Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wireless communications systems in factories and warehouses face challenges in efficiently managing dynamic changes in communication requirements, such as low latency and varying communication frequencies, due to fixed policies that cannot adapt quickly to changing conditions, leading to unstable communications and inefficient use of frequency resources.

Innovation Solution

A communications network system with a controller that acquires data and wireless environment information, generates and manages communication policies, and includes policy agent units in wireless systems to detect status changes and adjust policies without prior inquiry, allowing for flexible control of transmission parameters like frequency, route, and antenna directivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fixed communication policies are configured on the controller side and transmitted to wireless systems, then system stability and centralized control are improved, but the ability to respond to dynamic changes in communication requirements deteriorates

Engineering Contradiction:

Improvecommunication stabilityVSAvoidresponse to dynamic changes

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic communication policies that can be automatically adjusted based on real-time wireless environment conditions. The system transitions from static, pre-configured policies to dynamic policies that adapt to changing communication requirements, latency demands, and channel conditions through continuous monitoring and automated adjustment mechanisms.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The wireless systems are equipped with autonomous capabilities to self-adjust communication parameters based on local environmental conditions and performance metrics. Each wireless system can independently modify its communication behavior without requiring constant controller intervention, enabling rapid response to dynamic changes while maintaining overall system coordination.

Inventive Principle:

Principle #25Self-service

2Speed

If communication policies are updated in real-time to meet low latency requirements, then responsiveness to changing conditions is improved, but system complexity and control overhead increase

Engineering Contradiction:

Improvepolicy update speedVSAvoidcontrol system complexity

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The patent divides the communication policy management into segmented, modular components that can be independently updated and adjusted. Different policy parameters (transmission power, modulation scheme, coding rate) can be modified separately based on specific communication needs, reducing the complexity of managing entire policy sets as monolithic units.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system pre-configures multiple communication policies with different parameter settings before runtime. When dynamic adjustment is needed, the system selects from pre-prepared policies or makes incremental adjustments to existing policies, rather than generating completely new policies from scratch, thereby reducing update time and computational complexity.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If multiple wireless systems operate independently with their own communication parameters, then system autonomy is improved, but overall frequency resource utilization and optimization deteriorate

Engineering Contradiction:

Improvesystem autonomyVSAvoidfrequency resource efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent implements a universal communication policy framework that can be applied across multiple wireless systems while allowing local adaptations. The controller manages a set of standardized communication policies that can be dynamically assigned to different wireless systems based on their specific needs and current environmental conditions, achieving both autonomy and resource efficiency.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system incorporates feedback mechanisms where wireless systems report their communication performance and environmental conditions to the controller. The controller uses this feedback information to optimize frequency resource allocation and adjust communication policies across the network, ensuring efficient resource utilization while maintaining system autonomy through distributed decision-making.

Inventive Principle:

Principle #23Feedback

AI summary

A communications network system includes a control unit, one or more wireless systems, and application equipment. The control unit acquires information about data that the application equipment communicates via the wireless systems, and acquires information about a wireless environment that has an impact on communications by the wireless systems. The control unit generates a plurality of communications policies that are delivered to the wireless systems, and manages the communications policies that are executed on the wireless systems. The wireless systems store the plurality of communications policies delivered from the control unit, and detect the status of communications, change the communications policies based on the detection result, and control information about data that the application equipment communicates via the wireless systems.
