Pivotable Blocking Element for Compact Squeezing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing squeezing devices for containers with masses have complex drive trains and require significant space for blocking elements, making them cumbersome and difficult to operate.
Innovation Solution
A compact squeezing device design featuring a pivotable blocking element with a transverse pivot axis relative to the planetary gear's rotation axis, allowing for easy actuation and reduced installation space, along with a separate unlocking switch for independent operation of the blocking element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a linearly displaceable blocking element is used, then the blocking function is achieved, but the installation space required is large
Solution Approach 1:
The blocking element is changed from linear displacement to rotational movement about a pivot axis. The pivot axis runs transversely to the gear axis of rotation, allowing the blocking element to engage and disengage from the ring gear recesses through rotation rather than linear travel. This dimensional change significantly reduces the space required for the blocking mechanism while maintaining its locking function.
2Productivity
If a complex drive train is used, then the piston rod can be advanced, but the device complexity increases
Solution Approach 1:
The blocking element is integrated with the actuating switch mechanism. The same pivotable component serves both as the switch actuator and as the ring gear blocker. When the switch is released, it automatically pivots the blocking element into the blocking position. This merging of functions reduces the number of separate components and simplifies the overall drive train complexity.
3Reliability
If an axially displaceable blocking element is used, then the ring gear can be blocked, but the actuation power requirement is high
Solution Approach 1:
The blocking element operates by rotating about a transverse pivot axis rather than moving axially. This rotational motion allows the blocking element to lever into and out of the ring gear recesses with minimal force. The pivot mechanism provides mechanical advantage, enabling easy actuation by the switch without requiring high power, while still achieving reliable blocking of the ring gear.
