Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional flowmeters (ball flow liter or flowmeter with integrated pressure reducer) are used, then the device complexity is low, but the measurement precision is poor (accuracy of ±10% to ±30%)

Engineering Contradiction:
Improveflow rate measurement accuracyVSAvoidsocket system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines the flowmeter with integrated pressure reducer and telecommunication module into a single unified socket assembly. This merging eliminates the need for separate external flowmeter devices while providing precise flow rate measurement (±2% accuracy) and remote monitoring capabilities, directly resolving the contradiction between measurement precision and device complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The socket is designed to perform multiple functions simultaneously: gas flow control, precise flow rate measurement, pressure reduction, and wireless telecommunication. This multi-functionality integrates what were previously separate components into one universal device, improving measurement precision without proportionally increasing complexity

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

2Loss of information

If conventional flowmeters without telecommunication means are used, then the ease of operation is high, but the loss of information is significant (cannot remotely monitor flow rates)

Engineering Contradiction:
Improveflow rate data transmissionVSAvoidoperational simplicity
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The socket incorporates telecommunication means that automatically transmit flow rate data to remote monitoring systems. This feedback mechanism eliminates information loss by continuously reporting actual flow rates, while the automated nature of the transmission maintains ease of operation without requiring additional manual steps

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The socket performs self-monitoring and self-reporting of flow rate data through integrated telecommunication means. This self-service capability eliminates the need for manual reading and recording by operators, preventing information loss while maintaining operational simplicity

Inventive Principle:
Principle #25Self-service

3Reliability

If frequent maintenance operations are performed, then the reliability is improved, but the productivity is reduced (downtime for maintenance)

Engineering Contradiction:
Improveflow monitoring reliabilityVSAvoidgas distribution continuity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The socket includes remotely replaceable batteries that can be monitored and replaced without physical access to the socket interior. This preliminary action capability allows maintenance to be performed only when necessary (based on battery status monitoring), maintaining reliability while minimizing interruptions to gas distribution productivity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces mechanical flow measurement systems with a fluidic oscillation flowmeter that has no moving parts requiring maintenance. This substitution eliminates mechanical wear and tear, ensuring long-term reliability while maintaining continuous operation and productivity

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

4Measurement precision

If high power consumption components are used, then the measurement precision and telecommunication capability are improved, but the use of energy increases (reducing battery life)

Engineering Contradiction:
Improveflow rate measurement accuracyVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The telecommunication module is designed to transmit data periodically rather than continuously, and the flowmeter uses oscillation-based measurement that consumes minimal energy. This periodic action approach maintains measurement precision and communication capability while significantly reducing overall energy consumption to extend battery life

Inventive Principle:
Principle #19Periodic action
