Memory Stick Convert Device Signal Format Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience due to the lack of a device that can convert signal formats between different memory sticks, such as Micro-SD, Trans Flash, and Memory Stick (Pro) Duo, requiring multiple memory sticks to be compatible with portable electronic products.
Innovation Solution
A memory stick convert device is designed with a lower and upper housing and a convert interface that includes a substrate, connecting chip, tab terminal, and elastic chip to convert signal formats between Micro-SD and Memory Stick (Pro) Duo, also compatible with Trans Flash, using a specific arrangement of connectors, slots, and elastic structures for secure insertion and electrical coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a convert device is designed to support multiple memory stick formats, then compatibility and versatility are improved, but device complexity increases
Solution Approach 1:
The convert device is designed with a universal interface structure that can accommodate multiple memory stick formats (Micro-SD, Trans Flash, Memory Stick Pro Duo) through a single device. The housing includes multiple cavities and positioning structures that adapt to different memory card shapes and sizes, allowing one device to perform multiple conversion functions without requiring separate converters for each format.
Solution Approach 2:
The patent introduces a conversion interface as an intermediary component between different memory stick formats. This interface includes signal conversion circuits and physical adaptation structures that mediate the connection between incompatible formats, enabling data transfer without requiring the host device to support each format natively.
2Adaptability or versatility
If the convert device includes multiple cavities and positioning structures for different memory formats, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The housing is segmented into multiple independent cavities, each designed for a specific memory card format. Each cavity includes its own positioning structures and elastic components. This segmentation allows for modular manufacturing where each cavity can be independently formed and tested, simplifying the overall manufacturing process despite the complexity of supporting multiple formats.
Solution Approach 2:
Different regions of the housing have specialized structures optimized for specific memory card types. For example, the first cavity has positioning structures for Micro-SD cards while the second cavity has different positioning for Memory Stick Pro Duo. This local quality approach allows each region to be manufactured with specific tolerances and features needed for that format, rather than requiring the entire housing to accommodate all formats uniformly.
3Reliability
If elastic components are added to ensure secure insertion and electrical coupling, then reliability is improved, but device complexity increases
Solution Approach 1:
Elastic components such as elastic pins and elastic contact pieces are incorporated into the housing and interface structures. These components automatically adjust to ensure reliable electrical contact when a memory card is inserted, without requiring external actuation or complex control mechanisms. The elastic elements self-regulate to maintain optimal contact pressure and alignment, ensuring reliable electrical coupling while adding minimal structural complexity.

AI summary
A memory stick convert device includes an upper housing and lower housing and a convert interface. An assembly of the upper housing and the lower housing has the same type of connector as the Memory Stick(Pro) Duo does at an end. The assembly includes a cavity to accommodate a Micro-SD stick. The convert interface is sandwiched between the upper housing and the lower housing to convert signal formats between the Memory Stick (Pro) Duo and the Micro-SD.
