Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional indoor three-dimensional localization technologies are used, then positioning accuracy can be maintained, but infrastructure complexity and cost increase significantly
Solution Approach 1:
The patent replaces traditional infrastructure-heavy localization systems (such as Wi-Fi access points, Bluetooth beacons, or ultrasonic transmitters) with electronic labels that utilize existing radio frequency communication capabilities. This substitution eliminates the need for dedicated localization infrastructure while maintaining positioning functionality through bidirectional RF transmission and presence detection algorithms.
Solution Approach 2:
The patent uses electronic labels that replicate the localization functionality of traditional infrastructure elements without requiring actual physical infrastructure. Each electronic label acts as a virtual anchor or node, copying the positioning function of traditional systems through software-based presence detection and triangulation algorithms, thereby eliminating hardware complexity.
2Reliability
If traditional localization systems are deployed, then reliable positioning can be achieved, but setup time and cost increase
Solution Approach 1:
The patent enables electronic labels to automatically participate in the localization network without requiring manual configuration or infrastructure setup. Each label autonomously establishes bidirectional RF communications with other labels or anchor points, and the system automatically performs presence detection and position estimation, eliminating the need for technical personnel to configure traditional localization infrastructure.
Solution Approach 2:
The patent pre-configures electronic labels with necessary identification data and communication parameters before deployment. The bidirectional RF transmission capability is pre-established, allowing labels to immediately participate in localization upon deployment without requiring post-installation configuration or system calibration, thereby reducing setup time while maintaining reliability.
3Measurement precision
If line of sight requirements are imposed, then measurement accuracy improves, but adaptability to various settings decreases
Solution Approach 1:
The patent transitions from two-dimensional line-of-sight-based positioning to three-dimensional presence detection using bidirectional RF transmission. By utilizing the third dimension (signal presence/absence and transmission bidirectionality) rather than relying solely on direct visual line of sight, the system achieves accurate positioning in environments with obstacles, walls, or complex geometries where traditional line-of-sight methods fail.
Solution Approach 2:
The patent replaces optical line-of-sight requirements with radio frequency presence detection. RF signals can penetrate obstacles and reflect off surfaces, allowing the system to detect presence and estimate position without direct visual contact between transmitter and receiver, thereby enabling operation in indoor environments, warehouses, and outdoor settings with varying visibility conditions.
