Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern ventilation systems in electric aircraft are inefficient in reducing battery temperatures, which can lead to overheating during flight or charging operations.
Innovation Solution
A venting assembly is designed for electric aircraft, comprising multiple battery packs with attached vents and an outlet located on a side different from the egress, allowing for effective temperature regulation by directing battery ejecta away from the aircraft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If modern ventilation systems are used to cool batteries, then battery temperature reduction is attempted, but the systems are inefficient and cannot adequately prevent overheating
Solution Approach 1:
The patent extracts the harmful hot air directly from the battery compartment through dedicated vents positioned adjacent to the batteries, separating the heat removal function from the general ventilation system. This extraction approach allows targeted thermal management at the heat source rather than relying on inefficient general circulation.
Solution Approach 2:
The patent introduces an intermediary venting assembly that includes vents, conduits, and outlets positioned specifically to intercept and channel hot air away from batteries. This intermediary structure mediates between the heat-generating batteries and the external environment, providing an efficient thermal management pathway.
2Device complexity
If vents are positioned on the same side as egress, then structural simplicity is maintained, but safety is compromised due to potential exposure of heated air to occupants
Solution Approach 1:
The patent employs asymmetric positioning where the venting assembly is configured with outlets on sides of the aircraft different from the egress location. This asymmetric arrangement ensures that hot air is discharged away from passenger exits, creating spatial separation between the harmful thermal plume and occupied zones while maintaining structural integration.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement by positioning vents adjacent to batteries and routing outlets to different sides of the aircraft fuselage. This dimensional approach distributes thermal discharge across multiple locations rather than concentrating it, effectively removing heated air from the immediate battery environment and directing it away from egress areas.
