Snap-Lock Mixer Assembly for High-Pressure Cartridge Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixers for two-component dispensers face issues with secure connections that fail under high shear forces and are unsuitable for uneven material ratios, leading to unintentional detachment and misalignment.
Innovation Solution
A mixer with a form-fitting connection, such as a click or snap lock, and an alignment element ensures secure attachment and alignment with cartridges, allowing for high-pressure resistance and precise mixing ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If simple plug-in connections are used to connect mixer and cartridge, then ease of operation is improved, but connection strength is insufficient to withstand high shear forces
Solution Approach 1:
The connection system is divided into separate functional elements: connection means for mechanical attachment and alignment means for positional accuracy. This segmentation allows each element to be optimized independently - the connection means provides strong mechanical bonding while the alignment means ensures proper positioning without compromising either function.
Solution Approach 2:
The alignment means acts as an intermediary element between the mixer and cartridge, mediating the connection process. It first establishes correct alignment and positioning, then the connection means engages to create the final strong bond. This intermediary step ensures that high-strength connection is achieved only when proper alignment is present.
2Ease of operation
If conventional connections are used, then ease of operation is maintained, but alignment precision for uneven material ratios deteriorates
Solution Approach 1:
By separating alignment functionality from connection functionality, the system maintains ease of operation while achieving precise alignment. The alignment means is specifically designed to ensure correct positioning for uneven material ratios, while the connection means handles the attachment operation independently.
Solution Approach 2:
The alignment means performs preliminary alignment action before the final connection is made. This preliminary positioning ensures that when the connection means engages, the mixer and cartridge are already correctly aligned, enabling precise mixing ratios while keeping the overall attachment process simple.
3Strength
If form-fitting connection is used to withstand high pressures, then connection strength is improved, but device complexity increases
Solution Approach 1:
The connection structure is segmented into distinct functional components: alignment means for positioning and connection means for bonding. This segmentation simplifies the overall design by giving each component a specific, well-defined function rather than creating a single complex integrated structure.
Solution Approach 2:
The alignment means serves multiple functions: it aligns the mixer with the cartridge, ensures correct positioning for uneven material ratios, and guides the connection process. This multi-functionality reduces the need for additional separate components, thereby reducing overall device complexity while maintaining high pressure resistance.

AI summary
A mixer includes a mixer housing, a mixing element, an alignment element and a connection element. The mixing element has a first end and a second end opposite the first end, a longitudinal axis extending therebetween, first and second entry openings arranged at the first end and an outlet opening arranged at the second end, the mixing element further being arranged at least partly within the mixer housing. The alignment element aligns the mixer at a predetermined angle relative to the cartridge. The connection element connects the mixer to a cartridge by a form-fitting connection, and the connection element is a click connection or a snap lock connection.
