Solution Overview

Problem

The installation of hard disks in server devices is time-consuming and inconvenient due to the need for screw fastening, which complicates the process and increases costs.

Innovation Solution

A holding device with a frame module and an accommodation unit, featuring a tray and elastic plates that can securely fasten hard disks without tools, using a connecting rod structure to move the tray and push the elastic plates for tool-less fixation and release.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hard disks are fastened on the supporting rack with screws, then the hard disks are securely fixed and vibration is prevented, but the installation process becomes time-consuming and complicated

Engineering Contradiction:
Improvesecure fixation of hard diskVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The elastic plates are designed to automatically clamp the hard disk when the tray is inserted into the frame module. The protrusions on the lateral plates automatically push the elastic plates toward the accommodation space, creating a self-fastening mechanism that eliminates the need for manual screw tightening

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The traditional screw-fastening mechanical system is replaced with an elastic deformation-based fastening system. The elastic plates utilize elastic deformation to provide clamping force, substituting the complex screw-thread mechanical engagement with a simpler elastic contact mechanism

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If hard disks are fastened with screws before assembly, then the hard disks are securely mounted, but the operation becomes inconvenient and complex

Engineering Contradiction:
Improvesecure mounting of hard diskVSAvoidconvenience of installation and removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The fastening system performs both fastening and release operations automatically through the elastic deformation of the plates. When the tray is inserted, the plates automatically clamp; when removed, they automatically release, making the system self-operating and highly convenient

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The elastic plates transition from a static fastening state to a dynamic response based on tray insertion. The system adapts its fastening force automatically based on the presence or absence of the tray, providing optimal operation convenience

Inventive Principle:
Principle #15Dynamics

3Reliability

If a large number of screws are used for fastening, then the hard disks are securely fixed, but the process is complicated and operation is inconvenient

Engineering Contradiction:
Improvesecure fastening of hard diskVSAvoidcomplexity of fastening process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fastening function is segmented from the tray structure and implemented through separate elastic plates. This segmentation allows the fastening mechanism to operate independently through elastic deformation, eliminating the need for multiple screws and simplifying the overall device structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The screws are completely extracted from the fastening mechanism. The patent removes the screw fastening elements entirely and replaces them with an elastic plate-based system that achieves secure fastening without any threaded fasteners

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A holding device includes a frame module and an accommodation unit. The frame module includes a plate body and two lateral plates oppositely disposed on the first plate body. A placement area is collectively defined by the plate body and the lateral plates. Two protrusions are respectively provided on the lateral plates. The accommodation unit includes a tray and two elastic plates. The tray is slidably located within the placement area, and an accommodation space is defined between two opposite sides of the tray. Each elastic plate is elastically connected to one of opposite sides of the tray. When the tray is moved after a load is placed within the accommodation space, the protrusions respectively push the elastic plates towards the accommodation space so that the load is toollessly fastened between the elastic plates.
