Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extraction systems for dental ceramic workstations provide insufficient occupational safety, limited visibility, and hinder product quality due to inadequate shielding and lighting solutions, often leading to malfunctions.
Innovation Solution
A suction device with a main body, extraction tunnel, and discharge opening, coupled with a light arrangement that illuminates the processing area through a frame with centrally positioned light elements, and a transparent protective cover, along with an electrical circuit for activation, ensuring improved visibility and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional protective shields are used to protect the operator, then occupational safety is improved, but the field of vision is restricted and the work area is darkened
Solution Approach 1:
The patent combines the protective shield function with the lighting function by integrating light sources directly into the extraction device housing. This merging eliminates the need for separate protective shields while providing both protection and illumination, thereby resolving the contradiction between safety and visibility.
Solution Approach 2:
The extraction device itself acts as an intermediary that serves dual purposes: it provides particle extraction for safety and incorporates lighting elements to illuminate the work area. This intermediary approach allows the same structure to fulfill both protective and illuminating functions simultaneously.
2Reliability
If the extraction device is positioned to act as a shield for the operator, then occupational safety is improved, but the field of vision is restricted
Solution Approach 1:
The protective function and lighting function are merged into a single integrated device. The light sources are positioned within the extraction device housing to illuminate the work area while the device itself provides protection, eliminating the need for separate protective shields that would block vision.
Solution Approach 2:
The lighting is localized to specific areas within the work zone, with light sources positioned to illuminate only the necessary processing areas. This local illumination approach provides adequate visibility without requiring large protective structures that would restrict the operator's overall field of vision.
3Reliability
If multiple components for extraction and shielding are used, then occupational safety is improved, but the system complexity increases leading to malfunctions
Solution Approach 1:
The patent integrates multiple functions (extraction, shielding, and lighting) into a single unified device structure. By combining these functions rather than using separate components, the system complexity is reduced while maintaining comprehensive safety and functionality.
Solution Approach 2:
The extraction device is designed as a multi-functional unit that simultaneously provides particle extraction, operator protection, and work area illumination. This universal approach eliminates the need for multiple separate components, thereby reducing system complexity and the potential for malfunctions while maintaining occupational safety.
