Fuselage Battery Support Structure for Crash Load Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Urban air mobility vehicles face safety concerns due to significant collision loads applied to the occupant space during crashes, which existing structures fail to adequately disperse, compromising occupant safety.
Innovation Solution
A battery load support structure is implemented, featuring a battery mount support mounted on the fuselage's floor frame, with a joint unit connecting to multiple framework members, including a front, center, and rear bulkheads, to enhance load dispersion and structural reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a battery mount support is mounted on the floor frame with a simple structure, then the device complexity is reduced, but the load supporting performance deteriorates under collision loads
Solution Approach 1:
The battery mount support is divided into multiple segments including a support body, front joint, center joint, and rear joint. Each segment connects to different bulkheads (front bulkhead, center bulkhead, rear bulkhead) to distribute collision loads across multiple attachment points rather than concentrating them at a single location, thereby improving load supporting performance while maintaining reasonable structural complexity
Solution Approach 2:
The battery mount support extends in the longitudinal direction of the fuselage, utilizing the longitudinal dimension to span across multiple bulkheads. This dimensional extension allows the support structure to engage with multiple framework members along the length of the fuselage, distributing loads across a greater spatial extent and improving overall structural strength
2Ease of manufacture
If the battery unit is fastened to a single location on the floor frame, then the ease of manufacture is improved, but the stability deteriorates during collision
Solution Approach 1:
The fastening system is segmented into multiple attachment points located at the front joint, center joint, and rear joint of the battery mount support. Each joint connects to a separate bulkhead, creating multiple fastening locations that work together to stabilize the battery unit and occupant space during collision, rather than relying on a single fastening point
Solution Approach 2:
The battery mount support merges multiple functional elements including the support body, front joint, center joint, and rear joint into a single integrated structure. This merged structure provides multiple fastening locations simultaneously, achieving both manufacturing efficiency (as a single component) and enhanced stability (through multiple attachment points)
