Solution Overview

Problem

Current wireless communication circuits in idle states continue to consume high power due to the need to store parameters of all channels, limiting power-saving effectiveness.

Innovation Solution

A method where the wireless communication circuit retains only the parameters of the specific channel in use and removes parameters of unused channels from storage when entering power-saving mode, allowing for increased power-down regions and reduced consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If parameters of all channels are stored in internal memory during idle state, then communication readiness is maintained, but power consumption increases

Engineering Contradiction:
Improvecommunication readinessVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent segments the channel parameters into two groups: currently used channel parameters and non-used channel parameters. This segmentation allows the system to selectively power down storage regions, maintaining only the necessary communication parameters in active memory while moving others to low-power storage, thus resolving the contradiction between maintaining communication readiness and reducing power consumption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by differentiating the power state of different memory regions. Specifically, the first memory region storing currently used channel parameters remains powered on to maintain communication readiness, while the second memory region storing non-used parameters is powered down to reduce consumption. This localized quality approach allows selective power management based on actual communication needs.

Inventive Principle:
Principle #3Local quality

2Use of energy by moving object

If circuits are disabled in idle state to save power, then power consumption decreases, but ability to receive beacon packets is compromised

Engineering Contradiction:
Improvepower consumptionVSAvoidbeacon packet reception
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent performs preliminary action by pre-storing parameters of currently used channels in a first memory region before entering idle state. This ensures that when the circuit enters low-power mode, the essential parameters for receiving beacon packets are already in place and can be quickly accessed without requiring full circuit activation, thus maintaining reliability while reducing power consumption.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements dynamic power management by transitioning memory regions between powered-on and powered-off states based on whether the corresponding channels are currently in use. This dynamic approach allows the system to adapt its power consumption level to actual communication needs, maintaining beacon packet reception capability when needed while saving power during idle periods.

Inventive Principle:
Principle #15Dynamics
