Solution Overview

Problem

Existing room air purification devices are ineffective in removing aerosols, vapors, smoke, or other atmosphere contaminants directly adjacent to a patient or procedure area, as these contaminants disperse at high velocities beyond the capabilities of these devices.

Innovation Solution

A medical instrument tray and medical evacuation system equipped with a laminar air flow suction device, which includes a first opening connected to a medical vacuum hose and a second opening with a wider width to create a laminar flow, effectively capturing gases and debris from the procedure area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If room air purification devices are used to remove contaminants, then general air circulation is improved, but aerosols and vapors disperse at high velocities that exceed the devices' capabilities

Engineering Contradiction:
Improvecontaminant removal effectivenessVSAvoidaerosol dispersion velocity
Core Design Contradiction:
ReliabilityVSSpeed

Solution Approach 1:

The suction device transitions from general room air circulation to localized procedure area evacuation by positioning a wide second opening directly adjacent to the procedure site, creating a targeted extraction path that operates independently of overall room air flow patterns

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The device employs a non-uniform opening structure with a wide second opening (wider than the first opening) positioned at the procedure area interface, creating localized high-velocity suction exactly where contaminants are generated, while the narrower first opening connects to the vacuum hose for efficient transport

Inventive Principle:
Principle #3Local quality

2Productivity

If the suction device opening is made wider to capture more contaminants, then evacuation efficiency is improved, but the device complexity increases

Engineering Contradiction:
Improvecontaminant evacuation rateVSAvoidsuction device structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The instrument tray and suction device are merged into a single integrated unit, with the tray serving both as a support surface for medical instruments and as the housing structure for the suction device, eliminating the need for separate mounting hardware and reducing overall system complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The instrument tray is designed to serve multiple functions: supporting medical instruments during procedures, housing the suction device, and facilitating contaminant evacuation, thereby reducing the number of separate components needed in the system

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

3Reliability

If the suction device is positioned closer to the procedure area, then contaminant capture is improved, but the instrument tray stability may be compromised

Engineering Contradiction:
Improvecontaminant capture effectivenessVSAvoidinstrument tray stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The suction device is integrated into the instrument tray structure itself rather than being a separate mounted component, ensuring that proximity to the procedure area does not compromise tray stability as the two functions share a common stable base

Inventive Principle:
Principle #5Merging (Combining)

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

The system significantly reduces the spread of airborne bacteria, viruses, or other contaminants by efficiently evacuating gases and debris from the procedure area, enhancing patient and healthcare provider safety.

Implementation Method 1

the second opening width being wider than the first causes a laminar flow of air so that the laminar air flow suction device better captures the gases and debris from the procedure area

Methodology Applied
Scientific EffectLaminar flow: Laminar Flow

Implementation Method 2

A medical instrument tray constructed in accordance with an embodiment of the present invention is operable to support medical instruments and connect to a medical vacuum hose

Methodology Applied
Scientific EffectVacuum suction: Suction
