Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fire-fighting pipeline is provided to discharge fire-fighting medium when pressure relief mechanism is actuated, then the temperature control and safety response is improved, but condensation may form on the pipeline affecting electrical components
Solution Approach 1:
An isolation layer is introduced as an intermediary between the fire-fighting pipeline and the surrounding environment. This isolation layer prevents direct contact between condensation-prone surfaces and electrical components, thereby eliminating the harmful effect of condensation while preserving the temperature control function of the pipeline.
Solution Approach 2:
The harmful effect of condensation is extracted and isolated from the electrical components by wrapping the fire-fighting pipeline with an isolation layer. This separates the condensation-prone pipeline surface from sensitive electrical parts, allowing the pipeline to function without compromising component safety.
2Stress or pressure
If pressure relief mechanism is actuated to relieve internal pressure, then pressure control is improved, but the fire-fighting pipeline may be damaged by emissions
Solution Approach 1:
The isolation layer serves as a protective cushion that absorbs and dissipates the impact of emissions discharged from the pressure relief mechanism. This pre-positioned protective layer prevents direct damage to the fire-fighting pipeline while allowing pressure relief to occur effectively.
3Temperature
If fire-fighting medium is discharged to lower battery cell temperature, then temperature control is improved, but condensate formation may cause short circuits
Solution Approach 1:
The isolation layer acts as an intermediary barrier that prevents condensate formed on the fire-fighting pipeline from contacting electrical components. This maintains the electrical performance and reliability of the system while allowing continuous temperature control through fire-fighting medium discharge.
4Object-affected harmful factors
If isolation layer is added to cover fire-fighting pipeline, then condensation protection is improved, but device complexity increases
Solution Approach 1:
A flexible isolation layer in the form of a thin film or wrap is used to cover the fire-fighting pipeline. This simple, adaptable covering provides effective condensation protection without significantly increasing device complexity, as it can be easily applied and does not require complex structural modifications.
