Solution Overview
Problem
Existing wearable electric field detectors lack convenience and ease of use for electric utility linemen, particularly in detecting high voltage on distribution and transmission voltage power lines.
Innovation Solution
A wearable electric field detector design featuring an inner and outer housing with a cap that can be opened to expose the inner components, including a battery door and acoustic and light chamber, allowing for easy access and providing visual and auditory alerts when high voltage is detected, with a reed switch activated by the outer housing magnet to power the field detection circuitry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the detector uses a compact housing design, then portability is improved, but ease of operation deteriorates due to difficult access to internal components
Solution Approach 1:
The housing is divided into a first housing portion and a second housing portion that can be separated from each other. The first housing portion contains the battery compartment while the second housing portion contains the detection circuitry. This segmentation allows users to access internal components by simply separating the two housing portions, maintaining compact size while improving ease of operation and maintenance.
2Reliability
If the detector includes multiple alert functions (visual and auditory), then detection reliability is improved, but device complexity increases
Solution Approach 1:
The visual alert system (LED indicator) and auditory alert system (acoustic alarm) are merged into a single integrated alert mechanism controlled by the same detection circuitry. Both alert functions share common power supply and control logic, providing redundant detection confirmation while avoiding the complexity of completely separate alert systems. The housing includes an opening that provides access to both the LED and acoustic components.

AI summary
A wearable electric field detector (20) configured to be worn by a wearer in an environment includes inner (22) and outer (24) housings which are movable relative to each other between a closed position and an open position. When in the closed position, a body of the inner housing is concealed within the outer housing, and when in the open position, the body is partially visible (32) to visually indicate that the detector is open. The detector includes field detection circuitry which is configured to detect voltage in an electric field in the environment around the wearer. The circuitry is in communication with at least one of a speaker and a light source which are configured to be activated by the field detection circuitry.
