Magnetic Sign and Display Assembly for Easy Insert Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sign and display systems face difficulties in easily inserting and removing inserts due to the design, particularly in systems without a protective lens, which can damage the content displayed.
Innovation Solution
A sign and display system comprising a faceplate, a lens, and a backing plate with embedded magnets that securely hold the components together, allowing for easy insertion and removal of inserts while protecting the content with a transparent or translucent lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If inserts are permanently or removably attached to sign systems using slots or mechanical fasteners, then the inserts can be securely held, but it becomes difficult to insert and remove these inserts
Solution Approach 1:
The patent replaces traditional mechanical attachment systems (slots, clips, screws) with a magnetic field-based attachment system. Magnets embedded in the faceplate create magnetic attraction forces that securely hold ferromagnetic inserts without requiring physical interlocking mechanisms, enabling easy insertion and removal while maintaining secure attachment.
Solution Approach 2:
The patent changes the attachment mechanism from mechanical interlocking to magnetic field interaction. By utilizing magnetic field strength as the attachment parameter instead of mechanical geometry, the system achieves both secure holding and ease of operation, as inserts can be simply brought near the faceplate to engage magnetically or removed by overcoming the magnetic force.
2Object-affected harmful factors
If no protective lens is used in sign systems, then the structure remains simple, but the displayed content becomes vulnerable to damage
Solution Approach 1:
The patent introduces a protective lens as an intermediary element between the displayed insert and the external environment. This lens serves as a protective barrier against physical damage, dust, and moisture while maintaining optical transparency to preserve the visibility of the displayed content, thus protecting the insert without significantly complicating the overall system structure.
3Force
If magnets are embedded in the faceplate to secure components, then attachment strength is improved, but the faceplate structure becomes more complex
Solution Approach 1:
The patent combines the magnetic attachment functionality with the existing faceplate structure by embedding magnets within the faceplate body or mounting surface. This integration approach incorporates the magnetic field generation directly into the faceplate component itself, providing strong attachment force while minimizing additional structural complexity compared to separate magnetic attachment mechanisms.

AI summary
Sign and display systems including a faceplate, lens, backing plate, and at least one magnet are described. In some embodiments, the faceplate includes a viewing aperture and the back of the faceplate includes a recess in which the at least one magnet is mounted. The recess in the faceplate is configured to receive the lens and backing plate. In some embodiments, the faceplate includes two recesses in the back surface, where the first level recess is configured to receive a backing plate and the second lower level recess is configured to receive the lens. The at least one magnet can be mounted in either a first recessed surface of the first level recess or the backing plate. When the lens and backing plate are positioned in the faceplate, the one or more magnets exert a force to secure the faceplate, lens, and backing plate together.
