Ball-Joint Wall Bracket for Uneven Surface Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall brackets struggle to adapt to uneven surfaces, requiring additional shims for installation and limiting their application, especially in corner mounting scenarios.
Innovation Solution
A wall bracket design featuring a ball joint with a ball socket and ball head, allowing a swivel angle of up to 50°, enabling flexible alignment and compensation for surface unevenness without the need for shims, and a locking mechanism to secure the position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid connection between anchor element and fastening element is used, then structural strength is improved, but adaptability to uneven surfaces deteriorates
Solution Approach 1:
The ball joint connection allows dynamic adjustment of the fastening element relative to the anchor element, enabling the system to adapt to uneven wall surfaces while maintaining structural integrity through controlled movement rather than rigid fixation
2Adaptability or versatility
If additional shims are used to compensate for surface unevenness, then adaptability to uneven surfaces is improved, but device complexity deteriorates
Solution Approach 1:
The ball joint integrates the adaptation function directly into the connection mechanism between anchor and fastening elements, eliminating the need for separate shim components and reducing overall device complexity while maintaining adaptability to uneven surfaces
3Ease of operation
If a ball joint with large swivel angle is used, then ease of alignment is improved, but stability under tensile force deteriorates
Solution Approach 1:
The ball socket geometry is designed with specific local characteristics - a narrow opening that restricts movement in certain directions while allowing alignment rotation, creating different mechanical properties in different orientations to simultaneously enable ease of alignment and stability under load

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy installation on uneven surfaces, simplifies alignment, and allows use as a corner connector, ensuring secure fixation without additional components.
Implementation Method 1
The bearing section on the anchor element side and the bearing section on the fastening element side form a ball joint with a ball socket and a ball head
Implementation Method 2
The contact surface on the socket side has the shape of a spherical segment, and the contact surface on the ball head side also has the shape of a spherical segment
