Solution Overview

Problem

Existing audio equipment supports suffer from a lack of rigidity due to restricted design, leading to inadequate suppression of vibrations and subsequent deterioration in sound quality.

Innovation Solution

An audio equipment support design featuring a main body with a protrusion and a counterpart body with a recess, where the restriction member is fixed to the main body and includes a through-hole to limit the distance between the main and counterpart bodies, allowing for increased rigidity and effective vibration suppression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the restriction member is fixed to the counterpart body and configured to surround the protrusion, then the distance between main body and counterpart body is restricted, but the main body lacks rigidity and stability

Engineering Contradiction:

Improvestability of supportVSAvoidrigidity of main body

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The restriction member is inverted from being fixed to the counterpart body to being fixed to the main body instead. This inversion allows the main body to maintain its rigidity while still achieving the distance restriction function, thereby resolving the contradiction between stability and rigidity.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The design transitions from a configuration where the restriction member surrounds the protrusion to one where the counterpart body passes through a through-hole of the restriction member. This dimensional change allows the main body to extend beyond the counterpart body, enhancing rigidity while maintaining the distance restriction capability.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If the main body width is restricted to be not greater than the counterpart body width, then the distance restriction is achieved, but vibration suppression is insufficient leading to sound quality deterioration

Engineering Contradiction:

Improvevibration transmissionVSAvoidrigidity of main body

Core Design Contradiction:

Object-affected harmful factorsVSStrength

Solution Approach 1:

By inverting the attachment configuration of the restriction member to be fixed on the main body rather than the counterpart body, the main body can now extend beyond the counterpart body width. This enables the main body to function as an effective vibration suppression element, reducing harmful vibrations and improving sound quality while maintaining the distance restriction function.

AI summary

An audio equipment support include; a main body including a protrusion and being configured to be attachable to an audio equipment housing; a counterpart body including an outer edge and a recess contacting the protrusion, the outer edge of the counterpart body being positioned inward of an outer edge of the main body when viewed from a direction in which the protrusion and the recess are aligned; and a restriction member fixed to the main body and spaced apart from the counterpart body, the restriction member including a through-hole through which the counterpart body passes and being configured to restrict a distance between the main body and the counterpart body from reaching or exceeding a predetermined length.
