Solution Overview

Problem

Existing mounting assemblies for playback devices, particularly those with upward-firing transducers, struggle to maintain orientation and prevent overheating due to increased weight and the need for adjustability, leading to potential audio output and thermal issues.

Innovation Solution

An adjustable mounting assembly with a two-part collar and multi-part body that allows for adjustability while supporting significant weight, featuring a threaded engagement that locks in place to prevent unwanted rotations and enhance stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional ball joint mounting assembly is used, then adjustability and ease of installation are improved, but the structure cannot support significant weight and maintain stability

Engineering Contradiction:
Improveease of installationVSAvoidweight support capacity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The mounting assembly is divided into multiple components: a fixed mounting bracket attached to the wall, and a separate adjustable arm assembly that can be positioned and locked. This segmentation allows the fixed bracket to bear the structural load while the adjustable arm provides positioning flexibility, resolving the contradiction between strength and ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting assembly incorporates adjustable elements that allow the arm to be positioned at different angles and heights, then locked in place. This dynamic adjustability during installation followed by fixed positioning during use provides both ease of operation and stable weight support, addressing the technical contradiction.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If the mounting assembly is made rigid to prevent rotation, then stability is improved, but adjustability is reduced

Engineering Contradiction:
Improvemounting stabilityVSAvoidadjustability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The mounting assembly is designed to be adjusted and positioned during the installation phase, then locked into a fixed configuration. This preliminary adjustment action allows the structure to achieve both adjustability (during setup) and stability (during use), resolving the contradiction between these two properties.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system transitions from a dynamic, adjustable state during installation to a static, stable state during operation. The locking mechanism enables this transition, providing adjustability when needed and stability when required, thus resolving the contradiction between adaptability and stability.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the playback device is mounted in undesirable orientations, then installation flexibility is improved, but audio output quality and thermal management deteriorate

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidaudio output quality
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The mounting assembly incorporates features specifically designed to constrain the playback device in certain orientations while allowing flexibility in others. By controlling the orientation locally at the mounting interface, the system ensures proper audio output and thermal management while maintaining installation flexibility, resolving the contradiction between adaptability and reliability.

Inventive Principle:
Principle #3Local quality

AI summary

An adjustable mounting assembly includes (i) a housing with front and rear collars joined by a threaded engagement, the rear collar including teeth oriented toward the front collar, (ii) a front body part extending outwardly through an opening in the front collar, (iii) an intermediate body part coupled to the front body part, and (iv) a rear body part coupled to the intermediate body part, the rear body part including teeth oriented toward the rear collar, the mounting assembly adjustable such that (a) when the threaded engagement is tightened, the teeth of the rear body part are positioned in an interlocking engagement with the teeth of the rear collar, preventing rotation about a pitch axis of the mounting assembly, and (b) when the threaded engagement is loosened, the teeth of the rear body part are disengageable from the teeth of the rear collar, allowing rotation about the pitch axis.
