Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing processes for aircraft elements face challenges in detecting and removing auxiliary materials like protective plastic foils or films, which can lead to structural issues, electrical conduction discontinuity, and thermal expansion differences, resulting in costly and resource-intensive repairs due to the intrusion of these materials into the final aircraft configuration.
Innovation Solution
A method involving the application of detection labels, such as magnetic or acousto-magnetic labels, on auxiliary materials that emit warning signals when detected by a label scanner, ensuring their removal before assembly, thereby preventing material intrusion and simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If auxiliary materials are used during manufacturing, then protection of aircraft parts is improved, but risk of material intrusion and structural issues increases
Solution Approach 1:
The patent applies preliminary action by attaching detection labels to auxiliary materials before the manufacturing process begins. This allows the detection system to identify and alert operators about auxiliary materials present during subsequent manufacturing steps, enabling proactive removal before assembly and preventing material intrusion into the final structure.
2Reliability
If auxiliary materials are removed after assembly, then material intrusion is prevented, but repair time and resources increase
Solution Approach 1:
The detection labels enable preliminary identification of auxiliary materials before assembly is complete. Operators receive warnings during the manufacturing process itself, allowing them to remove auxiliary materials at the appropriate time without needing to perform costly and time-consuming post-assembly repairs.
3Difficulty of detecting and measuring
If detection labels are applied to auxiliary materials, then detection capability is improved, but process complexity increases
Solution Approach 1:
The patent uses detection labels as intermediary elements that bridge the auxiliary materials and the detection system. These labels act as mediators that can be easily detected by scanning devices, translating the presence of auxiliary materials into detectable signals without requiring complex direct detection methods.
Solution Approach 2:
The patent replaces complex mechanical or visual inspection methods with automated label detection technology. The detection system uses magnetic or acoustic fields to read labels on auxiliary materials, substituting manual inspection processes with automated electronic detection that is both simpler and more reliable.
