Solution Overview

Problem

Existing systems for collecting data from rotating components in gas turbine engines face challenges in efficiently installing and testing telemetry modules due to space constraints and the need for clean room assembly, which complicates the assembly and testing process.

Innovation Solution

A telemetry module system comprising a telemetry module and a connector ring, with annular housings and connectivity boards, allows for independent assembly and testing in a clean room environment, facilitating installation in tight spaces and ensuring reliable signal communication through pin receivers and connector pins.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If telemetry modules are assembled and tested in place within the engine, then installation space is utilized, but the assembly and testing process becomes complex and time-consuming

Engineering Contradiction:
Improveassembly and testing processVSAvoidassembly process complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The telemetry module system is divided into two separate components: a connector ring that interfaces with sensor cables and a telemetry module that mounts to the rotating shaft. This segmentation allows each component to be assembled and tested independently in a clean room environment, eliminating the need for complex in-place assembly within the engine and significantly simplifying the manufacturing process.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If telemetry modules are assembled in a clean room environment, then contamination is prevented, but the assembly process becomes more complex

Engineering Contradiction:
Improvecontamination riskVSAvoidassembly process
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The connector ring and telemetry module are pre-assembled and pre-tested in a clean room environment before final installation. This preliminary assembly allows contamination-sensitive components to be protected from contaminants while still enabling simplified final installation on the rotating shaft outside the clean room, resolving the contradiction between contamination prevention and assembly complexity.

Principle #10Preliminary action

3Strength

If the telemetry module is integrated as a single unit, then structural integrity is maintained, but installation in tight spaces becomes difficult

Engineering Contradiction:
Improvestructural integrityVSAvoidinstallation ease
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

By separating the telemetry system into a connector ring and a telemetry module, the system becomes adaptable to tight installation spaces. The connector ring can be positioned independently to accommodate cable routing, while the telemetry module mounts to the rotating shaft, maintaining structural integrity through defined interface connections rather than a monolithic structure.

Inventive Principle:
Principle #1Segmentation
