Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicle (UAV) controllers are vulnerable to environmental conditions, such as breaking from drops and overheating, and their control elements and antennas are susceptible to damage and interference, affecting communication and accuracy.
Innovation Solution
A clamshell cover integrates antennas and control elements, providing protection and improved RF communication by angling antennas towards the UAV, with a conductive plane to direct RF energy and insulating plane to isolate it from the user, along with a heatsink and fan for cooling and a support mechanism for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control elements and antennas are exposed for operation, then ease of operation and communication are improved, but vulnerability to damage from drops and environmental conditions increases
Solution Approach 1:
The cover is designed to be movable between open and closed positions, allowing the controller to dynamically adapt its protection level based on operational needs. When open, control elements are accessible for operation; when closed, they are protected from damage.
Solution Approach 2:
The controller is divided into separate functional sections: a movable cover containing control elements and antennas, and a base containing inertial measurement units and other sensitive circuitry. This segmentation allows each part to be optimized independently for its specific function.
2Reliability
If antennas are positioned for optimal RF communication, then communication range is improved, but susceptibility to interference and damage increases
Solution Approach 1:
The antennas are integrated into the movable cover, allowing their position to be dynamically adjusted. When the cover is opened for operation, antennas are positioned for optimal communication; when closed, they are protected within the cover structure.
Solution Approach 2:
A conductive plane is introduced as an intermediary between the antennas and the environment. This conductive plane directs RF energy toward the UAV while blocking external interference, serving as a protective mediator that maintains communication effectiveness while reducing susceptibility to harmful factors.
3Reliability
If control elements are made robust for durability, then protection from damage is improved, but accuracy of inertial measurement units may be affected by mechanical stress
Solution Approach 1:
The controller is segmented into a cover section containing robust control elements and a base section containing sensitive IMUs. This physical separation prevents mechanical stress from durable control elements from affecting IMU accuracy.
Solution Approach 2:
The movable cover acts as an intermediary structure that isolates the IMUs from direct mechanical stress. The cover can be opened and closed without transmitting significant force to the IMUs in the base, protecting measurement precision while allowing durable control elements.
