Integrated Memory Card With Switchable Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile phone designs require separate slots for microSD memory cards and nanoSIM cards, leading to inefficient architecture and increased space usage, as both types of cards need to be physically present for communication and storage functions.
Innovation Solution
A memory card with a communications unit and a storage unit integrated on the same card body, featuring multiple connection pins that can be switched between communication and storage functions using a processor and control switch, allowing for dual functionality without the need for additional cards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile phone uses separate card slots for microSD memory card and nanoSIM card, then both communication and storage functions can be supported, but the device occupies more space and increases architectural complexity
Solution Approach 1:
The patent combines the microSD memory card and nanoSIM card into a single integrated card structure. The card body contains both a memory chip for storage and a SIM card chip for communication, allowing both functions to be performed by inserting one card rather than two separate cards. This merging eliminates the need for separate card slots and reduces the overall space occupied in the mobile phone.
Solution Approach 2:
The integrated card is designed to perform multiple functions simultaneously - it serves as both a storage medium (microSD card function) and a communication credential (nanoSIM card function). The card includes multiple connection pins that can be selectively connected to different circuits based on the required function, making it a universal component that replaces two specialized cards.
2Adaptability or versatility
If a mobile phone design includes a card slot large enough to support microSD card, then storage function is achieved, but the card slot size increases compared to nanoSIM card slot
Solution Approach 1:
The integrated card merges the functions of microSD and nanoSIM cards into a single physical object with dimensions compatible with the larger microSD slot. By combining both card functions into one unit, the card can be inserted into a single slot that accommodates the larger form factor, eliminating the need for separate slots of different sizes.
3Adaptability or versatility
If two separate cards (microSD and nanoSIM) are used in a mobile phone, then communication and storage requirements are met, but device architecture becomes more complex
Solution Approach 1:
The patent merges two separate card insertion mechanisms into a single card slot design. The integrated card eliminates the need for separate mechanical structures, guides, and detection circuits for two different card types, thereby simplifying the overall device architecture while maintaining both communication and storage functionalities.
Solution Approach 2:
The single card slot is designed to universally accept the integrated card that provides multiple functions. The slot and its associated control circuits are configured to handle both SIM card communication protocols and memory card storage operations through a single interface, reducing architectural complexity.

AI summary
This application provides a memory card and a mobile terminal. The memory card includes a card body (1), a communications unit (2) and a storage unit (3) that are disposed on the card body (1). A plurality of connection pins are disposed on the card body (1), and the plurality of connection pins include a first connection pin, a second connection pin, and a third connection pin. The first connection pin is separately connected to the communications unit (2) and the storage unit (3), the second connection pin is separately connected to the communications unit (2) and the storage unit (3), and the third connection pin is connected to the communications unit (2). The memory card further includes a first processor (5) and a control switch (4). The first processor (5) is configured to control, by using the control switch (4), the first connection pin and the second connection pin to be connected to the communications unit (2) or the storage unit (3). During use, only connections from the communications unit (2) and the storage unit (3) of the memory card to a mobile unit need to be switched to meet a communication requirement and a storage requirement, and no extra two cards need to be placed. This facilitates an architecture design of the mobile terminal and improves applicability of the mobile terminal.
