Solution Overview

Problem

In ad hoc communication mode, the physical-layer transceiver of a LAN terminal operates uninterruptedly, leading to increased power consumption as it cannot determine when packets are transmitted, affecting terminals with varying data packet amounts.

Innovation Solution

A transceiver system with a communication controller that can switch between intermittent-operation and uninterrupted-operation modes, where the transceiver and communication controller operate alternately or in parallel, respectively, to manage power usage based on packet transmission rates and amounts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the physical-layer transceiver operates uninterruptedly to receive packets from multiple LAN terminals in ad hoc communication mode, then the receiving-side LAN terminal can determine packet transmission timing, but the power consumption increases significantly

Engineering Contradiction:
Improvepacket reception reliabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the transceiver operation mode adjustable between uninterrupted and intermittent modes. The system dynamically switches between continuous operation (for reliable packet reception) and intermittent operation (for power saving), allowing the terminal to adapt its reception behavior based on whether the communication partner is in ad hoc or infrastructure mode, thus resolving the contradiction between reliability and energy consumption

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameter of the transceiver from fixed continuous operation to variable operation with two states: uninterrupted mode and intermittent mode. By changing this parameter based on communication mode detection, the system achieves both reliable packet reception when needed and power savings when possible, directly addressing the technical contradiction

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the receiving-side LAN terminal works uninterruptedly at all times to detect packet transmission, then no packets are missed, but the power consumption by the physical-layer transceiver increases

Engineering Contradiction:
Improvepacket detection reliabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The system dynamically adjusts the transceiver operation based on communication mode detection. When infrastructure mode is detected, the terminal switches to intermittent operation with the transceiver stopping during periods when no packets are expected, reducing power consumption while maintaining reliability through periodic activation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The terminal performs self-service by automatically detecting the communication mode of its partner and autonomously selecting the appropriate transceiver operation mode without external control, thereby optimizing power consumption while ensuring reliable operation based on the detected scenario

Inventive Principle:
Principle #25Self-service

3Productivity

If the transceiver operates continuously in ad hoc mode to receive packets from various LAN terminals, then all transmitted packets can be received, but power consumption increases for terminals with varying data packet amounts

Engineering Contradiction:
Improvepacket reception completenessVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent changes the transceiver operational parameter from fixed continuous mode to variable mode based on detected communication patterns. By adjusting between uninterrupted and intermittent operation, the system maintains complete packet reception when necessary while reducing power consumption during periods of low or no traffic, addressing the contradiction between productivity and energy use

Inventive Principle:
Principle #35Parameter changes

AI summary

A transceiver system which can communicate a plurality of linked partners, and the increase in power consumption by the transceiver system can be minimized. The transceiver system includes a transceiver, and a communication controller. The transceiver is capable of performing transmitted and received data communication with terminal devices. The communication controller is capable of controlling the memory transfer of transmitted and received data. The transceiver system can be set to an operation mode selected from among intermittent- and uninterrupted-operation modes. In the intermittent-operation mode, the transceiver and the communication controller work alternately, whereas in the uninterrupted-operation mode, the transceiver and the communication controller works in parallel. The operation mode of the transceiver system is set according to unique identification data of terminal devices. In a working period of the communication controller in the intermittent-operation mode, the operation of the transceiver is stopped by the control signal.
