Solution Overview

Problem

Existing hot-swappable storage devices face challenges with signal cable management and entanglement, leading to signal quality issues due to the need for longer signal paths during hot swapping, which disrupts data transfer operations.

Innovation Solution

Incorporating a wireless communication interface in the hot-swappable storage device and host end to enable continuous data transfer by switching to wireless communication when the physical connection is disconnected, using technologies like LiFi, WiFi, or Bluetooth to maintain data transfer quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a signal cable with certain length is connected between host end and storage device, then data transfer operation can be maintained during hot swapping, but the chassis needs to have certain length and signal quality is affected due to longer path

Engineering Contradiction:

Improvedata transfer continuityVSAvoidchassis length

Core Design Contradiction:

ReliabilityVSLength of stationary object

Solution Approach 1:

The patent replaces the mechanical cable connection system with a wireless communication system. The wireless communication interface eliminates the need for physical signal cables, allowing data transfer to continue when the storage device is pulled out for maintenance, while avoiding the chassis length constraint and signal quality degradation caused by long cable paths.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If a signal cable with certain length is connected between host end and storage device, then data transfer operation can be maintained during hot swapping, but the signal cable is not easy to manage and assemble and entanglement readily occurs

Engineering Contradiction:

Improvedata transfer continuityVSAvoidcable management

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent eliminates the mechanical cable management problem by replacing the physical signal cable with a wireless communication interface. This substitution removes the entanglement and management issues associated with cables while maintaining the ability to transfer data during hot swapping operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If a signal cable with certain length is connected between host end and storage device, then data transfer operation can be maintained during hot swapping, but signal quality is affected due to longer path
