Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems fail to dynamically adjust transmission power in response to temporal changes in communication device movement and partner situations, leading to communication congestion and throughput decline in areas with concentrated devices.
Innovation Solution
A mobile communication device and system that sets transmission power based on real-time location and movement information of communication partners, updating power settings to ensure optimal communication by correlating transmission power with receiving power and elapsed time, and adjusting power levels to prevent congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission power is increased to maintain communication coverage, then communication reliability is improved, but communication congestion occurs and throughput declines in areas with concentrated devices
Solution Approach 1:
The patent implements dynamic transmission power adjustment by continuously monitoring the number of communication devices in the communication area and adapting the transmission power accordingly. When device concentration is detected, the system dynamically reduces transmission power to prevent congestion while maintaining reliable communication with existing partners, thus resolving the contradiction between communication reliability and throughput.
Solution Approach 2:
The system changes the transmission power parameter based on the detected number of communication devices. By adjusting this key parameter in response to environmental conditions (device concentration), the system optimizes both communication reliability and overall network throughput, preventing the degradation that occurs with fixed power settings.
2Productivity
If transmission power is decreased to reduce congestion, then throughput is maintained, but communication coverage area shrinks and partners may be lost
Solution Approach 1:
The system dynamically adjusts transmission power based on real-time detection of communication partner density. When congestion is detected, power is temporarily reduced to maintain throughput; when device concentration decreases, power is increased again to restore full coverage. This dynamic adaptation prevents permanent loss of communication partners while maintaining throughput during congested periods.
3Reliability
If transmission power is adjusted frequently to respond to device movement, then communication quality is maintained, but system complexity and power consumption increase
Solution Approach 1:
The patent implements periodic detection of the number of communication devices and adjusts transmission power at these periodic intervals rather than continuously. This periodic action maintains communication quality by responding to significant changes in device concentration while avoiding the excessive complexity and power consumption associated with continuous adjustment, thus resolving the contradiction between communication quality and system complexity.
