Display Retention Bracket for Horizontal Mounting in Vertical Bezel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial control system displays face challenges with horizontal mounting, cable management, force distribution, grounding, and dust gasket compression due to bezel design limitations, leading to potential operational impairments.
Innovation Solution
A display retention bracket (DRB) with display retention components, cable retention components, alignment pins, non-symmetrical tabs, offset columns, and a ground clip is used to securely mount and align displays horizontally within bezels that only support vertical mounting, ensuring proper orientation, cable security, and adequate grounding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is mounted horizontally using screws in the sides of the display housing, then the display can be retained in the horizontal direction, but the bezel design does not support horizontal mounting and only allows vertical mounting
Solution Approach 1:
The mounting system is divided into two independent functions: vertical mounting is handled by the bezel's existing vertical mounting structure, while horizontal retention is achieved through a separate bracket mechanism with retention components that engage with holes in the display housing. This segmentation allows each function to be optimized independently.
Solution Approach 2:
A bracket serves as an intermediary component between the display housing and the bezel. The bracket includes retention components that horizontally secure the display while the bracket itself is vertically mounted in the bezel. This intermediary enables horizontal retention without requiring the bezel to directly support horizontal mounting.
2Ease of operation
If cable connectors are allowed to be pulled out with less than 15 Newtons of force, then cable connection is easy to establish, but the cable connector may be disengaged from the socket under normal operation conditions
Solution Approach 1:
The cable retention component is pre-positioned within the bracket to engage with the cable connector before any pulling force is applied during operation. This preliminary engagement ensures that the cable connector is secured against the socket from the outset, preventing accidental disengagement while maintaining ease of connection.
3Device complexity
If the display is inserted into the bezel housing without horizontal mounting capability, then the bezel design is simplified, but the display does not have a conductive ground path with the bezel
Solution Approach 1:
The bracket acts as an intermediary that provides the conductive ground path between the display and the bezel. The bracket includes a ground clip that extends from the bracket to contact both the display housing and the bezel, creating a reliable electrical grounding path without requiring the display to be horizontally mounted in the bezel.
4Device complexity
If the dust gasket is not positioned below the display, then the display assembly is simpler, but the dust gasket cannot be compressed to perform properly
Solution Approach 1:
The bracket is designed with offset columns that preliminarily position and compress the dust gasket below the display before the display is fully assembled into the bezel. This preliminary compression ensures the dust gasket is properly positioned and functional, while the overall assembly remains relatively simple.

AI summary
The disclosed subject matter comprises a display retention bracket (DRB) that can be attached to, and can retain and horizontally mount, a display using display retention components, without using fasteners, for insertion of the display in a bezel that does not support horizontal mounting; and includes: a cable retention component that enables the cable to withstand a specified pull-out force to maintain connection of the cable to the display; a cable guide to maintain cable wires in a desired position in relation to other components; alignment pins to align the DRB and display with a bezel housing; non-symmetrical tabs to ensure the display is oriented correctly; offset columns that desirably offset loads on the display when an adapter plate is applied onto the DRB and display, and fastened to the bezel to secure the display; and a ground clip to extend the ground path from the bezel to the display.
