Solution Overview

Problem

Information processing systems face challenges in preventing output apparatuses from starting operations in abnormal states, especially when decompression errors occur during data transmission, leading to potential errors in printed output.

Innovation Solution

An information processing system that acquires and compresses data, determines the presence of abnormalities in compressed data before completing communication with the output apparatus, and repeats the data acquisition and compression process until the output apparatus is ready to operate, ensuring that only error-free data is processed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data compression is performed before communication with output apparatus, then data transmission efficiency is improved, but data integrity may deteriorate due to compression abnormalities

Engineering Contradiction:

Improvedata transmission efficiencyVSAvoiddata integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by performing abnormality determination on compressed data before communication with the output apparatus begins. The controller determines whether compressed data has abnormalities in advance, and only transmits data that passes this check, thereby preventing corrupted data from reaching the output device while maintaining compression efficiency.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by creating a closed-loop system where compressed data is evaluated for abnormalities, and transmission decisions are made based on this evaluation. The controller uses the abnormality determination results to feedback control the transmission process, ensuring only valid compressed data is sent to the output apparatus.

Inventive Principle:

Principle #23Feedback

2Speed

If abnormality determination is performed after communication starts, then processing speed is improved, but output apparatus may operate with abnormal data

Engineering Contradiction:

Improveprocessing speedVSAvoidoutput quality

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

3Manufacturing precision

If decompression error detection is implemented, then output quality is improved, but system complexity increases

Engineering Contradiction:

Improveoutput qualityVSAvoidsystem complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical error detection systems with a software-based abnormality determination function in the controller. Instead of using separate hardware decompression error detection mechanisms, the controller performs logical determination of data abnormalities through software processing, thereby reducing hardware complexity while maintaining output quality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An information processing system includes a processor configured to: acquire data; compress the data; before completion of communication with an output apparatus, finish determination as to whether compressed data has an abnormality, the compressed data being obtained through compression of the data; and in response to presence of an abnormality in the compressed data, perform again the data acquisition and the data compression until the output apparatus starts operation.
