Solution Overview

Problem

Existing packet traffic arbitration (PTA) systems face challenges in prioritizing lower-power, lower-bandwidth transmissions without causing latency in higher-power, higher-bandwidth transmissions, especially in environments with high WiFi traffic.

Innovation Solution

The implementation of intelligent packet traffic arbitration, which allocates and reallocates network resources based on weighted criteria such as device properties, transmission conditions, and user profiles, to prioritize lower-power transmissions while minimizing latency in higher-power transmissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If packet traffic arbitration prioritizes lower-power transmissions, then battery life and reliability for low-power devices is improved, but latency for higher-power transmissions increases

Engineering Contradiction:

Improvereliability of lower-power transmissionsVSAvoidlatency in higher-power transmissions

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system dynamically adjusts transmission priorities based on real-time conditions. The gateway monitors network traffic patterns and device requirements, then dynamically switches between prioritizing low-power transmissions during battery-critical periods and maintaining normal priorities during high-bandwidth needs, resolving the contradiction through adaptive rather than static prioritization

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements periodic arbitration cycles where transmission priorities are reviewed and adjusted at regular intervals. During periods when low-power devices need reliability, the system periodically enables enhanced arbitration; during periods when high-power transmissions need bandwidth, it periodically switches to standard arbitration, thus managing both requirements over time

Inventive Principle:

Principle #19Periodic action

2Use of energy by moving object

If packet traffic arbitration allocates network resources to lower-power devices, then battery life is improved, but bandwidth for higher-power devices is reduced

Engineering Contradiction:

Improvebattery life of lower-power devicesVSAvoidbandwidth availability for higher-power devices

Core Design Contradiction:

Use of energy by moving objectVSQuantity of substance

Solution Approach 1:

The system applies partial prioritization rather than complete resource allocation to low-power devices. It provides enhanced arbitration only when necessary (partial action), allowing higher-power devices to retain sufficient bandwidth for their needs while still improving battery life, thus avoiding excessive resource diversion

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system changes the arbitration parameters dynamically based on network conditions and device requirements. By adjusting priority weights, time slots, and bandwidth allocation ratios as parameters, the system can optimize energy efficiency during some periods while maintaining adequate bandwidth during others, resolving the contradiction through parameter optimization

Inventive Principle:

Principle #35Parameter changes

3Productivity

If existing packet traffic arbitration is implemented, then lower-power transmissions are prioritized, but higher-power transmissions experience delays during high traffic periods

Engineering Contradiction:

Improvetransmission efficiency of lower-power devicesVSAvoidtransmission delay for higher-power devices

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The gateway continuously monitors network traffic conditions and device transmission status, using this feedback to adjust arbitration decisions in real-time. When high traffic periods are detected, the system receives feedback about congestion levels and adjusts priorities accordingly, allowing higher-power devices to get necessary attention without permanently sacrificing low-power device efficiency

Inventive Principle:
