Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental material dispensing systems lack reliability and safety, particularly when handling different types of dental materials, and often result in increased costs due to malfunctions and the need for frequent maintenance.
Innovation Solution
A dental dispensing system with a cartridge that includes user-operable contact-based sensors and interfaces for detecting user inputs, allowing for safe and controlled operation of the device, including the use of contactless sensors and mechanical elements to prevent accidental operation without a cartridge, and enabling customized operation modes based on encoded outputs for different materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operating means are integrated into the cartridge, then ease of operation and reliability are improved, but device complexity increases
Solution Approach 1:
The operating means (sensor, interface elements) are segmented from the main dispensing device and integrated into the cartridge. This allows the cartridge to be replaced as a complete unit, improving reliability by ensuring consistent operation across cartridges while managing complexity through modular design.
Solution Approach 2:
The cartridge becomes self-sufficient by incorporating its own operating means and interface. The cartridge can independently provide identification information and control signals, reducing dependency on the main device and improving overall system reliability.
2Object-affected harmful factors
If contactless sensors are used for cartridge detection, then safety is improved, but manufacturing precision requirements increase
Solution Approach 1:
Contactless sensors (optical, capacitive, or inductive) replace mechanical contact-based detection systems. This eliminates the need for precise mechanical alignment and physical contact, improving safety by preventing contamination and cross-contamination between cartridges and the device, while reducing manufacturing precision requirements for mechanical interfaces.
3Adaptability or versatility
If multiple operating modes are supported for different materials, then adaptability is improved, but device complexity increases
Solution Approach 1:
The cartridge interface is designed with universal functionality to support multiple operating modes for different dental materials. The interface can automatically detect the cartridge type and adjust parameters accordingly, providing adaptability across material types while managing complexity through automated recognition and configuration.
Solution Approach 2:
The interface uses feedback from the cartridge (such as identification codes or sensor responses) to automatically determine the appropriate operating mode. This allows the device to adapt to different materials without requiring complex manual configuration, improving versatility while keeping the control system manageable.
