Electronics Module Mounting System With Guide Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronics module mounting systems are cumbersome to install, prone to damage during alignment, and lack securement in harsh conditions, with complex backplane connectors susceptible to interference and dislodgment, and often require multiple steps for secure installation and ground connection, while also lacking convenient accessory mounting options.
Innovation Solution
A modular mounting system featuring a baseplate with channels and mounting legs, module bases with tabs and connectors, and a method of installation that progressively secures modules along X, Y, and Z axes, ensuring precise alignment and secure fastening, while allowing for easy accessory attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual positioning of the module in space with six degrees of freedom is used, then the module can be installed in its operative position, but the alignment process is time-consuming and the connectors are susceptible to damage during misalignment
Solution Approach 1:
The guide structure performs preliminary alignment actions before the actual connector mating. The guide structure includes alignment features that automatically position the module correctly as it is inserted, preventing misalignment damage to the connectors while simplifying the installation operation
Solution Approach 2:
The guide structure acts as an intermediary between the module and the mounting surface. It provides a controlled interface that guides the module into proper alignment before the connectors make final contact, protecting the connectors from damage during the alignment process
2Adaptability or versatility
If complex backplane connectors with multiple pins and contacts are used, then high-frequency and complex data communications protocols can be implemented, but the connectors are more susceptible to damage during module installation if not properly aligned
Solution Approach 1:
The guide structure performs preliminary alignment of the complex multi-pin connectors before mating, ensuring all pins and contacts are properly positioned. This preliminary guidance action protects the complex connector structures from damage while enabling the high-frequency data communication capabilities
3Ease of operation
If the module mounting system does not provide adequate securement, then the installation process is simpler, but the module can become dislodged from its installed operative position under vibrations and physical forces
Solution Approach 1:
The mounting system is segmented into multiple functional components: the guide structure for alignment, the mounting base for securement, and fastening mechanisms. This segmentation allows the guide structure to handle alignment simply while the dedicated mounting components provide stable securement against vibrations and forces
4Reliability
If multiple steps are required to secure the module and establish ground connection, then the connection can be more reliable, but the installation process becomes more time-consuming
Solution Approach 1:
The mounting base merges multiple functions into a single component: mechanical securement and electrical ground connection are integrated into one structure. This allows the module to be secured and grounded simultaneously in a single installation action, maintaining reliable connections while reducing installation time

AI summary
An electronics module mounting system includes a baseplate with a main wall, opposite left and right ends spaced apart from each other along an X axis, and opposite first and second spaced-apart edges extending between the left and right ends. The first and second edges are spaced apart along a Y axis. The baseplate includes a first channel that projects outwardly from the main wall and includes a mounting leg that projects outwardly from the main wall and that forms a mounting recess. A module mounting base is connected to the baseplate and includes a mounting tab located in the mounting recess. The mounting base includes a front face to receive and retain an electronics module and a rear face located opposite the front face. A channel recess is located in the rear face and extends between opposite left and right edges of the mounting base. The channel of the baseplate is located in the channel recess. The mounting base includes first and second electrical connectors that are aligned with each other and aligned with the channel recess. A fastener extends through the mounting base at a location aligned with the channel recess such that the fastener is engaged with the channel of the baseplate.
