Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional burners are used to create practice fires, then open flames of different fire classes can be generated for training, but realistic heat development and smoke generation of electrical accumulator fires cannot be simulated
Solution Approach 1:
The patent changes the operational parameters of the burner device by introducing a heating burner that can operate in two modes: conventional open flame mode and heating mode. In heating mode, the burner generates heat without visible flames, allowing the simulation of smoldering electrical accumulator fires. This parameter change enables the device to realistically replicate the thermal characteristics of battery fires while maintaining training safety.
Solution Approach 2:
The patent creates a simplified model of electrical accumulator fire behavior using heat-radiating surfaces that replicate the thermal characteristics of actual battery fires. The heating burner generates controlled heat patterns that copy the smoldering fire behavior of lithium-ion batteries, providing realistic training scenarios without the dangers of real battery fires.
2Adaptability or versatility
If real battery fires are used for training, then realistic fire scenarios can be practiced, but safety cannot be guaranteed and training can only be performed once
Solution Approach 1:
The patent uses disposable or replaceable heat-radiating surfaces that can be safely discarded after use. These surfaces simulate battery fire conditions but do not pose the same safety risks as real batteries. The system allows unlimited training repetitions by replacing the simulated fire components rather than dealing with actual hazardous materials.
Solution Approach 2:
The heating burner device acts as an intermediary between the trainer and the training scenario. It generates controlled thermal conditions that simulate battery fires without the inherent dangers of real battery chemistry. The heat-radiating surfaces serve as intermediaries that transfer thermal energy for training purposes while maintaining safety through controlled, contained heating.
3Adaptability or versatility
If heating burner device generates multiple individually controllable flames, then different heat levels and hot spots can be created for thermal imaging training, but device complexity increases
Solution Approach 1:
The heating burner device is segmented into multiple independently controllable heating zones or flames. Each zone can be controlled separately to create different heat levels and hot spots on the heat-radiating surfaces. This segmentation allows the simulation of varied fire scenarios including localized hot spots and distributed heating patterns, while each zone can be independently adjusted for training requirements.

AI summary
To improve training opportunities for various fire scenarios, a fire training device 1 is proposed, which can realistically simulate a flameless, thermal decomposition process within an electric battery to enable corresponding fire extinguishing exercises. For this purpose, the fire training device 1 comprises several cuboid metal parts that can be heated internally by at least one heating flame from a heating burner device 4, causing the metal parts to heat up and radiate heat, similar to the outer casing of a battery that heats up considerably due to a short circuit or thermal decomposition process, although the heating flames are not visible from the outside.Furthermore, the fire protection training device 1 can be easily adapted/extended to simulate a fully developed accumulator fire, especially with the development of flash flames and/or smoke, and an accumulator explosion for training purposes (Figure 1).
