Solution Overview

Problem

Existing information processing apparatuses lack an efficient method to control the turning on and off of light-emitting units based on both communication status with external apparatuses and start-up status, leading to incomplete notification of abnormalities during the power-on period.

Innovation Solution

Incorporating a communication unit to communicate with external apparatuses and a control unit that turns on and off the light-emitting unit based on the start-up status, specifically using a LAN controller to manage LED lighting control after communication with an external apparatus has been established, ensuring accurate notification of abnormalities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the LAN controller controls the LED lighting based on communication status, then the communication status can be notified, but the start-up status cannot be notified after communication is established

Engineering Contradiction:
Improvenotification completenessVSAvoidcontrol system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent makes the LAN controller perform multiple functions: both communication control and LED lighting control. By enabling the LAN controller to control the LED in addition to its communication function, the system eliminates the need for a separate voltage monitoring circuit, thereby notifying both communication status and start-up status through the same LED indicator without increasing device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the LED lighting control function with the LAN controller. Instead of having separate circuits for communication status notification and start-up status notification, the system merges these functions into a single LED control mechanism managed by the LAN controller, simplifying the overall system architecture while maintaining complete status notification

Inventive Principle:
Principle #5Merging (Combining)

2Loss of information

If a separate voltage monitoring circuit is used to control LED for start-up status, then start-up status can be notified, but device complexity increases

Engineering Contradiction:
Improvestart-up status notificationVSAvoidcircuit complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The LAN controller is designed to perform multiple functions including both communication management and LED lighting control for status indication. This multi-functionality eliminates the need for a separate voltage monitoring circuit, allowing start-up status notification while maintaining simple device architecture

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent extracts the LED lighting control function from the traditional voltage monitoring circuit and transfers it to the LAN controller. This extraction allows the system to use the existing LAN controller capabilities for dual purposes (communication and status indication) without adding separate monitoring circuitry

Inventive Principle:
Principle #2Taking out (Extraction)
