Wing Battery Support Bracket With Foam Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
All-electric aircraft using batteries as a power source face challenges when mounting batteries on the wing, as it increases vibration load and may make the wing too heavy, complicating aircraft control. Mounting batteries on the fuselage reduces passenger and luggage space, while mounting on the wing requires additional reinforcement to manage vibration and weight.
Innovation Solution
A battery support body with a bracket and shock absorber system is used to secure batteries on the wing, incorporating foam elements to absorb vibrations and maintain structural integrity, thereby reducing weight and enhancing rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If batteries are mounted on the wing, then space for passengers and luggage is preserved, but the wing becomes too heavy and vibration load increases
Solution Approach 1:
The battery mounting system is divided into modular brackets that can be independently attached to the wing structure. This segmentation allows for optimized weight distribution and enables the use of lighter materials in non-critical areas while maintaining structural integrity where needed.
Solution Approach 2:
The patent employs composite materials for the battery brackets and mounting structures, combining materials with high strength-to-weight ratios. This allows the wing to support battery weight while minimizing the overall weight increase, resolving the contradiction between preserving passenger space and avoiding excessive wing weight.
2Area of stationary object
If batteries are mounted on the wing, then space for passengers and luggage is preserved, but vibration load on the aircraft increases
Solution Approach 1:
The patent incorporates vibration-damping elements and shock-absorbing features in the battery mounting brackets before the aircraft encounters turbulent conditions. These pre-installed cushioning elements reduce the transmission of vibration loads from the batteries to the wing structure, allowing batteries to be mounted on the wing without excessively increasing vibration load.
Solution Approach 2:
The mounting brackets act as intermediary elements between the batteries and the wing structure. These brackets are designed with vibration-isolating features that mediate the connection, reducing the harmful vibration loads transmitted to the aircraft while maintaining secure battery attachment.
3Strength
If additional reinforcement is added to the wing for batteries, then structural integrity is improved, but the wing becomes too heavy
Solution Approach 1:
Instead of uniformly reinforcing the entire wing structure, the patent applies reinforcement only in the local areas where batteries are mounted. The brackets and mounting structures provide targeted structural strengthening at specific locations, maintaining structural integrity while minimizing overall weight increase.
Solution Approach 2:
The reinforcement strategy is segmented into discrete mounting brackets and localized structural enhancements rather than comprehensive wing reinforcement. This allows structural integrity to be improved at battery mounting locations without adding excessive weight to the entire wing structure.
