Apparatus and method for removing amalgam and waste particles from dental office suction effluent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing amalgam separators in dental offices are inadequate in terms of collection capacity, separation efficiency, and ease of use for removing amalgam and waste particles from suction effluent, as they fail to effectively separate solids from liquids and do not comply with international standards for amalgam retention.
Innovation Solution
An apparatus comprising an upper chamber with a solids collection canister that imparts a circular flow path to dental suction effluent, separates gases, and directs liquids and solids into the canister via a riser, using a flow restrictor to prevent solid particles from exiting, thereby achieving high separation efficiency and increased collection capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional amalgam separators are used, then amalgam separation is achieved, but collection capacity is limited
Solution Approach 1:
The separator is divided into distinct functional zones: an upper chamber for initial separation and a collection canister for accumulation. This segmentation allows each zone to perform its specific function efficiently while increasing overall collection capacity without excessive complexity.
Solution Approach 2:
The collection canister is nested within or integrated with the upper chamber structure. This nesting approach maximizes space utilization and allows the smaller collection component to be housed within the larger separation chamber, increasing capacity while maintaining compact design.
2Manufacturing precision
If conventional amalgam separators are used, then amalgam separation is achieved, but separation efficiency is insufficient
Solution Approach 1:
Different regions of the separator are designed with different properties: the upper chamber provides a large separation volume with specific flow characteristics, while the collection canister provides concentrated collection space. This local differentiation of functional qualities achieves high separation efficiency without requiring the entire device to be overly complex.
Solution Approach 2:
The design transitions from a single-chamber horizontal separation to a two-chamber vertical arrangement. By utilizing the vertical dimension, the apparatus achieves improved separation efficiency through gravity-assisted phase separation while maintaining a compact footprint.
3Ease of operation
If conventional amalgam separators are used, then amalgam separation is achieved, but ease of use is reduced
Solution Approach 1:
The collection canister is designed as a removable component that can be easily extracted from the main separator body. This extraction capability allows users to empty or replace the collection canister without disassembling the entire separator, significantly improving ease of use despite the added structural complexity of the two-chamber design.
4Manufacturing precision
If solid particles are allowed to exit the collection canister, then fluid flow is maintained, but separation efficiency decreases
Solution Approach 1:
A flow restrictor acts as an intermediary component between the collection canister interior and the exit. This mediator allows liquids and gases to pass through while blocking solid particles, thereby maintaining separation efficiency without completely obstructing fluid flow. The flow restrictor mediates between the conflicting requirements of particle retention and fluid throughput.
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 apparatus effectively separates amalgam and waste particles from dental suction effluent, achieving over 99% retention of solids by weight and improving collection capacity, making it more efficient and user-friendly compared to existing solutions.
Implementation Method 1
A gas component of dental office suction effluent changes direction by more than 60° before it exits the upper chamber through an exit port
Implementation Method 2
A riser conveys a liquid and solids component of dental office suction effluent through a drain into the solids collection canister
Implementation Method 3
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
Implementation Method 4
Solid particles settle and accumulate in the bottom of the collection chamber

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.
