Casket Backer Board Snap Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of casket top interiors is complex and unreliable due to the need for additional cardboard or wooden supports to maintain the shape of decorative rolls, which complicates attachment mechanisms and increases manufacturing time.
Innovation Solution
A foldable snap locking backer board is used to support the rolls and center panel, featuring a center wall and side walls that engage nooks in the casket lid under tension, providing a reliable and easy-to-assemble solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional cardboard or wooden supports are used to maintain the shape of decorative rolls, then the structural reliability is improved, but the device complexity and manufacturing time increase
Solution Approach 1:
The backer board merges the support function and the decorative roll formation into a single integrated component. The corrugated fiberboard structure combines the rigid support needed for rolls with the decorative finishing, eliminating the need for separate cardboard or wooden supports while maintaining structural reliability.
Solution Approach 2:
The invention uses corrugated fiberboard as a composite material that provides both structural support and decorative capability. The fluted inner layer provides rigidity and support for the rolls, while the outer layer can be finished to match decorative requirements, replacing multiple separate support components.
2Reliability
If additional cardboard or wooden supports are used to maintain the shape of decorative rolls, then the structural reliability is improved, but the manufacturing time increases
Solution Approach 1:
By combining the support function and decorative roll formation into a single backer board component, the manufacturing process is simplified. The integrated corrugated fiberboard structure eliminates multiple assembly steps required for separate supports, reducing manufacturing time while maintaining reliability.
Solution Approach 2:
The backer board is pre-formed with the necessary corrugated structure and decorative finishing before installation. This preliminary preparation of the support structure eliminates the need for on-site assembly of multiple support components, reducing overall manufacturing and installation time.
3Reliability
If complicated attachment mechanisms are used to secure the rolls, then the reliability is improved, but the ease of manufacture decreases
Solution Approach 1:
The attachment function is merged into the backer board structure itself through the corrugated fiberboard design. The fluted structure provides inherent mechanical interlocking and positioning for the rolls, eliminating the need for separate complicated attachment mechanisms while maintaining secure retention.
Solution Approach 2:
The corrugated fiberboard backer board is self-attaching through its inherent structural design. The fluted inner layer and outer layer work together to automatically position and secure the rolls without requiring additional fasteners or complex attachment mechanisms, simplifying manufacturing while ensuring reliability.

AI summary
A casket includes a casket body, at least a first lid, and a backer board. The casket body is configured to receive an adult human body in the supine position. The lid has a first bottom interior ledge defining a first nook in an underside of the lid, and a second bottom interior ledge defining a second nook in the underside of the lid. The backer board is formed of a pliable material, and includes a center wall having a first edge and an opposite second edge. The backer board also includes a first side wall extending away from the first edge, and a second side wall extending away from the second edge. The first side wall and the second side wall are configured to engage, respectively, the first and second nooks, under a tension configured to hold the center wall in a predetermined position.
