Solution Overview

Problem

The existing manufacturing processes for fiber-reinforced material pieces are inefficient due to the need for a conveying process between the lay-up and trimming stages, which requires laborious work and involves attachment replacement, leading to poor work efficiency.

Innovation Solution

An apparatus with a support structure that allows the lay-up and trimming heads to be retracted without removing them, eliminating the need for attachment replacement and enabling both processes to be performed on the same table, using two structural bodies with lower strength requirements and low-power motors, reducing the overall cost and improving efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the lay-up process and trimming process are performed at different places with attachment replacement, then the processes can be specialized, but the work efficiency deteriorates due to laborious conveying and attachment replacement

Engineering Contradiction:
Improveprocess specializationVSAvoidwork efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent combines the lay-up mechanism and trimming mechanism into a single integrated apparatus. The lay-up head and trimming head are both supported on the same support structure, allowing both processes to be performed on the same table without conveying the workpiece between separate locations. This eliminates the need for attachment replacement and manual conveying, thereby improving work efficiency while maintaining process specialization through dedicated heads for each function.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If a single support structure supports both lay-up head and trimming head, then the device complexity is reduced, but the strength requirement increases

Engineering Contradiction:
Improvestructure integrationVSAvoidsupport structure strength
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The support structure is divided into two separate structural bodies: a first structural body supporting the lay-up head and a second structural body supporting the trimming head. Each structural body has its own driving unit, allowing independent operation. This segmentation reduces the strength requirements for each individual structural body compared to a single unified structure, while maintaining the benefits of integration by having both heads on the same support structure.

Inventive Principle:
Principle #1Segmentation

3Power

If high-power motors are used to drive the support structure, then the driving capability is sufficient, but the cost and energy consumption increase

Engineering Contradiction:
Improvedriving capabilityVSAvoidapparatus cost
Core Design Contradiction:
PowerVSEase of manufacture

Solution Approach 1:

The driving system is segmented into a first driving unit for the first structural body and a second driving unit for the second structural body. Each driving unit uses a low-power motor suited for driving its specific structural body, rather than using a single high-power motor. This reduces the overall cost and energy consumption while providing sufficient driving capability for each individual structural body.

Inventive Principle:
Principle #1Segmentation
