Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for screening pedestrians and vehicles for prohibited materials are time-consuming and pose risks to trained dogs and their handlers due to direct contact requirements, as well as potential fear or harm from individuals.
Innovation Solution
A method and apparatus that collect air samples from pedestrians and vehicles using airflow through a screening station, directing the samples to an enclosure containing a trained dog for odor identification, allowing for efficient and safe detection of prohibited materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual searching is performed on each pedestrian or vehicle, then detection accuracy is improved, but screening time and resource requirements increase significantly
Solution Approach 1:
The patent introduces an intermediary system consisting of odor collection devices and airflow channels that mediate between the target objects (pedestrians/vehicles) and the detection dog. Instead of direct contact, the system collects odor samples through airflow and transports them to the dog for detection, enabling simultaneous screening of multiple targets without compromising detection accuracy.
Solution Approach 2:
The system creates a copy of the odor information from the target objects by collecting air samples that contain odor molecules. This odor copy is then transported to the dog for detection, allowing the dog to screen multiple targets simultaneously without direct exposure to each one, thus maintaining accuracy while increasing throughput.
2Measurement precision
If a dog is brought into direct contact with pedestrians or vehicles for odor detection, then detection capability is enhanced, but safety risks to the dog and handler increase
Solution Approach 1:
The patent employs an intermediary airflow system that separates the dog from direct contact with potential hazards. Airflow channels and odor collection devices act as mediators, transporting odor samples to the dog without requiring the dog to be in direct contact with pedestrians or vehicles, thereby eliminating safety risks while maintaining detection capability.
Solution Approach 2:
The system replaces the mechanical approach of direct physical contact between the dog and targets with an aerodynamic system. Instead of the dog physically interacting with targets, airflow carries odor molecules to the dog's detection area, substituting mechanical contact with fluid-based odor transport to eliminate safety hazards.
3Productivity
If a dog is placed in a large number of vehicles or among pedestrians for screening, then screening coverage is improved, but potential for injury to the dog and handler increases
Solution Approach 1:
The patent introduces intermediary odor collection devices and airflow channels that enable the dog to screen multiple vehicles or pedestrians simultaneously without direct exposure to each one. The airflow system acts as a mediator that distributes odor samples to the dog, maintaining high screening coverage while ensuring safety reliability by preventing direct contact between the dog and potential hazards.
4Measurement precision
If individuals are searched individually for prohibited materials, then detection accuracy is maintained, but the number of searchers and time required increase significantly
Solution Approach 1:
The system creates odor copies from each target object through airflow collection, allowing a single dog to receive and process odor information from multiple pedestrians or vehicles simultaneously. This eliminates the need for multiple searchers while maintaining detection accuracy, as the dog analyzes odor samples that represent each target without requiring physical presence at each location.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and safe screening of multiple pedestrians and vehicles with a high efficiency rating of over 99%, minimizing risk to canine teams and allowing continuous movement while effectively identifying carriers of prohibited substances.
Implementation Method 1
airflow is generated using ambient environment air. The airflow is directed through the screening station and over a pedestrian or vehicle to entrain odors emitted by the pedestrian or vehicle
Data Source
AI summary
An apparatus and method are provided for screening odor emitters for one or more target odors. A screening station is adapted to permit an odor emitter, such as a pedestrian or vehicle, to pass through the screening station. An observation room contains a dog trained to identify at least one target odor. An airflow inducer; directs airflow through the screening station. A porous passage allows airflow from the screening station to the observation room. Air flows through the screening station to entrain odors emitted in the screening station and passes through the porous passage for sensing by the dog.
