Solution Overview

Problem

Existing devices for scattering cremated ashes result in a brief ash scattering event, failing to provide a visually appealing and dramatic effect as desired by relatives and friends of the deceased.

Innovation Solution

A device with a release mechanism comprising an annular outer and inner member that translates relative to each other along a common longitudinal axis, controlling the release of cremated ashes through a controlled outlet, utilizing a linear actuator and a controller for automated operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If cremated ashes are released rapidly from the device, then the release mechanism is simple and quick to operate, but the ash scattering event lasts only a short amount of time, failing to provide a visually appealing effect

Engineering Contradiction:
Improveduration of ash scattering eventVSAvoidrelease speed of cremated ashes
Core Design Contradiction:
Duration of action of moving objectVSProductivity

Solution Approach 1:

The release mechanism uses a dynamically adjustable annular gap between the inner and outer members to control the release rate. The gap width can be varied during operation, transitioning from a closed position (no release) to partially open (controlled release) to fully open positions (maximum release), enabling prolonged controlled scattering of ashes over time rather than rapid instantaneous release

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mechanism changes the physical parameter of the outlet opening area by translating the inner member radially relative to the outer member. This adjusts the annular gap width, thereby controlling the release rate parameter of the cremated ashes, allowing the duration of the scattering event to be extended while maintaining visual appeal

Inventive Principle:
Principle #35Parameter changes

2Duration of action of moving object

If the release mechanism uses a simple open/close valve, then the device complexity is low, but the control over release rate is insufficient to provide a prolonged visual effect

Engineering Contradiction:
Improveduration of ash scattering eventVSAvoidcomplexity of release mechanism
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The release mechanism is segmented into an outer member (outlet structure) and an inner member (movable closure element) that can be independently positioned. This segmentation allows for continuous adjustment of the annular gap between the two members, providing graduated control over the release rate while maintaining a relatively simple overall structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner member is made movable relative to the outer member along the radial direction, transforming a static simple valve into a dynamic adjustable mechanism. This adds control capability for prolonging the scattering event while keeping the structural complexity manageable through straightforward translational motion

Inventive Principle:
Principle #15Dynamics

AI summary

A device for automatically releasing cremated ashes, comprising: a chamber for containing cremated ashes; and a release mechanism configured to selectively release cremated ashes contained in the chamber to the external environment, the release mechanism comprising an annular outer member, and an inner member at least partially radially inward of the outer member, the outer member comprising an outlet from the chamber. The release mechanism is configured to translate the inner member and the outer member relative to each other along a common longitudinal axis from a first relative position, in which release of cremated ashes in the chamber through the outlet is inhibited, to a second relative position, in which release of cremated ashes in the chamber through the outlet is enabled. In the first relative position, the inner member is in contact with the outer member so as to cover the outlet. In the second relative position, the inner member is spaced from the outer member.
