Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical testing devices often lack a reliable and versatile light source, leading to inefficiencies and safety hazards in dark or hard-to-reach areas, with existing solutions suffering from inadequate illumination, shadow issues, and dependence on the device's power source.
Innovation Solution
A lighted probe with an independently powered integrated light source, featuring a hollow main body, light source housing, and probe tip, where the light source is configured to direct beams toward the conductive end, and includes a separate power source, allowing for wireless or wired communication with electrical testing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light source is positioned on or near the electrical testing device, then illumination is provided, but the light source may illuminate unintended areas and cast shadows from the device itself
Solution Approach 1:
The system separates the light source from the main testing device body, placing it on the probe tip instead. This segmentation allows the light to be positioned at the exact location where illumination is needed, eliminating shadows cast by the device body while preventing illumination of unintended areas.
Solution Approach 2:
A light redirecting member (such as a mirror or reflective surface) is introduced as an intermediary between the light source and the target area. This intermediary redirects the light beams to illuminate the work area directly while preventing the light source itself from being visible and casting shadows.
2Device complexity
If the light source is powered by the device power source, then the device structure is simplified, but the light source cannot be used independently from the electrical testing device
Solution Approach 1:
The system provides dual power source options: the light source can be powered by the device power source when connected to an electrical testing device, or by an independent power source (such as a battery) when used standalone. This multi-functionality allows the lighted probe to be versatile and adaptable to different usage scenarios.
3Illumination intensity
If the light source is positioned to illuminate the work area, then visibility is improved, but the device lacks versatility and is limited to connection with specific electrical testing devices
Solution Approach 1:
The lighted probe is designed with universal compatibility features, allowing it to connect to various types of electrical testing devices through standardized interfaces. The light source and probe structure remain the same while accommodating different device connections, thereby improving versatility without compromising illumination performance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides focused illumination, minimizes shadow interference, and allows the light source to be used independently of the testing device, enhancing accuracy and safety by ensuring adequate lighting for precise electrical testing.
Implementation Method 1
The integrated light source is configured to direct light beams toward the conductive end of the probe tip
Data Source
AI summary
A probe for an electrical testing device has an independently powered integrated light source. The probe has a plurality of lights oriented in a cross-like configuration and housed in a recessed surface of the probe. The plurality of lights projects light beams that extend toward the tip of the probe and illuminate the area directly in front of the tip from 360 degrees. The integrated light source is connected to a power source that is housed in the probe but is independent from the power source used for the electrical testing device.
