Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS technology is used for positioning, then continuous position determination is achieved, but positioning accuracy deteriorates in densely populated cities and obstructed environments
Solution Approach 1:
The patent introduces ground-based transceivers as intermediary elements between GPS satellites and mobile devices. These transceivers receive GPS signals and re-transmit them locally, creating a relay system that improves signal availability in obstructed environments while maintaining the continuous positioning capability provided by GPS
2Duration of action of stationary object
If GPS technology is used for positioning, then continuous position determination is achieved, but positioning accuracy deteriorates due to physical obstructions
Solution Approach 1:
The patent segments the positioning system into multiple independent components: GPS satellite signals, ground-based transceiver nodes, and mobile receivers. This segmentation allows the system to maintain continuous tracking through GPS while using local transceivers to provide accurate positioning references in obstructed environments
3Measurement precision
If RFID technology with active transceivers is used for tracking, then dynamic position determination is achieved, but system complexity increases
Solution Approach 1:
The ground-based transceivers are designed to perform multiple functions: receiving GPS satellite signals, determining their own precise positions, and serving as reference points for calculating mobile device positions. This multi-functionality reduces the need for separate systems and lowers overall system complexity
4Reliability
If GPS technology is used for positioning, then continuous position determination is achieved, but accuracy deteriorates due to signal interruption
Solution Approach 1:
The system pre-establishes a network of ground-based transceivers throughout the service area before GPS signal interruption occurs. These transceivers are positioned to provide coverage in potential signal blind spots, cushioning against future signal interruptions and maintaining positioning accuracy

Function Achieved in This Case
The ATPS achieves accurate position and velocity determination of multiple objects to within centimeters, even in congested environments, with the ability to communicate and exchange data, reducing dependency on GPS signals and enhancing navigation and collision avoidance capabilities.
Implementation Method 1
a first wireless transceiver carried by the object and transmitting a signal including time information. At least four second wireless transceivers are fixedly mounted within the space. Each of the second wireless transceivers receives the signal.
Implementation Method 2
calculates a position of the object based upon the time information and respective times at which each of the second wireless transceivers receives the signal
Data Source
AI summary
A ground based wireless system named the Autonomous Transceivers Positioning System (“ATPS”), performs complete autonomous tracking of multiple moving objects and determines position and velocity components (speed and direction) of a moving object, or the stationary position of an object. For a moving object, the ATPS provides position determination, with accuracy of several centimeters, and velocity determination with an accuracy of centimeters per second. The ATPS tracks the position of multiple objects simultaneously and continuously for as long as the object(s) reside within the workspace of the ATPS wireless system. The ATPS is expandable in its workspace continuously by allowing for tracking information to be autonomously handed over to new added sections of the ATPS. The ATPS contains RFID inspired components including advanced multiple fixed location Autonomous Wireless Interrogators (“AWIs”) within the defined workspace of the system and multiple Autonomous Wireless Responders (“AWRs”) affixed to the moving and/or stationary objects.
