Stacking Column Pawl Pitch Minimization via Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stacking columns face challenges in minimizing the pitch between pawls, limiting their ability to accommodate smaller distances between locking mechanisms while maintaining operational connectivity between pawls.
Innovation Solution
The design features pawls with a single support part that includes the axis of rotation, utilizing lever-like drivers with a stop mechanism to transfer the upper pawl to the ready position when the lower pawl is rotated into the working position, allowing for the closest possible pitch and maintaining operational connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the pawl is designed with a support part in front of the axis of rotation and a support or weight part behind the axis of rotation, then the operational connection between individual pawls is maintained, but the pitch between pawls cannot be minimized
Solution Approach 1:
The invention extracts the weight part from the traditional pawl design, leaving only the support part with the axis of rotation at its rearmost end. This removal of the rear support/weight part eliminates the space requirement behind the axis, enabling minimal pitch between adjacent pawls while the lever-like drivers maintain the necessary operative connection.
Solution Approach 2:
The invention introduces lever-like drivers as intermediary elements that facilitate the operative connection between individual pawls. These drivers transfer the upper pawl to the ready position when the lower pawl rotates into the working position, replacing the direct connection that would require more space in traditional designs.
2Length of moving object
If the pitch between pawls is minimized, then space efficiency is improved, but the space for active connection between pawls is reduced
Solution Approach 1:
The invention resolves the space conflict by transitioning the active connection mechanism into a different dimensional arrangement. The lever-like drivers are arranged on a rotation axis and utilize rotational motion rather than linear spacing, allowing the connection mechanism to fit within the minimal pitch between pawls by operating in the rotational dimension rather than requiring additional linear space.
3Ease of manufacture
If the pawl design is simplified to only a support part with axis of rotation, then manufacturing complexity is reduced, but the mechanism for transferring pawls to ready position becomes more complex
Solution Approach 1:
The invention segments the system into distinct functional components: simplified pawls that only provide support and rotation, and separate lever-like drivers that handle the active connection and position transfer. This segmentation allows each component to be optimized independently - the pawls are simple to manufacture while the drivers handle the complexity of coordination.

Function Achieved in This Case
This configuration enables the arrangement of latches with the smallest possible pitch, ensuring effective operational connectivity and efficient use of space, allowing for precise positioning and secure holding of loads.
Implementation Method 1
When turning the pawl from the rest position to the ready position, the upper driver remains in the rest position. At the end of the rotation into the ready position, however, the stop of the lower driver runs onto the control edge of the upper driver, so that when the lower pawl is rotated into the work division, the stop takes the upper driver and thus the upper pawl with it
