Solution Overview

Problem

Existing amalgam separators for dental office suction effluent have limitations in collection capacity, separation efficiency, and ease of use, necessitating an improved apparatus and method for removing amalgam and waste particles.

Innovation Solution

The apparatus includes an upper chamber with a solids collection canister, where dental suction effluent enters along a lateral flow path and gases change direction by more than 60° before exiting, while liquids and solids are directed into the canister, and a flow restrictor ensures that solids are retained within the canister.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If existing amalgam separators are used, then amalgam separation is achieved, but collection capacity is limited and separation efficiency needs improvement

Engineering Contradiction:
Improvecollection capacityVSAvoidseparation efficiency
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The apparatus is divided into distinct functional segments: an upper chamber for initial separation and a lower chamber for solids collection. This segmentation allows each chamber to be optimized for its specific function, with the upper chamber handling gas-liquid separation and the lower chamber dedicated to solids accumulation, thereby increasing overall collection capacity while maintaining separation efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces a vertical dimension to the separation process by stacking chambers one above the other. Effluent flows downward from the upper chamber through a flow distributor into the lower chamber, utilizing gravitational potential energy to drive the process. This vertical arrangement increases collection capacity without significantly increasing horizontal footprint while improving separation efficiency through multi-stage processing.

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

2Ease of operation

If existing amalgam separators are used, then separation function is provided, but ease of use requires improvement

Engineering Contradiction:
Improveease of useVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The solids collection canister is designed as a removable component that can be easily extracted from the lower chamber without disassembling the entire apparatus. This allows for simple maintenance and emptying operations, significantly improving ease of use. The flow distributor is also designed as a removable component that can be taken out for cleaning, further simplifying maintenance tasks.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The apparatus incorporates self-cleaning features through its design. The flow distributor automatically distributes effluent evenly across the lower chamber, and the removable components can be easily rinsed under running water. This self-service capability reduces the need for complex maintenance procedures and improves ease of operation.

Inventive Principle:
Principle #25Self-service

3Reliability

If gas component changes direction by more than 60°, then separation efficiency is enhanced, but device complexity increases

Engineering Contradiction:
Improveseparation efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The upper chamber is designed with a curved, domed bottom surface that naturally directs gas flow to change direction by more than 60° as it moves toward the exit. This curved geometry enhances separation efficiency by promoting complete phase separation without requiring complex internal baffles or flow control mechanisms. The curvature achieves the desired flow redirection while maintaining relatively simple device structure.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The apparatus utilizes hydraulic principles to manage flow distribution. The flow distributor at the bottom of the upper chamber uses gravity-driven hydraulic flow to evenly distribute effluent across the lower chamber surface. This passive hydraulic design achieves effective flow distribution and gas direction changes without requiring active mechanical components, thereby enhancing separation efficiency while limiting increases in device complexity.

Inventive Principle:
Principle #29Pneumatics and hydraulics

AI summary

An apparatus and method for removing amalgam and waste particles from dental office suction effluent. The apparatus includes an upper chamber and a solids collection canister removably secured thereto. Dental office suction effluent drawn through a dental suction wand enters the upper chamber along a lateral flow path above a substantially cylindrical internal wall portion. A gas component of dental office suction effluent changes direction by more than 60° before it exits the upper chamber through an exit port. A riser conveys a liquid and solids component of dental office suction effluent through a drain into the solids collection canister. A flow restrictor allows liquids and gases to exit the solids collection canister interior volume but prohibits solids from exiting the solids collection canister interior volume.
