Solution Overview

Problem

High-end audio and electronic equipment experiences performance degradation due to vibrational energy transfer from unsupported chassis, which is exacerbated by shelves with unknown energy content, leading to noise and reduced output.

Innovation Solution

The use of energy dissipation devices that create a tortuous energy flow path between equipment and shelves, utilizing a cone component with a large contact area and energy dissipation materials to absorb and dissipate energy, thereby reducing vibration and noise.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high-end audio equipment is placed directly on a shelf, then the equipment is supported and stable, but vibrational energy is transferred from the chassis to the shelf causing noise and performance degradation

Engineering Contradiction:
Improveequipment stabilityVSAvoidvibrational noise
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary energy dissipation device positioned between the equipment chassis and the shelf. This device includes a cover plate that contacts the chassis, a cone component with energy dissipation material, and a base that contacts the shelf. The intermediary structure transfers vibrational energy through a tortuous path and dissipates it as heat, preventing direct transmission to the shelf while maintaining equipment support.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts harmful vibrational energy into beneficial heat energy through the energy dissipation material in the cone component. The material's viscoelastic properties cause it to deform and dissipate mechanical vibration energy as thermal energy, transforming the harmful vibrations into harmless heat that is then conducted away through the base to the shelf.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Object-affected harmful factors

If the equipment chassis is unsupported, then vibrational energy transfer is reduced, but the equipment becomes unstable and performance degrades

Engineering Contradiction:
Improvevibrational energy transferVSAvoidequipment stability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The energy dissipation device serves as a mediator that provides mechanical support while simultaneously managing vibrational energy. The cover plate, cone component, and base structure collectively bear the equipment weight and maintain stability, while the energy dissipation material within the cone component actively manages vibrational energy transfer to the shelf.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The energy dissipation device utilizes composite construction combining rigid structural components (cover plate, cone housing, base) with viscoelastic energy dissipation material in the cone component. This composite approach provides both mechanical support for stability and vibration damping for reduced energy transfer.

Inventive Principle:
Principle #40Composite materials

3Loss of energy

If a typical cone device is used with small contact area, then energy dissipation is provided, but the chassis stiffness is insufficient

Engineering Contradiction:
Improvevibrational energy dissipationVSAvoidchassis stiffness
Core Design Contradiction:
Loss of energyVSStrength

Solution Approach 1:

The patent merges the functions of chassis bracing and energy dissipation into a single integrated cover plate structure. The cover plate contacts a large portion of the chassis bottom surface, providing both structural stiffening and serving as the mounting interface for the energy dissipation cone component, thereby achieving both stiffness and energy dissipation simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

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

Significantly reduces the degradation of audio and electronic equipment performance by minimizing energy transfer to the shelf, resulting in improved output quality.

Implementation Method 1

creates a torturous energy flow path between a piece of equipment and a shelf that supports the piece of equipment and makes direct contact with a large portion (area) of the bottom chassis of the component. This adds stiffness to the chassis and provides for the transfer of energy from the chassis of the component to the shelf below while at the same time providing energy dissipation between the component and the shelf.
