Current methods for detecting ectoparasites like bed bugs are inefficient, often requiring time-consuming visual inspections, unreliable canine detection, or costly monitors that may miss low-density infestations and involve handling dead bugs, with existing antibody-based systems limited by cross-reactivity and specificity issues.

Innovation Solution

A polyclonal antibody detection kit generated from whole ectoparasite immunogens, including diverse components of different life stages and genders, which specifically binds to ectoparasite antigens, allowing for rapid, sensitive, and discreet detection using a sample contact method and immunization protocols to produce robust antibodies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If visual detection methods are used to inspect for bed bugs, then detection can be performed without specialized equipment, but the process is time-consuming and often fails to detect low-density infestations due to cryptic harborages

Engineering Contradiction:
Improvedetection reliabilityVSAvoidinspection time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces manual visual inspection with an automated optical detection system that uses image capture and processing to identify bed bugs. The system captures images of potential harborages and automatically analyzes them to detect bed bugs, eliminating the need for time-consuming manual inspection while improving detection reliability through consistent, objective image analysis.

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

Solution Approach 2:

The system creates visual copies (images) of the inspection areas and analyzes these copies to detect bed bugs. By working with image copies rather than requiring direct visual inspection of every hidden corner, the system can thoroughly examine areas that would be difficult or time-consuming to inspect manually, thereby improving detection reliability without proportionally increasing inspection time.

Inventive Principle:
Principle #26Copying

2Productivity

If canine detection is used to identify bed bugs, then detection can be performed quickly, but the method produces high false positive rates and requires extensive training

Engineering Contradiction:
Improvedetection speedVSAvoiddetection accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent replaces canine detection with an automated optical system that captures and analyzes images to identify bed bugs. This substitution maintains the speed advantage of canine detection while eliminating false positives through objective image analysis, removing the subjectivity and training variability inherent in canine detection methods.

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

Solution Approach 2:

The system incorporates feedback mechanisms where image analysis results are continuously refined based on detected patterns and known bed bug characteristics. The system learns from positive and negative identification cases, improving its accuracy over time while maintaining rapid detection capabilities, thereby resolving the trade-off between speed and precision.

Inventive Principle:
Principle #23Feedback

3Reliability

If active or passive monitors are deployed to trap bed bugs, then detection sensitivity can be improved, but the devices have large footprint, high cost, and require handling of dead bugs

Engineering Contradiction:
Improvedetection sensitivityVSAvoidmonitor footprint
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces physical trapping monitors with an optical detection system that uses image capture and analysis to detect bed bugs. This substitution eliminates the need for large physical traps and the associated handling of dead bugs, while maintaining detection sensitivity through sophisticated image recognition algorithms that can identify bed bugs at low densities.

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

Solution Approach 2:

The system utilizes color and visual characteristics of bed bugs in captured images to identify and distinguish them from other objects. By analyzing color patterns, size, and morphological features in the images, the system achieves high detection sensitivity without requiring large physical monitors or handling of specimens.

Inventive Principle:
Principle #32Color changes

4Measurement precision

If existing antibody-based detection systems are used, then detection specificity can be improved, but cross-reactivity with other species remains a problem

Engineering Contradiction:
Improvedetection specificityVSAvoidfalse positive rate
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent replaces antibody-based detection with an optical image recognition system that identifies bed bugs based on their visual and morphological characteristics. This substitution eliminates cross-reactivity issues inherent in antibody systems by using multiple visual features for identification, thereby improving both specificity and reducing false positives through pattern recognition rather than single-antigen dependence.

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