Movable Capsule Holder for Reliable Brewing Device Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brewing devices face challenges in construction simplicity and operation reliability, particularly in the transport and ejection of capsules within and out of the brewing chamber using a piston-like movement.
Innovation Solution
A brewing device with a force transmission mechanism that converts rotational motion into longitudinal movement, utilizing a 'U'-shaped actuation element and a base support that moves jointly with the injection disposition to ensure reliable capsule support and ejection, featuring a base support that engages with the capsule rim and is retained by sideways projections for efficient capsule handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a piston-like arrangement is used for capsule transport and ejection, then construction simplicity is improved, but operation reliability deteriorates
Solution Approach 1:
The capsule support function is divided into multiple independent retention elements (first retention element upstream, second retention element downstream, and base support with sideways projections) that work together in a segmented manner during the piston-like movement, improving reliability while maintaining construction simplicity
Solution Approach 2:
The base support is designed to move dynamically with the injection disposition during the piston-like movement, with its position changing relative to the capsule throughout the brewing cycle. This dynamic positioning ensures reliable capsule engagement and ejection while maintaining the simplicity of the overall piston mechanism
2Reliability
If multiple retention elements are added to enhance capsule support, then operation reliability is improved, but device complexity increases
Solution Approach 1:
Multiple retention functions are merged into a single integrated base support structure that includes sideways projections and works in conjunction with the injection disposition. This consolidation provides reliable multi-point capsule support while avoiding the complexity of separate, independent retention mechanisms
Solution Approach 2:
The base support serves multiple functions simultaneously: it provides sideways retention through projections, supports the capsule base, and moves with the injection disposition during the piston-like movement. This multi-functionality improves reliability without adding separate dedicated components for each function
