Solution Overview

Problem

Existing communication methods between devices often require network connections, which may not be available and can expose data to security breaches, and devices with different wireless chips are unable to communicate effectively, limiting file transfer and storage solutions, especially for consumer devices like cameras that use SD cards with limited storage.

Innovation Solution

A system comprising a host device with an SD emulator card that includes a processor and wireless chip, allowing communication via SD protocol with the host device and standardized communication protocol with a portable storage device, enabling direct peer-to-peer data transfer without networks and across different device platforms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If network communication is used for data transfer between devices, then communication range is extended, but security risks increase and network availability is required

Engineering Contradiction:

Improvesecurity risksVSAvoidcommunication availability

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent introduces an SD emulator card as an intermediary device between the host device and portable storage device. This mediator enables direct peer-to-peer communication through standardized protocols while maintaining SD card compatibility, thereby eliminating network dependency and associated security risks without compromising communication availability

Inventive Principle:

Principle #24Intermediary (Mediator)

2Speed

If specialized wireless chips are used for direct communication, then communication speed improves, but device compatibility decreases

Engineering Contradiction:

Improvecommunication speedVSAvoiddevice compatibility

Core Design Contradiction:

SpeedVSAdaptability or versatility

Solution Approach 1:

The SD emulator card is designed with multi-functionality to serve multiple purposes: it acts as an SD card interface for the host device, contains a wireless chip for direct communication, and implements protocol conversion capabilities. This universal design enables both high-speed direct communication and broad device compatibility across different platforms

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Quantity of substance

If SD card storage is used in consumer devices, then data storage capacity is provided, but storage space is limited and data access is time-consuming

Engineering Contradiction:

Improvestorage capacityVSAvoiddata access time

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The patent replaces the mechanical SD card storage system with a wireless digital communication system. The SD emulator card substitutes physical data transfer through SD protocols with electronic wireless transmission, eliminating the need to physically remove and insert SD cards while providing access to significantly larger storage capacities on the portable storage device

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
