Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection between a storage device and a hard disk in a chassis is often unstable when the storage device is inserted, leading to potential disconnection issues.
Innovation Solution
A locking device comprising a housing, linking members, a push-pull member, a stopper, and a resilient member, which works by sliding and rotating mechanisms to securely fix the storage device to the chassis, ensuring stable connection and easy insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple insertion mechanism is used, then ease of operation is improved, but connection stability deteriorates
Solution Approach 1:
The locking device employs dynamic elements including a movable stopper that slides along the pushing direction and rotatable linking members that pivot to engage with the storage device. This dynamic mechanism allows the system to transition from an unlocked to a locked state, providing stable connection while maintaining ease of operation through simple push-pull motion of the push-pull member.
Solution Approach 2:
The resilient member automatically returns the stopper to its initial position after being pushed, enabling the locking device to self-reset without external intervention. This self-service mechanism ensures the storage device remains securely locked while allowing easy removal when needed, resolving the contradiction between connection stability and ease of operation.
2Reliability
If a locking mechanism is added to improve connection stability, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a single compact locking device structure. The housing contains the stopper, linking members, and resilient member in a unified assembly that attaches to the chassis. This merging of components achieves reliable connection stability while minimizing the increase in overall device complexity through efficient spatial arrangement and functional integration.
Solution Approach 2:
The linking members are rotatably connected within the housing structure, with the stopper nested within the housing and the resilient member positioned to bias the stopper. This nested arrangement allows the locking mechanism to achieve reliable connection stability while maintaining a compact form factor and avoiding excessive structural complexity.
3Ease of operation
If a push-pull mechanism with linking members is used, then ease of operation is improved, but manufacturing complexity increases
Solution Approach 1:
The locking device is divided into distinct functional segments: the housing, the stopper, the linking members, and the resilient member. Each component can be manufactured separately using standard machining and molding processes, then assembled together. This segmentation improves ease of removal through the push-pull mechanism while managing manufacturing complexity by breaking down the overall structure into simpler, independently manufacturable parts.

AI summary
A locking device includes a housing, a first linking member, a second linking member, a push-pull member, and a stopper. The push-pull member defines a first sliding groove. A first end portion of the first linking member is slidably received in the first sliding groove, and a second end portion of the first linking member is rotationally fixed on the housing. The housing defines a second sliding groove. The stopper is slidably received in the second sliding groove. A second end portion of the second linking member is rotationally mounted on the first linking member. The first end portion of the first linking member is driven by the push-pull member to move along the first sliding groove, which drives the second linking member to rotate, which drives the stopper to move along the second sliding groove.
