Solution Overview

Problem

Reusable pallets and crates often accumulate in excess during transportation due to imbalanced logistics, leading to inefficiencies in load securing and storage, as existing stacking solutions do not effectively accommodate mixed stacks or optimize volume usage.

Innovation Solution

Designing load carriers with complementary stacking contours on both pallets and crates, including a circumferential web on pallets and recessed areas on crates, allowing for interlocking and non-slip stacking, and incorporating strapping grooves with support webs to prevent damage during securing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional stacking contours are used on pallets and crates, then single-type stacking is possible, but mixed stacking of pallets and crates is not effective

Engineering Contradiction:
Improvemixed stacking capabilityVSAvoidreturn transport efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies universality by designing standardized stacking contours (first, second, third, and fourth contours) that enable both pallets and crates to stack with each other as well as with themselves. The complementary contour designs allow a pallet to stack on a crate and vice versa, creating a universal stacking system that increases adaptability and enables efficient mixed stacking in return transport operations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If strapping grooves are added to pallets for load securing, then cargo attachment is improved, but the load table structure becomes more complex and vulnerable to damage

Engineering Contradiction:
Improveload securing reliabilityVSAvoidload table structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the load table into a rib structure with multiple strapping grooves distributed across the surface. This segmentation allows the load table to maintain structural integrity while providing multiple attachment points for cargo securing, reducing the risk of damage concentration at single points and distributing mechanical stresses effectively.

Inventive Principle:
Principle #1Segmentation

3Reliability

If strapping grooves are cut into the load table, then cargo attachment is enabled, but the outer ribs become vulnerable to damage during tightening

Engineering Contradiction:
Improvecargo attachment capabilityVSAvoidrib strength during strapping
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent applies beforehand cushioning by positioning support webs between adjacent ribs in the region of strapping grooves before the strapping operation. These support webs act as protective elements that cushion and distribute the tightening forces, preventing direct concentration of stress on the outer ribs and avoiding damage during the cargo securing process.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

4Productivity

If excess pallets and crates accumulate at destinations, then return transport is necessary, but load securing and storage become inefficient

Engineering Contradiction:
Improvereturn transport efficiencyVSAvoidtime for load securing operations
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-configuring both pallets and crates with standardized stacking contours and strapping groove patterns before they are deployed. This preliminary preparation enables rapid load securing and stacking operations during return transport, eliminating the need for time-consuming on-site adjustments and significantly reducing the time required for securing excess pallets and crates for return journeys.

Inventive Principle:
Principle #10Preliminary action

AI summary

An arrangement of a first cargo carrier in the form of a pallet comprising a cargo table and runners, having first contours on the upper side of the cargo table, at least some sections of said contours being designed to be complementary in shape and arrangement with second contours in a contact surface of the runners, and a second cargo carrier in the form of an optionally foldable crate comprising end walls, side walls and a base, having third contours which are formed by free edges of the end walls and side walls and at least some sections of which are complementary in shape and arrangement with fourth contours which are formed from the crate base, wherein at least some sections of the first contours of the pallet are designed to be complementary in shape and arrangement to fourth contours of the crate, and at least some sections of the second contours of the pallet are designed to be complementary in shape and arrangement to the third contours of the crate, such that when setting the crate base on the cargo carrier surface of the pallet as well as when setting pallets on crates, the contours engage with each other in order to secure the load.
