Mixer Adapter Assembly for Multi-Cartridge Adhesive Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive dispensing systems require different mixers for different two-component composition adhesive cartridges, leading to increased costs and the need for multiple mixer types, and there is a lack of easy cleaning solutions to prevent premature curing of adhesive precursors.
Innovation Solution
A mixer adapter with a connector member, rotatable fastening member, and sleeves that allow a single mixer to be compatible with multiple cartridge types, featuring a poka-yoke design for correct orientation and easy cleaning to prevent premature curing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different-type mixers are used for different-type two-component composition adhesive cartridges, then the mixing compatibility is ensured, but the device complexity and cost increase
Solution Approach 1:
The mixer adapter is designed with a universal interface that can connect to multiple types of adhesive cartridges (e.g., F-type, C-type, A-type) while maintaining compatibility with a single mixer type. The adapter includes configurable channels and sealing elements that can be adjusted to match different cartridge configurations, allowing one mixer to serve multiple cartridge types without compromising mixing reliability
Solution Approach 2:
The mixer adapter acts as an intermediary component between the adhesive cartridge and the mixer. It includes a connector member with configurable channels that interfaces with the cartridge port, and a sealing member that ensures proper sealing. This intermediary structure enables compatibility between different cartridge types and a single mixer type, resolving the contradiction between mixing compatibility and device complexity
2Adaptability or versatility
If the mixer adapter is used to enable one mixer to work with multiple cartridge types, then the adaptability is improved, but the cleaning difficulty increases due to adhesive residue
Solution Approach 1:
The mixer adapter is designed as a segmented, disassemblable structure with separate components including a connector member, sealing member, and channel elements. This segmentation allows each component to be easily removed and cleaned separately, addressing the cleaning difficulty that arises from using the adapter with multiple cartridge types. The modular design enables thorough cleaning of adhesive residue from each segment without requiring complex disassembly procedures
3Productivity
If the mixer adapter remains in use for several cartridges, then the operational efficiency is improved, but the adhesive precursors may cure prematurely due to moisture
Solution Approach 1:
The sealing member is designed to be extractable from the mixer adapter body, allowing complete removal of the sealing element that contacts the adhesive precursors. This extraction capability enables users to remove and replace sealing members as needed, preventing premature curing of adhesive precursors that would occur if the sealing member remained in place and exposed to moisture. The sealing member can be taken out for cleaning or replacement without affecting the overall adapter structure
