Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing RF test probes require manual pressing of tips and grounds for measurement, limiting operator flexibility and potentially leading to inaccurate or flimsy connections.

Innovation Solution

A RF test probe adapter comprising a cable adapter and housing that securely couples the RF test probe and cable adapter, allowing for interchangeable configurations and hands-free operation using a hinge mechanism and latch for easy assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual pressing of tips and grounds is used for measurement, then connection can be made, but operator flexibility is limited and hand is occupied

Engineering Contradiction:

Improveoperator flexibilityVSAvoidhands-free operation

Core Design Contradiction:

Ease of operationVSExtent of automation

Solution Approach 1:

The adapter is pre-assembled with the test probe and cable connector, performing the connection action before the operator needs to take measurement. The pre-assembled unit is inserted into the test equipment, eliminating the need for the operator to manually press connections during measurement operations.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If sprung hook end test leads are used for physical coupling, then connection can be made, but connection becomes flimsy and inaccurate

Engineering Contradiction:

Improvephysical couplingVSAvoidconnection stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the mechanical sprung hook connection system with a rigid adapter assembly that uses a cable connector and test probe with fixed, stable contact points. The adapter provides a solid mechanical interface that maintains consistent electrical contact, eliminating the flimsy nature of sprung hooks.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If interchangeable test attachments are used for flexibility, then adaptability is improved, but assembly and disassembly complexity increases

Engineering Contradiction:

Improveinterchangeable attachmentsVSAvoidassembly complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the test probe, cable connector, and adapter into a single pre-assembled unit. This integration eliminates the need for separate assembly and disassembly operations when changing test attachments, as the entire assembly is replaced as one unit, thereby reducing operational complexity while maintaining interchangeability.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A radio frequency (RF) test probe adapter comprises a cable adapter operable for use with a RF test probe and a housing. The cable adapter comprises a cable connector configured to physically couple to a connector of a coaxial cable, a first pin operable to electrically couple a center conductor of the coaxial cable to a first lead of the RF test probe, and a second pin operable to electrically couple an outer conductor of the coaxial cable to a second lead of the test probe. The housing is sized and shaped to secure the RF test probe and the cable adapter in a physically coupled configuration.
