Solution Overview

Problem

The maintenance of automated fiber bundle placement apparatuses is complicated due to the presence of multiple devices and mechanisms around the conveying mechanisms, making it difficult to access and remove guidance mechanisms for cleaning and maintenance, which requires time and effort from operators.

Innovation Solution

A frame configuration with a main frame part attached to the multi-jointed robot and a detachable sub-frame part for guidance mechanisms, along with a holding mechanism to facilitate easy attachment and detachment of the sub-frame part, allowing for simplified maintenance operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple guidance mechanisms are provided around the conveying mechanisms to guide each fiber bundle, then the fiber bundle placement function is improved, but the maintenance complexity increases and accessibility for maintenance deteriorates

Engineering Contradiction:
Improvefiber bundle placement functionVSAvoidmaintenance accessibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The placing head is divided into a main body and a detachable guidance mechanism module. The guidance mechanisms (including guide rollers and S-shaped guides) are integrated into a separate module that can be detached from the main body, allowing maintenance personnel to access and maintain the conveying mechanisms without disassembling multiple individual guidance components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guidance mechanisms are extracted as a separate detachable module from the main placing head body. This module can be removed and set aside during maintenance operations, clearing the path to the conveying mechanisms and enabling easy access for cleaning and maintenance without leaving other mechanisms in the way.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If multiple individual guidance mechanisms are provided for each fiber bundle path, then the guidance function is improved, but the time and effort required for maintenance increases

Engineering Contradiction:
Improveguidance functionVSAvoidmaintenance time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The guidance mechanisms are segmented into a unified detachable module rather than remaining as separate individual components. This allows all guidance mechanisms to be removed and set aside as a single unit during maintenance, dramatically reducing the time required compared to handling multiple individual components separately.

Inventive Principle:
Principle #1Segmentation

3Productivity

If the placing head includes multiple conveying mechanisms and guidance mechanisms for multiple fiber bundles, then the productivity is improved, but the device complexity increases making maintenance difficult

Engineering Contradiction:
Improvemulti-fiber bundle placement capabilityVSAvoidmaintenance complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The placing head is segmented into a main body containing conveying mechanisms and a detachable module containing guidance mechanisms. This segmentation maintains the multi-fiber bundle placement capability while simplifying maintenance by allowing the guidance module to be removed as a unit, reducing the complexity of accessing and maintaining individual components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple guidance mechanisms are merged into a single integrated detachable module. This merging maintains the individual guidance functionality for each fiber bundle path while presenting a unified structure that can be maintained as one component assembly, reducing overall maintenance complexity.

Inventive Principle:
Principle #5Merging (Combining)
