Solution Overview

Problem

Existing technologies fail to accurately locate animate entities, such as humans, by detecting the unique non-uniform three-dimensional electric field spatial gradient pattern, which is essential for line-of-bearing direction indication, especially under obscured or interfering conditions.

Innovation Solution

The use of dielectrokinesis (phoresis) effect, which induces a force and subsequent torque on a beam, combined with an analog matching filter to detect and indicate the direction of the strongest electric field spatial gradient, allowing for the detection of animate entities regardless of obscuring materials or adverse conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If visual amplification technology (lens and digital means) is used, then visibility is improved, but it cannot detect entities obscured by walls, trees, or other materials

Engineering Contradiction:
ImprovevisibilityVSAvoidobscuring material structures
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent uses an intermediary electromagnetic field as a mediator to detect animate entities through obscuring materials. Instead of relying on visible light that cannot penetrate walls and trees, the system employs electromagnetic fields that can pass through these obstacles and interact with the dielectric properties of living tissues, enabling detection of obscured entities.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/optical visual amplification system with an electromagnetic field-based detection system. Instead of using lenses and digital processing to enhance visible light, the system uses electromagnetic fields to detect the unique dielectric response of animate entities, substituting a fundamentally different physical mechanism.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Illumination intensity

If infra-red/heat sensing sensors are used, then night vision capability is improved, but detection is still blocked by solid obstacles like walls

Engineering Contradiction:
Improvenight vision capabilityVSAvoidsolid obstacles
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the detection parameter from thermal radiation (infrared) to dielectric response to electromagnetic fields. While infrared sensing detects heat signatures, this system detects the unique dielectric properties of animate entities by measuring their response to applied electromagnetic fields, allowing penetration through solid obstacles that block both visible light and infrared radiation.

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If radar technology is used, then detection through walls is improved, but it cannot distinguish animate entities from inanimate objects

Engineering Contradiction:
Improvedetection through wallsVSAvoidentity identification accuracy
Core Design Contradiction:
Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The patent applies local quality by detecting the unique dielectric properties specific to animate entities. Instead of using general-purpose radar that detects all objects similarly, the system measures the localized dielectric response of tissues, which has characteristic frequency-dependent behavior unique to living matter, enabling differentiation between animate and inanimate objects.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses dynamic measurement by applying electromagnetic fields at multiple frequencies and measuring the time-varying dielectric response. Animate entities exhibit dynamic polarization and depolarization behavior in response to changing field frequencies, whereas inanimate objects show static or different dynamic characteristics, enabling precise identification.

Inventive Principle:
Principle #15Dynamics

4Difficulty of detecting and measuring

If electrostatic field detection is used, then entity detection is achieved, but the force signal is extremely weak and difficult to detect

Engineering Contradiction:
Improveentity detection capabilityVSAvoidforce signal strength
Core Design Contradiction:
Difficulty of detecting and measuringVSMeasurement precision

Solution Approach 1:

The patent employs mechanical vibration by using a quartz crystal resonator as a highly sensitive force detector. The resonator's natural oscillation is disturbed by the extremely weak electrostatic forces from animate entities, and this disturbance is amplified through resonance, making the otherwise undetectable forces measurable with high precision.

Inventive Principle:
Principle #18Mechanical vibration

Solution Approach 2:

The patent creates a universal detection system that can detect various types of animate entities (humans, animals) using a single electrostatic force measurement approach. The system universally detects the dielectric response of any animate entity by measuring the electrostatic force it exerts on the resonator, regardless of the specific type of entity.

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

AI summary

An analog matching filter includes a first plate, a second plate coupled with the first plate and separated from the first plate via a spacer, and a replicate matching material fixed to an inside surface of the first plate. A conductive plate or sheet is fixed to an inside surface of the second plate, and an electrical circuit connects the first plate to the conductive plate or sheet. The replicate matching material and the conductive plate or sheet generate an opposite polarization pattern carried by the electrical circuit that is based on a polarization pattern of an animate entity according to a spatial gradient of the animate entity local electric field distribution.
