Clinical Dispenser and Applicator for Precise Bonding Agent Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dispensers/applicators for clinical use of bonding materials face issues such as evaporation, cumbersome repeated dipping, contamination risk, inaccurate dosing, and waste due to inefficient liquid delivery, particularly when applying small amounts like bonding agents or silane in dental procedures.
Innovation Solution
A clinical dispenser and applicator with a hollowed-out distal shaft and angled neck, featuring a squeezable design that creates a vacuum to suction and dispense precise amounts of liquid directly from a well, minimizing evaporation and splatter, and allowing controlled application without repeated dipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional syringe-type dispensers are used to dispense bonding materials, then the liquid can be dispensed, but the operator has difficulty controlling the dispensing amount resulting in liquid splatter and waste
Solution Approach 1:
The dispenser uses a flexible squeezable bulb reservoir instead of a rigid syringe-type dispenser. The flexible bulb allows the operator to control the dispensing amount by squeezing to create vacuum for suction and then controlling the release to dispense exact drops, eliminating uncontrolled splatter and waste associated with rigid syringes
Solution Approach 2:
The dispenser enables self-service through its squeezable design that automatically creates vacuum to suction bonding material into the reservoir and allows controlled dispensing without requiring additional equipment or complex mechanisms, giving the operator direct control over dispensing precision
2Adaptability or versatility
If repeated dipping of the dispenser/applicator is used to transfer bonding materials, then the liquid can be applied to multiple teeth, but the process is cumbersome and time-consuming
Solution Approach 1:
The dispenser allows preliminary suction of bonding material into the squeezable reservoir before application. The operator can suction multiple drops into the reservoir in advance, then dispense them sequentially by squeezing, eliminating the need for repeated dipping during the application process and significantly reducing time
Solution Approach 2:
The dispenser combines the suction function and dispensing function into a single device. The squeezable bulb serves both to create vacuum for suction and to control dispensing, merging multiple operations into one integrated tool that can handle multi-teeth application without repeated dipping
3Adaptability or versatility
If repeated dipping of the dispenser/applicator is used to transfer bonding materials, then the liquid can be applied to multiple teeth, but the opportunity for contamination by saliva and moisture increases
Solution Approach 1:
The dispenser enables preliminary suction of bonding material into the sealed squeezable reservoir before leaving the well area. By transferring the material to the closed reservoir system, the bonding material is protected from contamination by saliva and moisture during the application process to multiple teeth
Solution Approach 2:
The squeezable reservoir acts as an intermediary between the bonding material well and the application site. The reservoir provides a closed, controlled environment that prevents direct exposure of the bonding material to oral contaminants while still allowing controlled dispensing onto teeth
