Stacking Column Pawl Locking Mechanism for Secure Load Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stacking columns face challenges in securely fixing pawls in their working position, particularly when designed for transportability, leading to potential displacement and damage of stored goods.
Innovation Solution
The stacking column design incorporates a linkage system that allows individual pawls to be locked separately in their working position, utilizing a locking link and coil spring mechanism to ensure secure locking and easy unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If stacking columns are designed with interconnected pawls via linkage, then the structure achieves coordinated movement, but the fixing reliability of individual pawls in working position deteriorates
Solution Approach 1:
The patent divides the pawl system into independent segments, where each pawl can be locked individually in its working position while remaining connected to the linkage system. This segmentation allows each pawl to maintain its own stable position without being forced into unnecessary movement by the coordinated linkage mechanism.
2Productivity
If all pawls are moved into working position during loading, then complete loading capacity is achieved, but handling complexity increases during partial loading scenarios
Solution Approach 1:
The patent implements a dynamic pawl system where each pawl can independently transition between working and non-working positions based on loading requirements. During partial loading, only the necessary pawls are activated, and during full loading, all pawls engage. This dynamic adaptability simplifies handling operations compared to systems that require all pawls to be in working position regardless of load size.
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
This design effectively prevents the displacement of stored goods by ensuring each pawl is securely locked in its working position, allowing for partial loading without unnecessary pawl movement and facilitating easy handling during load removal.
Implementation Method 1
A coil spring is arranged between the spring fixing and an anchor point... the coil spring is arranged between the anchor point and the spring fixation. This arrangement ensures that the locking link is always swung back to the same position when unlocked and locked.

AI summary
The invention relates to a stacking column for storing stored goods one above the other or next to each other at mutual distances on a pawl (5.1-5.6), which is rotatably mounted between two side walls (1.1, 1.2) on an axle pin, wherein the two side walls (1.1, 1.2) form a U-body (3) with a common rear wall (2), wherein the U-body (3) comprises a foot plate (4), wherein the pawl has a linkage bolt (9), wherein the linkage bolt (9) is movable within a curved slot (8) of the side wall (1.1, 1.2) and thus mobilizes the pawl (5.1-5.6), wherein the linkage bolt (9) is extended through one of the side walls (1.1, 1.2), wherein the linkage bolt (9) slides from the ready position into the working position along an bevel (11) of a locking link (14) and thereby brings the locking link (14) from an initial position into a locking position, wherein the locking link (14) is moved between the side wall (1.1, 1.2) and a slider (19), wherein the locking link (14) has an axis of rotation (13) and a spring fixation (12), wherein a helical spring (20) is arranged between the spring fixation (12) and an anchor point (10), wherein the spring fixation (12) is arranged through a recess (15) of the slider (19) away from the locking link (14) through the recess (15) of the slider (19) and the coil spring (20) is arranged between the anchor point (10) and the spring fixation (12).
