Adjustable Retention Device for Palletized Goods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for securing palletized and cart-loaded goods during transportation, such as shrink-wrap film, are time-consuming, labor-intensive, and environmentally unfriendly, as they require disposal after a single use and can lead to goods shifting or falling, resulting in damage.
Innovation Solution
A reusable transportation container retention device comprising a main panel, extension panel, side straps, restraints, and strap grabbers, which can be adjusted to accommodate varying heights and securely fastened to pallets or carts using hook and loop fasteners, allowing for easy loading and unloading without removing the retention device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shrink-wrap film is used to secure palletized loads, then goods are held in position during transportation, but the process is time-consuming and labor-intensive
Solution Approach 1:
The retention device is divided into multiple functional segments: a main panel for securing goods, an extension panel for additional coverage, side straps for lateral restraint, and restraint elements for attachment. This segmentation allows each component to perform its specific function efficiently, reducing the overall time and effort required compared to continuous shrink-wrapping.
Solution Approach 2:
The extension panel is designed to be movable relative to the main panel, allowing the device to adapt to different load heights and configurations. This dynamic adjustment capability eliminates the need for custom-sized wraps for each load, significantly reducing preparation time while maintaining reliable goods retention.
2Reliability
If shrink-wrap film is used to secure palletized loads, then goods are held in position during transportation, but removal is labor-intensive and the film must be disposed of
Solution Approach 1:
The retention device is designed as a reusable system where components can be easily detached, recovered, and reused for subsequent loads. The side straps and restraints can be removed and reattached to new pallets, eliminating the need for disposal after single use and reducing material waste significantly.
Solution Approach 2:
The device incorporates easy-release mechanisms such as tab-based attachment systems and movable panels that allow workers to quickly remove and reset the retention device without specialized tools or complex procedures, making the recovery process efficient and encouraging reuse.
3Adaptability or versatility
If a reusable retention device with movable extension panel is used, then adaptation to different load heights is achieved, but device complexity increases
Solution Approach 1:
The device is segmented into a main panel and a separate extension panel connected by a hinge or pivot point. This segmentation allows the extension panel to be independently positioned at different angles and heights, providing adaptability to various load configurations while keeping each individual component relatively simple in design.
Solution Approach 2:
The movable extension panel serves multiple functions: it can be extended to increase coverage height, folded back to reduce profile for storage, and positioned at various angles to accommodate different load shapes. This multi-functionality justifies the added complexity by eliminating the need for multiple different device types.
4Reliability
If side straps and restraints are added to the retention device, then securing capability is improved, but device complexity increases
Solution Approach 1:
Multiple securing functions are merged into integrated components. The side straps are attached directly to the main panel at strategic locations, combining the functions of lateral restraint and structural support. The restraints serve dual purposes of attachment to the transportation container and tension application, reducing the need for separate fastening mechanisms.
Solution Approach 2:
The side straps and restraints are pre-positioned and pre-tensioned during device assembly, so that when the device is applied to a load, the securing action is already partially accomplished. This preliminary preparation reduces the complexity of the installation process and ensures consistent securing capability across different uses.

AI summary
A transportation container retention device includes a main panel and an extension panel. The extension panel includes a bottom edge connected to a top edge of the main panel and is configured such that the extension panel can be moved from a first position in which the extension panel overlays the main panel to a second position in which the extension panel is contiguous to the main panel. In this configuration, the transportation retention device is operable to retain various heights of articles located on transportation containers.
