Reinforced Container Lid Structure for Crush and Warp Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers lack sufficient reinforcement features, particularly at their ends, which can lead to deformation or damage during handling and storage, especially when holding heavy or tightly packed articles.
Innovation Solution
A container design featuring a reinforcement member integrated into the lid and bottom recesses, formed from pulp fiber materials, providing structural support and resistance to crushing and warping, along with a modular configuration allowing reinforcement at one or both ends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforcement members are added to the container ends, then the strength and resistance to crushing/warping improve, but the device complexity increases
Solution Approach 1:
The reinforcement member is received within a recess formed in the lid, creating a nested structure where the reinforcement element is housed inside the container body. This nesting approach provides structural reinforcement while minimizing the overall complexity by integrating the reinforcement within existing container features rather than adding external components.
Solution Approach 2:
The container is divided into separate components including the body, lid, and reinforcement member that can be manufactured independently and then assembled. This segmentation allows each component to be optimized for its specific function while simplifying the overall manufacturing process and reducing complexity through modular assembly.
2Reliability
If reinforcement members are integrated into the lid and bottom recesses, then the reliability under heavy loads improves, but the manufacturing precision requirements increase
Solution Approach 1:
The recess is formed in the lid during the lid manufacturing process before assembly with the reinforcement member. This preliminary formation of the recess ensures proper fit and positioning of the reinforcement member while allowing for standard manufacturing tolerances rather than requiring high-precision operations during final assembly.
Solution Approach 2:
The reinforcement member is formed from a material that can be molded or shaped to fit the recess, allowing for adjustment of material properties and dimensions to accommodate standard manufacturing tolerances. This parameter flexibility enables reliable assembly without requiring extremely tight manufacturing precision.
3Adaptability or versatility
If a modular configuration with separate reinforcement members is used, then the adaptability for reinforcement at one or both ends improves, but the ease of manufacture decreases
Solution Approach 1:
The reinforcement member is designed as a universal component that can be used at either end of the container or both ends, depending on the specific application requirements. This multi-functional design allows a single reinforcement part to serve multiple positions and purposes, maintaining ease of manufacture while providing configuration flexibility.

AI summary
A container for holding at least one article includes a body having a front wall, a back wall, and at least one side wall extending at least partially around an interior of the container, a lid repositionable between a closed position at least partially overlying the body and an open position at least partially raised away from the body, the lid comprising a lid panel and a lid flange extending upwardly from the lid panel to at least partially form a lid recess, a reinforcement member at least partially received in the lid recess, and a closed bottom comprising a bottom panel attached to a portion of the body.
