Flexible Thermoplastic Top Cover for Palletized Load Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing top covers for stabilizing the topmost layer of articles in stacks on pallets are inadequate, as they may shift during transport, fail to cover all articles, and are not reusable or easy to transport, especially when exposed to varying temperatures or having different heights.
Innovation Solution
A top cover made of a flexible thermoplastic material with a plate-like shape and flaps that provide frictional and positive locking mechanisms, ensuring stability and adaptability to different article heights, and designed for reusability and easy transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid top cover is used to stabilize the topmost layer of articles, then the stability is improved, but the adaptability to different article heights and temperatures deteriorates
Solution Approach 1:
The top cover is made from a flexible thermoplastic material that can deform and adapt to different article heights and shapes. The flexible main body conforms to the contours of the articles while maintaining stabilizing contact, resolving the contradiction between rigidity for stability and flexibility for adaptability.
Solution Approach 2:
The thermoplastic material's physical parameters (flexibility, temperature response) are optimized to allow the top cover to adapt to varying conditions. The material's inherent flexibility enables it to accommodate different article heights without compromising the stabilizing function.
2Ease of manufacture
If a disposable cardboard top cover is used, then the manufacturing cost is reduced, but the reusability and ease of transport deteriorate
Solution Approach 1:
The material parameters are selected to enable reusability - the thermoplastic material is durable, can be cleaned and reused multiple times. The flexible nature allows it to be compacted for easy transport between uses, maintaining cost-effectiveness while enabling repeated utilization.
3Adaptability or versatility
If a top cover is made from flexible thermoplastic material, then the adaptability to different article heights is improved, but the manufacturing complexity increases
Solution Approach 1:
The top cover utilizes a simple flexible sheet design that conforms to articles without requiring complex mechanical adjustments. The flexibility of the thermoplastic material itself provides the adaptability, eliminating the need for complex mechanisms while maintaining ease of manufacture.
4Ease of operation
If the top cover is made compact for easy transport, then the ease of operation is improved, but the stability during use deteriorates
Solution Approach 1:
The flexible thermoplastic material allows the top cover to be compacted for easy transport while maintaining its stabilizing function during use. The flexibility enables it to conform to articles when deployed, ensuring stability without requiring a permanently expanded structure.
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
The top cover effectively stabilizes the topmost layer of articles by frictional contact and positive locking, maintaining stability during transport and handling, and is reusable and easy to transport due to its flexible design and compact retraction mechanism.
Implementation Method 1
The contact between the main body and the articles provides a frictional connection between the articles and the top cover. Therefore, the articles are prevented from falling off the layer.

AI summary
A top cover (1) for covering a layer of articles, preferably a palletized layer of articles, is provided. The top cover comprises a main body (2) having a substantially plate-like shape, and at least one flap (3) arranged at the main body (2). The flap (3) has a tip end (31) and a mounting portion (32). Further, the tip end (31) is displaceable with respect to the main body (2) between a holding position and a retracted position. In the holding position, the tip end (31) of the flap (3) is spaced apart from the main body (2). Moreover, in the holding position, a main extension direction of the flap (3) is inclined towards a center (c) of the main body (2) by an angle smaller than 90°.
