Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation devices face challenges in maintaining a robust closure system that resists axial and radial forces created by centrifugal pressure, leading to premature wear of mechanical components and increased costs.
Innovation Solution
A receptacle holding unit with a fastening arrangement featuring rotatable engagement surfaces and a locking member that allows for secure closure and easy disengagement, preventing axial separation and reducing mechanical stress on components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a robust closure system is used to resist axial and radial forces from centrifugal pressure, then the closure reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The closure system is divided into modular components: a closure member with engagement features, a receptacle with corresponding engagement surfaces, and a locking mechanism. This segmentation allows each component to be optimized independently while maintaining overall reliability under centrifugal forces.
Solution Approach 2:
The closure member and receptacle are designed with pre-configured engagement surfaces and locking features that automatically engage when the closure member is positioned over the receptacle. The locking mechanism is pre-positioned to engage with the engagement surfaces, providing immediate resistance to axial and radial forces without requiring additional adjustment or complex actuation.
2Reliability
If a robust closure system is used to resist axial and radial forces from centrifugal pressure, then the closure reliability is improved, but the manufacturing cost increases
Solution Approach 1:
By dividing the closure system into separate, standardized components (closure member, receptacle, locking mechanism), each part can be manufactured using optimized processes and assembled through straightforward operations, reducing overall manufacturing complexity and cost.
Solution Approach 2:
The engagement surfaces and locking features are designed with standardized geometric parameters that can be efficiently produced through conventional manufacturing methods such as injection molding or precision machining, avoiding the need for complex, costly manufacturing processes while maintaining the ability to resist centrifugal forces.
3Reliability
If the closure system is designed to prevent axial separation, then the reliability under centrifugal pressure is improved, but the ease of operation for insertion and removal decreases
Solution Approach 1:
The locking mechanism is designed to transition dynamically between locked and unlocked states. During normal operation, the locking features engage to prevent axial separation and provide stable closure. During insertion or removal, the locking mechanism can be easily actuated to disengage, allowing the closure member to be quickly positioned or removed without excessive force or complex operations.

AI summary
A receptacle holding unit (1) for a device for preparing a beverage from an ingredient contained in a receptacle (2). A first part (10) and a second part (20) are movable between a closed position for holding said receptacle and an open position for inserting said receptacle and/or for removal therefrom. A fastening arrangement comprises a locking member (30) movable between: - a locking position for preventing relative rotational movement of the first and second engagement surfaces (11, 21) when the parts (10, 20) are in the closed position; and - an unlocking position for allowing relative rotational movement of the of the first and second engagements surfaces (11, 21) and engagement and disengagement thereof.
