Retractable Rostrum Frame Latching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rostrum systems require careful guidance and alignment of multiple frame units during retraction, increasing the effort required to ensure smooth stacking due to the increasing mass that needs to be aligned, making the process difficult and labor-intensive.
Innovation Solution
The support structure for a rostrum initiates retraction with the second largest frame unit into the largest, using a latching mechanism that prevents the third frame unit from retracting until the second frame unit has completed a significant portion of its retraction, allowing only one frame unit to be aligned at a time, simplifying the process.

Engineering Contradiction Analysis
1Productivity
If all frame units are retracted simultaneously into the smallest frame unit, then the retraction process is faster, but the alignment difficulty and operator effort increase significantly due to the increasing total mass requiring guidance
Solution Approach 1:
The retraction process is segmented into sequential stages, with each stage involving only one frame unit being retracted at a time. The latching mechanism divides the simultaneous multi-frame retraction into discrete sequential operations, reducing the mass that requires alignment guidance at any given moment while maintaining overall retraction efficiency.
2Ease of operation
If frame units are retracted one by one in sequence, then the alignment process is simplified and operator effort is reduced, but the total retraction time increases
Solution Approach 1:
The latching mechanism is designed to automatically prepare and enable the next frame unit for retraction as each frame unit completes its retraction sequence. This preliminary preparation eliminates idle time between sequential operations, allowing the system to maintain continuous motion while keeping alignment complexity low.
3Device complexity
If a latching mechanism allows simultaneous retraction of multiple frame units, then the system structure is simpler, but the guidance and control requirements become more complex and labor-intensive
Solution Approach 1:
The latching mechanism automatically controls the retraction sequence without requiring external intervention or complex guidance systems. Each frame unit's retraction automatically triggers the next in sequence through the latching mechanism's design, making the system self-regulating and eliminating the need for operators to manually coordinate multiple frame units simultaneously.

AI summary
In a rostrum, comprising a rostrum support structure comprising a plurality of frame units; the frame units comprising at least a first frame unit, a second frame unit which is retractable in a retraction direction from an extended position into the first frame unit, and a third frame unit, which is retractable in the retraction direction from an extended position into the second frame unit, a latching mechanism is provided which is configured so that the third frame unit cannot be retracted from the extended position into the second frame unit until the second frame unit has been retracted from the extended position into the first frame unit. A respective deck is engaged with each respective frame unit.
