Cassette Pivot Axis Parallel to Ejection Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing squeezing devices for containers with masses face challenges such as precise alignment requirements, excessive force distribution on attachment points, and potential cassette detachment during operation, making them difficult to handle and use effectively.
Innovation Solution
A squeezing device design where the receptacle is limited by a head plate and housing wall, with a pivot axis parallel to the squeezing direction, allowing the cassette to pivot easily into position and reducing force exposure on the attachment points, and featuring a detachable cassette with specific angular removal prevention and a blocking mechanism for secure handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cassette is fixed to the ejection device with a pivot axis perpendicular to the ejection direction, then the cassette can be transferred between ejection and loading positions, but the attachment points must be designed to be correspondingly solid to handle the forces occurring when the mass is pressed out
Solution Approach 1:
The pivot axis is reoriented from being perpendicular to the ejection direction to being parallel to the ejection direction (running from the head plate to the housing wall). This dimensional change in the pivot axis orientation allows the cassette to pivot easily into position while the attachment points are no longer subjected to the full ejection forces, simplifying the attachment point design while maintaining ease of operation
2Ease of operation
If the cassette is detachably arranged on the squeezing device, then containers can be easily replaced, but the cassette may accidentally become detached during operation or when the squeezing device is manipulated
Solution Approach 1:
The cassette is designed with a dynamic attachment system that allows controlled pivoting between loaded and unloaded positions while preventing accidental detachment. The pivot axis parallel configuration combined with the bearing design enables the cassette to be securely attached during operation yet easily removed when needed, balancing reliability with ease of operation
Solution Approach 2:
The bearing design provides localized support at specific pivot points, allowing the cassette to pivot smoothly while maintaining secure attachment. The spherical cap-shaped receptacle and cylindrical element create a localized pivot mechanism that prevents detachment during manipulation while enabling easy container replacement
3Force
If the pivot axis runs from the head plate to the housing wall parallel to the squeezing direction, then the cassette can pivot easily into position and forces are reduced on attachment points, but the cassette must be precisely positioned in the receptacle for smooth squeezing
Solution Approach 1:
The pivot axis parallel configuration allows the cassette to self-position within the receptacle through its pivoting motion. The bearing design with spherical cap-shaped receptacle and cylindrical element enables the cassette to automatically align itself during the pivoting process, reducing the need for precise pre-positioning while maintaining smooth squeezing operation
