Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional fire simulation evaluation scenarios (oil pot fire, wood stack fire) are used for testing fireproof materials, then the testing process is simple and equipment requirements are low, but the evaluation effect is weak and does not match actual cable channel scenarios
Solution Approach 1:
The testing system is divided into multiple independent modules including open flame system, air circulation system, water circulation system, and control system. Each module performs a specific function (flame generation, air flow control, cooling/suppression, automated control), allowing the complex simulation scenario to be built from manageable components while achieving realistic cable channel fire evaluation
Solution Approach 2:
The testing platform integrates multiple functions into a single system: it can simulate different cable channel environments, control air flow patterns, generate standardized open flames, and automate the entire testing process. This multi-functional design enables accurate replication of real-world cable fire scenarios while maintaining systematic organization
2Reliability
If fire protection materials testing is conducted with flame combustion and product pyrolysis processes, then realistic fire conditions are simulated, but heat build-up and violent smoke generation occur causing difficulty for conventional laboratory hardware
Solution Approach 1:
The water circulation system is pre-configured with cooling channels and spray mechanisms positioned to activate during testing. This advance preparation of cooling infrastructure allows the system to handle heat build-up and smoke generation from realistic fire simulations without overwhelming conventional laboratory equipment
Solution Approach 2:
The air circulation system acts as an intermediary between the flame source and the surrounding environment, controlling air flow to manage combustion intensity and smoke dispersion. The water circulation system serves as a thermal intermediary, absorbing and removing excess heat through controlled cooling, thereby protecting laboratory hardware while maintaining accurate fire condition simulation
