Capsule Carrier Pivot Mechanism for Ergonomic Beverage Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage-preparing machines face limitations in capsule movement control, requiring over-dimensioned bearings, limited angular adjustment for user convenience, and complex ergonomic handling due to oblique interactions between rollers and guides, leading to inefficient capsule loading and operation.
Innovation Solution
A beverage-preparing machine with a rotatable arm and revolving roller system, where the roller engages with the capsule-carrying assembly's guide only during tilting and intermediate positions, disengaging for direct coupling with the dispensing head, allowing for increased angular adjustment and ergonomic handle operation, reducing friction and stress on bearings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the revolving roller is engaged with the rolling guide with predetermined clearance to enable tilting and translation movement, then the capsule-carrying assembly can be positioned correctly, but the bearing associated with the revolving roller must be over-dimensioned to handle the increased forces during pressing
Solution Approach 1:
The patent divides the movement sequence into distinct phases: tilting phase (roller engaged with guide) and pressing phase (roller disengaged from guide). This segmentation allows the bearing to be sized for the lighter tilting forces only, rather than the combined forces including pressing
Solution Approach 2:
The revolving roller dynamically transitions between two states: engaged with the rolling guide during tilting and translation, and disengaged during pressing. This dynamic behavior allows the system to use the roller-guide mechanism only when needed for positioning, while avoiding it during high-force pressing operations
2Adaptability or versatility
If the capsule-carrying assembly is arranged substantially vertically in the loading position, then the mechanism can be simplified, but the user convenience is reduced as it would be more convenient if the seat for housing the capsule were directed angularly towards the user
Solution Approach 1:
The patent introduces an additional rotational degree of freedom about a vertical axis, allowing the capsule-carrying assembly to pivot between vertical and angular positions. This extra dimensional movement enables user-friendly angular loading without fundamentally complicating the primary tilting and pressing mechanism
3Ease of operation
If the handle for operating the actuator member is positioned for front gripping, then the structure can be simplified, but the ergonomics are not optimal for user operation
Solution Approach 1:
Instead of positioning the handle at the front for simple gripping, the patent inverts the approach by positioning the handle on the side for ergonomic operation. This requires the actuator mechanism to transmit rotational motion from a side position to the revolving roller, adding structural elements but significantly improving user comfort
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 enables easier capsule loading, reduced friction, and improved ergonomics, allowing for reliable and efficient capsule alignment with the dispensing head, enhancing user convenience and operational simplicity while reducing bearing stress.
Implementation Method 1
the revolving roller of the arm can disengage from the corresponding guide and the arm is then coupled directly with the capsule-carrying assembly so that the latter can be urged towards and pressed against the dispensing head

AI summary
A machine having a support structure with a hot-water dispensing head, a capsule-carrying assembly which is mounted so as to be movable in a first plane in the support structure. The machine further including a guide means suitable for allowing the capsule-carrying assembly to move between a working position in which the assembly is coupled with the dispensing head and an intermediate position in which the assembly can pivot about a first axis perpendicular to the first plane, towards an angular loading position in which it can receive a capsule. The machine also having an actuating device which includes an actuator member which is rotatable about a second fixed axis and can bring about the movement thereof between the working position and the loading position.
