Shipping Container for Rolled Goods with Reinforcing Trays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging for rolled goods like trash bags is inadequate for shipping as it fails to withstand the rigors of commercial courier delivery, often resulting in damaged corners due to the lack of support from the stiff but cylindrical goods.
Innovation Solution
A shipping container design featuring reinforcing trays and a flexible outer wrap to securely enclose rolled goods, providing additional support and protection by sandwiching the product enclosure between the trays and maintaining them in place with a heat-activated shrink wrap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional rectangular cardboard packaging is used for rolled goods, then the packaging can be easily manufactured and is cost-effective, but the corners of the packaging become damaged during shipping due to lack of support
Solution Approach 1:
The packaging is divided into multiple functional components: an inner rectangular box for the rolled goods, corner protectors made of rigid material, and an outer shipping container. This segmentation allows each component to perform its specific function - the inner box provides basic containment, corner protectors prevent damage at vulnerable points, and the outer container provides structural support during shipping.
Solution Approach 2:
Corner protectors serve as intermediary elements between the rolled goods and the outer packaging structure. These protectors are positioned at the corners where stress concentrates during shipping, acting as mediators that absorb and distribute impact forces, preventing direct transmission of damage to the packaging corners.
2Reliability
If the packaging is designed with sufficient strength to withstand commercial courier shipping, then the reliability of shipping is improved, but the complexity of the packaging structure increases
Solution Approach 1:
Instead of uniformly strengthening the entire packaging structure, rigid corner protectors are applied only at the specific locations (corners) where damage is most likely to occur during shipping. This localized reinforcement provides the necessary strength and reliability while minimizing the overall complexity and material usage compared to strengthening the entire package uniformly.
Solution Approach 2:
The packaging system combines different materials with complementary properties: the inner box uses corrugated cardboard for basic containment, corner protectors use rigid material (such as plastic or reinforced cardboard) for impact resistance, and the outer container provides structural framework. This composite approach achieves high reliability for shipping while keeping individual components relatively simple.
3Device complexity
If rolled goods are placed directly in the packaging without additional support structures, then the packaging complexity is reduced, but the corners of the packaging are vulnerable to damage
Solution Approach 1:
Corner protectors are pre-installed on the packaging structure before the rolled goods are placed inside. This preliminary action ensures that the protective elements are already in position to prevent damage before the shipping process begins, addressing the vulnerable corners issue without requiring complex assembly steps at the shipping facility.

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 solution effectively reinforces the packaging, preventing corner damage and ensuring reliable shipping of rolled goods by distributing the weight and stress more evenly, thus enhancing the structural integrity of the container.

AI summary
The present invention relates to a shipping container for rolled goods, particularly relatively heavy and rigid rolled products such as high count rolls of trash bags. In at least one embodiment, the shipping container may be used for shipping a product enclosure containing a pair of rolled trash bags. The shipping container can include a pair of opposing side reinforcing trays to prevent damage to the shipping container when in transit. The invention can conserve the amount of materials used and reduce the shipping weight of the container. The shipping container can further include a flexible overwrap to maintain the reinforcement trays on the opposing side ends of the product enclosure and to provide for additional reinforcement to the shipping container.
