Pressed Wood Pallet Stacking Stability and Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressed wood pallets are difficult to separate from a stacked configuration, requiring manual effort and potentially leading to damage or breakage, which increases operational costs and time.
Innovation Solution
The pressed wood pallet design features a containment seat with an abutment surface and a lower face with contact surfaces, allowing for easy separation and pickup using special transfer vehicles, with minimal operator effort and reduced risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If pressed wood pallets are designed with interlocking coupling for stacking, then stacking stability is improved, but separation difficulty increases
Solution Approach 1:
The pallet structure is divided into separable components: the main body and the detachable support feet. This segmentation allows the pallet to maintain stable stacking through the interlocking geometry of the support feet and containment seats, while enabling easy separation by simply removing the support feet from their receptacles without requiring manual force or special tools.
2Ease of operation
If manual separation of stacked pallets is required, then operator effort increases, but equipment cost decreases
Solution Approach 1:
The pallet design incorporates self-service features where the support feet automatically engage with the containment seats during stacking, and can be easily disengaged by lifting the pallet body slightly. This self-service mechanism eliminates the need for manual prying or special separation tools, significantly reducing both operator effort and time required for pallet separation operations.
3Stability of the object's composition
If tight interlocking coupling is used for pallet stacking, then stacking security is improved, but risk of damage increases
Solution Approach 1:
The coupling mechanism uses local quality differentiation where the support feet have a tapered geometry that provides tight interlocking engagement with the containment seats for stacking security, while the engagement area is designed with sufficient clearance and smooth surfaces to prevent stress concentration. This local quality optimization ensures secure stacking without creating high-stress points that could cause pallet damage or breakage during separation.

AI summary
A pallet that includes at least one main body made of a mixture of loose wooden material and adhesive materials, made in a single body piece and provided with a holding base intended to receive and support one or more manufactured articles. The pallet includes one upper face defining at least one containment seat open at the top, bounded by an upper edge and having a bottom wall; and one lower face opposite the upper face; where the containment seat has at least one abutment surface positioned between the upper edge and the bottom wall so as to define a housing seat of an overlying pallet and the lower face includes at least one contact surface adapted to contact the abutment surface of an underlying pallet, where, in a stacking configuration, the lower face remains lifted with respect to the bottom wall of the underlying pallet.
