Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional filtration methods are used, then coffee concentrate can be separated from grounds, but the process is messy and results in spillage
Solution Approach 1:
The filtration system is divided into separate functional components: a first container for coffee grounds, a closure with filter assembly, and a second container for filtered concentrate. This segmentation allows each component to perform its specific function efficiently, containing the filtration process within a closed system to prevent spillage while maintaining operational simplicity.
Solution Approach 2:
The filter assembly acts as an intermediary component between the coffee grounds container and the concentrate collection container. It mediates the separation process by allowing liquid concentrate to pass through while retaining coffee grounds, enabling clean filtration without direct contact between grounds and the collection container, thus preventing spillage.
2Productivity
If a filter is used to separate coffee concentrate from grounds, then filtration efficiency improves, but vacuum formation can interfere with the process
Solution Approach 1:
The air channel acts as an intermediary pathway that allows air to pass through the closure assembly independently of the liquid filtration process. This mediator component equalizes pressure on both sides of the filter, preventing vacuum formation that would otherwise impede efficient and consistent filtration of coffee concentrate from grounds.
3Object-generated harmful factors
If the filtration assembly is designed to prevent spillage, then cleanliness improves, but device complexity increases
Solution Approach 1:
The filter and air channel are integrated into a single closure assembly that attaches to the coffee container. This merging of filtration and air equalization functions into one unified component achieves spillage prevention through a relatively simple structure, avoiding the need for separate complex mechanisms for each function.
Solution Approach 2:
The closure assembly serves multiple functions simultaneously: it seals the container, houses the filter for separation, provides an air channel for pressure equalization, and prevents spillage. This multi-functionality reduces the need for additional separate components, maintaining device simplicity while achieving comprehensive spillage prevention.

AI summary
A cold brew coffee filtration assembly having a closure. The closure includes a first side and a second side. The first side has a first coupling member configured to couple the closure to a first container. The second side has a second coupling member configured to couple the closure to a second container. A filter is between the first and the second coupling members. A support member supports the filter and defines an air channel extending through the support member and across the filter. A tube is configured to be connected to the support member and extend from the first side of the closure to a bottom of the first container when the first container is coupled to the first side of the closure, the tube further defining the air channel.
