Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If concentration measurements and separate laboratory fire tests are used to prove equivalency, then current testing methods are satisfactory for their intended purpose, but they do not effectively demonstrate the correlation between agent concentration and fire suppression performance

Engineering Contradiction:
Improvecorrelation measurement between concentration and performanceVSAvoidtesting method complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines concentration measurement and fire suppression performance testing into a single integrated test chamber. The test chamber simultaneously measures agent concentration through sensors and evaluates fire suppression performance through flame characteristic measurements, eliminating the need for separate laboratory fire tests and demonstrating the correlation between concentration and performance in one unified system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces an intermediary test chamber that serves as a mediator between concentration measurement and fire suppression performance evaluation. This intermediate testing environment allows direct observation of how agent concentration affects flame characteristics, providing a causal link between the two previously separate measurement processes.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If traditional concentration testing methods are used, then testing can be conducted in controlled environments, but they fail to directly demonstrate fire suppression performance correlation

Engineering Contradiction:
Improvefire suppression performance validationVSAvoidtesting system complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The test chamber is designed with multi-functionality, serving both as a concentration measurement device and a fire suppression performance evaluation system. It incorporates sensors for measuring agent concentration, flame characteristics, and other fire parameters, allowing a single system to perform multiple testing functions that were previously required separate systems.

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

3Measurement precision

If separate laboratory fire tests are conducted, then fire suppression performance can be evaluated, but the correlation with agent concentration cannot be directly demonstrated

Engineering Contradiction:
Improveperformance-concentration correlationVSAvoidtesting time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The test chamber is pre-configured with sensors and measurement systems before testing begins. Concentration sensors and flame characteristic measurement devices are positioned and calibrated in advance, allowing immediate measurement of the correlation between agent concentration and fire suppression performance as the test progresses, eliminating the need for post-test analysis and separate laboratory evaluations.

Inventive Principle:
