Universal Power Probe Fixture for Sealed High-Power Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High power systems and devices, such as industrial robots and electric vehicle motor systems, pose challenges for probing due to their sealed nature, making it difficult to physically connect probes for measurement.
Innovation Solution
The Universal Power Probe Fixture (UPPF) and EV Motor Probe Adaptor provide a solution by enabling the connection of probes to high power systems through a universal fixture that supports multiple power transfer circuits and probe configurations, allowing for safe and non-invasive attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If probes are connected to sealed high power systems, then measurement capability is improved, but physical connection difficulty increases
Solution Approach 1:
The patent introduces a power probe fixture as an intermediary device that connects between the sealed high power system and the oscilloscope probe. This fixture includes a connector that attaches to the sealed system without opening it, and a probe connection interface that accepts measurement probes. The intermediary fixture bridges the gap between the inaccessible sealed system and the accessible measurement equipment, enabling non-invasive power measurement.
2Adaptability or versatility
If universal fixture supports multiple power transfer circuits, then adaptability is improved, but device complexity increases
Solution Approach 1:
The power probe fixture is designed with universal functionality to support multiple power transfer circuits and probe configurations through a single device. The fixture incorporates a standardized connector interface that can accommodate various connector types and a modular probe connection system that can be configured for different measurement requirements. This multi-functional design allows one fixture to serve multiple applications across different power systems without requiring separate specialized fixtures for each configuration.

AI summary
A universal power probe fixture (UPPF) that is configured to be installed into a power signal path between a source device and a load device has one or more UPPF base modules, each UPPF base module including an input terminal block, an output terminal block, and a power transfer circuit including a multiple signal lines electrically connected between the input terminal block and the output terminal block, the signal lines structured to convey high power, and each of the signal lines includes a current probe connection point and at least one voltage probe connection point. The UPPF also has a source device connector adapted to electrically connect the source device to the input terminal block, and a load device connector adapted to electrically connect the load device to the output terminal block. A test system using the UPPF, and an application-specific electric vehicle motor probe adapter are also disclosed.
