Memory Disk Elastic Connector Dust Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing memory disks with large capacity flash memory face issues with dust protection and ease of use, as the small cover can be easily lost, compromising the USB connector's dust prevention function when not in use.
Innovation Solution
A memory disk design featuring a hollow casing with an elastic member and base, where the connector is secured within the casing using an engagement portion and protrusion mechanism, allowing easy assembly and disassembly for use and storage, and including a strap for convenient carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a small cover is used to protect the USB connector, then the dust prevention function is achieved, but the cover is easily lost
Solution Approach 1:
The patent merges the cover function with the hollow casing structure. The hollow casing itself serves as both the protective housing and the cover that protects the USB connector when not in use. This integration eliminates the separate small cover that was prone to loss, while maintaining dust prevention functionality through the enclosed structure of the hollow casing.
Solution Approach 2:
The USB connector is nested within the hollow casing structure. When the connector is not in use, it is stored inside the hollow casing, which acts as its protective cover. This nesting arrangement ensures the connector is always protected without requiring a separate cover component.
2Ease of operation
If the connector is always exposed, then ease of use is improved, but dust can enter the connector
Solution Approach 1:
The design allows the hollow casing to dynamically transition between open and closed states. The elastic member enables the casing to be easily opened for connector access and automatically closed when not in use, providing adaptive protection that responds to usage conditions.
Solution Approach 2:
The elastic member provides automatic resetting functionality. After the hollow casing is opened for connector use, the elastic member automatically returns the casing to its closed protective position when released, ensuring dust prevention without requiring user intervention.
3Reliability
If a secure attachment mechanism is used, then the storage device is firmly held, but assembly and disassembly become complex
Solution Approach 1:
The attachment mechanism is segmented into simple modular components: the elastic member and the engagement portion with protrusion-recess interface. This segmentation allows each component to perform its function simply while collectively providing secure attachment, avoiding complex integrated mechanisms.
Solution Approach 2:
The patent extracts the fastening function into a separate elastic member component that can be easily assembled and disassembled. This extracted mechanism provides secure attachment through the engagement portion and protrusion-recess interface without complicating the overall device structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents dust from entering the USB connector and minimizes the risk of the cover being lost, ensuring the connector's functionality while allowing easy handling and storage.
Implementation Method 1
the elastic member is deformed to make the engagement portion wedge in the recess and against the protrusion
Implementation Method 2
the elastic member is similarly fastened at the recess to prevent the storage device from departing from the hollow casing

AI summary
A memory disk structure includes a storage device, a hollow casing, an elastic member and a base. The storage device has a connector and a main body. The connector is installed in one end of the main body. The hollow casing has an opening and a recess with a protrusion. The elastic member and the base are attached to the main body, and the base has an engagement portion. When the connector passes through the opening of the hollow casing to make connector pushed into the hollow casing, the elastic member is deformed to make the engagement portion wedge in the recess and against the protrusion, and when the body is pushed into the hollow casing and the connector is exposed outside the hollow casing, the elastic member is fastened at the first recess to prevent the storage device from departing from the hollow casing.
