Solution Overview

Problem

Conventional production management computer programs fail to distinguish between ordered parts and work-in-process stock parts, leading to inaccurate stock management and traceability issues for work-in-process stock parts.

Innovation Solution

A stock management device and method that issues a unique identifier for each piece of nesting data, associates it with part information, and manages work-in-process stock parts without manufacturing numbers, enabling proper identification and tracking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional production management computer programs are used to manage parts, then ordered parts can be tracked using manufacturing numbers, but work-in-process stock parts cannot be distinguished or managed accurately

Engineering Contradiction:
Improvestock status detection precisionVSAvoidpart type adaptability
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent segments the identification system by introducing a specific attribute field in the database to distinguish between ordered parts (with manufacturing numbers) and work-in-process stock parts (without manufacturing numbers). This segmentation allows the system to track different part types using appropriate identification methods for each category, resolving the inability to differentiate between part types while maintaining accurate stock management.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If work-in-process stock parts are added later in on-site determination, then flexibility in part selection is improved, but accurate stock status grasping and traceability cannot be ensured

Engineering Contradiction:
Improveon-site determination flexibilityVSAvoidstock status reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements preliminary action by pre-establishing the database structure with dedicated fields for manufacturing numbers and part identification status before any parts are processed. This preliminary setup enables the system to reliably track work-in-process stock parts as they are added during on-site determination, ensuring both flexibility in part selection and accuracy in stock status monitoring from the outset.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If nesting data includes both ordered parts and work-in-process stock parts, then sheet utilization efficiency is improved, but part distinction and individual management become difficult

Engineering Contradiction:
Improvesheet utilization efficiencyVSAvoiddata management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies local quality by implementing specific data attributes at the individual part level within the nesting data structure. Each part record contains localized quality indicators such as manufacturing number presence, part type flags, and identification status. This allows the system to efficiently manage mixed nesting data while maintaining the ability to distinguish and individually track ordered parts and work-in-process stock parts through their unique local characteristics.

Inventive Principle:
Principle #3Local quality

AI summary

A stock management device is configured to be able to execute an identifier issuance process of issuing a unique identifier for each piece of nesting data, a part information acquisition process of acquiring part information of one or more pieces of part data included in the nesting data, and an association process of associating the identifier of the nesting data with the part information of the part data included in the nesting data, in which the nesting data is able to include the part data for an ordered part having a manufacturing number and the part data for a work-in-process stock part having no manufacturing number, so that the work-in-process stock part is managed by the identifier.
