Foldable Casket Lid With Diagonal Corner Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lightweight foldable caskets often lack sufficient strength to support multiple stacked units, leading to damage or crushing of the lids during storage and transportation.
Innovation Solution
A corrugated paperboard lid structure with diagonal corner supports is designed to provide structural strength, allowing for safe stacking of assembled caskets by extending from the top panel to the side panels, eliminating the need for adhesives or additional fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If lightweight corrugated paperboard is used for the casket, then cost and weight are reduced, but structural strength is insufficient to support stacking
Solution Approach 1:
The lid structure combines corrugated paperboard with integrated corner supports formed from the same material, creating a composite structure where the corrugated core provides lightweight strength and the solid corner panels provide stacking support. This composite approach maintains the lightweight advantage while achieving sufficient structural strength for stacking multiple caskets.
Solution Approach 2:
The lid is segmented into functional zones: the corrugated paperboard panels provide the base lightweight structure, while four separate corner support panels are integrated at the corners. This segmentation allows each zone to perform its specialized function - the corrugated sections maintain flexibility and light weight, while the solid corner panels provide concentrated strength for stacking loads.
2Ease of operation
If the lid is made lightweight for easy assembly, then assembly ease is improved, but the lid cannot support the weight of stacked caskets
Solution Approach 1:
The lid applies local quality by concentrating structural reinforcement only at the corner regions where stacking loads are applied, rather than making the entire lid heavy. The corner supports are strategically positioned to bear the brunt of stacking forces, while the rest of the lid panels remain lightweight for easy assembly and handling.
3Productivity
If multiple caskets are stacked for efficient storage, then storage efficiency is improved, but the lightweight lids bend or crush under weight
Solution Approach 1:
The corner supports act as pre-positioned structural reinforcements that anticipate and prepare the lid to withstand stacking loads before the caskets are actually stacked. By having these supports integrated in advance, the lid is pre-conditioned to resist bending and crushing forces that will be applied during storage and transportation.

AI summary
A casket includes a container configured to receive a deceased, the container including a bottom and sides defining at least a part of a casket interior. The casket further includes a lid disposed on the container to cover the casket interior. The lid is formed from a corrugated paperboard blank folded into a lid structure. The lid structure includes a top panel, at least two side panels and at least one end panel, and a plurality of supports extending to a height of the side panels. Each of the corner supports includes at least a first panel extending diagonally from a first location proximate one of the side panels to a second location proximate the at least one end panel. The first panel has a first length corresponding to the height of the side panels.
