Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for monitoring wire corrosion, such as the ASTM D130 test, are inadequate as they provide limited information on chemical kinetics and time dependence, and existing wire support designs only allow for corrosion testing in liquid phases, not vapor phases, making it difficult to assess lubricant compatibility and corrosion performance in real-time.
Innovation Solution
A scaffold and testing device that supports conductive wires in both liquid and vapor phases within a common housing, allowing for real-time measurement of corrosion using electrically conductive test wires and temperature sensors, with a system to measure electrical properties and compute corrosion based on changes in wire diameter or radius.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional ASTM D130 test method is used, then corrosion evaluation can be performed, but detailed information on chemical kinetics and time dependence is not obtained
Solution Approach 1:
The patent replaces traditional visual inspection methods with electrical resistance measurement to detect corrosion. By monitoring changes in electrical resistance of wire samples over time, the system obtains real-time corrosion kinetics data without requiring complex chemical analysis equipment, thus reducing device complexity while gaining detailed corrosion information.
Solution Approach 2:
The system continuously measures electrical resistance of wire samples and feeds this data back to a monitoring system that calculates corrosion rate in real-time. This feedback mechanism enables continuous monitoring of corrosion kinetics, providing detailed time-dependent information while using a relatively simple measurement setup.
2Adaptability or versatility
If wire support design immerses wire in liquid only, then corrosion testing in liquid phase is enabled, but vapor phase corrosion testing is not possible
Solution Approach 1:
The wire support structure is designed to accommodate both liquid immersion and vapor exposure configurations. The same support framework can hold wire samples in different positions - fully immersed in liquid for liquid-phase testing or positioned in the vapor space above the liquid for vapor-phase testing - enabling multi-functionality without requiring separate testing apparatus for each phase.
Solution Approach 2:
The testing system divides the container into distinct liquid phase and vapor phase zones, with wire supports that can position samples in either zone. This segmentation allows independent testing of both phases using the same overall apparatus, achieving versatility while maintaining relatively simple structural design.
3Productivity
If wire is routed through complex peg design, then wire length can be accommodated in container space, but sample preparation time increases
Solution Approach 1:
The wire support structure incorporates self-aligning features where wires naturally follow grooves or channels that guide them to the correct routing path. This self-service design reduces the time and skill required for wire preparation, as the structure itself assists in proper wire placement rather than requiring complex manual routing procedures.

AI summary
A testing device includes a scaffold for supporting conductive wires. The scaffold is placed in housing in which liquid and vapor phases of a fluid are provided, such that a first of the conductive wires extends into the liquid and a second of the conductive wires remains in the vapor throughout a test. The scaffold may include a plurality of lower support members and a plurality of upper wire support members, each of the support members including a plurality of routing supports to wrap a respective one of the test wires around. The device allows measurements to be made contemporaneously for the test wires.
