Beverage Capsule Injection Chamber with Rotational Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation devices require manual positioning of beverage substrate capsules in a fixed injection chamber, which can be cumbersome and lacks secure locking mechanisms, especially when transitioning between open and closed states.
Innovation Solution
A beverage preparation device with a movable first injection chamber part that allows the capsule to be positioned at a distance from a stationary chamber, featuring a locking mechanism that uses rotational actuating means to convert rotational movement into translational adjustment, ensuring secure closure and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual positioning of capsule in fixed injection chamber is used, then device structure is simple, but ease of operation deteriorates and alignment precision is poor
Solution Approach 1:
The first injection chamber part is made movable relative to the second injection chamber part along an adjustment axis, allowing dynamic adjustment of the chamber volume and capsule positioning. This movable design enables the chamber to adapt to different capsule positions automatically, improving ease of operation while maintaining a relatively simple overall structure.
2Ease of operation
If movable injection chamber part is used to allow distant capsule positioning, then ease of operation improves, but locking reliability deteriorates
Solution Approach 1:
A locking mechanism with actuating means is introduced as an intermediary between the movable first injection chamber part and the stationary second injection chamber part. This locking mechanism ensures reliable connection when the chamber is closed, preventing accidental opening during operation while maintaining the benefits of the movable chamber design for easy capsule positioning.
3Reliability
If complex lever mechanism is used for chamber closure, then locking reliability improves, but device complexity increases
Solution Approach 1:
The complex lever mechanism is extracted and replaced with a simplified locking mechanism that directly engages between the first and second injection chamber parts. This extracted design maintains the essential locking function while removing unnecessary mechanical complexity, achieving reliable closure with a simpler overall mechanism.
4Ease of operation
If actuating means converts rotational movement to translational adjustment, then ease of operation improves, but device complexity increases
Solution Approach 1:
The actuating means utilizes a cam mechanism with curved surfaces that convert rotational movement of the actuator into translational adjustment of the first injection chamber part. This curved surface design provides mechanical advantage and smooth motion conversion, improving ease of operation while keeping the mechanism compact and relatively simple.
