Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable radar systems with multiple degrees of freedom cause negative effects on communication signals due to repeatability and accuracy issues, leading to false data and decreased system efficiency, and may experience contraction and locking problems if actuators do not synchronize during the folding process.
Innovation Solution
A foldable antenna system with only one degree of freedom, utilizing a single actuator that moves vertically and transforms into rotational movement for both antennas, ensuring synchronous movement and protection against environmental factors, allowing for compact and durable storage while maintaining signal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple degrees of freedom are used in the foldable mechanism, then the radar system can be folded into a compact position, but the repeatability and accuracy of antenna locations deteriorate
Solution Approach 1:
The foldable mechanism is divided into multiple segments (first antenna, second antenna, connecting elements) that can be independently positioned and controlled. Each segment has defined degrees of freedom that are controlled separately, allowing the system to achieve compact folding while maintaining precise control over each antenna's final position, thereby preserving location accuracy.
2Ease of operation
If multiple actuators are used to control the folding mechanism, then the radar system can be folded, but synchronization problems cause contraction and locking
Solution Approach 1:
Multiple actuator control functions are merged into a single centralized control system. The control unit coordinates all actuators to move in synchronization, ensuring that all segments of the foldable mechanism move together uniformly. This eliminates the contraction and locking problems that arise from asynchronous actuator operation while maintaining the folding capability.
3Adaptability or versatility
If multiple degrees of freedom are used in the foldable mechanism, then the radar system can be folded, but false data is generated due to negative impact on signal repeatability
Solution Approach 1:
Different parts of the foldable mechanism are assigned different degrees of freedom based on their specific functional requirements. The first antenna may have rotational degrees of freedom while the second antenna has different movement capabilities. This localized optimization allows each antenna to achieve its required positioning flexibility while maintaining signal repeatability and preventing false data generation.
