Solution Overview

Problem

The aggregation chip in foldable electronic devices operates in a high-speed transmission mode with high power consumption most of the time, leading to unnecessary power waste and reduced battery endurance due to low utilization of high-speed signals.

Innovation Solution

Implement a control system with a monitoring module to detect high-speed signals, switching the aggregation chip to a high-speed transmission mode only when needed and reverting to a low-power mode otherwise, optimizing power consumption based on actual service requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the aggregation chip operates in high-speed transmission mode all the time, then signal transmission requirements (high rate, low latency) are met, but power consumption increases significantly

Engineering Contradiction:
Improvesignal transmission rateVSAvoidpower consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The aggregation chip dynamically switches between high-speed transmission mode and low-power mode based on real-time detection of signal transmission requirements. The monitoring module continuously monitors whether high-speed signal transmission is needed, and the switching module adjusts the operating mode accordingly, making the system adaptive rather than static

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The operating parameters of the aggregation chip (transmission speed, power consumption level) are changed based on actual service requirements. When high-speed signal transmission is detected, the chip operates in high-speed mode with corresponding parameters; when not needed, it switches to low-power mode with adjusted parameters to reduce energy consumption

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the aggregation chip is designed according to maximum application specifications, then high-speed signal transmission requirements are met, but power consumption increases for low-speed signals

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

Solution Approach 1:

Instead of always operating at maximum capacity (excessive action), the aggregation chip uses partial action by operating in high-speed mode only when high-speed signal transmission is actually needed. For low-speed signals, it operates in low-power mode, avoiding the excessive power consumption that would result from always using maximum specifications

Inventive Principle:
Principle #16Partial or excessive action

3Duration of action of moving object

If the aggregation chip operates without loads for large amounts of time, then battery endurance should improve, but unnecessary power waste occurs due to high standby consumption

Engineering Contradiction:
Improvebattery enduranceVSAvoidpower waste
Core Design Contradiction:
Duration of action of moving objectVSLoss of energy

Solution Approach 1:

The aggregation chip implements periodic monitoring of signal transmission requirements and periodically switches between operational modes. The monitoring module continuously detects whether high-speed signals are needed, and the switching module periodically adjusts the operating mode, creating a rhythmic pattern of high-power and low-power states that reduces overall energy waste while maintaining battery endurance

Inventive Principle:
Principle #19Periodic action

AI summary

This application provides a control system and control method for an aggregation chip, and an electronic device. The control system includes: a monitoring module, configured to monitor a to-be-transmitted signal of the aggregation chip; a switching module, configured to switch the aggregation chip from a low-power mode to a high-speed transmission mode when the monitoring module detects a to-be-transmitted high-speed signal, where power consumption in the low-power mode is lower than that in the high-speed transmission mode; and the aggregation chip, configured to transmit the high-speed signal in the high-speed transmission mode. The control system provided in this application enables the aggregation chip to operate in the low-power mode. The low-power mode may be, for example, a sleep mode or a low-speed transmission mode used to transmit low-speed signals. This effectively resolves a problem of unnecessary power waste of the aggregation chip, to enhance battery endurance of the electronic device.
