Capsule Beverage Machine with Gravity-Aligned Vertical Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage extraction machines using capsules face inefficiencies due to non-coinciding seating and extraction directions, difficulty in varying operations, complex capsule handling, and issues with beverage residue flow and discharge.
Innovation Solution
The beverage machine aligns the capsule seating and extraction directions with gravity, incorporates a cap member that presses and perforates capsules vertically, includes a receiving groove for stable capsule positioning, and features a flow path with check valves to prevent backflow and residue accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the capsule is placed horizontally for extraction, then the capsule can be pressed from the side to inject water, but the discharge direction becomes perpendicular to the pressing direction which reduces extraction efficiency
Solution Approach 1:
The patent inverts the traditional horizontal capsule placement to vertical placement. The capsule is positioned upright in the extraction chamber, with the pressing mechanism applying force from the top downward along the same vertical axis. This inversion aligns the pressing direction and beverage discharge direction, eliminating the perpendicular orientation problem and improving extraction efficiency.
2Productivity
If the capsule is placed vertically to improve extraction efficiency, then the pressing and discharge directions align, but the capsule becomes difficult to separate during the return operation of the pressurizing structure
Solution Approach 1:
The patent segments the capsule structure into distinct functional zones: an upper portion that remains engaged with the pressing mechanism during extraction, and a lower portion that is designed to separate easily. The capsule includes a breakable seal or separation line that allows the upper sealed portion to stay in place while the lower portion detaches, facilitating easy removal after extraction.
Solution Approach 2:
The patent introduces an intermediary component or mechanism between the capsule and the pressing structure that facilitates separation. This could be a release mechanism, a separable connector, or a designed friction interface that allows the capsule to be firmly held during extraction but easily released during the return operation, solving the separation difficulty without compromising extraction efficiency.
3Object-affected harmful factors
If a valve is added to the discharge flow path to prevent remaining beverage from flowing to the floor, then beverage spillage is prevented, but beverage remains in the discharge flow path causing it to flow to the beverage cup during the next extraction
Solution Approach 1:
The patent extracts or removes the valve component from the discharge flow path entirely. Instead of using a valve to control beverage flow, the design employs gravity-assisted drainage, capillary action channels, or a self-draining structure that allows remaining beverage to be completely evacuated from the discharge path after each extraction, preventing both floor spillage and residue accumulation in the flow path.

AI summary
A beverage machine using capsules of the present disclosure may be formed so that a seating direction of the capsule and a direction in which the beverage is extracted may be formed to coincide with the direction of gravity, and a direction of pressurizing and perforating the capsule is toward the direction of gravity, thereby improving extraction efficiency.
