Capsule Brewing Device with Offset Piercing Needles for Easy Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beverage brewing devices are complex in structure, costly, and difficult to clean, with internal structures not easily detachable from the machine body.
Innovation Solution
A beverage brewing device with a simple structure, featuring a barrel body and cover body with piercing needles that pierce the capsule along different straight lines, a sealing unit for cleanliness, and a hinged connection for easy removal, allowing the device to separate from the machine body and only require cleaning of the beverage outlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the beverage brewing device uses a conventional structure, then it can achieve reliable brewing function, but the structure becomes complex and costly
Solution Approach 1:
The brewing device is divided into separate functional modules: a detachable brewing unit with piercing needles, a sealing unit, and a beverage outlet. This segmentation allows each component to perform its specific function independently while simplifying the overall structure and reducing complexity.
Solution Approach 2:
The piercing needle assembly serves multiple functions: piercing the beverage capsule, providing a water inlet through its hollow central section, and enabling detachment of the brewing unit. This multi-functionality reduces the number of separate components needed, simplifying the structure while maintaining reliability.
2Stability of the object's composition
If the beverage brewing device uses a conventional structure, then it can maintain brewing stability, but it becomes difficult to clean and maintain
Solution Approach 1:
The brewing unit is designed as a detachable module that can be easily separated from the main device. The sealing unit can be removed to access internal components, making cleaning straightforward while maintaining brewing stability through consistent sealing and piercing mechanisms.
Solution Approach 2:
The sealing unit and piercing needle assembly can be extracted from the brewing device for separate cleaning. This extraction capability allows thorough cleaning of internal surfaces without disassembling the entire device, maintaining brewing stability while improving ease of cleaning.
3Stability of the object's composition
If the beverage brewing device is non-detachably fixed to the machine body, then it ensures stable operation, but it increases device complexity and cost
Solution Approach 1:
The brewing unit transitions from a fixed to a detachable connection with the machine body. This dynamic design allows the unit to be securely attached during operation for stability, yet easily detached for cleaning and maintenance, reducing overall structural complexity and cost.
Solution Approach 2:
The brewing unit with its piercing needles and sealing unit is designed as a nested structure that fits into the machine body when attached. This nesting approach maintains operational stability during use while allowing easy removal, reducing the need for complex permanent mounting structures.

AI summary
Provided are a beverage brewing apparatus and a beverage machine having the beverage brewing apparatus. The beverage brewing apparatus comprises a barrel body for containing a beverage capsule and a cover body fitted with the barrel body. An inner bottom end of the barrel body and the cover body are respectively provided with a piercing needle for piercing the beverage capsule. When the cover body is closed, the piercing needle at the inner bottom end of the barrel body and the piercing needle on the cover body are disposed along different lines and the beverage capsule is pierced. The central part of the piercing needle on the cover body is hollow and forms a water inlet. The piercing needle on the cover body is sealed to the beverage capsule by virtue of a sealing unit. A beverage outlet is provided at a bottom end of the barrel body.
