Electronic Device Distance Measurement With Congestion-Aware Subsections
Solution Overview
Problem
Electronic devices face challenges in accurately measuring distances due to collisions between external devices when multiple response messages are received during distance measurement, leading to congestion and increased power consumption.
Innovation Solution
The electronic device identifies the number of response messages and determines congestion levels in each distance measurement subsection, broadcasting information to adjust the distance measurement section for external devices to transmit responses in less congested areas, thereby reducing collisions and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple external electronic devices transmit response messages simultaneously in the same distance measurement section, then the distance measurement can be performed in parallel, but collisions occur between response messages leading to measurement failure
Solution Approach 1:
The distance measurement section is divided into multiple distance measurement subsections. Each external electronic device is assigned to transmit response messages in different subsections, thereby segmenting the transmission resources and avoiding collisions while maintaining parallel measurement capability
Solution Approach 2:
The system dynamically determines congestion levels in each distance measurement subsection and adjusts the assignment of external devices to subsections based on real-time congestion information, enabling adaptive resource allocation that prevents collisions while maximizing measurement efficiency
2Measurement precision
If the electronic device broadcasts distance measurement messages to all external devices, then comprehensive distance measurement can be achieved, but congestion occurs in specific sections leading to increased power consumption
Solution Approach 1:
The system identifies congestion levels in specific distance measurement subsections and directs external devices to transmit response messages in less congested subsections. This local optimization reduces unnecessary transmissions in congested areas, lowering power consumption while maintaining comprehensive measurement coverage
Solution Approach 2:
The electronic device monitors response message reception in each distance measurement subsection, determines congestion levels, and broadcasts congestion information back to external devices. This feedback mechanism enables external devices to adjust their transmission behavior, reducing power consumption by avoiding congested sections
