Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical copying method is used to transfer data between hard disks, then data storage records are retained and data recovery is enabled, but simultaneous operation of two computers is required which is inconvenient for users

Engineering Contradiction:
Improvedata recovery capabilityVSAvoiduser convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a data transfer device as an intermediary between two computers. This device includes a shared disk that can be accessed by both computers simultaneously, eliminating the need for users to manually operate both computers at the same time while still enabling data transfer and recovery operations

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If existing data transfer devices are used, then data can be transferred between computers, but they lack versatility in interfacing different types of devices

Engineering Contradiction:
Improvedata transfer capabilityVSAvoiddevice interface compatibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements a universal interface mechanism in the data transfer device that can connect to different types of devices including computers, smartphones, and other electronic devices. The device serves multiple functions: data transfer, file sharing, and compatibility with various device types through standardized connection interfaces

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If physical copying method is used, then data can be transferred independently of computer operations, but copying speed cannot be adjusted according to user needs

Engineering Contradiction:
Improveindependent operation capabilityVSAvoidcopying speed flexibility
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent implements dynamic speed adjustment capability in the data transfer device. The copying speed can be adjusted according to user needs through software control, allowing the system to adapt between fast copying modes for productivity and slower modes for precision or compatibility requirements

Inventive Principle:
Principle #15Dynamics

4Device complexity

If single type of interface is used in data transfer device, then device structure is simplified, but cannot transfer data between different types of devices

Engineering Contradiction:
Improveinterface type varietyVSAvoidcross-device data transfer capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements a universal interface mechanism that consolidates multiple interface types into a single unified connection system. This universal interface can recognize and communicate with different device types (computers, smartphones, tablets) through protocol adaptation, maintaining simple device structure while enabling broad compatibility

Inventive Principle:
Principle #6Universality (Multi-functionality)
