Magnet Retaining Pocket for Adhesive-Free Faceplate Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnet installations for faceplates in control devices are cumbersome and prone to adhesive failure, requiring time-consuming application and losing bonding properties over time.
Innovation Solution
A magnet retaining pocket system with a resilient tongue and bore structure that securely holds magnets without adhesives, allowing for easy installation and removal of faceplate portions using magnetic attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is used to secure magnets to the faceplate, then the magnets can be attached, but the installation becomes time-consuming and cumbersome during production and the adhesive loses bonding properties over time
Solution Approach 1:
The patent removes the adhesive from the system entirely and replaces it with a mechanical retention mechanism. The magnet is secured through a bore structure with a resilient tongue that deflects during insertion and locks the magnet in place, eliminating the time-consuming adhesive application process while maintaining secure attachment.
Solution Approach 2:
The patent replaces the chemical bonding mechanism (adhesive) with a mechanical retention system. The resilient tongue acts as a mechanical latch that physically secures the magnet within the bore, providing both quick installation and durable retention without the drawbacks of adhesive bonding.
2Ease of manufacture
If adhesive is used to secure magnets, then magnets can be attached, but the process is prone to losing bonding properties over time
Solution Approach 1:
The resilient tongue automatically engages with the magnet during insertion and secures it in place without requiring external intervention. The deflection and locking action happens self-service during the insertion process itself, making the manufacturing process simpler and more reliable than adhesive application.
3Reliability
If screws are used to mount the faceplate, then the faceplate can be securely attached, but the screws are unsightly and compromise the decorative appearance
Solution Approach 1:
The patent removes visible fasteners (screws) from the faceplate exterior and replaces them with a magnetic attachment system. The magnets are concealed within the faceplate structure, providing secure attachment while maintaining a clean, decorative appearance without visible hardware.
Solution Approach 2:
The patent replaces the visible mechanical fastening system (screws) with a concealed magnetic attachment system. The magnetic force provides secure attachment between faceplate portions without requiring visible external fasteners, thus maintaining aesthetic appearance while ensuring structural integrity.
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
Provides a quick, adhesive-free, and durable magnet installation that maintains a screwless decorative appearance, enhancing the usability and aesthetics of control device faceplates.
Implementation Method 1
Magnets may be instead used to secure the faceplate portions together
Implementation Method 2
The first bore portion comprises a resilient tongue and the second bore portion contains an opening and a second attachment member recessed from the openings. The magnet is retained by the magnet retaining pocket by being inserted into the first bore portion to deflect the tongue

AI summary
A magnet retaining pocket defined by a bore having a first bore portion and a second bore portion, wherein the first bore portion comprises a resilient tongue, and wherein the second bore portion contains an opening and a second attachment member recessed from the openings. The magnet is retained by the magnet retaining pocket by being inserted into the first bore portion to deflect the tongue and slid into the second bore portion, such that the first attachment member of the magnet engages the second attachment member of the second bore portion, until the magnet is exposed through the opening.
