Hard Disk Drive Fixing Device for Stable Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing devices for hard disk drives are complicated to attach and detach, require multiple components, increasing costs, and may cause unstable fixing due to vibration-induced rattling.
Innovation Solution
A hard disk drive fixing device with a case main body, rotatable retaining portions, and a joint portion with a lock claw, allowing easy attachment and detachment, stable fixing, and reduced component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking body separate from the base portion is used with multiple engagement portions, then the fixing device can securely hold the protected body, but the number of components increases and member cost increases
Solution Approach 1:
The locking body and base portion are integrated into a single unified structure. The locking body includes a pressing portion that presses the protected body against the base portion, eliminating the need for separate components while maintaining the securing function through the integrated design
2Reliability
If multiple engagement portions are used for attaching and detaching the protected body, then the fixing can be more secure, but the attachment and detachment process becomes complicated
Solution Approach 1:
The fixing device uses a simplified single engagement portion design where the locking body can be easily attached and detached from the base portion. This segmentation allows for straightforward operation while maintaining secure fixing through the pressing mechanism that holds the protected body against the base portion
3Device complexity
If one pressing portion presses the central portion of the upper surface of the protected body, then the structure is simple, but the upper surface may separate from the buffer body causing rattling due to vibration
Solution Approach 1:
The locking body incorporates an asymmetric pressing portion design that presses the protected body at an optimal position against the base portion. This asymmetric positioning prevents separation and rattling caused by vibration while maintaining structural simplicity, avoiding the need for complex multi-point pressing mechanisms

AI summary
This fixing device comprises: a case body having an accommodation space for accommodating an object to be fixed on the inside of circumferential wall parts standing from a bottom wall part; a pair of retaining parts rotatably connected to the case body and bridge over an upper opening of a circumferential wall part on the opposite side of the bottom wall part; and a connecting part connecting the distal rotational ends of the pair of retaining parts. The circumferential wall parts include a front wall part and a rear wall part opposing each other across the accommodation space. The pair of retaining parts have curved surfaces protruding into the accommodation space, and the proximal rotational end sides thereof are connected to the rear wall part by a hinge part. The connecting part has a lock claw that engages with the front wall part from the inside of the accommodation space.
