Multi-Rotor UAV Sensor Layout for EMI-Resistant Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) face reliability issues due to interference from electrical components affecting onboard sensors, and user mis-configuration or assembly errors can lead to malfunctions or damage.
Innovation Solution
The UAV design separates interference-generating electrical components from sensors by locating them inside a cavity, with sensors positioned outside or on extension members, and pre-configures electrical components to reduce user assembly errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electrical components are placed inside the UAV housing for compact integration, then device complexity is reduced and ease of manufacture is improved, but sensor operation reliability deteriorates due to electromagnetic interference
Solution Approach 1:
The patent divides the UAV into distinct functional zones: an internal housing containing electrical components and an external platform containing sensors. This spatial segmentation isolates electromagnetic interference sources from sensitive sensors while maintaining integrated operation, resolving the contradiction between compact integration and sensor reliability
Solution Approach 2:
The patent introduces an extension member as an intermediary structure that physically connects the internal housing to the external platform. This intermediary allows electrical components and sensors to be mounted on separate platforms while maintaining structural integration, thereby reducing interference while preserving device compactness
2Volume of moving object
If sensors are positioned close to electrical components for compact design, then device volume is reduced, but measurement precision deteriorates due to interference from electrical components
Solution Approach 1:
The patent transitions from a single-plane layout to a three-dimensional configuration by mounting sensors on an external platform extended from the main housing. This dimensional change allows sensors to be positioned at a distance from electrical components without significantly increasing the overall UAV volume, thereby preserving measurement precision while maintaining compact design
3Adaptability or versatility
If users perform assembly and configuration of sensors and electrical components, then adaptability is improved, but reliability deteriorates due to user mis-configuration or assembly errors
Solution Approach 1:
The patent implements pre-configured electrical components with predetermined connections and settings established during manufacturing. This preliminary action ensures proper configuration before user deployment, eliminating assembly errors and mis-configuration while maintaining adaptability through selectable component combinations
