Magnetic Sign Faceplate Assembly for Easy Insert Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sign and display systems face difficulties in inserting and removing inserts due to the design requiring sliding into thin slots, and lack protection for the inserts.
Innovation Solution
A sign and display system comprising a faceplate with a recessed back surface and internal edges, a lens that fits within the recess, and a backing plate with magnets to secure the components together, allowing for easy insertion and removal of inserts while providing protection through a ferromagnetic backing plate and sticky mediums for wall attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If inserts are slid into thin slots for attachment, then the sign system can display information, but it becomes difficult to insert and remove the inserts
Solution Approach 1:
The sign system is divided into separate components: a faceplate with a recess, a removable insert, and a backing plate with magnets. This segmentation allows the insert to be easily detached and reattached without requiring sliding into thin slots, directly solving the ease of operation problem while maintaining a simple overall structure.
Solution Approach 2:
The recess in the faceplate acts as an intermediary space that receives and holds the insert. This recessed structure provides a natural receiving area for the insert, eliminating the need for thin slots and making insertion and removal straightforward operations.
2Reliability
If no lens is used to protect the insert, then the structure remains simple, but the insert lacks protection
Solution Approach 1:
The lens is nested within the recess of the faceplate, fitting into the existing space without requiring additional external structures. This nested arrangement provides protection for the insert while adding minimal complexity to the overall system design.
Solution Approach 2:
The lens acts as a thin protective film or shell that covers the insert within the recess. This thin protective layer provides reliability and protection for the insert while maintaining a simple structure that does not significantly increase device complexity.
3Strength
If magnets are embedded in the faceplate to secure components, then the attachment is secure, but the magnets may interfere with insert insertion
Solution Approach 1:
The magnets are positioned at specific locations within the recessed back surface of the faceplate, away from the opening where inserts are inserted. This localized placement ensures strong attachment strength while avoiding interference with the ease of insert insertion and removal operations.
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 system enables easy insertion and removal of inserts and protects them with a lens, ensuring secure attachment to the wall, enhancing usability and durability.
Implementation Method 1
The at least one magnet exerts a force on the backing plate to maintain the faceplate, lens, and backing plate together
Implementation Method 2
sticky mediums for wall attachment

AI summary
A sign and display system including a faceplate, lens, backing plate, and at least one magnet is described. 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. The lens may include one or more edge protrusions configured to enter one or more small recesses in the side of the faceplate recess to secure the lens to the faceplate. When the lens and backing plate are positioned in the recess of the faceplate, the one or more magnets exert a force on the backing plate to secure the faceplate and lens to the backing plate. An insert capable of displaying text and/or graphics can also be positioned between the lens and backing plate in the recess of the faceplate.
