Solution Overview

Problem

Current cable systems for imaging in gas turbine engines require power-intensive operations to change zoom states, leading to substantial resource drain due to continuous action needed to adjust the imaging device's position relative to components, which are difficult to access and deteriorate over time.

Innovation Solution

A cable apparatus with an actuator and power source that allows the cable to assume discrete positions, using a mechanism where the cable translates only when activated, drawing minimal power, and returns to rest positions when deactivated, featuring a housing with rotating and translating elements to adjust the imaging device's position efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the handheld device continuously acts on the cable to maintain a different zoom state, then the imaging device position can be adjusted, but power consumption increases substantially

Engineering Contradiction:
Improvecable position adjustmentVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The cable unit operates intermittently rather than continuously - it is activated to translate the cable to a new position and then deactivated to remain stationary. This periodic operation pattern eliminates continuous power consumption while maintaining the ability to adjust the imaging device position when needed.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses the existing cable translation mechanism to achieve position changes without requiring continuous active control. Once the cable is translated to the desired position, it maintains that position through its mechanical structure without needing continuous power input.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If the cable is made adjustable to change length, then the imaging device can be repositioned, but the system complexity increases

Engineering Contradiction:
Improvecable length adjustmentVSAvoidcable system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the active control function from the entire cable system and concentrates it in a single cable unit with an actuator. The rest of the cable system remains passive and simple, reducing overall complexity while maintaining adjustability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The cable unit serves multiple functions - it acts as both the structural cable element and the active actuation mechanism. This multi-functionality reduces the need for separate control systems and simplifies the overall device architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)
