Solution Overview

Problem

In communication systems without a terminal acting as a server, the system cannot operate appropriately due to the lack of a terminal having floor control, leading to inefficiencies in data transmission and resource management.

Innovation Solution

A method where terminals in a group can request and determine transmission authority among themselves, using priority and random values to manage data transmission, even in the absence of a central server, ensuring continuous operation and efficient resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If terminals operate without a central server, then system autonomy and adaptability improve, but coordination efficiency and resource management deteriorate

Engineering Contradiction:

Improvesystem autonomyVSAvoidcoordination efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

Terminals autonomously determine transmission authority by monitoring their own transmission states and responding to floor request messages from other terminals, eliminating the need for centralized server control while maintaining coordinated operation

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Terminals continuously monitor transmission states and exchange floor request/grant messages to dynamically adjust transmission authority allocation, creating a self-regulating system that maintains coordination efficiency without centralized control

Inventive Principle:

Principle #23Feedback

2Reliability

If distributed floor control is implemented among terminals, then system reliability improves, but control complexity increases

Engineering Contradiction:

Improvesystem reliabilityVSAvoidcontrol complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The floor control function is segmented and distributed to individual terminals, where each terminal independently monitors transmission states and processes floor requests, enhancing system reliability through decentralization while managing complexity through modular design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of a central server allocating floor control, the inversion approach allows terminals to autonomously determine and manage their own transmission authority, with control emerging from bottom-up terminal interactions rather than top-down server directives

Inventive Principle:

Principle #13The other way round (Inversion)

3Productivity

If terminals autonomously determine transmission authority, then resource allocation efficiency improves, but communication overhead increases

Engineering Contradiction:

Improveresource allocation efficiencyVSAvoidcommunication overhead

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

Terminals exchange floor request and grant messages only when transmission authority needs to be allocated or transferred, avoiding continuous communication overhead while ensuring efficient resource allocation occurs at critical moments

Inventive Principle:

Principle #16Partial or excessive action
