Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication apparatuses face inefficiencies in power management, as they either remain in a power-on state unnecessarily or shift to power-on state when not required, due to lack of detailed control over access conditions for automatic power-off and power-on functions, especially in scenarios involving remote use screens and automatic data requests.

Innovation Solution

A communication apparatus with a receiving unit, shifting unit, and control unit that selectively delays or executes state shifts based on specific conditions, such as user operation, job submissions, and error states, to manage power consumption by distinguishing between reloading target and non-reloading target screens.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the communication apparatus delays execution of the shifting process from power-on state to power-off state when receiving any request for data, then the power-on state is kept longer, but the apparatus remains in power-on state unnecessarily when the request is automatically repeated without user operation

Engineering Contradiction:

Improveresponsiveness to user requestsVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by making the power management behavior dependent on the specific type of request received. The control unit distinguishes between requests for predetermined screens (where power-on state is delayed) and requests for other screens (where automatic power-off is not delayed), creating different power management qualities for different access scenarios.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements dynamic power management by adjusting the automatic power-off timing based on the nature of the received request. The control unit dynamically decides whether to delay the power-off transition, making the power state management flexible and adaptive to different access conditions rather than following a fixed rule.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the communication apparatus automatically shifts from power-off state to power-on state when accessed, then the apparatus is ready to respond to user operations, but the apparatus shifts to power-on state even when the access is automatic and user operation is not intended

Engineering Contradiction:

Improvereadiness for user operationsVSAvoidpower consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by making the automatic power-on behavior dependent on the specific type of request received. The control unit distinguishes between requests for predetermined screens (where automatic power-on is suppressed) and requests for other screens (where automatic power-on is executed), creating different power management qualities for different access scenarios.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements dynamic power management by adjusting the automatic power-on timing based on the nature of the received request. The control unit dynamically decides whether to execute the power-on transition, making the power state management flexible and adaptive to different access conditions rather than following a fixed rule.

Inventive Principle:

Principle #15Dynamics

3Speed

If the communication apparatus keeps the power-on state when receiving requests for predetermined screens, then user operations can be performed without delay, but power consumption increases when the apparatus should remain in power-off state

Engineering Contradiction:

Improveresponse speed for user operationsVSAvoidpower consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by making the power state decision dependent on the specific type of request received. The control unit distinguishes between requests for predetermined screens (where power-on state is maintained for fast response) and requests for other screens (where power-off state is allowed to save energy), creating different power management qualities for different access scenarios.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements dynamic power management by adjusting the power state transition timing based on the nature of the received request. The control unit dynamically decides whether to delay the power-off transition or execute it, making the power state management flexible and adaptive to different access conditions rather than following a fixed rule.

Inventive Principle:

Principle #15Dynamics

AI summary

A communication apparatus includes a control unit configured, when the communication apparatus is in a first state and when a receiving unit receives a request, from an external device, for data for a predetermined screen that is among a plurality of screens for remotely using the communication apparatus, not to execute control for delaying execution of a shifting process, and when the communication apparatus is in the first state and when the receiving unit receives a request, from the external device, for data for display of a screen that is not the predetermined screen and that is among a plurality of screens for remotely using the communication apparatus, to execute the control for delaying execution of the shifting process.
