Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Batch processing of composite laminate parts leads to inefficient use of production floor space and challenges in quality control due to the difficulty in detecting part nonconformities in a batch of parts.
Innovation Solution
A continuously moving line system with multiple work zones and mobile platforms, where laminators apply composite material as tools move through the zones, coordinated by a controller to enhance production efficiency and quality control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If batch processing is used in stationary locations, then equipment can be used to produce parts, but production floor space is inefficiently utilized and mandrel utilization is low
Solution Approach 1:
The system transitions from stationary mandrels to mobile platforms that continuously move through the production facility. This dynamic approach allows multiple platforms to be in different stages of production simultaneously, increasing floor space utilization while maintaining high productivity.
Solution Approach 2:
The continuous movement of platforms through the facility enables uninterrupted production. While one platform is being processed, another is being prepared, and a third is being cured, eliminating idle time and maximizing equipment utilization without requiring excessive floor space.
2Reliability
If batch processing is used with stationary mandrels, then parts can be produced, but quality control becomes challenging due to difficulty in detecting part nonconformities
Solution Approach 1:
The system incorporates sensors and monitoring equipment that continuously track platform positions, lamination parameters, and part quality metrics. This real-time feedback enables immediate detection of nonconformities and allows for corrective actions before defects propagate through the batch.
Solution Approach 2:
Manual inspection of finished parts is replaced with automated sensing systems that continuously monitor the lamination process. Optical sensors, force sensors, and other detection devices provide objective, real-time quality data, making nonconformity detection easier and more reliable.
3Productivity
If multiple stationary laminators are used to increase production rates, then more parts can be produced, but device complexity and floor space requirements increase
Solution Approach 1:
Each mobile platform serves multiple functions: it carries the mandrel, supports the part during lamination, provides curing capability, and enables transport between work zones. This multi-functionality allows a single platform to replace what would traditionally require multiple dedicated stationary devices.
Solution Approach 2:
The system adds the dimension of time by implementing continuous movement through the facility. Instead of having multiple laminators operating in parallel at the same location (horizontal expansion), the single laminator processes multiple platforms sequentially as they move through the facility (temporal expansion), achieving increased production without proportionally increasing device complexity.
