Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing miniaturized USB memory apparatuses face challenges in incorporating a LED indicator without increasing volume, as the space between the metallic conductive housing and the print circuit board assembly is insufficient, and the use of flake spacers complicates manufacturing and miniaturization.
Innovation Solution
A USB memory apparatus with a housing featuring orientated indentations and concave props that securely fix the print circuit board assembly, allowing for a space to accommodate additional components like a LED indicator without increasing the overall volume, using a metallic conductive material and punched concave props for improved manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a flake spacer is used to fill the space between the metallic conductive housing and the PCBA, then the PCBA is fitted tightly in the housing, but the manufacturing process becomes complicated and miniaturization is hindered
Solution Approach 1:
The patent removes the flake spacer component entirely from the assembly. Instead of adding a spacer to fill the space between the housing and PCBA, the design accepts the natural gap created by the thin PCBA, thereby eliminating the manufacturing complexity associated with fabricating and installing spacers while maintaining the compact form factor
Solution Approach 2:
The housing is designed with integrated positioning features and structural elements that segment the internal space to accommodate the PCBA and LED indicator without requiring additional spacer components. The housing structure itself is segmented to provide both mechanical support and space allocation for different functional elements
2Adaptability or versatility
If a LED indicator is introduced into the USB memory apparatus, then the device provides additional functionality, but the volume increases due to lack of space
Solution Approach 1:
The patent utilizes the vertical dimension and existing internal cavities of the housing structure to accommodate the LED indicator. By positioning the LED indicator in the space between the housing and PCBA (which exists naturally without spacers) and utilizing the thickness dimension of the housing, the design adds functionality without increasing the overall footprint or volume of the apparatus
Solution Approach 2:
The housing structure is designed to serve multiple functions simultaneously: it provides mechanical protection, defines the external dimensions, creates internal positioning for the PCBA, and accommodates the LED indicator. This multi-functionality allows the addition of the LED indicator without requiring separate dedicated space that would increase overall volume
3Reliability
If the thickness of the PCBA is increased to accommodate data reading and storing, then the functionality is improved, but the overall height and miniaturization are compromised
Solution Approach 1:
The patent uses a PCBA with minimal necessary thickness to achieve the required data reading and storing functionality. Rather than increasing thickness beyond what is needed for reliable operation, the design accepts the thin PCBA configuration and compensates through optimized housing structure and component placement, thereby maintaining miniaturization while ensuring adequate functional reliability
