Two-Component Mixing Container Liquid-Tight Communication Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-component mixing containers require high processing and assembly precision to align communication passages between the partition wall member and the second-component containing member, making them complex and difficult to manufacture.
Innovation Solution
A two-component mixing container design featuring a columnar portion and a circular through hole that allows for reliable communication between the first and second communication passages without the need for high precision, using a fitting surface formed between the columnar portion and the circular through hole, and a holding structure that simplifies the fixed state of the partition wall member until the second component is injected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional two-component mixing containers use communication passages between partition wall member and second-component containing member, then liquid flow between chambers is enabled, but high processing and assembly precision is required making manufacturing complex
Solution Approach 1:
The communication passage is segmented into two parts: a first communication passage formed in the partition wall member and a second communication passage formed in the second-component containing member. These segmented passages align to form a complete liquid flow path, enabling reliable communication while reducing the precision requirements for each individual component compared to a single integrated passage.
Solution Approach 2:
The partition wall member acts as an intermediary structure that contains the first communication passage and provides the interface between the first-component containing chamber and the second-component containing chamber. This intermediary structure facilitates liquid flow while simplifying the overall assembly requirements.
2Reliability
If conventional designs require high precision alignment of communication passages, then liquid-tight sealing is achieved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
By segmenting the communication passage into two separate formations (first in partition wall member, second in second-component containing member), the design achieves liquid-tight sealing through the interface between these segments without requiring high precision alignment, thereby reducing assembly complexity.
Solution Approach 2:
The design changes the dimensional parameters of the communication passages to accommodate normal manufacturing tolerances and assembly variations, ensuring liquid-tight sealing is achieved without requiring high precision. The passages are designed with dimensions that maintain sealing effectiveness across a range of alignment conditions.
