Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing fuzzy extraction technology is used, then binary data can be processed, but real number data cannot be processed

Engineering Contradiction:
Improvedata type compatibilityVSAvoiderror correction capability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent changes the fundamental parameter of data representation from binary to real number domain. By formulating error correction codes in the real number field rather than binary field, the system achieves versatility across different data types while maintaining error correction reliability through mathematical transformations that preserve error detection and correction capabilities in the continuous domain.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention creates a universal error correction framework that can handle both binary and real number data. By developing a generalized error correction code that operates in the real number domain, the system achieves multi-functionality where the same theoretical framework applies to different data types, eliminating the limitation of binary-only processing while maintaining robust error correction.

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

2Reliability

If data conversion to binary is performed, then existing error correction can be applied, but processing accuracy decreases

Engineering Contradiction:
Improveerror correction applicabilityVSAvoiddata processing accuracy
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

Instead of converting real number data to binary for error correction, the patent inverts the approach by developing error correction codes that natively operate in the real number domain. This eliminates the accuracy loss from conversion while maintaining error correction capability, as the correction algorithms work directly with continuous values rather than discretized binary representations.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent replaces the mechanical binary conversion process with a mathematical substitution approach. By using real number field arithmetic and continuous error correction algorithms instead of binary field operations, the system maintains measurement precision while achieving error correction through mathematical transformations that preserve the continuous nature of the data.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If binary conversion is performed, then error correction is possible, but processing time increases

Engineering Contradiction:
Improveerror correction capabilityVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary formulation of error correction codes in the real number domain, eliminating the need for subsequent binary conversion steps. By pre-establishing the error correction framework to work natively with real number data, the system removes unnecessary conversion overhead and achieves faster processing while maintaining error correction capability throughout the data pipeline.

Inventive Principle:
Principle #10Preliminary action
