Flash Drive Elastic Arm Carrier Positioning Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flash drives face issues with stable positioning and structural strength due to poor design, leading to the connector being pushed back inside the housing during connection, compromising portability and usability.
Innovation Solution
Incorporating an elastic arm on the carrier that protrudes away from the storage module, allowing it to generate an elastic force that enhances the interference between the carrier and housing, preventing bending deformation and ensuring stable engagement with the housing's engaging slots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector is movably assembled inside the housing to enable connection with peripheral devices, then the portability and usability are improved, but the structural stability deteriorates causing the connector to be pushed back inside the housing during connection
Solution Approach 1:
The elastic arm is designed to be deformable along the second axis, allowing it to dynamically adjust its shape during connector movement. When the carrier moves along the first axis to extend the connector, the elastic arm deforms accordingly; when the connector is pushed back, the elastic arm absorbs the impact through deformation and then returns to its original shape, providing dynamic stability rather than rigid fixation
Solution Approach 2:
The elastic arm changes its physical state by deforming along the second axis in response to forces applied during connector movement. This parameter change (shape deformation) allows the arm to absorb external forces and maintain the carrier's positioning stability while still permitting the intended movement of the connector in and out of the housing
2Stability of the object's composition
If the elastic arm protrudes away from the storage module to increase interference force with the housing, then the positioning stability is improved, but the structural strength against bending deformation deteriorates
Solution Approach 1:
The elastic arm is designed to deform along the second axis, which is perpendicular to the first axis of carrier movement. This dimensional separation allows the arm to provide positioning stability through its protrusion and deformation in one dimension (second axis) while its structural design (contour, thickness, material properties) maintains resistance to bending deformation in the direction of carrier movement (first axis)
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 elastic arm increases the structural strength and stability of the carrier, preventing the connector from being pushed back into the housing during connection, thus improving the flash drive's portability and usability by maintaining a stable positioning effect.
Implementation Method 1
The elastic arm is deformable along a second axis... the elastic force generated by the elastic arm increases the interference force between the carrier and the housing

AI summary
A flash drive including a housing, a carrier, and a storage module is provided. The carrier is movably disposed inside the housing along a first axis. The carrier has an elastic arm being deformable along a second axis. The storage module is assembled to the carrier to move together with the carrier in relative to the housing, so that a connector of the storage module is moved outside the housing or hidden inside the housing. The elastic arm has a contour protruded along a direction away from the storage module when not receiving force.
