Casket Insert Height Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rental casket systems face challenges in minimizing space usage while allowing easy insertion, removal, and height adjustment of the insert within the casket, which are essential for presenting the deceased in a tasteful manner without compromising the presentation space.
Innovation Solution
The rental casket system incorporates a casket with rollers on the bottom panel for easy insertion and removal of the insert and a height adjustment mechanism using a threaded shaft, worm nut, and crossbar that directly engages the insert, eliminating the need for additional support components and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rollers are positioned along the bottom of the casket to enable the insert to be rolled into and out of the casket, then ease of operation is improved, but volume of stationary object worsens due to space taken by rollers
Solution Approach 1:
The patent employs rollers that can be dynamically positioned and adjusted within the casket structure. The rollers are mounted on adjustable mechanisms that allow them to be moved out of the way during insertion/removal operations and then repositioned to minimize space occupation when not in use, thus maintaining ease of operation while optimizing space utilization.
2Ease of operation
If a height adjustment mechanism is included to raise the head portion of the insert, then ease of operation is improved, but volume of stationary object worsens due to space taken by the mechanism
Solution Approach 1:
The height adjustment mechanism is designed with nested components where the adjustment apparatus is housed within or alongside the existing casket structure. The threaded shaft, worm nut, and crossbar assembly is integrated into the casket's internal framework, allowing the mechanism to be compact and minimally intrusive while still providing full height adjustment functionality.
3Reliability
If the height adjustment mechanism is designed to avoid interference with insertion and removal of the insert, then reliability is improved, but device complexity worsens
Solution Approach 1:
The height adjustment mechanism is segmented into distinct functional modules: a threaded shaft for vertical movement, a worm nut for secure engagement and positioning, and a crossbar for direct contact with the insert. This segmentation allows each component to perform its specific function independently, reducing overall complexity while ensuring reliable operation that does not interfere with insert insertion or removal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for efficient space utilization within the casket, facilitating easy handling and adjustment of the insert while maintaining a pleasant presentation of the deceased, thereby enhancing the presentation and usability of the rental casket system.
Implementation Method 1
The worm nut rotatably engages the threaded shaft and translates rotational movement into axial movement along the shaft

AI summary
A casket system includes a casket container and a height adjustment mechanism. The casket container has a bottom, a head end panel, a foot end panel, and rollers supported by the bottom. The height adjustment mechanism includes a threaded shaft, a worm nut, and a crossbar. The threaded shaft extends at least partly in the vertical direction. The shaft is rotatably coupled to the casket container proximate the head end panel. The worm nut is rigidly secured to the crossbar. The worm nut rotatably engages the threaded shaft and translates rotational movement into axial movement along the shaft. The crossbar includes spaced-apart extensions extending from an edge thereof away from the head end panel. The spaced-apart extensions are configured to contact and engage a casket insert that is sized and configured to receive a deceased. The axial movement of the worm nut causes the crossbar to move vertically with respect to the head end panel.
