Feeding Device Notification Control for Added-Target Reliability

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The feeding device may fail to feed due to the cleaning unit being unable to perform its function when additional feeding targets are added to the loading unit before the existing targets are exhausted, leading to potential feeding failures.

Innovation Solution

A control device is implemented to perform notification control via a display unit, prompting the user to remove the feeding targets from the loading unit when additional targets are added, ensuring the cleaning unit can effectively clean the feeding unit before further operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cleaning unit operates automatically when the feeding target is exhausted from the loading unit, then the feeding unit is cleaned to maintain feeding function, but the cleaning cannot be performed if additional feeding targets are added before the existing targets are exhausted, causing feeding failure

Engineering Contradiction:

Improvefeeding functionVSAvoidoperation condition

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The control device monitors the state of the loading unit and triggers notification control when additional feeding targets are detected. This feedback mechanism ensures the user is alerted to remove existing targets before new ones are loaded, allowing the cleaning unit to operate properly and maintain feeding reliability.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary notification control to alert the user before the cleaning operation can be performed. By notifying the user in advance when additional targets are added, the system ensures the user removes existing targets beforehand, enabling the cleaning unit to function correctly without causing feeding failures.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the notification control is implemented to prompt users to remove feeding targets, then feeding failures are suppressed, but the device complexity increases due to additional control mechanisms

Engineering Contradiction:

Improvefeeding operationVSAvoidcontrol mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The notification control system operates autonomously by automatically detecting when additional feeding targets are added and triggering appropriate notifications without requiring user intervention in the detection process. This self-service approach improves reliability while minimizing the increase in operational complexity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The control device integrates multiple functions including monitoring, detection, notification control, and coordination with the cleaning unit into a single multi-functional system. This universal approach enhances feeding reliability through comprehensive control while avoiding the need for separate dedicated components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A control device includes a processor configured to perform, in a feeding device including a feeding unit that feeds out a feeding target loaded on a loading unit and a cleaning unit that cleans the feeding unit in a state where the feeding target is exhausted from the loading unit, notification control of issuing notification to prompt a user to take out the feeding target from the loading unit on a notification unit in a case where an addition state in which the feeding target is added to the loading unit occurs before the feeding target is fed out and exhausted from the loading unit.
