Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tooth processing apparatuses produce significant amounts of dust or powder, contaminating the work environment, posing health risks to workers and causing environmental contamination, and increasing the risk of bacterial infections.
Innovation Solution
An apparatus incorporating a disinfection/sterilization module with a disinfection water producer, air purifier, and UV lamp to suppress dust production, filter out contaminants, and reduce infection risks by spraying disinfection water and emitting UV light during the processing of artificial teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mechanical processing is performed on artificial teeth using CNC machines, then processing precision and manufacturing capability are improved, but dust and powder are remarkably produced causing environmental contamination and health risks
Solution Approach 1:
The patent converts the harmful dust generated during mechanical processing into a manageable byproduct by introducing a water spray system that captures and removes powder particles. The dust generation is inevitable due to mechanical processing requirements, but the water spray transforms this harmful effect into a controllable process where dust is suspended and evacuated, thus converting the harm into a manageable situation.
Solution Approach 2:
The patent introduces water spray as an intermediary substance between the mechanical processing tool and the artificial tooth material. This water medium serves as a mediator that suppresses dust generation during machining while allowing the mechanical processing to continue. The water acts as a bridge that enables the processing to proceed without directly exposing the environment to harmful dust particles.
2Productivity
If mechanical processing is performed on artificial teeth, then manufacturing capability is improved, but bacterial infection risk increases due to worker contact
Solution Approach 1:
The patent implements a self-service disinfection system where the artificial tooth product itself undergoes UV irradiation and water spray treatment during or after processing. This eliminates the need for separate manual disinfection procedures by workers, allowing the product to be automatically disinfected as part of the manufacturing process, thus maintaining productivity while reducing infection risk.
Solution Approach 2:
The patent replaces manual handling and mechanical contact-based disinfection methods with automated UV irradiation and water spray systems. Instead of relying on workers to manually handle and disinfect products, the system uses electromagnetic radiation (UV) and fluid dynamics (water spray) to achieve disinfection, thereby eliminating direct human contact and associated infection risks.
3Object-generated harmful factors
If water spray is used to suppress dust during processing, then environmental contamination is reduced, but additional disinfection infrastructure is required
Solution Approach 1:
The patent merges the dust suppression function and the disinfection function into a single integrated water spray system. The same water spray nozzles that capture and suppress dust during mechanical processing also serve as a delivery mechanism for disinfectant solutions. This consolidation eliminates the need for separate dust suppression and disinfection infrastructure, reducing overall system complexity while achieving both objectives.
Solution Approach 2:
The water spray system is designed with multi-functionality, serving both as a dust suppression medium and as a vehicle for delivering disinfectant solutions. The spray nozzles, water delivery pipes, and control mechanisms are universally utilized for both dust capture during machining and subsequent disinfection of the artificial tooth product, thereby reducing the need for additional dedicated infrastructure.

AI summary
An apparatus for processing an artificial tooth with a disinfection and sterilization function includes: a work bed unit in which a tooth mother material selected from a titanium material or a zirconia material is installed and fixed, and in which a wet-type die that processes a titanium material and a dry-type die that processes a zirconia material are separately disposed; a processing tool unit that has a driving spindle to which a processing tool is coupled at an end thereof and that processes the tooth mother material while moving close to or away from the tooth mother material; and a disinfection/sterilization module that is coupled in a detachable type in the work bed unit and can simultaneously reduce powder and perform disinfection.
