Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental nozzle tips are ineffective in applying a precise amount of impression material to teeth, leading to material waste and errors in imprinting tooth patterns, with little research on methods or devices for efficient application.
Innovation Solution
A dental nozzle tip with an expanded type opening at the outlet, a concavely rounded cut surface, and an acute angle configuration, designed to uniformly apply impression materials, reducing waste and ensuring accurate tooth shape imprinting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional nozzle tip is used to apply impression material, then the application process is simple, but the material is not applied evenly and the amount applied is imprecise, leading to material waste and imprinting errors
Solution Approach 1:
The nozzle tip features a specific geometric configuration with a 45-degree angled outlet and internal dimensions (inner diameter 0.8-1.2mm, outer diameter 1.5-2.0mm, length 5-10mm) that create localized controlled flow characteristics. This local geometric quality ensures uniform material distribution and precise application thickness, directly resolving the contradiction between application precision and material waste by optimizing the flow characteristics at the critical discharge point.
2Manufacturing precision
If a conventional nozzle tip is used, then the device structure is simple, but the application accuracy and uniformity are poor
Solution Approach 1:
The nozzle tip employs specific dimensional parameters (inner diameter 0.8-1.2mm, outer diameter 1.5-2.0mm, length 5-10mm, 45-degree outlet angle) that optimize material flow characteristics. By carefully selecting and controlling these geometric parameters, the invention achieves uniform and accurate material application without requiring complex internal structures, mechanisms, or additional components, thus resolving the contradiction between application uniformity and structural complexity.
3Reliability
If more impression material is applied to ensure complete coverage, then coverage is improved, but material waste increases and cost increases
Solution Approach 1:
The nozzle tip's geometric design creates self-regulating flow characteristics where the 45-degree angled outlet and specific diameter dimensions naturally control material discharge rate and distribution pattern. This self-service mechanism ensures complete and uniform coverage of the tooth pattern without requiring operator judgment or adjustment, automatically preventing both under-application (which would compromise reliability) and over-application (which would increase waste), thus resolving the contradiction between completeness and material waste.
