Solution Overview

Problem

Existing packaging and weighing systems experience significant downtime due to issues like clogging and product deficiencies, leading to inefficient production.

Innovation Solution

A remedy judging system that includes a weight checking device and a judgment unit to identify areas for remedy in the weighing device based on 'underweight' and subsequent checking results, using determination patterns to minimize downtime.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the packaging operation is stopped due to consecutive underweight products, then the weighing accuracy is improved, but the productivity decreases due to increased downtime

Engineering Contradiction:
Improveweighing accuracyVSAvoidproduction efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The system performs preliminary analysis of weight checking results to identify determination patterns before stopping production. By detecting patterns like consecutive underweight products or alternating underweight/overweight sequences, the system can take preliminary remedial actions or prepare for stopping only when necessary, rather than stopping immediately at the first sign of weight issues.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors weight checking results and provides feedback through the judgment unit to identify areas for remedy in the weighing and packaging devices. This feedback mechanism allows for real-time adjustments and targeted remediation, reducing the need for complete production stoppages while maintaining weighing accuracy.

Inventive Principle:
Principle #23Feedback

2Manufacturing precision

If the packaging operation is stopped frequently to maintain product weight quality, then the manufacturing precision is improved, but the loss of time increases due to repeated stoppages

Engineering Contradiction:
Improveproduct weight qualityVSAvoiddowntime
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system establishes determination patterns in advance that define when stoppages are necessary versus when continuous operation can be maintained. By pre-defining criteria such as the number of consecutive underweight products required to trigger a stop, the system minimizes unnecessary stoppages while ensuring product quality standards are met.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The judgment unit automatically analyzes weight checking results and identifies areas for remedy without requiring constant human intervention. The system serves itself by continuously monitoring its own performance and making autonomous judgments about when production should continue or stop, reducing downtime associated with manual quality checks and decisions.

Inventive Principle:
Principle #25Self-service

AI summary

[Problem] To enable a reduction in downtime. [Solution] A remedy judging system (100) includes a weight checking device (3) and a judgment unit (6). The weight checking device (3) checks the weight of weighed product discharged from a weighing device. The judgment unit (6) makes a judgment relating to remedies for the weighing device on the basis of "correct weight," "overweight," and "underweight" checking results, relative to a predetermined weight serving as a norm, obtained by the weight checking device (3). The judgment unit (6) makes the judgment on the basis of determination patterns having an "underweight" checking result and at least one checking result that consecutively follows the "underweight" checking result.
