Screw-Free Fixing Structure for Detachable Electronic Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional screw-based fixing structures for detachable hard disk drives require numerous screws, increasing assembly time, production costs, and resource waste, while also necessitating professional tools for maintenance and replacement, which can lead to inefficiencies and lost components.
Innovation Solution
A screw-free fixing structure utilizing a housing with guiding bars and movable members, where the first movable member pivots to align a protrusion on the second movable member with a hole, allowing for secure attachment or release without screws, reducing assembly time and material costs, and simplifying user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw-based fixing structures are used, then the detachable electronic assembly can be securely fixed, but the assembly time increases and production costs rise
Solution Approach 1:
The patent removes screws entirely from the fixing mechanism, extracting the problematic fastening elements that caused assembly delays and cost increases. The screw-free design uses a snap-fit mechanism where the movable member directly engages with the housing through elastic deformation, eliminating the need for separate fastening components and simplifying the assembly process to a single insertion motion.
Solution Approach 2:
The movable member incorporates elastic elements that automatically provide the necessary fastening force when the member is inserted into the housing. The elastic deformation of the movable member creates a self-locking mechanism that secures the electronic assembly without requiring external tools or additional fastening operations, enabling quick assembly and disassembly by users.
2Reliability
If multiple screws are used for assembly, then the electronic assembly can be firmly fixed, but the material costs and resource waste increase
Solution Approach 1:
The patent merges the functions of multiple screws into a single integrated movable member. The movable member combines the structural support function, the fastening function, and the locking function into one component that elastically deforms to secure the electronic assembly. This consolidation reduces material consumption and eliminates the need for multiple separate fastening elements.
Solution Approach 2:
The snap-fit mechanism allows for easy disassembly and reassembly of the electronic assembly without damaging the movable member or housing. The elastic elements recover their original shape after each assembly cycle, enabling repeated use of the same components and reducing waste from discarded fastening elements.
3Reliability
If screw-based fixing is used, then the electronic assembly can be secured, but professional tools are required for maintenance which increases operational complexity
Solution Approach 1:
The movable member is designed to be manually operable without requiring specialized tools. Users can easily insert or remove the movable member by hand to access the electronic assembly for maintenance, upgrades, or replacements. The elastic fastening mechanism provides sufficient holding force during normal operation but allows simple manual removal when needed.
Solution Approach 2:
Instead of requiring tools to tighten or loosen fastening elements, the patent inverts the approach by using a push-to-release mechanism where applying force in the insertion direction locks the assembly, while removing that force allows easy release. This reversal of the traditional fastening logic simplifies user interaction and eliminates the need for screwdrivers or other professional tools.

AI summary
A fixing structure is for a detachable electronic assembly. The detachable electronic assembly has at least one first hole. The fixing structure includes a housing, a first movable member, and a second movable member. In this case, the housing has at least one guiding bar, at least one fist connecting portion, and a first opening opposite to the first hole. The first movable member has a second opening and a second connecting portion. The first movable member is pivoted on the housing, and the second connecting portion connects with the first connecting portion. The second movable member has a third opening and a protrusion. The second movable member moves along the guiding bar caused by the rotation of the first movable member, so that the protrusion is inserted into the first opening and the first hole. An apparatus having a fixing structure is also provided.
