Display Mounting Cam Assembly for Blind Panel Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for mounting electronic equipment items, such as display devices, in instrument panels are complex and costly due to the need for precise positioning and separate electrical and mechanical connections, which are difficult to manage without damaging connectors or ensuring safety and reliability.
Innovation Solution
A mechanical mounting system where each lateral face of the electronic equipment item features a cam with a quarter-circle form and triangular point, allowing for guided rotation and secure positioning within the frame, enabling simultaneous mechanical and electrical connections without requiring extensive cable lengths or complex positioning tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical guiding means with precise positioning tolerances are used to ensure correct pre-positioning of the equipment item, then the electrical and mechanical connections are simultaneously assured, but the system becomes expensive and complex
Solution Approach 1:
The patent combines mechanical guidance and electrical connection functions into a single integrated connector assembly. The connector includes both mechanical engagement elements and electrical contacts that are mounted together as one unit, eliminating the need for separate mechanical guiding means and achieving simultaneous mechanical and electrical connection without requiring complex positioning tolerances
Solution Approach 2:
The connector is designed to perform multiple functions simultaneously: it provides mechanical support, electrical connection, and positioning guidance all in one component. This multi-functional design replaces the need for separate mechanical guiding means and simplifies the overall mounting system while maintaining connection reliability
2Ease of operation
If the electrical connection and mechanical connection are performed separately, then the mounting process becomes more manageable, but a significant strand length is required and it becomes difficult to check the placement of the strand
Solution Approach 1:
The patent merges the electrical connector and mechanical mounting functions into a single integrated assembly. The connector includes both electrical contacts and mechanical engagement elements that are mounted together in one operation, eliminating the need for separate mounting steps and allowing the use of shorter cable strands while maintaining ease of operation
Solution Approach 2:
The connector is pre-assembled with both electrical and mechanical components in the correct configuration before installation. This preliminary assembly ensures proper alignment and positioning, making the mounting process simpler and reducing the required strand length since no complex field adjustments are needed
3Productivity
If the equipment item is mounted blind in the instrument panel, then the mounting process is simplified, but it becomes difficult to perfectly check the placement of the strand behind the equipment item
Solution Approach 1:
The integrated connector design is self-aligning and self-verifying. The mechanical and electrical components are configured to automatically ensure correct positioning during installation, eliminating the need for complex verification procedures even when mounting blind. The design itself provides the verification mechanism through its inherent geometric and electrical contact requirements

AI summary
Mechanical mounting devices for an electronic housing in a frame are provided, the electronic housing comprising a front face, a rear face, a bottom and two lateral faces, the frame comprising an opening. The electronic housing comprises, on each lateral face, a mechanical cam having a quarter-circle form, one of the two ends of the cam being terminated by a triangular point the end bearing the point being disposed close to the bottom, the second end being disposed along the front face. The bottom of the frame comprises a bottom abutment parallel to the front face. The opening of the frame comprises two guiding pins disposed on either side of the uprights of the opening and arranged such that each cam can be displaced in rotation on the pin which corresponds to it during the phase of mounting of the electronic housing in the frame.
