Display Assembly Spring Clips for Bezel-Free Automated Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for coupling displays in portable information handling systems face challenges in achieving robust assembly without using screws or adhesives, which disrupt automated manufacturing and fail to provide sufficient shock and vibration resistance.
Innovation Solution
The use of spring clips extending from the display assembly engage with housing side walls to provide resilient tension, securing the display in place without additional securing mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to secure the display panel to the housing, then the display panel is held firmly in place, but a bezel is required to cover the gap around the display panel, increasing housing perimeter size and detracting from aesthetic appearance
Solution Approach 1:
The invention extracts the fastening function from the perimeter area by using spring clips that extend from the display panel's side surfaces to engage with recesses in the housing. This eliminates the need for a bezel to cover screw holes or adhesive gaps, allowing the display panel to extend to the housing perimeter without compromising structural integrity or aesthetic appearance.
Solution Approach 2:
The spring clips extend laterally from the display panel's side surfaces rather than securing it from the front or back. This dimensional approach allows the display panel to reach the housing perimeter while the clips provide securing force from the side, eliminating the need for a perimeter bezel.
2Shape
If adhesive is used to bond the display panel in place, then a zero bezel design is achieved with minimal housing perimeter, but the display panel is not serviceable after installation and may not withstand shock and vibration requirements
Solution Approach 1:
The spring clips provide dynamic, adjustable securing force that can accommodate shock and vibration conditions. Unlike adhesive, which is static and irreversible, the spring clips can be compressed and released, allowing for serviceability while maintaining a secure bond that withstands mechanical stress.
Solution Approach 2:
The spring clips are self-contained fastening elements that integrate the securing function directly into the display panel assembly. They provide both the bonding force and the serviceability feature, eliminating the need for separate adhesive application and enabling future maintenance or replacement.
3Reliability
If screws or adhesives are used to secure the display panel, then sufficient coupling strength is achieved to withstand shock and vibration, but automated manufacturing processes are disrupted due to difficulty in robotic manipulation
Solution Approach 1:
The spring clips are segmented into discrete, modular fastening elements that can be independently positioned and engaged. This segmentation allows for automated robotic manipulation, as each clip can be individually secured by a robotic arm following a programmed path, unlike continuous adhesive application or precision screw fastening.
Solution Approach 2:
The invention replaces complex mechanical fastening systems (screws requiring precision alignment and torque control) and chemical bonding systems (adhesive requiring precise application and curing time) with a simpler spring clip mechanism that combines elastic deformation and mechanical engagement, which is more suitable for automated robotic assembly.
4Stability of the object's composition
If a bezel is used to cover the gap around the display panel, then the display panel is securely held, but the housing perimeter size increases and aesthetic appearance is compromised
Solution Approach 1:
The invention extracts the positioning function from the perimeter area by using spring clips that extend from the display panel's side surfaces to engage with recesses in the housing. This eliminates the need for a bezel to cover gaps or provide structural support, allowing the display panel to extend to the housing perimeter while maintaining positioning stability.

Function Achieved in This Case
This method simplifies assembly, enhances shock and vibration resistance, and maintains a minimal bezel design, facilitating automated manufacturing and improved aesthetics.
Implementation Method 1
the curved portion pressing against the housing side wall generates spring tension resisted by the spring clip end against the display support side wall

AI summary
A portable information handling system display assembly couples to a portable housing with spring clips that extend out from a support of the display assembly to engage against the portable housing, such as within cavities formed in the housing to align the display assembly with a desired position. In one embodiment, the spring clips extend out from the support and up towards a display panel to compress against a side of the support. In an alternative embodiment, the spring clips extend out from the support and down away from the display panel.
