Solution Overview

Problem

Existing feeder maintenance devices do not provide adequate information about the state of consumable parts, making it difficult for operators to determine when these parts need replacement or replenishment.

Innovation Solution

A feeder maintenance device with an attachment section for mounting feeders, a cleaning section for maintaining the feeders, and a control section that manages history information on consumable parts usage counts and measurement values, reporting their usage state to the operator through displays or audio outputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a maintenance device performs cleaning work on feeders using consumable parts, then the maintenance effectiveness is improved, but the operator cannot easily know the usage state of these consumable parts

Engineering Contradiction:
Improvemaintenance effectivenessVSAvoidconsumable part usage state information
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The control section continuously monitors the usage count and measurement values of consumable parts (cleaning liquid, filters) and provides real-time feedback to the operator through display units. This feedback mechanism enables the operator to know the current state of consumable parts, resolving the information loss problem while maintaining effective maintenance operations.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control section acts as an intermediary between the consumable parts and the operator. It manages the history information of consumable parts usage and translates this data into readable reports, bridging the gap between the physical consumable parts and the operator's knowledge of their state.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the maintenance device manages detailed history information of consumable parts, then the maintenance reliability is improved, but the device complexity increases

Engineering Contradiction:
Improvemaintenance reliabilityVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control section performs multiple functions: it controls the cleaning operations, manages the history information of consumable parts, calculates usage counts, monitors measurement values, and generates reports. By consolidating these diverse functions into a single control section, the patent achieves high maintenance reliability without proportionally increasing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A feeder maintenance device manages history information including at least one of a usage count of a consumable part or a measurement value of the consumable part used in a cleaning section, and displays information on a usage state of the consumable part as a consumable parts screen based on history information. With feeder maintenance device, information related to the consumable part can be reported to an operator. Also, with feeder maintenance device, because an operator can replace or replenish a consumable part, it is possible to perform maintenance processing of feeder more reliably.
