Solution Overview

Problem

Existing product inspection systems, such as those described in PTL 1, have a limited scope and cannot ensure accurate and reliable inspection results for inspection items that require information beyond video data, such as confirmation of normal response to specific operations.

Innovation Solution

A product inspection system comprising an inspection information collecting unit, an inspection time acquisition unit, a recording unit, and a display control unit that collects, records, and displays inspection information, including video, operation, and response data, along with accurate time stamps, allowing for comprehensive and reliable inspection results across various inspection items.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If video data is used for inspection, then visual inspection can be performed, but the inspection scope is limited to specific items and cannot handle operations requiring additional information

Engineering Contradiction:
Improveinspection scopeVSAvoidinformation completeness
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The inspection information collecting unit is designed to collect multiple types of inspection information including video data, operation data, and response data through a unified collection mechanism. This multi-functional approach enables the system to handle various inspection items beyond just visual inspection, such as operational response verification, thereby expanding the inspection scope while maintaining information completeness

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

2Reliability

If inspection information is collected and recorded with time stamps, then accurate and reliable inspection results can be ensured, but the system complexity increases

Engineering Contradiction:
Improveinspection result reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system merges the collection of diverse inspection information (video, operation, response data) and the acquisition of time stamps into a unified collection process. The inspection information collecting unit simultaneously gathers all types of inspection information and their corresponding time stamps, then records them together in the recording unit. This integration reduces system complexity by avoiding separate collection and recording mechanisms for each data type while maintaining high reliability through comprehensive data capture

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The product inspection system comprises an inspection information collecting unit which collects inspection information acquired from an inspection target, an inspection time acquisition unit which acquires an inspection time that the inspection information was acquired, a recording unit which mutually associates and records the inspection information collected by the inspection information collecting unit and the inspection time acquired by the inspection time acquisition unit, and a display control unit which displays the inspection information recorded in the recording unit on a display terminal.
