). The push member (60) is provided with pushing protrusions (61) and guiding protrusions (62) inserted in the pushing grooves (61) and the L-shaped tracks (71). Thereby, the push members (60) can clamp the disc by a horizontal extending method firstly, and then lift the disc, thus automatically taking out the disc in a small space.
