Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous devices face challenges in avoiding collisions with other movable objects due to the lack of effective distance measurement and collision risk assessment systems, especially in environments where line-of-sight detection is obstructed.
Innovation Solution
A positioning surveillance system (PSS) using 5G cellular technology for triangulation and communication enables distance determination and risk level assessment between objects, allowing autonomous devices to adjust their speed and trajectory proactively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If line-of-sight detection methods are used for collision avoidance, then detection simplicity is improved, but detection reliability deteriorates in obstructed environments
Solution Approach 1:
The patent introduces a positioning surveillance system (PSS) as an intermediary infrastructure that uses multiple transceivers and triangulation to determine object locations. This mediator bypasses the line-of-sight limitation by using wireless signal propagation through obstacles, allowing reliable position detection without direct visual contact between autonomous devices.
2Productivity
If high speeds are used for autonomous device operation, then productivity is improved, but collision risk increases
Solution Approach 1:
The system implements continuous feedback by constantly monitoring distances between autonomous devices and communicating risk levels back to each device. This real-time feedback loop enables high-speed operation while maintaining safety, as devices receive ongoing information about potential collision risks and can adjust their trajectories accordingly.
Solution Approach 2:
The PSS proactively determines positions and calculates risk levels before collisions occur. By continuously tracking all movable objects and computing potential collision risks in advance, the system enables autonomous devices to take preliminary corrective actions (such as trajectory adjustments) before actual collision threats materialize, allowing higher operating speeds.
3Reliability
If frequent position monitoring is implemented, then collision avoidance reliability is improved, but system complexity increases
Solution Approach 1:
The patent merges the positioning and collision avoidance functions into a unified PSS infrastructure. Multiple transceivers are combined into a coordinated network that performs triangulation, and the system integrates position determination, distance calculation, and risk assessment into a single integrated framework. This consolidation reduces overall system complexity while enabling frequent monitoring.

AI summary
An example system includes a positioning surveillance system (PSS) to identify locations of objects that are movable throughout a space. The PSS is configured to identify the locations without requiring a line-of-sight between the objects. A control system is configured to determine distances based on the locations of the objects in the space and to communicate information to the objects that is based on the distances. The information is usable by the objects for collision avoidance.
