Solution Overview

Problem

Non-contact voltage testers struggle to align with lightbulb sockets, making it difficult to test for live voltage, especially in scenarios with multiple switches or circuit breakers, and there is a need for a solution that securely holds the tester in place during testing.

Innovation Solution

An adapter is designed with a body that fits over a non-contact voltage tester and features that engage with both the tester and a lightbulb socket, allowing secure attachment and alignment for reliable voltage testing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a non-contact voltage tester is used to test lightbulb sockets, then voltage detection capability is improved, but alignment difficulty and operational ease deteriorate

Engineering Contradiction:
Improvevoltage detection capabilityVSAvoidalignment difficulty
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The adapter serves as an intermediary device that couples the non-contact voltage tester to the lightbulb socket. It features a first engagement feature that interfaces with the tester and a second engagement feature that interfaces with the socket, thereby mediating the interaction between the tester and socket to achieve both precise voltage detection and easy alignment

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The adapter provides multiple functions: it enables alignment of the tester with the socket, secures the tester in place during testing, and facilitates easy attachment and detachment. This multi-functionality resolves the contradiction by combining measurement precision with operational ease in a single device

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If a non-contact voltage tester is used to test lightbulb sockets, then voltage detection capability is improved, but stability and reliability deteriorate

Engineering Contradiction:
Improvevoltage detection capabilityVSAvoidstability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The adapter acts as a stable intermediary that firmly couples the tester to the socket, preventing movement or dislodging during the testing process. This stable connection maintains reliable voltage detection throughout the procedure

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The adapter pre-establishes a secure mechanical connection between the tester and socket before voltage detection begins. The engagement features are designed to lock the tester in the correct position in advance, ensuring stability during the entire testing operation

Inventive Principle:
Principle #10Preliminary action
