Solution Overview
Problem
Existing beverage brewing devices, such as coffeemakers, have complex and precise capsule rejection mechanisms that are difficult to assemble and prone to component fatigue, leading to inefficient and not smooth capsule ejection.
Innovation Solution
A simplified capsule rejection mechanism featuring a movable stopping capsule plate with an elastic mechanism and guiding structures, where the capsule is held by a holding mechanism and released through a combination of gravity and elastic force, ensuring smooth ejection without deformation or fatigue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex capsule rejection mechanism with multiple components is used, then the capsule can be rejected, but the structure becomes complicated and assembly becomes difficult
Solution Approach 1:
The patent combines the capsule rejection function into a single integrated stopping capsule plate that integrates multiple functions: stopping the capsule, guiding its movement, and enabling ejection. This merging of functions into one component resolves the technical contradiction by achieving reliable capsule rejection without the need for multiple separate components, thus reducing structural complexity and assembly difficulty
Solution Approach 2:
The stopping capsule plate serves multiple purposes: it acts as a stopper, a guide, and an ejection mechanism. This multi-functional design allows the system to achieve reliable capsule rejection while minimizing the number of components needed, thereby resolving the contradiction between reliability and device complexity
2Reliability
If a capsule scraping hook with elasticity is used to hook the capsule edge, then the capsule can be rejected, but the hook may deform due to fatigue over time
Solution Approach 1:
The patent extracts the elastic deformation function from the stopping capsule plate and replaces it with a pure mechanical movement system driven by the second frame. The plate moves along a predetermined path without relying on elastic deformation, eliminating fatigue stress and significantly extending component service life while maintaining reliable capsule rejection functionality
Solution Approach 2:
The design uses a rigid, non-deformable stopping capsule plate that performs rejection through controlled mechanical movement rather than elastic deformation. This approach replaces the fatigue-prone elastic hook with a durable component designed for long-term reliable operation without degradation
3Productivity
If the second frame moves backward to eject the capsule, then capsule rejection is achieved, but the capsule may be adsorbed on the first frame causing incomplete ejection
Solution Approach 1:
The stopping capsule plate acts as an intermediary between the second frame and the capsule during ejection. It receives the driving force from the second frame and translates it into controlled movement that reliably detaches the capsule from the first frame, ensuring complete ejection even when adsorption forces are present
Solution Approach 2:
The stopping capsule plate is positioned and configured in advance to intercept the capsule before it can be adsorbed to the first frame during the backward movement of the second frame. This preliminary positioning ensures that the capsule is controlled throughout the ejection process, preventing incomplete ejection and maintaining high productivity and reliability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a more rational and less complex structure for capsule rejection, ensuring smooth operation and prolonged component life by using a movable stopping capsule plate and elastic mechanism to facilitate capsule ejection, primarily relying on gravity and elasticity for capsule drop.
Implementation Method 1
an elastic mechanism, acting on the stopping capsule plate and keeping the stopping capsule plate in a tendency of moving downward
Implementation Method 2
the circular edge of the capsule is stopped by a front end face of the stopping portion and finally drops under the action of gravity

AI summary
A beverage brewing device with easy rejection of a capsule, comprises a housing (1); a first frame (2); a second frame (3); a holding mechanism, for receiving and holding the capsule (4) after the capsule (4) inserted between the first frame (2) and the second frame (3); characterized in that, a stopping capsule plate (5) is positioned inside the housing (1) and capable of being movable upward and downward, having a stopping portion (51) extending backward to the upper and the rear of a rear surface of the first frame (2), and a spacing (X) for receiving the circular edge (41) of the capsule (4), is formed between the stopping portion (51) and the rear surface of the first frame (2); and an elastic mechanism, acting on the stopping capsule plate (5) and keeping the stopping capsule plate (5) in a tendency of moving downward. The brewing device mainly realizes the rejection of the capsule (4) under the action of the stopping capsule plate (5), and has a few components and simple structure; in the process of removing the capsule (4), the stopping capsule plate (5) will move downward to force the circular edge (41) to generate a downward driving force to the capsule (4), i.e., the dropping force of the capsule (4) is generated by its own gravity and also by elasticity of the elastic mechanism, thereby further ensuring that the capsule is rejected smoothly.
