Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional signaling technologies are used for determining relative positioning, then the system can operate with existing infrastructure, but the accuracy deteriorates in environments with interference or limited coverage
Solution Approach 1:
The patent employs a multi-technology signaling approach where the system can switch between or combine different signaling technologies (e.g., Wi-Fi, Bluetooth, cellular, ultra-wideband) depending on the environmental conditions. This multi-functionality enables the system to maintain positioning accuracy across diverse environments including areas with interference or limited coverage, directly resolving the contradiction between reliability and environmental adaptability
2Loss of energy
If traditional signaling technologies are used for positioning, then the system structure remains simple, but power consumption increases
Solution Approach 1:
The patent implements dynamic signaling technology selection where the system automatically adjusts which technologies to use based on real-time conditions such as signal strength, available coverage, and power constraints. This dynamic adaptation allows the system to minimize power consumption by selecting the most efficient available technology while maintaining positioning accuracy, addressing the contradiction between energy efficiency and system complexity
3Measurement precision
If traditional signaling technologies are used for positioning, then the implementation is straightforward, but interference from other signals causes inaccuracies
Solution Approach 1:
The patent introduces signal processing intermediaries and filtering mechanisms that distinguish between desired positioning signals and interfering signals from other sources. By using multiple signaling technologies with different frequency characteristics and implementing advanced signal processing, the system can filter out harmful interference while maintaining precise positioning measurements, resolving the contradiction between measurement precision and susceptibility to signal interference
