Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a gas purification device is added to purify poisonous vapors before discharge, then the environmental protection is improved, but the device complexity increases
Solution Approach 1:
The patent changes the temperature parameter of the escaping gases by introducing a flow path that allows gases to cool down naturally as they travel from the accommodation space through the base body to the ventilation opening. This temperature reduction transforms the state of the gases, reducing their harmfulness without adding complex purification devices.
Solution Approach 2:
The patent extracts the harmful thermal energy from the gases by utilizing the base body as a heat sink. The base body absorbs excess heat from the gases during their flow path, effectively removing the thermal hazard component without requiring an active cooling system or complex purification apparatus.
2Temperature
If heat-insulating material is added to line the outer walls for heat insulation, then the heat protection is improved, but the device complexity increases
Solution Approach 1:
The base body serves multiple functions simultaneously: it provides structural support for the transportation device, acts as a heat sink to cool the escaping gases, and serves as a radiation surface for heat dissipation. This multi-functionality eliminates the need for separate heat-insulating layers, maintaining simplicity while achieving thermal protection.
Solution Approach 2:
The base body creates a thermal buffer zone between the hot gases and the external environment. By utilizing the thermal mass and radiation surface of the base body, it establishes a protective thermal environment that prevents direct heat transfer to the exterior without requiring additional insulating materials.
3Temperature
If the flow path length is increased to allow more cooling, then the gas cooling effect is improved, but the effective volume ratio decreases
Solution Approach 1:
The patent utilizes the three-dimensional space of the base body by routing the flow path along multiple external walls (at least three, preferably four) rather than a simple linear path. This spatial arrangement increases the cooling surface area and flow path length without proportionally increasing the device volume, thereby maintaining an effective volume ratio while achieving充分的 cooling.
Solution Approach 2:
The flow path is nested within the structural framework of the base body, utilizing the walls and internal space of the existing structure. The path runs between the external case and the inner tank, effectively using the available space without requiring additional volume, thus maintaining high effective volume ratio while providing extended cooling path.
