Solution Overview

Problem

Current methods for screening conveyances for prohibited materials are time-consuming and pose risks due to the need for direct contact with expensive and cumbersome detection equipment, which can be vulnerable to damage and exposure.

Innovation Solution

A security apparatus that uses a conduit system to direct airflow from a screening zone to an observation room, where inanimate odor detectors can identify target odors without direct contact, incorporating features like porous structures and baffles for protection and control systems to manage responses to detected threats.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If individual searching of each conveyance is performed, then detection accuracy is improved, but time consumption and resource requirements increase significantly

Engineering Contradiction:
Improvedetection accuracyVSAvoidscreening time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent uses pneumatic principles by employing air flow through conduits to transport odor samples from the screening zone to the observation room. This allows remote detection without physical contact, maintaining detection accuracy while reducing screening time and resource requirements.

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The patent introduces an intermediary system consisting of air flow and conduits that mediates between the conveyance and the detection equipment. The odor samples are transported through this intermediary medium, enabling detection without direct contact and significantly reducing the time and resources needed for individual searching.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If detection equipment is placed in direct contact with conveyances, then detection capability is improved, but equipment vulnerability and personnel exposure increase

Engineering Contradiction:
Improvedetection capabilityVSAvoidequipment exposure risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses air flow as an intermediary to transport odor samples from the screening zone where conveyances pass through to the observation room where detection equipment is located. This intermediary system maintains detection capability while eliminating direct contact, thereby protecting equipment from damage and personnel from exposure to potential threats.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent divides the detection system into separate zones: a screening zone for conveyance passage and an observation room for equipment placement. This segmentation physically isolates the detection equipment from potential threats while maintaining detection functionality through the air flow connection.

Inventive Principle:
Principle #1Segmentation

3Object-affected harmful factors

If discrete placement of detection equipment is implemented, then equipment protection is improved, but system complexity increases

Engineering Contradiction:
Improveequipment protectionVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent employs a relatively simple pneumatic system using air flow and conduits to connect the screening zone to the observation room. This approach provides effective equipment protection through discrete placement while maintaining acceptable system complexity, as the pneumatic components are straightforward and well-understood technologies.

Inventive Principle:
Principle #29Pneumatics and hydraulics
