Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If flash memory cards are frequently inserted and removed from card readers, then data transfer between host devices is enabled, but mechanical wear occurs and operation becomes cumbersome

Engineering Contradiction:

Improvedata transfer capabilityVSAvoidmanual insertion and removal

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical card insertion/removal system with a wireless communication system. The flash memory card includes a wireless interface that enables data transfer without physical connection to card readers, eliminating the need for frequent manual insertion and removal operations while maintaining data transfer capability between host devices.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If dedicated card reader slots are used for each flash memory device type, then reliable data transfer is achieved, but compatibility across different host devices is limited

Engineering Contradiction:

Improvedata transfer reliabilityVSAvoidcross-device compatibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements a universal wireless interface on the flash memory card that can communicate with multiple types of host devices without requiring device-specific card readers. The wireless communication protocol enables the same flash memory card to transfer data reliably across different host devices such as computers, cameras, and mobile phones, achieving both reliability and cross-device compatibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If conventional wired interfaces are used for data transfer, then stable connection is maintained, but portability and ease of use are reduced

Engineering Contradiction:

Improveconnection stabilityVSAvoiddevice portability

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The patent replaces the physical wired connection with wireless communication technology. The flash memory card incorporates a wireless interface that transmits data through electromagnetic waves, eliminating the need for physical cables and connectors. This maintains connection stability through protocol-level error correction and retransmission mechanisms while dramatically improving portability by removing all physical connection requirements.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
