Solution Overview

Problem

Conventional methods for detecting abnormalities in input/output (I/O) devices in computer systems are slow and inefficient, often requiring dedicated monitoring functions and causing system shutdowns when abnormalities are detected, and they struggle to quickly identify issues in multiple connected I/O devices.

Innovation Solution

An input/output connection device that generates and transmits inspection packets with unique tags, allowing for rapid detection of abnormalities by analyzing response packets, thereby enabling quick identification of I/O device issues without the need for dedicated monitoring functions and preventing system shutdowns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If conventional passive detection methods are used, then system resources are conserved, but abnormality detection speed is slow

Engineering Contradiction:
Improveabnormality detection speedVSAvoiddetection system complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by periodically transmitting inspection packets to I/O devices before actual abnormalities occur. The I/O connection device proactively sends test packets containing unique tags to I/O devices at predetermined intervals, enabling early detection of device failures without waiting for actual operational issues.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where I/O devices respond to inspection packets with acknowledgment packets containing their device tags. The I/O connection device analyzes these response packets to determine whether I/O devices are operating normally, creating a closed-loop detection system that provides continuous status monitoring.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If dedicated monitoring functions are installed for each I/O device, then detection accuracy improves, but device complexity increases

Engineering Contradiction:
Improveabnormality detection precisionVSAvoidmonitoring function complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The I/O connection device serves multiple functions: it acts as both a data transmission hub and an abnormality detection system. By utilizing the existing communication infrastructure between the I/O connection device and I/O devices, the system achieves precise monitoring without requiring separate dedicated monitoring hardware for each device.

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

Solution Approach 2:

The monitoring function is merged with the data transmission function of the I/O connection device. The same communication channels and processing units used for normal data operations are also employed for transmitting inspection packets and analyzing device status, eliminating the need for separate monitoring infrastructure.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If active detection methods are implemented, then abnormality detection speed improves, but system resources are consumed

Engineering Contradiction:
Improvesystem reliabilityVSAvoidsystem resource consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic action by transmitting inspection packets at predetermined intervals rather than continuously. This approach maintains system reliability through regular monitoring while reducing resource consumption compared to continuous detection methods. The inspection frequency can be adjusted based on system requirements and device criticality.

Inventive Principle:
Principle #19Periodic action

AI summary

An input/output connection device includes a generating section which generates an inspection packet that has a tag that uniquely identifies the packet, a transmitting section which transmits the inspection packet to the input/output device, a receiving section which receives a packet, a first determining section which determines, on the basis of a tag of the packet received by the receiving section, whether or not the received packet is a packet transmitted in response to the inspection packet transmitted by the transmitting section, and a second determining section which analyzes the received packet and determines whether or not the input/output device is normal when the first determining section determines that the received packet is the packet transmitted in response to the inspection packet.
