Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned electronic devices, such as drones, face challenges in maintaining a stable hovering state due to external factors like wind and propeller operation, leading to tilting and inaccurate flight control signals, which result in unnecessary movements and energy consumption.
Innovation Solution
An electronic device equipped with a gimbal, multiple cameras, and sensors that use processors to detect changes in angle and maintain camera horizontality, compensating for tilts and adjusting flight controls to stabilize hovering without unnecessary movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the OFS module is mounted on the bottom surface to detect ground points for hovering control, then the hovering function is enabled, but the module tilts with the airframe causing inaccurate position identification and unnecessary flight corrections
Solution Approach 1:
The patent separates the OFS module from the airframe by mounting it on an independently controllable support structure (such as a gimbal or extended arm). This segmentation allows the OFS module to maintain a fixed orientation relative to the ground while the airframe tilts, resolving the contradiction between enabling hovering control and maintaining detection accuracy.
Solution Approach 2:
The patent introduces an intermediary mechanism (such as a gimbal system or adjustable mounting structure) between the airframe and the OFS module. This intermediary compensates for airframe tilting by actively adjusting the OFS module's orientation to remain horizontal, thereby maintaining accurate ground point detection while preserving hovering functionality.
2Extent of automation
If flight control signals are generated to return to original position based on tilted OFS module data, then the control system responds to detected movements, but unnecessary operations are performed when the device is actually stationary
Solution Approach 1:
The patent implements a feedback mechanism where the orientation of the OFS module is continuously monitored and used to validate position changes. By ensuring the OFS module remains horizontal through active compensation, the system receives accurate feedback about actual ground position changes, enabling the automatic flight control to distinguish between real drift and apparent movement caused by tilting, thus avoiding unnecessary energy-consuming corrections.
3Adaptability or versatility
If the airframe tilts due to external factors during hovering, then the device adapts to external forces, but the mounted OFS module tilts causing measurement errors
Solution Approach 1:
The patent employs a counterbalancing mechanism where the support structure for the OFS module actively compensates for tilting forces. When external factors cause the airframe to tilt, the support structure generates opposing adjustments to maintain the OFS module in a horizontal position, effectively neutralizing the harmful effect of airframe tilting on measurement accuracy while preserving the ability to adapt to external conditions.
