Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a data transmission circuit is used to store and transmit data, then data storage capability is improved, but node floating due to leakage currents reduces reliability

Engineering Contradiction:
Improvedata integrityVSAvoidnode floating
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The reset control circuit generates reset signals in advance based on input data patterns that may cause node floating. When specific data patterns are detected, the circuit proactively activates reset signals to prevent node floating before it occurs, rather than reacting after the problem manifests.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The circuit monitors input data patterns and uses this information to control the generation of reset signals. The reset control circuit receives feedback from the data input circuit about potential floating conditions and adjusts reset signal generation accordingly, creating a closed-loop control system that prevents node floating.

Inventive Principle:
Principle #23Feedback

2Reliability

If a reset control circuit is added to prevent node floating, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidcircuit structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The reset control circuit is integrated with the existing data transmission circuit components, including the enable controller and current mirror component. By merging the reset control functionality into the existing circuit architecture rather than adding completely separate components, the patent reduces overall device complexity while still achieving reliable prevention of node floating.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The reset control circuit serves multiple functions: it generates reset signals based on input data patterns, prevents node floating, and maintains data integrity. This multi-functional approach allows a single circuit addition to address multiple potential issues simultaneously, reducing the need for additional separate components and thereby limiting the increase in device complexity.

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