Compact Push-Push Hard Disk Mounting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hard disk installations with push-push apparatuses face space inefficiencies due to the large size of heart-shaped cams, which occupy significant space and hinder compact design configurations.
Innovation Solution
A push-push apparatus design incorporating an elastic rod and sliding slots that utilize elastic members and a locking mechanism to efficiently insert and remove hard disks, allowing for compact positioning and retrieval by sliding along multiple slots with varying lengths and depths, enabling precise movement and locking for secure installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If heart-shaped cams are used in the push-push apparatus, then the hard disk can be installed and removed, but the apparatus occupies a large space
Solution Approach 1:
The patent extracts the heart-shaped cam mechanism from the push-push apparatus and replaces it with a linear guide structure consisting of a guide groove and guide column. This extraction of the bulky cam mechanism eliminates the need for large curved paths while maintaining the push-push functionality, thereby reducing the overall space occupation of the apparatus.
Solution Approach 2:
Instead of using a cam mechanism that converts linear motion to rotational motion and back, the patent inverts the approach by using a direct linear guide structure where the pressing member moves linearly along the guide groove. This inversion of the motion conversion mechanism eliminates the need for curved cam paths and reduces space requirements.
2Area of stationary object
If a compact design is implemented, then space usage is optimized, but the reliability of hard disk installation may be compromised
Solution Approach 1:
The patent introduces a locking member as an intermediary component that works with the locking groove to secure the pressing member in the inserted position. This locking mechanism ensures that the hard disk remains securely installed while allowing the apparatus to maintain a compact design, thus preserving reliability despite reduced space occupation.
Solution Approach 2:
The guide groove is divided into multiple segments including a first sliding groove, a second sliding groove, and a locking groove. This segmentation allows the pressing member to follow a controlled path with distinct phases: insertion, locking, and ejection. The segmented structure ensures reliable operation while maintaining compact dimensions by optimizing the path of each segment.

AI summary
A small-volume push-push apparatus for mounting and demounting a hard disk includes a pressing member, a bracket, and an elastic rod. The bracket defines first to fourth sliding slots, and the elastic rod includes a sliding portion. The pressing member can drive the sliding portion to slide along the first to fourth sliding slots in sequence. When the sliding portion slides to an ending point of the first sliding slot and intersects with the second sliding slot, the bracket can move at a first direction. When the sliding portion slides to a starting point of the first sliding slot away from the fourth sliding slot, the bracket can move in a second direction opposite to the first direction.
