Solution Overview

Problem

The existing loom monitoring systems in weaving mills require manual and time-consuming processes for setting and correlating unique IP addresses with loom layout maps, especially when dealing with multiple looms, and are prone to errors.

Innovation Solution

A system utilizing a DHCP server to automatically assign and manage fixed IP addresses, correlating them with a loom layout map, eliminating the need for manual input and enabling easy correlation of IP addresses with the layout, even for operators without sophisticated network knowledge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual IP address setting is performed by operators, then each loom computer can be assigned a unique IP address, but the process consumes significant time and manpower especially when there are many looms

Engineering Contradiction:

Improveunique IP address assignmentVSAvoidtime for IP address setting

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system enables automatic self-service IP address assignment where the host computer automatically assigns IP addresses to loom computers based on their physical layout, eliminating the need for manual operator input and significantly reducing the time required for IP address configuration

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The host computer pre-configures IP address assignment rules based on the loom layout map before actual assignment, preparing the assignment sequence and correlation data in advance to streamline the IP address distribution process

Inventive Principle:

Principle #10Preliminary action

2Reliability

If manual IP address input is performed by operators, then IP addresses can be assigned to loom computers, but errors occur during input and correction is required

Engineering Contradiction:

ImproveIP address assignmentVSAvoidIP address input accuracy

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The automatic assignment system eliminates manual input operations that cause errors, using the host computer to automatically correlate and assign IP addresses based on the pre-stored loom layout map, ensuring high precision without human intervention

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system establishes automatic feedback mechanisms where the host computer verifies IP address assignment results and correlates them with the loom layout map, automatically detecting and correcting any assignment errors without requiring manual verification

Inventive Principle:

Principle #23Feedback

3Reliability

If operators correlate IP addresses with loom layout map, then accurate data transfer can be achieved, but the correlation process is time-consuming and requires sophisticated knowledge

Engineering Contradiction:

Improvedata transfer accuracyVSAvoidIP address correlation operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The host computer automatically performs the correlation between IP addresses and the loom layout map by matching assigned IP addresses with corresponding loom positions in the pre-stored layout data, eliminating the need for operators to manually correlate and reducing the operation to simple button presses

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The loom layout map is pre-stored in the host computer with position information, enabling automatic correlation with assigned IP addresses without requiring operators to manually match or interpret layout information

Inventive Principle:

Principle #10Preliminary action

4Reliability

If manual IP address setting is performed, then fixed IP addresses can be assigned to loom computers, but the process requires sophisticated network knowledge

Engineering Contradiction:

Improvefixed IP address assignmentVSAvoidnetwork knowledge requirement

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system automates the entire fixed IP address assignment process through the host computer, which automatically assigns addresses and correlates them with the loom layout map, reducing the operator's role to initiating the process and eliminating the need for sophisticated network knowledge

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The host computer acts as an intermediary between the operators and the network configuration process, handling all complex IP address assignment and correlation tasks, thereby shielding operators from technical complexity while ensuring reliable fixed IP address assignment

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A loom monitoring system includes loom computers and a host computer connected to the loom computers through a network. Each loom computer acquires a temporary IP address from a DHCP server when a fixed IP address is not set for the loom computer and requests the host computer to transmit a fixed IP address using the temporary IP address. The host computer assigns a fixed IP address to the loom computer that transmitted the assignment request signal and correlates the fixed IP address with a loom layout map. The loom computers each transmit an acquisition completion signal to the host computer using the fixed IP address in a designated order based on the loom layout map. The host computer correlates the fixed IP address of each loom computer with the loom layout map in accordance with the designated order.
