Stacking Pin Pallet Layout for Secure Modular Container Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pallet systems fail to securely fix individual containers during transport, leading to instability due to displacement within stacking edges and inadequate adaptability to varying container sizes, with components like springs wearing out over time and requiring additional parts for securement.
Innovation Solution
A system comprising a lightweight pallet with an upper deck and feet, featuring stacking pins that engage with containers through first and second receivers, allowing stable fixation in two positions via manual adjustment or tools, ensuring containers are securely fixed without relying on resilient elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If stacking edges are used to fix containers on the pallet, then containers can be held in place, but individual containers can be displaced within the stacking edge causing instability
Solution Approach 1:
The stacking edge is divided into multiple discrete stacking pins arranged in rows and columns. Each stacking pin individually engages with corresponding pins on container bases, providing precise positioning for each container rather than relying on a continuous edge structure. This segmentation allows each container to be fixed at specific points, preventing displacement while maintaining stack stability.
2Stability of the object's composition
If fixedly installed anti-slip tongues are used to secure containers, then containers are prevented from slipping, but the system is not adaptive to different container sizes
Solution Approach 1:
The stacking pins are designed to be movable between a protruding position (for securing containers) and a retracted position (for pallet nesting). This dynamic capability allows the same pallet structure to adapt to different container sizes and stacking requirements. The pins can be selectively activated based on the specific container configuration, providing both stability and versatility.
3Reliability
If springs are used to pretension stacking members upwards, then stacking members protrude from the pallet surface to secure loads, but the springs wear out after frequent use
Solution Approach 1:
The resilient stop elements (springs) are extracted from the pallet structure and relocated to the container bases. This means the containers themselves carry the resilient elements that engage with the stacking pins, rather than the pallet carrying springs that are subject to wear from repeated loading cycles. The pallet structure becomes simpler and more durable, while the containers provide the necessary compliance.
4Reliability
If a plug-in system with multiple individual parts is used to secure containers, then containers can be secured, but additional parts require extra transport when moving empty pallets
Solution Approach 1:
The stacking pins are integrated directly into the pallet structure as permanent features, eliminating the need for separate plug-in securing devices. The pins are arranged in standardized patterns that work with corresponding features on container bases. This integration reduces the number of individual parts and eliminates the need for additional securing components when transporting empty pallets.

AI summary
The invention relates to a system comprising at least one lightweight pallet and multiple similarly designed containers. Each container has four side walls and container base. The system includes stacking pins as separate components. The pallet features an upper deck with a bearing surface, supported by feet and/or runners, and incorporates first stacking pin receivers. Each container base is provided with at least one second stacking pin receiver. These receivers are dimensioned for insertion of a stacking pin, allowing a container to be securely fixed to the pallet. The stacking pin can be stably arranged in two positions: in the first, it engages the first receiver on the container's side while protruding over the bearing surface to engage the second receiver; in the second, it is countersunk in the first receiver, forming a clamping fit with the upper deck or its thread.
