Solution Overview

Problem

Existing tombstone devices lack an integrated audio unit capable of emitting a pre-recorded eulogy to enhance memorialization, unlike existing multimedia and lamp devices that only provide illumination.

Innovation Solution

A clamp with adjustable width, integrating an audio unit that stores and emits a pre-recorded eulogy, powered by a rechargeable battery and solar panel, allowing visitors to hear the eulogy when actuated.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a clamp with adjustable width is used to attach the audio unit to tombstones of varying sizes, then the adaptability to different tombstone dimensions is improved, but the device complexity increases due to the sliding mechanism

Engineering Contradiction:
Improveadaptability to different tombstone dimensionsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clamp incorporates a sliding mechanism that allows the width to be dynamically adjusted to match different tombstone dimensions. The first jaw slides relative to the second jaw along a sliding path, enabling the clamp to adapt to various sizes while maintaining a secure attachment.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If an audio unit is integrated into the clamp to emit pre-recorded eulogies, then the memorialization function is enhanced, but the device complexity increases due to additional electronic components

Engineering Contradiction:
Improvememorialization functionVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The audio unit is integrated directly into the clamp structure, merging the attachment function with the audio playback function. The audio unit includes a housing, speaker, and control circuitry that are combined with the clamp's mechanical components, creating a unified device that both attaches to the tombstone and delivers the eulogy.

Inventive Principle:
Principle #5Merging (Combining)

3Duration of action of moving object

If a solar panel is added to power the audio unit for extended functionality, then the duration of action is improved, but the device complexity increases due to power management systems

Engineering Contradiction:
Improveduration of actionVSAvoiddevice complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The solar panel is positioned on the outer surface of the clamp to capture sunlight and convert it to electrical energy, which is stored in a battery to power the audio unit. This self-powered system allows the audio unit to operate for extended periods without external power sources, providing continuous memorialization functionality.

Inventive Principle:
Principle #25Self-service

AI summary

A tombstone audio device for enhancing memorializing a decedent at a tombstone includes a clamp that has a first jaw which is slidably engaged to a second jaw thereby facilitating the clamp to have an adjustable width. In this way the clamp can be attached to a tombstone. An audio unit is provided and the audio unit is integrated into the clamp. The audio unit stores a pre-recorded message comprising a eulogy of the decedent associated with the tombstone. The audio unit emits the pre-recorded message when the audio unit is actuated to facilitate a visitor of the tombstone to hear the eulogy.
