Solution Overview

Problem

Existing methods for transferring files between devices are cumbersome, insecure, and require network connectivity, which can expose data to breaches and incur data charges, while traditional storage devices are easily lost and inconvenient.

Innovation Solution

A modular portable storage system with a housing containing a processor, storage module, wireless communication module, and power supply, enabling direct device-to-device communication through a standardized communication system (SCS) using chips like 802.11 or Bluetooth, allowing secure file transfer without networks and supporting various platforms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If network communication is used for file transfer, then data transfer capability is improved, but security risk increases due to network breaches

Engineering Contradiction:

Improvedata transfer capabilityVSAvoidsecurity risk

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a portable storage device as an intermediary between source and destination devices. Data is transferred through this intermediate storage medium rather than directly over the network, eliminating exposure to network breaches while maintaining transfer capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Weight of moving object

If traditional USB storage devices are used, then portability is improved, but ease of operation deteriorates due to risk of loss and misplacement

Engineering Contradiction:

ImproveportabilityVSAvoidconvenience

Core Design Contradiction:

Weight of moving objectVSEase of operation

Solution Approach 1:

The patent merges the portable storage device with a power bank into a single integrated unit. This combination eliminates the need to carry separate devices, reducing the number of items to track while maintaining portability and adding charging functionality.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If modular design is implemented, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improveplatform compatibilityVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements universal communication interfaces that support multiple protocols (Bluetooth, NFC, USB) within a single device. This allows one portable storage device to work with various platforms (smartphones, tablets, computers) without requiring different hardware variants, simplifying the overall system while maintaining broad adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A modular portable storage system includes a portable storage device with a housing having a cuboid geometry. The housing retains a processor, a storage module in electronic communication with the processor, and a wireless communication module. A circuit may communicate electronically with the portable storage device. The portable storage device may be removably coupled to the circuit board. A power supply may be in electronic communication with the circuit board. The power supply may also be removably coupled to the circuit board. The portable storage device and the power supply may be removably retained within the external housing. The circuit board may be mechanically coupled to the external housing. A case for a mobile device may define a cavity to retain the portable storage device.
