Solution Overview
Problem
Conventional motor mounting systems for small engines, such as those in UAVs, are cumbersome to install and remove, requiring numerous fasteners and customized vibration isolation, which can lead to performance issues due to varying operational conditions.
Innovation Solution
A modular motor housing with quick-connect and quick-disconnect mounting brackets and integrated vibration isolation, allowing for easy motor replacement and tuning, eliminating the need for separate vibration isolation hardware and tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mounting arrangements use multiple fasteners and separate vibration isolation components, then the motor can be securely mounted, but the installation and removal process becomes cumbersome and time-consuming
Solution Approach 1:
The patent combines the motor mounting structure and vibration isolation components into a single integrated modular housing unit. The housing includes integrated vibration isolation elements (elastomeric materials, compliant mounts) built into the structure itself, eliminating the need for separate vibration isolation components and multiple fasteners. This allows the entire motor assembly to be installed or removed as one unit by simply detaching the housing from the aircraft structure.
Solution Approach 2:
The motor mounting system is divided into modular components: a removable housing that contains the motor and integrated vibration isolation, and a fixed mounting structure attached to the aircraft. This segmentation allows the housing to be easily detached and reattached without affecting the aircraft structure, enabling rapid motor replacement while maintaining secure mounting during operation.
2Reliability
If conventional mounting systems require customized vibration isolation for each motor and aircraft combination, then vibration isolation can be optimized, but the system complexity and customization requirements increase
Solution Approach 1:
The modular housing design with integrated vibration isolation components creates a universal mounting system that can accommodate different motor types and aircraft configurations. The housing includes standardized mounting interfaces and adaptable vibration isolation elements (such as elastomeric materials and compliant mounts) that provide effective vibration isolation across various applications without requiring custom-designed isolation components for each motor-aircraft combination.
3Strength
If motors are rigidly attached to the aircraft structure, then mechanical damage from vibration is prevented, but the motor performance may deviate due to strong vibrations
Solution Approach 1:
The patent introduces vibration isolation components as an intermediary between the motor housing and the aircraft structure. These components (elastomeric materials, compliant mounts) absorb and dampen vibrations, protecting the motor from mechanical damage while isolating it from excessive vibrations that could cause operational deviations. The intermediary layer allows controlled vibration isolation while maintaining secure mechanical attachment.
