Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional security mechanisms are used in IoT data sharing systems, then system structure is simple and easy to implement, but security reliability is insufficient against network attacks

Engineering Contradiction:
Improvedata securityVSAvoiddetection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the security detection process into multiple independent modules: attack detection module, error rate detection module, repetition rate detection module, and miss rate detection module. Each module calculates specific fuzzy sets for different security aspects, allowing the complex security detection task to be divided into manageable components that can be processed independently and then integrated.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces trapezoidal fuzzy sets as an intermediary mechanism between raw security data and security assessment results. The fuzzy sets (NADi, kei, kRi, kLi) serve as mediators that transform discrete attack counts and error rates into continuous membership values, enabling nuanced security evaluation that bridges the gap between simple counting and complex security analysis.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If comprehensive security detection is performed on IoT data, then measurement precision of security status is improved, but loss of time for data processing increases

Engineering Contradiction:
Improvesecurity detection accuracyVSAvoiddata processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by pre-defining the trapezoidal fuzzy set structures and membership function relationships before actual security detection. The framework establishes predetermined calculation methods for converting attack counts, error rates, repetition rates, and miss rates into fuzzy membership values, so that during runtime, only data collection and formula substitution are needed, significantly reducing processing time while maintaining comprehensive detection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent transforms security measurement from discrete integer counts (number of attacks) to continuous fuzzy membership values (0-1 scale). This parameter change allows for more precise security assessment by capturing partial truths and uncertainties, while the mathematical transformations use efficient computational formulas that balance precision with processing speed.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If fuzzy set calculations are performed for multiple security metrics, then measurement precision of security assessment is improved, but device complexity for calculation increases

Engineering Contradiction:
Improvesecurity metric precisionVSAvoidcalculation system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the fuzzy calculation workload into four separate detection modules, each responsible for one type of fuzzy set calculation (attack detection, error rate, repetition rate, miss rate). This segmentation allows each module to be optimized independently and reduces the complexity burden on any single component, while the overall system achieves comprehensive precision through the combination of all modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs a universal trapezoidal fuzzy set framework that can handle multiple different security metrics (attack counts, error rates, repetition rates, miss rates) using the same mathematical structure and membership function approach. This universal methodology reduces calculation system complexity by reusing the same fuzzy logic infrastructure across different detection tasks, rather than developing separate complex systems for each metric.

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