Magnetic Nameplate Locking Assembly for Secure Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nameplates lack a secure and removable attachment mechanism that prevents unintentional removal or displacement due to casual contact, wind, or vibrations, while allowing for easy updates and replacements.
Innovation Solution
A nameplate design featuring a locking member that moves between locking and non-locking conditions, utilizing a metallic region and magnetic member to secure the nameplate insert within a holder, with a resilient member for enhanced stability and ease of removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable attachment mechanism is used to allow easy replacement of nameplate inserts, then the ease of operation is improved, but the reliability is worsened due to potential unintentional removal or displacement
Solution Approach 1:
The locking member is designed to be movable between a first condition (engaging the notch to secure the insert) and a second condition (disengaged to permit removal). This dynamic mechanism allows the system to automatically transition between secure and removable states based on operational needs, resolving the contradiction between ease of replacement and security against unintentional removal
Solution Approach 2:
The resilient member automatically biases the locking member into the engaged position, providing self-locking functionality without requiring additional fastening operations. The system self-regulates to maintain secure attachment while allowing intentional removal when needed
2Reliability
If a locking mechanism is added to secure the nameplate insert, then the reliability is improved, but the device complexity is worsened
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: a locking member with a portion that engages the notch, a resilient member providing biasing force, and a magnetic member for actuation. This segmentation allows each component to perform its specific function with simple geometry, reducing overall complexity while maintaining reliability
Solution Approach 2:
The magnetic member acts as an intermediary that enables remote actuation of the locking mechanism without requiring direct mechanical intervention. By using magnetic field interaction with the metallic region, the system achieves secure locking and release functionality with minimal mechanical complexity
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 design provides secure retention of the nameplate insert against movement while allowing for easy replacement, effectively resisting casual contact, wind, and vibrations, ensuring the nameplate remains firmly in place until intentionally removed.
Implementation Method 1
a magnetic member configured to move the locking member between the first and second conditions via the metallic region of the locking member
Implementation Method 2
a resilient member configured for receipt in the cavity of nameplate holder. The resilient member may be supported on the locking member. In the first condition, the resilient member may be in a non-compressed condition in which the portion of the locking member protrudes into the longitudinal channel of the nameplate holder

AI summary
A nameplate includes a nameplate holder, a nameplate insert, and a locking member. The nameplate holder defines a longitudinal channel. The nameplate insert defines a notch and is configured for movable receipt within the longitudinal channel of the nameplate holder. The locking member is movable within the nameplate holder between a first condition and a second condition. In the first condition, a portion of the locking member extends within the notch of the nameplate insert to resist longitudinal movement of the nameplate insert relative to the nameplate holder. In the second condition, the portion of the locking member is disposed outside of the notch of the nameplate insert.
