Adjustable Wall Mounting Assembly With Locking Pitch Teeth
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Stability of the object's composition
If the mounting assembly is made rigid to prevent rotation, then stability is improved, but adjustability is reduced
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.
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.
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
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.

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.
