Bite Fork with Integrated Impression Material Pumping Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bite fork devices require manual application of impression materials, leading to uneven distribution and inadequate quantity, which can result in inaccurate bite registration and misalignment of dental appliances.
Innovation Solution
A bite fork substrate with integrated channels for pumping impression material, allowing for uniform distribution and controlled application through orifices, optionally using a snap fit or clamping mechanism and a manual or motorized pumping mechanism for efficient material flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual application of impression material is used, then the device is simple to operate, but the distribution of impression material is uneven and the quantity is inadequate
Solution Approach 1:
The patent introduces an intermediary pumping mechanism that mediates between the impression material source and the application point. This pump delivers the material through controlled channels, ensuring uniform distribution while maintaining reasonable device complexity through automated material transfer.
Solution Approach 2:
The patent employs pneumatic or hydraulic pumping mechanisms to deliver impression material through internal channels. This allows controlled, uniform distribution of the material to multiple locations simultaneously, resolving the contradiction between distribution precision and device complexity by using fluid dynamics principles.
2Measurement precision
If manual application of impression material is used, then the device structure is simple, but the bite registration accuracy is poor
Solution Approach 1:
The patent segments the material delivery system into multiple channels that can independently deliver impression material to different regions of the bite fork. This segmentation ensures adequate and uniform material quantity at each location, improving bite registration accuracy while keeping each individual channel relatively simple in design.
Solution Approach 2:
The pumping mechanism performs preliminary action by pre-delivering the correct quantity of impression material to all required locations before the actual bite registration process. This ensures that material is available in adequate and uniform quantities when needed, improving measurement precision without requiring complex real-time adjustment mechanisms.
3Quantity of substance
If excessive impression material is applied, then adequate coverage is achieved, but the amount of material required increases
Solution Approach 1:
The patent applies local quality by delivering impression material to specific locations through dedicated channels rather than applying material universally. Each channel provides material only where needed, ensuring adequate coverage at critical points while minimizing overall material consumption by avoiding waste in non-critical areas.
Solution Approach 2:
The pumping mechanism provides continuous controlled delivery of impression material through the channels, ensuring that material is supplied at the right rate and locations throughout the process. This continuous action maintains adequate material presence where needed while preventing excess accumulation, optimizing the balance between material quantity and distribution adequacy.
