Edge Protector Packaging for Flat Item Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging methods for fragile flat items, such as framed art and mirrors, are inadequate in providing protection against damage during shipment due to lack of versatility and insufficient shock absorption, often resulting in breakage.
Innovation Solution
A shipping system utilizing edge protectors with u-channel support members that surround and suspend the item within a box, providing a cushioned space to absorb shocks and prevent direct contact with the container, combined with cross-members that push outwards to secure the item in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional packaging boxes are used for fragile flat items, then the packaging is simple and inexpensive, but the items are susceptible to damage from vibration and shock during shipment
Solution Approach 1:
The packaging system is divided into separate functional components: edge protectors with jaw members for corner protection, u-channel support members for lateral support, and cross-members for internal reinforcement. This segmentation allows each component to address specific vulnerability points of fragile flat items independently, improving overall protection without requiring complete redesign of the entire packaging system.
Solution Approach 2:
The packaging components are designed to nest within each other and within the shipping box. The u-channel support members fit into the box corners, edge protectors attach to the u-channels, and cross-members insert through the edge protectors. This nested arrangement maximizes space utilization and provides multi-layer protection while maintaining a compact overall structure.
2Reliability
If edge protectors and u-channel support members are added to provide protection, then shock absorption improves, but the packaging becomes more complex and harder to assemble
Solution Approach 1:
The edge protectors are pre-attached to the u-channel support members during manufacturing, creating a pre-assembled unit that simplifies the final packaging process. The cross-members are designed to insert through the edge protectors in a single motion, and the entire assembly is configured to fit within the shipping box without requiring complex manipulation. This preliminary preparation of components significantly reduces assembly difficulty while maintaining the shock absorption benefits.
3Strength
If a rigid box structure is used for shipping, then structural strength is maintained, but the items lack cushioning and protection during handling
Solution Approach 1:
The packaging system applies different levels of protection to different locations and aspects of the fragile flat item. Corner protection is provided by edge protectors with jaw members that conform to the item's corners. Lateral support is provided by u-channel support members that fit into box corners. Internal reinforcement is provided by cross-members that span the item's surface. This localized quality approach ensures that protection is concentrated where needed while maintaining overall box strength.
Solution Approach 2:
The packaging system combines multiple materials with complementary properties: rigid u-channel support members for structural framework, flexible edge protectors for cushioning and corner protection, and cross-members for internal reinforcement. This composite approach allows the packaging to simultaneously provide structural strength and cushioning protection, addressing both the box strength requirement and the damage prevention requirement.

AI summary
A shipping system comprising: a plurality of edge protectors, each of the edge protectors comprising: a backwall; an upper jaw member in communication with the backwall, the upper jaw member having a top surface; a lower jaw member in communication with the backwall, the lower jaw member having a lower surface, and the lower surface and the top surface are generally flat and parallel to each other; a single slot defined by the upper jaw member and the lower jaw member, and the single slot being generally orthogonal to the backwall, the edge protector having an outer width; at least one u-channel support member, the u-channel support member comprising: a bottom wall; a first sidewall extending generally orthogonally from the bottom wall; a second sidewall extending generally orthogonally from the bottom wall; an interior width between an interior surface of the first sidewall and the interior surface of the second sidewall, and where the interior width is generally equal to the outer width. A method of shipping generally flat items.
