Picture Frame Magnetic Assembly for Quick Picture Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing picture frames often require complex assembly and risk arrangement errors when exchanging pictures, making the process slow and prone to mistakes.
Innovation Solution
A picture frame design utilizing magnetic forces to securely attach the back wall and passe-partout to the profile frame, allowing for quick and simple picture exchange, with magnets embedded in the passe-partout and back wall, and optional glass pane attachment via pins or pressure springs, enabling easy alignment and secure fixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If magnets are used to fix the back wall and passe-partout in the profile frame, then the picture exchange process is simplified and accelerated, but the risk of arrangement errors and slipping during insertion increases
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, clips, adhesives) with a magnetic field-based retention system. Magnets embedded in the profile frame create magnetic attraction forces that hold the passe-partout and back wall in place, allowing for tool-free, rapid picture exchange while maintaining secure attachment during normal use
Solution Approach 2:
The patent modifies the physical parameters of the magnetic components by using strongly magnetized, thin magnet plates with specific magnetic field strengths. This allows the magnets to provide sufficient holding force for secure attachment while being thin enough to not interfere with the picture exchange process or create protrusions that could cause alignment errors
2Reliability
If the passe-partout and glass pane are firmly connected to the profile frame, then the risk of slipping during picture insertion is reduced, but the complexity of assembling and disassembling the frame increases
Solution Approach 1:
The patent replaces complex mechanical connection systems (multiple screws, clips, or interlocking mechanisms) with a magnetic field-based retention system. The magnetic attraction between the magnets in the profile frame and the ferromagnetic materials in the passe-partout and back wall provides firm connection during normal use, while allowing for simple manual removal when picture exchange is needed
Solution Approach 2:
The magnetic connection system serves multiple functions simultaneously: it firmly holds the passe-partout and glass pane in place during normal display, provides sufficient attraction to prevent slipping during picture insertion, and allows for easy manual disengagement when picture exchange is required. This single magnetic system replaces what would otherwise require multiple separate mechanical fastening mechanisms
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
Significantly simplifies and accelerates the process of exchanging pictures by reducing the risk of slipping and ensuring correct re-insertion, with the magnets providing strong attraction and the frame's design preventing lateral displacement of the back wall.
Implementation Method 1
The picture frame uses magnetic forces of attraction, at least one magnetic pairing that fixes the back wall with the pictures or photos against the passe-partout and, if present, also the glass pane in the profile frame
