Angularly Adjustable Bracket Assembly for Speaker Cabinets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio speaker systems face challenges in providing unobtrusive and secure mounting solutions that allow for easy angular adjustment and protection against damage or theft, especially during construction stages, while maintaining hidden wiring and moisture protection.
Innovation Solution
A bracket assembly comprising an inner and outer bracket with a ball joint connection that allows for wide angular adjustment and automatic electrical engagement, featuring non-uniform groove and tab structures for secure mechanical and electrical connections, along with sealing elements to prevent moisture ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed mounting system is used to secure speaker cabinets, then the mounting is simple and stable, but the angular orientation cannot be adjusted
Solution Approach 1:
The mounting system transitions from a fixed rigid connection to a dynamic adjustable connection using a ball joint mechanism. The ball joint allows the speaker cabinet to be mounted at multiple angular orientations while maintaining secure attachment, enabling both stability and adaptability in the mounting system.
Solution Approach 2:
The mounting system is divided into separate components: an inner bracket, an outer bracket, and a ball joint connector. This segmentation allows each component to perform its specific function while enabling angular adjustment through the ball joint, resolving the contradiction between simplicity and adjustability.
2Ease of operation
If electrical connectors are exposed for easy connection, then electrical engagement is simple, but the wiring is visible and components are vulnerable
Solution Approach 1:
The electrical connectors are nested within the bracket assembly structure. The inner bracket contains the electrical connectors, which are automatically engaged when the outer bracket is attached to the inner bracket. This nesting hides the wiring and connectors from view while maintaining easy automatic connection.
Solution Approach 2:
The electrical connectors are designed to automatically engage with each other when the brackets are assembled, eliminating the need for manual wiring connections. This self-service feature simplifies the installation process while keeping the electrical connections hidden and protected within the bracket structure.
3Strength
If a simple bracket structure is used for mounting, then the manufacturing is easy and cost is low, but the mounting security and durability are insufficient
Solution Approach 1:
The mounting system merges mechanical connection features and electrical connection features into a single integrated bracket assembly. The inner and outer brackets combine structural support functions with electrical connector housing, providing both mounting security and electrical connectivity without requiring separate components, thus maintaining ease of manufacture while improving strength.

AI summary
A bracket assembly is used to secure a housing to a support structure such as a post, wall or ceiling. The bracket assembly includes an inner bracket, an outer bracket and a connector. The inner bracket is configured to be mounted on the support structure separately from the outer bracket, and the outer bracket is configured to be quickly mounted on the inner bracket. The outer bracket and connector are joined by a ball and socket joint. Angular adjustment of the ball relative to the socket is made prior to mounting of the outer bracket on the inner bracket, and the desired orientation is maintained using a clamping assembly. The bracket assembly includes sealing features that prevent moisture from entering the assembly.
