Device for hanging objects on a vertical surface and a method of using the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for hanging pictures or panels on vertical surfaces fail to maintain alignment and levelness due to disturbances, requiring constant readjustment and being difficult for novices to use effectively.
Innovation Solution
A two-piece hanger assembly with a surface portion and an object portion, featuring integral nubs and marking tabs that allow precise leveling and alignment, marking the correct attachment points on the wall, and securing the object in place without mechanical fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional nails and wires are used to hang pictures, then the hanging method is simple and requires minimal tools, but the pictures cannot maintain alignment and levelness when the wall is disturbed
Solution Approach 1:
The hanging device is divided into two separate brackets: a surface bracket that attaches to the wall and an object bracket that attaches to the picture. These brackets can be installed independently and then connected through nested channels, allowing each component to be optimized for its specific function while maintaining overall simplicity
Solution Approach 2:
The object bracket's channel is designed to nest within the surface bracket's channel. This nested configuration provides structural stability and maintains alignment between the picture and wall while using minimal material, resolving the contradiction between reliability and device complexity
2Measurement precision
If precise leveling and alignment are achieved through premeasurement and readjustment, then accurate positioning is obtained, but the process becomes time-consuming and difficult for novices
Solution Approach 1:
The brackets are pre-configured with channels and nubs positioned at optimal locations for leveling and alignment. The surface bracket includes a level surface and the object bracket includes a level surface that mate together, eliminating the need for on-site measurement and adjustment while ensuring precise positioning
Solution Approach 2:
The interlocking channel and nub design automatically self-aligns the picture to the wall when the brackets are connected. The physical geometry of the nested components guides proper positioning without requiring user measurement or adjustment, making the system both precise and quick to install
3Ease of operation
If the hanging device allows easy installation without fasteners, then ease of operation is improved, but the stability under disturbance may be compromised
Solution Approach 1:
The channel and nub connection allows for slight dynamic adjustment while maintaining stability. The nested configuration provides mechanical interlocking that resists disturbance forces while still allowing for easy installation and removal without fasteners
Solution Approach 2:
The surface bracket and object bracket are merged through the nested channel connection, creating a unified hanging system that is both easy to install and stable under disturbance. The combination of the two brackets provides the benefits of simple installation with the reliability of a secure connection

AI summary
A hanger assembly having separable surface and object brackets that can slidably engage in a nested position without fasteners. The nested position is formed through the engagement of opposing channels of the respective surfaces of the surface and object brackets. The surface bracket has marking tabs for impressing on a vertical surface a selected orientation of the object that is connected to the object bracket, which in turn is nested with the surface bracket. Once the vertical surface is impressed by the marking tabs, the surface and object brackets can be un-nested and the surface bracket mounted to the vertical surface with the guidance impressions left my the marking tabs. Then the surface and object brackets can be re-nested for installation of the object against the vertical surface. The object is not limited to pictures or panels, and can be irregularly shaped articles.
