Solution Overview

Problem

Current energy management systems face challenges in efficiently managing power consumption across various devices in different control modes, particularly in transitioning between normal and power-saving modes, which affects overall system efficiency and energy usage.

Innovation Solution

An electronic apparatus with a changing unit that alters control modes, a first notification unit for normal mode operations, and a second notification unit for power-saving mode operations, utilizing a CPU for normal mode notifications and an ASIC for reduced power consumption in power-saving mode notifications, with pre-recorded data transmission to minimize CPU usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electronic apparatus operates in normal mode with frequent notifications, then the management unit receives timely updates, but the power consumption increases

Engineering Contradiction:

Improvenotification timelinessVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The notification interval is dynamically adjusted based on the control mode. In normal mode, notifications are sent at a first interval to ensure timely updates. In power-saving mode, the interval is extended to a second interval (longer than the first), reducing the frequency of notifications and thus lowering power consumption while maintaining acceptable management oversight.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The notification timing parameter is changed according to the control mode. The changing unit modifies the notification interval parameter from a first value (shorter interval) in normal mode to a second value (longer interval) in power-saving mode, optimizing the balance between notification timeliness and power consumption based on operational requirements.

Inventive Principle:

Principle #35Parameter changes

2Use of energy by moving object

If the electronic apparatus transitions to power-saving mode, then the power consumption decreases, but the notification responsiveness deteriorates

Engineering Contradiction:

Improvepower consumptionVSAvoidnotification delay

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The system dynamically adapts the notification behavior to the current control mode. When in power-saving mode, the notification interval is extended, which is acceptable because the apparatus is intentionally in a low-power state. This dynamic adjustment ensures that power consumption is reduced while the management unit is still notified within an acceptable timeframe for the given operational state.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Notifications are sent periodically at intervals that depend on the control mode. In power-saving mode, the periodic action occurs less frequently (longer interval), which reduces the cumulative power consumption over time while still providing periodic updates to the management unit, balancing responsiveness with energy efficiency.

Inventive Principle:

Principle #19Periodic action

3Loss of information

If the notification interval is shortened, then the management unit receives more frequent updates, but the power consumption increases

Engineering Contradiction:

Improveinformation update frequencyVSAvoidpower consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The notification interval parameter is adjusted based on the control mode. In normal mode, a shorter interval (first value) is used to provide frequent updates to the management unit. In power-saving mode, the interval is extended (second value, longer than the first), reducing the frequency of notifications and thereby lowering power consumption while still providing sufficient information updates for the given operational state.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The notification frequency is dynamically adjusted according to the operational state. When the apparatus is in normal mode, notifications are sent more frequently. When transitioning to power-saving mode, the notification frequency is reduced, creating a dynamic system that adapts information update frequency to match power availability and operational priorities.

Inventive Principle:

Principle #15Dynamics
