Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional automata processors use separate state elements and transition elements to identify data patterns, then pattern matching capability is achieved, but array size and system complexity increase excessively

Engineering Contradiction:

Improvepattern matching capabilityVSAvoidarray size and system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines separate state elements and transition elements into integrated state transition elements. Each state transition element simultaneously performs state storage and transition logic functions, eliminating the need for separate transition elements. This merging reduces the overall array size while maintaining the capability to identify data patterns, directly resolving the contradiction between adaptability and device complexity.

Inventive Principle:

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

By merging state and transition elements into unified state transition elements, the patent reduces the total number of processing units required. This consolidation decreases resource usage and eliminates redundant operations between separate elements, thereby improving processing efficiency and speed while maintaining pattern identification capability.

Inventive Principle:
