Customizable Dental Syringe Tip with Nested Interlocking Cores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental syringes face challenges in customizing fluid pressure and discharge patterns, and there is a need to reduce fluid leakage between passages, which can lead to contamination and inefficiencies in dental procedures.
Innovation Solution
The design of customizable syringe tips with adjustable passages and retention features allows for varying fluid pressures and patterns, and incorporates interlock mechanisms to prevent fluid leakage, enabling precise control and hygiene during dental procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed syringe tip design is used, then device simplicity is maintained, but adaptability to different discharge pressures and patterns is limited
Solution Approach 1:
The syringe tip is divided into multiple interchangeable components including outer cores with different passage configurations and inner cores with varying aperture arrangements. This segmentation allows dental professionals to select and combine different components to achieve desired discharge patterns and pressures for specific dental procedures.
Solution Approach 2:
The syringe tip system transitions from a fixed design to a dynamic, adjustable configuration through interchangeable components. Users can change the tip configuration during procedures to adapt to different requirements, making the system dynamically adaptable rather than statically fixed.
2Reliability
If simple passage design is used, then manufacturing ease is improved, but fluid leakage between passages increases
Solution Approach 1:
An inner core is nested within the outer core passage structure. The inner core fits inside the outer core, creating a nested configuration that effectively seals and contains fluids within designated passages. This nested design prevents fluid leakage between passages while maintaining structural integrity.
Solution Approach 2:
The inner core acts as an intermediary element between different fluid passages. It serves as a mediator that separates and isolates fluid streams, preventing unwanted mixing or leakage between passages while allowing the passages to function independently.
3Reliability
If disposable syringe tips are used, then contamination risk is reduced, but cost-effectiveness decreases
Solution Approach 1:
The syringe tip is segmented into reusable outer core components and disposable or interchangeable inner core components. This allows the expensive outer structure to be reused while only the inner components that contact patients are replaced, reducing overall costs compared to complete disposable tips while maintaining contamination prevention.
Solution Approach 2:
The outer core components are designed to be universal and reusable across multiple patients and procedures. By making the outer structure multi-functional and durable while allowing replacement of inner components, the system achieves both cost-effectiveness through reuse and reliability through contamination prevention.

AI summary
A dental syringe tip system for attachment to a dental syringe. The dental syringe tip system can include components such as an outer core, an inner core, and a carrier which can be combined in a multitude of combinations to achieve different fluid flow characteristics, such as discharge pressure and discharge pattern, through the dental syringe tip. The outer core and inner core can have passages designed to modify fluid flow characteristics. In addition, the outer core and inner core can have additional connectors for receiving fluids from sources other than a dental syringe. Some or all of the components can be separate to be assembled by a manufacturer or an end-user. Assembly of multiple components can be facilitated by retention features located on the components.
