System and method for wall mounting with a rotating bushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall mounting methods often result in moisture entry and degradation, especially in wet environments, and rely on single anchor points that can lead to force concentration and failure, with limited hold strength in low-strength materials.
Innovation Solution
A wall mounting system featuring a rotating bushing assembly and a Z-bar configuration that distributes mechanical load across multiple adhesive and anchor points, using machine threads for increased surface area and integrating the fastening member into the wall for enhanced hold strength, while allowing for flexible set screw alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If anchor screws are inserted into low strength materials such as plaster or drywall, then installation is easier, but hold strength is limited to less than five lbf
Solution Approach 1:
The mounting system divides the load-bearing function into multiple anchor screws distributed across the wall surface, rather than relying on a single anchor point. Each anchor screw provides partial support, collectively achieving high hold strength in low-strength materials
Solution Approach 2:
The system transitions from single-point anchoring to multi-point distributed anchoring across the wall surface. By spreading anchor screws across multiple locations, the system achieves high hold strength without requiring penetration into high-strength materials like wall studs
2Strength
If wall anchors or helical anchors are used to increase hold strength in low strength materials, then hold strength increases to five to forty lbf, but the mounting still relies on individual penetrating anchor points that create force concentration
Solution Approach 1:
The system further segments the load distribution by using multiple anchor screws instead of single wall anchors. This segmentation reduces force concentration at any single point, improving reliability while maintaining hold strength in low-strength materials
Solution Approach 2:
Each anchor screw is positioned to optimize local load distribution in the wall material. The distributed arrangement ensures that no single location bears excessive force, preventing local failure while maintaining overall mounting reliability
3Strength
If anchor screws are inserted into high strength materials such as wall studs, then hold strength increases to fifty lbf, but the mounting relies on one or a few penetrating anchor points that create force concentration areas
Solution Approach 1:
The system segments the anchoring function into multiple anchor screws distributed across the wall, eliminating reliance on a few penetrating anchor points. This segmentation distributes force evenly, preventing force concentration areas that could cause wall material or accessory item deformation
Solution Approach 2:
The system transitions from point-based anchoring to area-based distributed anchoring. By spreading multiple anchor screws across the wall surface, the system maintains high hold strength while eliminating force concentration risks associated with penetrating anchor points
4Ease of manufacture
If drilling holes into the wall is performed to install anchor screws, then accessory items can be mounted to the wall, but moisture entry points are created that cause wall degradation, mold, or mildew in wet environments
Solution Approach 1:
The system uses surface-mounted anchor screws that do not require deep penetration into the wall. These shallow-mounted anchors can be removed or replaced without causing significant wall damage, and the mounting system can be designed to maintain waterproofing while allowing installation
Solution Approach 2:
The system minimizes wall penetration at each anchor point while achieving sufficient hold strength through distributed anchoring. By using multiple shallow anchors instead of deep penetrating anchors, the system reduces moisture entry risk while maintaining installation ease

AI summary
A wall mounting system is provided including a fastening member including one or more mounting studs and one or more anchor apertures. The fastening member is configured to be anchored to a support structure by one or more fasteners disposed through the one or more anchor apertures. The wall mounting system also includes a bushing assembly including an inner portion including a through hole configured to receive a mounting stud and an outer portion configured to rotate about the inner portion and including at least one set screw aperture configured to align with a set screw aperture of an accessory sleeve and receive a set screw. Rotation of the outer portion about the inner portion enables indexing of the set screw aperture about a longitudinal axis of the bushing assembly.
