Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single antenna is used in a wearable electric field detector, then the device structure is simple, but the detection sensitivity and accuracy are lost when not worn in a vertical position
Solution Approach 1:
The single antenna is segmented into two separate antennas mounted perpendicular to each other on the circuit board. This segmentation allows each antenna to detect electric fields in different orientations independently, resolving the contradiction by maintaining detection accuracy across multiple orientations while keeping the overall antenna structure relatively simple.
Solution Approach 2:
The antenna configuration transitions from a single-dimension (vertical) detection to multi-dimension detection by mounting two antennas perpendicular to each other. This dimensional change enables the detector to accurately sense electric fields regardless of the wearer's orientation, solving the accuracy loss problem when not in vertical position.
2Device complexity
If the detector is designed to work only in vertical orientation, then the device structure is simple, but the adaptability to different wearing positions is limited
Solution Approach 1:
The detector is designed with dual perpendicular antennas that enable it to function effectively in multiple orientations (vertical, horizontal, and angular positions). This multi-functionality approach resolves the contradiction by allowing the same device structure to adapt to different wearing positions without requiring orientation-specific configurations.
Solution Approach 2:
The detector incorporates a dynamic orientation detection capability through the perpendicular antenna arrangement, allowing it to automatically adapt to the wearer's position. The system dynamically adjusts its detection sensitivity based on the detected electric field orientation, enabling versatile wearing position adaptability while maintaining a relatively simple overall structure.
3Measurement precision
If two perpendicular antennas are mounted on the circuit board, then the detection accuracy in multiple orientations is maintained, but the device complexity increases
Solution Approach 1:
The two perpendicular antennas are merged into a single integrated detection system on the circuit board, sharing common electronic components and signal processing pathways. This merging approach maintains multi-orientation detection accuracy while minimizing the increase in overall device complexity by consolidating functional elements.

AI summary
A wearable electric field detector is configured to detect an electric field generated by a high-voltage electrical source in an environment, and includes a first antenna, a second antenna, an electrical circuit board operatively coupled to the first antenna and the second antenna, a power source coupled to the circuit board, and a plurality of indicators operatively coupled to the circuit board. The first antenna and second antenna are mounted perpendicular to the circuit board. The detector provides an alert to the user indicative of a strength of a detected electric field. An enclosure houses the first antenna, the second antenna, the circuit board, the power source, and the indicators. The enclosure may be worn by the user in a vertical orientation, a horizontal orientation, and in an orientation disposed between the vertical orientation and the horizontal orientation.
