Casket Lid Support Bracket for Closing Force Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Casket lids can be damaged when a lid support brace is locked and the lid is pressed down to close, as the force exerted on the lid edge causes shear stress, leading to potential damage.
Innovation Solution
A support bracket with a first leg mounted to the interior surface of the casket lid's crown rail, a second leg connected to the lid support brace, and a support rib extending towards the second leg, which dissipates the closing force through the crown rail, preventing damage to the lid edge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lid support brace is used to prop open the casket lid, then the lid can be kept open during viewing, but the brace can cause damage to the casket lid when force is applied to close the lid while the brace is locked
Solution Approach 1:
The support bracket acts as an intermediary component between the lid support brace and the casket lid. It transfers the closing force from the vulnerable lid edge to the stronger crown rail structure, preventing direct damage to the lid while maintaining the lid support function.
Solution Approach 2:
The support bracket divides the force transmission path into separate structural elements: the first leg attaches to the crown rail, the second leg connects to the brace, and the support rib provides internal reinforcement. This segmentation allows force to be distributed to appropriate structural components rather than concentrating stress at the lid edge.
2Stability of the object's composition
If the lid support brace is locked to prevent inadvertent closing, then the lid remains securely open, but the casket lid cannot withstand force applied to close it
Solution Approach 1:
The support bracket serves as a mediator that decouples the stability function from the strength function. The locked brace provides positional stability through the support bracket, while the bracket itself handles the strength requirement by routing forces to the crown rail, allowing the lid to withstand closing forces without compromising stability.
Solution Approach 2:
The support bracket introduces a new structural dimension by extending from the crown rail interior surface to the brace connection point. This additional dimensional element creates a force transmission pathway that bypasses the lid edge, enabling the system to handle closing forces while maintaining lid position stability.

AI summary
A support bracket for a casket lid of a casket includes a first leg configured to mount to an interior surface of a crown rail of the casket lid, a second leg connected to the first leg and configured to connect to a brace that that braces the casket lid, and a support rib connected to the first leg and extending in a direction toward the second leg.
