Lateral Battery Compartment for Electric Aircraft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The placement of batteries in electric aircraft can affect aircraft weight, balance, and maintenance accessibility, as existing configurations often position batteries beneath the passenger compartment, making them difficult to access, recharge, inspect, or replace.
Innovation Solution
The battery compartment is located laterally adjacent to the passenger seats along the longitudinal axis of the fuselage, with movable access panels allowing external access for convenient recharging, inspection, and replacement, while maintaining the usable volume of the passenger cabin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If batteries are positioned beneath the passenger compartment, then the aircraft can achieve better weight distribution, but maintenance accessibility and battery access become difficult
Solution Approach 1:
The battery compartment is extracted from the conventional location beneath the passenger compartment and repositioned to a lateral position adjacent to the seats. This extraction allows the battery to be accessed through the fuselage exterior while maintaining its weight distribution benefits, thereby resolving the contradiction between stable weight composition and ease of repair.
2Ease of repair
If batteries are positioned for easy external access, then maintenance becomes convenient, but aircraft balance and weight distribution may be affected
Solution Approach 1:
The battery compartment is positioned at a specific lateral location within the fuselage that is optimized for both external accessibility and weight distribution. This localized positioning ensures that the battery can be accessed through the fuselage exterior while maintaining proper aircraft balance, resolving the contradiction between ease of repair and stability of composition.
3Ease of repair
If battery compartment is located laterally adjacent to seats, then maintenance accessibility improves, but aircraft interior space may be reduced
Solution Approach 1:
Instead of positioning the battery compartment in the conventional horizontal plane beneath the passenger compartment, the invention utilizes the lateral dimension adjacent to the seats. This dimensional change allows the battery to be accessed through the fuselage exterior while minimizing impact on passenger cabin space, resolving the contradiction between ease of maintenance and volume of the aircraft interior.
