Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable wall hangers lack the ability to provide precise vertical and horizontal adjustments with a low profile, requiring multiple mounting points and coarse adjustment capabilities, making them difficult to use for quick and accurate placement.
Innovation Solution
A vertically and horizontally adjustable wall-hanging assembly with a single mounting point, utilizing serrations on two pieces for fine vertical adjustment (down to 1/32 of an inch) and a snap-fit assembly with a bracket for horizontal adjustment, allowing for secure and precise placement of wall hangings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional wall hangers use multiple mounting points with coarse adjustment mechanisms, then the device provides basic adjustment capability, but the adjustment precision is coarse and the device profile is large
Solution Approach 1:
The adjustment mechanism is segmented into two independent systems: vertical adjustment through serrated edges on the mounting bracket and horizontal adjustment through a sliding mechanism with positioning holes. This segmentation allows each direction to achieve fine precision without requiring a large overall device profile, as each segmented component can be optimized independently for its specific adjustment function.
Solution Approach 2:
The patent transitions from coarse single-dimension adjustment to fine two-dimension adjustment by adding the sliding mechanism with multiple positioning holes along the sliding path. This dimensional expansion allows precise positioning in both vertical and horizontal directions independently, achieving high adjustment precision while maintaining a compact profile through efficient spatial utilization.
2Reliability
If wall hangers require multiple mounting points for stability, then the device provides secure mounting, but the installation complexity and time increase
Solution Approach 1:
The mounting system is segmented into a single primary mounting point on the wall that supports the entire bracket assembly, while the adjustment functions (vertical and horizontal) are achieved through mechanical features integrated into the bracket itself rather than requiring additional wall mounting points. This reduces installation time by requiring only one wall penetration while maintaining reliability through the segmented adjustment mechanisms that provide secure positioning.
Solution Approach 2:
The bracket incorporates self-adjusting mechanical features including serrated edges for vertical positioning and a sliding mechanism with positioning holes for horizontal adjustment. These self-service features allow the bracket to achieve precise positioning and secure mounting without requiring multiple pre-drilled wall holes or complex installation procedures, thereby reducing installation time while maintaining mounting reliability.
3Ease of operation
If wall hangers use simple mounting mechanisms for ease of installation, then the device is easy to install, but the adjustment precision and security are reduced
Solution Approach 1:
The adjustment function is segmented into simple mechanical interactions: vertical adjustment through serrated edges that engage with corresponding features, and horizontal adjustment through a sliding mechanism with pre-positioned holes. Each segmented feature is simple to operate individually, yet together they provide fine adjustment precision. The single wall mounting point simplifies installation while the integrated mechanical features maintain adjustment precision.
Solution Approach 2:
The patent utilizes parameter changes in the mechanical engagement features - the serrated edges provide discrete vertical positioning increments, while the sliding mechanism with multiple holes provides discrete horizontal positioning options. These parameter changes allow fine adjustment precision to be achieved through simple mechanical interactions rather than complex mechanisms, maintaining ease of installation while improving adjustment precision.
4Measurement precision
If wall hangers provide coarse adjustment capabilities, then the device structure is simple, but the ability to achieve precise placement is limited
Solution Approach 1:
The adjustment mechanism is segmented into two independent simple systems: vertical adjustment through serrated edges and horizontal adjustment through a sliding mechanism with positioning holes. Each segmented system is structurally simple individually, but their combination achieves fine two-dimensional placement accuracy. This segmented approach avoids the need for a single complex adjustment mechanism while maintaining overall structural simplicity.
Solution Approach 2:
The patent merges two simple adjustment mechanisms (serrated vertical adjustment and sliding horizontal adjustment) into a single integrated bracket assembly. This merging allows fine placement accuracy in both dimensions to be achieved through the combination of simple mechanisms rather than requiring one complex mechanism, thereby improving placement accuracy while minimizing device complexity through efficient integration.

AI summary
An adjustable hanger assembly comprises a hanger, a hanger mount, and a bracket assembly. The hanger comprises a first set of serrations, a center slot, and a hanger tab. The hanger mount comprises a second set of serrations, and a mount aperture. The hanger mount aperture is positioned in coplanar alignment with the center slot axis. The hanger and the hanger mount are assembled together by meshing the serrations in the first and second sets of serrations in a pre-selected position to accommodate users' positioning requirements. A mounting fastener extends through the hanger and the hanger mount for clamping the abutting assembly together and mounting the same to a wall. The hanger assembly is laterally positionable within, and snap-fittable to, the bracket assembly. Together the hanger assembly and the bracket assembly enable the user to adjust the target wall-hanging in two-dimensional space.
