Split-Shell Mounting Device for Gas Turbine Wire Harnesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting devices for electrical harnesses in gas turbine engines are often influenced by the configuration of wire breakouts and connectors, making them difficult to arrange and secure effectively, and they lack durability in high-temperature environments.
Innovation Solution
A mounting device comprising two shells with segmented regions and fasteners that restrict movement along the wire bundle, allowing for secure attachment without needing to slide over connectors or breakout segments, and can be easily detached and reattached, using high-temperature resistant materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mounting devices are arranged to slide over connectors or breakout segments, then the mounting device can be installed, but the arrangement is heavily influenced by wire configurations making it difficult to secure effectively
Solution Approach 1:
The mounting device is divided into two separate shells (first shell and second shell) that can be independently positioned and secured to the wire bundle. This segmentation allows each shell to be mounted independently without needing to slide over connectors or breakout segments, thereby reducing the influence of wire configurations on mounting device arrangement while maintaining ease of installation.
2Reliability
If mounting devices are secured to wire bundles, then the harness is protected, but the mounting devices lack durability in high-temperature environments
Solution Approach 1:
The mounting device uses composite material construction with shells made from high-temperature resistant materials such as PEEK (polyether ether ketone) or PTFE (polytetrafluoroethylene). These materials maintain their mechanical properties and structural integrity in high-temperature gas turbine environments, thereby ensuring both harness protection and thermal durability simultaneously.
3Stability of the object's composition
If mounting devices are designed to be securely fastened, then the harness is stable, but the devices are difficult to detach and reattach
Solution Approach 1:
The mounting device incorporates a dynamic fastening system using reversible adhesive mechanisms that allow the shells to be securely attached during normal operation but easily detached when needed. The adhesive strength can be controlled to provide sufficient holding force for stability while allowing controlled removal for repositioning or replacement, thus achieving both stability and ease of repair.
4Ease of operation
If mounting devices are arranged based on wire configurations, then the harness can be organized, but the fastening system complexity increases
Solution Approach 1:
The mounting device is designed as a universal component that can be applied to wire bundles of various configurations and sizes through adjustable shell dimensions and configurable fastening mechanisms. This universality allows the same basic mounting device design to organize different harness arrangements without requiring complex, configuration-specific fastening systems, thereby maintaining simplicity while achieving effective harness organization.

AI summary
A method of assembling a mounting device (220) for an electrical harness of a gas turbine engine is provided. The electrical harness has a wire bundle (204). The method includes providing a first shell (222) and providing a second shell (224). The method further includes coupling the first shell to the second shell with the wire bundle disposed between the first shell and the second shell such that movement of the first shell and the second shell along the wire bundle is restricted.
