Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional electric vehicle combustion experimental platforms are used, then fire characteristics can be studied, but the platforms are surrounded by wire mesh which is not suitable for garage scenes and lack specific measuring points design
Solution Approach 1:
The measurement system is divided into multiple independent temperature acquisition units positioned at different locations (roof, headstock, bottom, inner-temperature). Each unit can be independently adjusted and positioned, allowing the system to adapt to garage environments without requiring a complex enclosed platform structure.
Solution Approach 2:
The temperature acquisition units employ length-adjustable structures and rotating adjustable mechanisms that allow dynamic repositioning of measurement points. This enables the system to adapt to different vehicle types and garage configurations without fixed platform constraints.
2Measurement precision
If comprehensive fire parameters are measured, then fire mechanism analysis is improved, but the device complexity and measurement system requirements increase
Solution Approach 1:
The system integrates multiple measurement functions (temperature, radiation, gas composition, heat release rate) into a unified measurement platform. The computer system coordinates all sensors and data acquisition units, providing comprehensive fire parameter measurement without requiring separate complex systems for each parameter.
Solution Approach 2:
The computer acts as an intermediary that coordinates data acquisition from multiple sensors including thermocouples, radiation sensors, and gas analyzers. It processes and integrates data from all measurement units, simplifying the complexity of managing multiple measurement systems simultaneously.
3Measurement precision
If multiple temperature acquisition units are positioned at different locations, then temperature distribution measurement is improved, but the installation complexity and adjustment requirements increase
Solution Approach 1:
The temperature acquisition units incorporate length-adjustable structures and rotating adjustable mechanisms that allow easy repositioning of measurement points. The rotating adjustable structure at the bottom acquisition unit enables convenient angular adjustment without complex installation procedures.
Solution Approach 2:
The system is designed with pre-configured measurement positions and adjustable structures that facilitate straightforward installation. The acquisition units can be positioned at required locations before the fire test begins, with adjustments made during setup rather than requiring complex in-situ modifications.
