Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for drones and other moving objects are vulnerable to electronic interference such as jamming and electronic warfare, which compromises the accuracy of position control and increases the risk of collisions.
Innovation Solution
A communication system that utilizes optical signals to transmit position coordinates between moving objects, using display units to project patterns that are photographed and deciphered by image pickup units to control the position of other objects, ensuring resistance to jamming and electronic warfare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If radio-signal communication is used for position control, then communication speed is enhanced, but the system becomes vulnerable to jamming and electronic warfare
Solution Approach 1:
The patent replaces radio-signal communication (electromagnetic field-based) with optical communication (light-based). The display unit projects optical patterns that encode position information, and the image pickup unit captures these patterns. This substitution of communication medium from radio waves to light waves fundamentally resolves the vulnerability to jamming while maintaining communication functionality.
Solution Approach 2:
The patent introduces optical patterns as an intermediary carrier for position information. Instead of directly transmitting radio signals, the system encodes position data into visual patterns that are projected and captured. This intermediary approach allows position communication to occur through a medium (light) that cannot be jammed in the traditional sense, while still conveying the necessary control information.
2Reliability
If optical signals are used for position communication, then resistance against jamming is improved, but device complexity increases
Solution Approach 1:
The patent leverages the universality of optical components by using a display unit (which can be any type of display device) and an image pickup unit (which can be any type of camera or sensor). These components serve multiple functions: they are standard electronic devices already present in many systems, and they enable optical communication without requiring specialized jamming-resistant hardware. This multi-functionality approach reduces overall system complexity.
Solution Approach 2:
The patent uses copying by encoding position information into visual patterns that can be captured and decoded. Instead of complex direct optical transmission systems, the system creates visual copies of position data that can be easily transmitted and received using standard imaging equipment. This copying approach simplifies the communication system while maintaining reliability.

AI summary
First and second movers can make communication with each other by means of a communication system in which a signal-receiving unit of the first mover receives from a satellite a signal indicative of a position coordinate of itself, a control unit of the first mover makes a pattern indicative of a position coordinate of the first mover, a display unit of the first mover displays the pattern, an image pickup unit of the second mover photographs the pattern, and a control unit of the second mover deciphers the thus photographed pattern to thereby control a position of the second mover in accordance with the thus deciphered pattern.
