Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional geo-fence establishment methods are used, then basic boundary definition is achieved, but the process becomes complex and resource-intensive in environments with multiple overlapping fences or complex shapes
Solution Approach 1:
The fence nodes automatically perform trilateration calculations and coordinate system establishment without requiring manual configuration. The system self-configures by having nodes determine their positions relative to each other through automated distance measurements and mathematical computations, eliminating the need for complex manual setup procedures.
Solution Approach 2:
The patent pre-establishes a coordinate system framework before defining actual fence boundaries. By first setting up the coordinate system and having nodes determine their positions within it, the system creates a structured foundation that simplifies subsequent fence definition, allowing complex geometries to be defined through simple vertex registration rather than complex configuration.
2Measurement precision
If precise node configuration and distance determination are implemented, then accurate geo-fence boundaries are achieved, but the process requires significant computational resources and time
Solution Approach 1:
The patent divides the geo-fence establishment process into distinct segments: first establishing the coordinate system, then having each node independently determine its position through trilateration, and finally registering vertices by simple location marker placement. This segmentation allows parallel processing of node position determinations and reduces the sequential time required compared to traditional methods that require comprehensive configuration of all parameters before boundary definition.
Solution Approach 2:
The patent introduces a coordinate system as an intermediary framework that simplifies the relationship between nodes and fence boundaries. Instead of directly configuring complex geometric relationships between nodes, the coordinate system serves as a mediator that transforms the problem into simpler position registrations within a predefined framework, reducing computational complexity and time.
3Manufacturing precision
If manual configuration of fence nodes and vertices is performed, then basic geo-fences can be established, but accurate determination of node positions and shapes becomes difficult in complex environments
Solution Approach 1:
The patent replaces manual mechanical configuration processes with automated electronic trilateration and coordinate system calculations. Instead of manually positioning and configuring nodes based on physical measurements, the system uses electronic distance measurements between nodes and automated mathematical computations to determine positions and define boundaries, significantly improving accuracy while simplifying operation.
Solution Approach 2:
The patent uses location markers as simplified copies or representations of actual fence vertices. Rather than requiring precise manual configuration of complex geometric parameters, the system uses simple location marker placements that are automatically translated into accurate vertex coordinates through the established coordinate system, making the process easier to operate while maintaining high precision.

The fence network comprises a plurality of fence nodes in communication with each other and a plurality of fence vertices defining a geographic fence. The method comprises configuring the plurality of fence nodes, setting up a coordinate system to determine a position of each fence node of the plurality of fence nodes, and, for each fence vertex, setting a location marker at a position of the fence vertex and using the location marker to register the position of the fence vertex. At least one fence vertex may be located at a position other than a position of a fence node. The plurality of fence vertices may be registered in sequential order and connected in order of registration.
