Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single antenna is used in a traditional wearable electric field detector, then the device can be kept simple, but it loses sensitivity and accuracy when not worn in a vertical position
Solution Approach 1:
The single antenna is segmented into multiple antenna elements (first antenna and second antenna) arranged in specific geometric patterns. This segmentation allows the detector to maintain sensitivity and accuracy across multiple orientations by having multiple sensing directions, resolving the contradiction between measurement precision and adaptability to different wearing positions.
Solution Approach 2:
The patent transitions from a single-dimension (vertical-only) antenna configuration to a multi-dimensional arrangement with antennas positioned in different spatial orientations. This dimensional expansion enables the detector to sense electric fields regardless of the wearer's orientation, simultaneously improving measurement precision and adaptability.
2Reliability
If multiple antennas are added to maintain detection accuracy in multiple orientations, then detection reliability improves, but device complexity increases
Solution Approach 1:
The multiple antenna elements serve universal functions across different orientations and wearing positions. Rather than requiring separate detection systems for each orientation, the same antenna array provides reliable detection whether the device is worn vertically, horizontally, or at any angle, improving reliability without proportionally increasing complexity.
Solution Approach 2:
Multiple antenna elements are merged into a unified detection system with integrated signal processing. The antennas work together as a coordinated array rather than independent components, allowing the system to maintain high detection reliability while managing complexity through unified design and processing.

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.
