Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental equipment lacks a control system for efficiently collecting, cleaning, and discharging wastewater generated during dental implantation, relying heavily on manual methods that increase the risk of healthcare workers' exposure to harmful substances.
Innovation Solution
A workbench control assembly integrating a cleaning assembly, spittoon, saliva suction assembly, and sewage container, with conveying assemblies and a main control module to automate the collection, cleaning, and discharge of wastewater, ensuring efficient and organized handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual methods are used for wastewater handling, then healthcare workers have direct control over the process, but the risk of exposure to harmful substances increases and efficiency decreases
Solution Approach 1:
The system enables self-service operation where the wastewater handling process is automatically controlled by the control assembly. The spittoon, saliva suction assembly, and conveying assemblies operate autonomously to collect, transport, and discharge wastewater without requiring healthcare workers to manually handle sewage, thereby eliminating direct exposure risks while maintaining operational control.
Solution Approach 2:
The patent replaces manual mechanical handling with an automated control system that uses electrical controls, pumps, and automated conveying mechanisms. The control assembly substitutes human-operated mechanical processes with an integrated automated system that manages wastewater collection and discharge through electronic control signals.
2Productivity
If manual wastewater handling is used, then device complexity is low, but productivity and sewage discharge efficiency are poor
Solution Approach 1:
The patent merges multiple wastewater handling functions into a single integrated control assembly. The spittoon, saliva suction assembly, cleaning assembly, and conveying assemblies are combined and coordinated by a unified control system, allowing simultaneous or sequential operation of multiple functions to improve overall sewage discharge efficiency while managing complexity through integration.
Solution Approach 2:
The control assembly is designed with multi-functionality to handle various types of wastewater (spit, saliva, cleaning water) through a single integrated system. The conveying assemblies can transport different liquids through the same pipeline network, and the control system manages multiple operations (collection, cleaning, discharge) using unified control logic.
3Productivity
If automated control system is implemented, then wastewater handling efficiency improves, but device complexity increases
Solution Approach 1:
The automated control system is segmented into distinct functional modules: the spittoon for collection, the saliva suction assembly for active suction, the cleaning assembly for sanitation, and the conveying assemblies for transport. Each module operates semi-independently under coordinated control, allowing the system to achieve high efficiency while managing complexity through modular architecture that enables independent testing and maintenance of each segment.
