Wire Frame Hanger With Spring Arms for Level Wall Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Locating and preventing tilting of suspended frames, such as picture frames and mirrors, on walls is challenging due to the difficulty in aligning and securing the frames level, especially when they are heavy.
Innovation Solution
A hanger device featuring a center mounting portion with a spring strap and plumb member, where the spring strap's flexible arms hold the wire in place, and the plumb member aids in aligning the device vertically, combined with additional fastening options for increased stability, accommodates both lighter and heavier objects by adjusting to their weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a wire mounting system is used to hang frames on a wall, then the frames can be suspended, but the frames tend to tilt side to side and are difficult to align level
Solution Approach 1:
A plumb line is introduced as an intermediary tool to provide a vertical reference line for alignment. The plumb line hangs freely under gravity to establish a true vertical, against which the frame can be positioned and aligned, solving the difficulty of achieving proper vertical alignment without requiring specialized equipment or complex procedures
Solution Approach 2:
The plumb line incorporates a colored marker or indicator that provides a visual reference point. This visual element makes it easier to see and align the frame vertically, transforming the invisible gravitational force into a visible alignment guide that improves ease of operation
2Strength
If two wall fasteners are used for heavy objects, then the load capacity increases, but the complexity of locating and aligning the frame increases
Solution Approach 1:
The plumb line serves a dual function: it provides the vertical alignment reference and simultaneously indicates when the frame is properly positioned vertically. The weight indicator on the plumb line automatically shows when the frame is level, eliminating the need for separate alignment tools or complex procedures for installing heavy objects
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively reduces side-to-side tilting of frames by flexing under weight, ensuring the frame remains level and securely attached to the wall, even when unbalanced, with the plumb member ensuring proper vertical alignment and additional fasteners providing stability for heavier objects.
Implementation Method 1
the arms of the spring strap are flexible under the weight of the object so flex downwardly from the mounting portion to the ends and wherein the flexing of the arms acts to hold the object when adjusted level to reduce side to side tilting of the object
Implementation Method 2
a plumb member arranged to be mounted on the center mounting portion so as to depend from a support thereon

AI summary
A frame which has a wire extending across a rear of the frame is hung on a wall by an integral flexible spring member shaped to define a center mounting plate fastened to lie flat on the wall and a spring strap standing at right angles to the plate with a pair of arms each extending outwardly from the mounting plate along the wall to a respective side of the mounting plate. The arms receive and locate the wire extending along the arms and depending from ends of the arms to the sides of the frame. The arms can flex and the arms allow longitudinal movement of the wire along the arms to allow movement of the frame side to side relative to the mounting plate. A stiffening rod can be inserted onto the strap.
