Backplane Latch Assembly for Vibration-Resistant Module Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote terminal units lack expandability and are prone to unintentional disengagement due to environmental vibration, as the modules and backplane are not robust enough to withstand such conditions.
Innovation Solution
A backplane assembly kit with a latch component that pivotally engages with slots on a detachable assembly, utilizing a resilient component to maintain a locking position and prevent detachment, and an operating component to unlock the latch for detachment, allowing modules to be assembled laterally for expandability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional mounting structure is used, then the device structure is simple, but the module easily disengages due to environmental vibrations
Solution Approach 1:
The latch component is designed to be movable between a first position (engaged with the slot) and a second position (disengaged from the slot). This dynamic structure allows the mounting system to transition from a simple static connection to a secure dynamic locking mechanism, resolving the contradiction between structural simplicity and engagement stability under vibration.
Solution Approach 2:
The latch component acts as an intermediary element between the module and the backplane. It mediates the connection by engaging with the slot on the module, providing an additional securing mechanism that prevents disengagement due to vibrations while maintaining the simplicity of the overall mounting structure.
2Reliability
If the module is firmly fixed to the backplane, then vibration resistance is improved, but the expandability of the device is reduced
Solution Approach 1:
The dynamic latch mechanism allows the system to switch between a secured state (latch engaged) for vibration resistance and an accessible state (latch disengaged) for expandability. This resolves the contradiction by providing both firm fixation when needed and easy removal when expansion is required.
Solution Approach 2:
The latch component is pre-positioned to engage with the slot automatically when the module is mounted, providing immediate vibration resistance. When expansion is needed, the latch can be easily disengaged, allowing the module to be removed or replaced without complex disassembly procedures.
3Adaptability or versatility
If a detachable assembly structure is used, then the expandability is improved, but the assembly becomes prone to disengagement under vibration
Solution Approach 1:
The latch component serves as an intermediary that enhances the stability of the detachable assembly structure. It provides a secure engagement point that prevents accidental disengagement under vibration while preserving the inherent expandability of the detachable design.
Solution Approach 2:
The detachable assembly is segmented into the module with the slot and the backplane with the latch component. This segmentation allows the module to be easily attached and detached while the latch provides continuous securing force during operation, resolving the contradiction between detachability and vibration resistance.

AI summary
An electronic device is provided and includes a backplane assembly, a detachable assembly and a locking assembly. The detachable assembly is detachably assembled with the backplane assembly. A slot is formed on the detachable assembly. The locking assembly is disposed between the backplane assembly and the detachable assembly for locking the detachable assembly on the backplane assembly. The locking assembly includes a latch component pivotally disposed on the backplane assembly. An end of the latch component is configured to stretch into the detachable assembly through the slot. The end of the latch component engages with the slot for restraining the detachable assembly from being detached from the backplane assembly when the latch component is located at a locking position. Besides, a related backplane assembly kit and a related detachable assembly kit are also provided.
