Tube Hanger With Multi-Frame Attachment For VESDA
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tube hanger systems for very early smoke detection in aircraft manufacturing are not versatile enough, leading to improper installation, damage, and safety hazards due to their inability to be easily removed and reattached to different aircraft components as the manufacturing process progresses, resulting in inefficient installation and potential damage to both the system and the aircraft.
Innovation Solution
A tube hanger system with a tube hook, suspension arm, and a support coupling mechanism featuring multiple attachment mechanisms designed to couple with various frame types at different stages of aircraft manufacturing, allowing for easy installation and repositioning without damaging the system or aircraft components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If zip ties are used to couple the tubing to the aircraft, then the tubing can be mounted, but the installation leads to foreign object debris, inconsistent installation, and potential damage to the VESDA and aircraft components
Solution Approach 1:
The tube hanger is divided into distinct functional segments: a tube hook for receiving the sampling tube, a suspension arm for positioning, and a support coupling mechanism with multiple attachment mechanisms for different frame types. This segmentation allows each component to perform its specific function optimally while enabling consistent and reliable installation across different aircraft configurations.
Solution Approach 2:
The support coupling mechanism incorporates multiple attachment mechanisms designed to couple with various frame types (first frame type, second frame type, third frame type). This multi-functionality allows a single tube hanger design to be universally applied across different aircraft configurations and manufacturing stages, ensuring consistent installation quality without damaging components.
2Ease of operation
If zip ties are used to mount the tubing, then installation is simple, but the tubing cannot be conveniently removed and repositioned as manufacturing progresses, leading to safety hazards and damage
Solution Approach 1:
The tube hanger design incorporates a suspension arm that can be positioned and attached at different locations along the aircraft structure. The multiple attachment mechanisms allow the hanger to be dynamically repositioned as manufacturing progresses and different frame types become accessible, enabling the system to adapt to changing configurations without requiring permanent installation.
Solution Approach 2:
The tube hanger system is designed to be temporarily installed and easily removed as manufacturing stages progress. The attachment mechanisms allow for convenient removal and reinstallation on different frame types, enabling the system to be recovered and repositioned rather than discarded, thus maintaining safety and functionality throughout the manufacturing process.
3Reliability
If tube hangers are configured for specific aircraft and components, then they can be coupled to that specific frame type, but the lack of versatility results in improper installation and inability to adapt to different manufacturing stages
Solution Approach 1:
The support coupling mechanism is designed with multiple attachment mechanisms, each configured to couple with different frame types (first frame type, second frame type, third frame type). This universal design maintains reliable coupling for each specific frame type while enabling the same tube hanger to adapt to various aircraft configurations and manufacturing stages.
Solution Approach 2:
The attachment mechanisms are designed to interface with different frame type parameters (different geometries, materials, and configurations). By accommodating variations in frame type parameters, the tube hanger maintains reliable coupling across diverse aircraft structures without requiring custom-designed hangers for each specific frame type.
