Portable Storage Device Resilient Cover Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable storage devices with USB connectors often lose their dust-proof function when in use due to the cover being misplaced, and there is a risk of the small cover being lost, compromising the device's convenience and functionality.
Innovation Solution
A portable storage device design featuring a hollow housing with a resilient member that secures the memory device both when the connector is exposed and when it is inserted, using a hanging belt for convenience, ensuring dust-proofing and preventing loss by allowing the connector to be easily inserted or removed while maintaining protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is separated from the portable storage device during use, then the connector can be inserted into the computer, but the dust-proof function is lost and the cover may be lost
Solution Approach 1:
The cover is integrated into the hollow housing structure, forming a nested configuration where the cover is received by the housing. This ensures the cover remains attached to the device while allowing the connector to be exposed for insertion, maintaining both ease of operation and dust-proof function simultaneously.
Solution Approach 2:
The resilient member enables dynamic adjustment of the cover position. When the memory device is inserted, the resilient member allows the cover to move and expose the connector; when the memory device is removed, the resilient member returns the cover to its protective position, automatically maintaining dust-proof function based on usage state.
2Reliability
If the cover is kept on the portable storage device, then the USB connector is protected from dust, but the connector cannot be easily accessed for use
Solution Approach 1:
The resilient member creates a dynamic system where the cover automatically adjusts its position based on the insertion state of the memory device. During use, the cover moves to expose the connector for easy access; when not in use, the cover returns to protect the connector, resolving the contradiction between protection and accessibility.
Solution Approach 2:
The hollow housing is pre-configured with a receiving space for the cover and a resilient member that is already positioned to facilitate cover movement. This preliminary arrangement ensures that when the memory device is inserted, the cover is automatically positioned to expose the connector without requiring additional user actions.
3Volume of moving object
If the memory device is made small for portability, then the device volume is reduced, but the cover is easily lost
Solution Approach 1:
The cover is nested within the hollow housing structure, forming an integrated compact design. This nested configuration maintains the small device volume while ensuring the cover remains securely attached to the housing, preventing loss despite the reduced size.
Solution Approach 2:
The cover and hollow housing are merged into a single integrated structure rather than separate components. This merging ensures the cover cannot be lost separately while maintaining the compact portable size of the overall device.
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 solution provides a convenient and dust-proof portable storage device that prevents loss and ensures the connector remains protected during use, enhancing user experience and device reliability.
Implementation Method 1
the resilient member is wedged into the first concave portion. When the body has been pushed in to the hollow housing and the connector is exposed out of the hollow housing, the resilient member is also wedged into the first concave portion to avoid the memory device separate from the hollow housing
Implementation Method 2
When the body has been exerted a pressure through the second opening, the resilient member separates from the first concave portion

AI summary
A portable storage device structure is described. A memory device has a connector and a first concave portion. An opening defined on a hollow housing to form two sections of the hollow housing with different lengths. The longer section has a second concave portion. A resilient member has one end secured to the second concave portion to suspend the opposite end. When the memory device assembles to the hollow housing, the opposite end of the resilient member engages with the first concave portion to avoid the memory device from slipping out of the housing.
