Solution Overview

Problem

In manufacturing environments, particularly on assembly lines, operators face challenges in quickly and accurately identifying and selecting the correct parts due to similarities in part features, leading to delays and additional costs when incorrect parts are installed, as visual identification is often relied upon in a two-step process.

Innovation Solution

A wireless barcode processing device is integrated into a glove, allowing operators to scan barcodes on parts using a scanner, with a processor for data processing and comparison, and an indicator for real-time notifications, enabling immediate matching or non-matching alerts to ensure correct part selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If visual identification is used to identify parts, then the operator can select parts based on appearance, but errors occur due to similar part features leading to incorrect selection

Engineering Contradiction:
Improvepart selectionVSAvoidpart selection accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces the manual visual identification process with an automated optical scanning system. The barcode scanner automatically reads and compares part identifiers, eliminating human visual errors caused by similar part appearances. This substitution of mechanical/optical automation for manual visual inspection directly resolves the contradiction between ease of operation and selection accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system provides immediate feedback through audible and visual signals indicating whether the scanned part matches the required part. This real-time feedback mechanism allows operators to instantly verify correct part selection, preventing errors from propagating and enabling immediate correction if mismatches occur.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If a two-step visual identification process is used, then parts can be identified and selected, but time is lost due to the multi-step process and potential corrections

Engineering Contradiction:
Improvepart identification processVSAvoidpart selection time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary action by pre-loading the required part identifier into the scanner before the operator begins searching for parts. This allows the scanning and comparison process to be completed in a single pass, eliminating the need for a second verification step and reducing total identification time while maintaining accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

By replacing the manual two-step visual identification process with automated barcode scanning and comparison, the system consolidates multiple manual steps into a single automated operation. This substitution eliminates the time loss associated with manual verification and potential rework.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If manual part selection is used, then operators have flexibility in choosing parts, but errors lead to delays and additional costs when incorrect parts are installed

Engineering Contradiction:
Improvepart selection flexibilityVSAvoidassembly line efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The immediate feedback system provides real-time verification of part correctness, allowing operators to maintain flexibility in part selection while ensuring accuracy. The audible and visual signals guide operators to the correct parts without restricting their ability to search through available inventory, thus maintaining adaptability while preventing productivity losses from errors.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The barcode scanning system acts as an intermediary between the operator and the part selection process. It provides the flexibility of manual searching while incorporating automated verification, serving as a mediator that combines the benefits of both manual flexibility and automated accuracy to maintain high productivity.

Inventive Principle:
Principle #24Intermediary (Mediator)
