Solution Overview

Problem

Existing dispenser devices for bi-component substances in odontology are bulky, expensive, and impractical due to their inability to efficiently handle multiple pairs of components during a single dental treatment session, requiring frequent cartridge changes and resulting in bulkiness and increased costs.

Innovation Solution

A modular dispenser device with a compact design that can house and mix multiple cartridges of bi-component substances, featuring a supporting structure with an inclined base, a dual-chambered receiving seat, a dynamic-static mixer, and a motor-driven ejection system for efficient component mixing and dispensing, allowing for easy cartridge replacement and modular connectivity for reduced bulkiness and improved usability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple identical dispenser devices are used to handle different bi-component substances, then the ability to handle multiple substances is improved, but the bulkiness and space occupation increase significantly

Engineering Contradiction:

Improveability to handle multiple bi-component substancesVSAvoidspace occupation

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines multiple dispenser devices into a single integrated device by providing a supporting structure with multiple receiving seats, each capable of holding different cartridges. This merging approach allows multiple bi-component substances to be handled simultaneously or sequentially without requiring separate dispenser devices, thereby reducing bulkiness while maintaining versatility

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The dispenser device is designed with universal receiving seats that can accommodate different types of cartridges containing various bi-component substances. The mixer and dispensing system are configured to handle multiple substance types through a single device, enabling one device to perform multiple functions that previously required several separate devices

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If frequent cartridge changes are performed to use different bi-component substances, then the versatility is improved, but the time loss and operational complexity increase

Engineering Contradiction:

Improveability to switch between substancesVSAvoidtime for cartridge replacement

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The device allows multiple cartridges containing different bi-component substances to be pre-loaded into the receiving seats before the dental treatment session begins. This preliminary action eliminates the need for frequent cartridge changes during the procedure, as the operator can simply switch between pre-loaded cartridges by rotating the receiving seat or selecting from available positions, thereby reducing time loss and operational complexity

Inventive Principle:

Principle #10Preliminary action

3Volume of moving object

If a single dispenser device houses multiple cartridges and mixing systems, then the compactness is improved, but the device complexity increases

Engineering Contradiction:

Improvedevice compactnessVSAvoidstructural complexity

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

The dispenser device is segmented into modular components including multiple receiving seats, individual mixing chambers, and separate dispensing nozzles for each cartridge position. This segmentation allows each component to be independently designed and manufactured, then assembled into a compact integrated unit. The modular structure reduces overall device complexity while enabling multiple cartridges to be housed efficiently within a compact form factor

Inventive Principle:

Principle #1Segmentation
