Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing aerospace composite material production processes lack comprehensive tracking and quality monitoring, leading to defects due to accumulated errors and irreversibility in the production steps, making it difficult to control product quality and detect issues in real-time.
Innovation Solution
An indexing method and system for tracking the composite material production process, which integrates recorded data from various production stages, including resin, glue film, and prepreg production, using index marks like QR codes to feed back detailed production data, enabling comprehensive monitoring and quality control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive tracking and quality monitoring are implemented in composite material production processes, then product quality control and defect detection are improved, but device complexity and data integration requirements increase
Solution Approach 1:
The patent segments the composite material production process into distinct stages (resin production, glue film production, prepreg production, molding, curing) and implements separate tracking systems for each stage. Index marks are added at each segmentation point to enable independent quality monitoring while maintaining overall process traceability, thus improving quality control without overwhelming system complexity
Solution Approach 2:
The patent introduces index marks (QR codes or RFID tags) as intermediary elements that carry quality data through the production process. These index marks serve as mediators between different production stages, enabling data integration without direct complex communication between all system components, thereby reducing overall system complexity while maintaining comprehensive tracking
2Loss of information
If detailed production data is recorded and integrated across all production stages, then quality issue analysis capability is improved, but information management complexity and storage requirements increase
Solution Approach 1:
The patent implements preliminary action by adding index marks to materials at the earliest possible stages (resin production, glue film production, prepreg production) before they enter the main production flow. This preliminary tagging ensures that all subsequent quality data can be automatically associated with the correct material batches, maintaining complete information while simplifying data management through pre-established tracking links
Solution Approach 2:
The patent uses index marks as information copies that replicate quality data across multiple production stages. Instead of maintaining complex original data records at each stage, the index mark serves as a portable copy containing essential quality information, reducing information management complexity while ensuring data completeness through distributed information storage
3Loss of time
If real-time monitoring and data integration are implemented across multiple production stages, then quality problem identification speed is improved, but measurement and detection requirements increase
Solution Approach 1:
The patent implements feedback mechanisms where quality data from each production stage is immediately captured, integrated, and fed back to the central tracking system. This real-time feedback enables rapid problem identification by alerting operators to quality deviations as they occur, reducing problem identification time while managing detection complexity through automated data collection at each stage
Solution Approach 2:
The patent employs universal index marks (QR codes or RFID tags) that can carry multiple types of quality information across different production stages. This multi-functional index mark system consolidates various detection requirements into a single tracking mechanism, improving problem identification speed while reducing the overall complexity of measurement and detection systems
