Solution Overview

Problem

Conventional knitting machines lack the ability to automatically delete cloth pattern data after a knitting operation, leading to potential data leakage and reputational risks if employees misuse or steal this data.

Innovation Solution

A system for dynamic production and knitting machine work management, comprising a production demand management unit, advanced scheduling management unit, cloth pattern storage unit, and manufacturing execution unit, which automatically deletes cloth pattern data when a predetermined knitting number is reached, preventing unauthorized access and data leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If cloth pattern data is stored in knitting machines for production use, then production continuity and efficiency are improved, but data security and risk of unauthorized access deteriorate

Engineering Contradiction:

Improveproduction efficiencyVSAvoiddata leakage risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by setting up automatic deletion schedules and access control mechanisms before data leakage can occur. The cloth pattern data is configured to be automatically deleted after a predetermined time period or after completing a specific number of knitting tasks, preventing employees from stealing designs before products are publicly sold.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements automatic discarding of cloth pattern data after it has served its production purpose. The manufacturing execution unit automatically deletes the data from the knitting machine table once the predetermined condition is met, ensuring that sensitive design information is not retained longer than necessary for production.

Inventive Principle:

Principle #34Discarding and recovering

2Object-affected harmful factors

If manual deletion of cloth pattern data is required after knitting operation, then data security is improved, but operational complexity and time consumption worsen

Engineering Contradiction:

Improvedata securityVSAvoidoperational complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system enables self-service by automatically managing the deletion of cloth pattern data without requiring manual intervention from workers. The manufacturing execution unit monitors knitting task completion and automatically deletes the corresponding data from the machine table, eliminating the need for employees to manually remove designs.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements feedback mechanisms where the manufacturing execution unit continuously monitors the status of knitting tasks and automatically triggers data deletion when predetermined conditions are met. This closed-loop control ensures data is deleted at the appropriate time without manual oversight.

Inventive Principle:

Principle #23Feedback

3Ease of operation

If cloth pattern data remains in machine table after production, then ease of access for production is improved, but risk of employee theft and factory reputation harm worsens

Engineering Contradiction:

Improvedata accessibilityVSAvoidreputational risk

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The system applies dynamics by making the data retention period flexible and condition-based rather than static. Cloth pattern data remains accessible in the machine table only for the duration necessary to complete specific knitting tasks or for a predetermined time period, after which it is automatically deleted. This dynamic approach balances accessibility needs with security requirements.

Inventive Principle:

Principle #15Dynamics

AI summary

The invention provides a system for performing dynamic production and knitting machine work management comprising a production demand management unit, an advanced scheduling management unit, a cloth pattern storage unit and a manufacturing execution unit. The production demand management unit receives at least one production demand data. The advanced scheduling management unit generates a production scheduling data according to working conditions of a plurality of knitting machines and the production demand data. The cloth pattern storage unit stores a plurality of knitting machine work setting data. The manufacturing execution unit controls each knitting machine to extract one of the plurality of knitting machine work setting data from the cloth pattern storage unit based on a production cloth pattern data. The knitting machine work setting data is forcibly deleted by the knitting machine when a knitting number meets a set value defined by the knitting number limiting data.
