Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a noncontact communication device uses only one communication standard, then the device structure remains simple, but the compatibility with noncontact storage media of various standards is limited

Engineering Contradiction:
Improvecompatibility with noncontact storage mediaVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The noncontact communication device is designed to support multiple communication standards (ISO 14443-4 Type A, Type B, and FeliCA) within a single device architecture. The processor can dynamically switch between different communication protocols, enabling the device to communicate with noncontact storage media of various standards without requiring separate dedicated devices for each standard.

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

2Adaptability or versatility

If the processor tries to support multiple communication standards simultaneously, then compatibility improves, but the processing complexity and time increase

Engineering Contradiction:
Improvecommunication standard compatibilityVSAvoidcommunication establishment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary detection of the noncontact storage medium's communication standard before actual data communication begins. The processor sends detection commands to identify which communication standard (Type A, Type B, or FeliCA) the storage medium uses, and then configures the communication parameters accordingly. This preliminary action prevents trial-and-error communication attempts and reduces overall communication establishment time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The communication device employs dynamic protocol switching capability, where the processor can adaptively change communication parameters based on the detected storage medium type. The system dynamically adjusts communication standards, data formats, and protocol settings during operation, allowing seamless transition between different communication standards without requiring physical hardware changes.

Inventive Principle:
Principle #15Dynamics
