Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-destructive testing (NDT) devices face limitations in maneuverability and flexibility due to the need for multiple cables to transmit signals and power, which occupy valuable space within the tubular housing.
Innovation Solution
The NDT device employs differential signaling to transmit data, allowing for the removal of redundant signal cables, thereby increasing flexibility and maneuverability by reducing cable clutter and optimizing space within the tubular housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cables are used to transmit signals and power, then reliable data transmission and power supply are achieved, but the flexibility and maneuverability of the NDT device deteriorate due to cable clutter occupying valuable space within the tubular housing
Solution Approach 1:
The patent merges the signal transmission and power supply functions into a single integrated cable assembly. The differential signaling protocol allows both data and power to be transmitted through consolidated conductors, eliminating the need for separate cable bundles and reducing internal clutter while maintaining reliable operation
Solution Approach 2:
The single cable assembly serves multiple functions simultaneously: it provides power supply, carries differential signal data, and acts as a shielded conduit for both signal and ground references. This multi-functional design reduces the number of components needed within the tubular housing, improving maneuverability without sacrificing reliability
2Power
If multiple cables are used to transmit signals and power, then sufficient power and data transmission capacity are provided, but the flexibility of the NDT device deteriorates due to increased cable clutter
Solution Approach 1:
The patent combines power transmission and data transmission functions into a single integrated cable assembly. The differential signaling approach allows power and data to share the same conductors, reducing the total number of cables needed and simplifying the overall cable configuration while maintaining adequate power and data capacity
Solution Approach 2:
The cable assembly is designed as a universal component that simultaneously provides power supply, differential signal transmission, and shielding functions. This multi-functional design reduces cable clutter and simplifies the internal configuration of the NDT device, improving flexibility without compromising power or data transmission capabilities

AI summary
Various systems and methods for non-destructive testing (NDT) devices are provided including a tubular housing including a proximal end and a distal end, a head section arranged at the distal end and a bendable articulation section secured to the head section. The NDT also includes a sensor within the head section configured to transmit a data set comprising a first signal to a first output terminal of the sensor and a second signal to a second output terminal of the sensor, wherein the first signal and the second signal are complementary differential signals and a first output signal cable coupled to the first output terminal and extending to a control unit arranged at the proximal end of the tubular housing. The first output signal cable is configured to transmit the first signal to the control unit and the second output terminal is terminated at a ground within the head section.
