Monitor Enclosure Stiffener Wings for Rigidity and Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumer demand for thinner and lighter monitor devices with high-quality structural support is challenging due to conflicting requirements of rigidity and reduced weight, as existing enclosures often increase bulkiness to achieve support.
Innovation Solution
The enclosure assembly incorporates stiffener wings and deck insert members to provide structural support while minimizing weight and profile, using materials like metal and plastic to create a robust yet lightweight chassis with ribbed structures and optimized mounting surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional and thicker support structures are used to provide rigid structural support for large touchscreen displays, then the structural rigidity and high quality feel are improved, but the weight and bulkiness of the monitor device increase
Solution Approach 1:
The support structure is divided into multiple discrete stiffener components (first stiffener, second stiffener, third stiffener, fourth stiffener) positioned at strategic locations around the display perimeter. Each stiffener is a separate element that can be independently optimized and assembled, providing distributed structural support rather than relying on a single bulky support structure.
Solution Approach 2:
The stiffeners extend in multiple directions (first direction, second direction perpendicular to first, third direction, fourth direction perpendicular to third) to provide structural support in two-dimensional space. This multi-directional arrangement creates a rigid framework that resists bending and twisting forces from various directions without requiring increased thickness in any single dimension.
2Strength
If additional and thicker support structures are used to provide rigid structural support for large touchscreen displays, then the structural rigidity and high quality feel are improved, but the bulkiness of the monitor device increases
Solution Approach 1:
The support structure is divided into multiple discrete stiffener components (first stiffener, second stiffener, third stiffener, fourth stiffener) positioned at strategic locations around the display perimeter. Each stiffener is a separate element that can be independently optimized and assembled, providing distributed structural support rather than relying on a single bulky support structure.
Solution Approach 2:
Stiffeners are placed at specific locations where structural support is most needed (corners and edges of the display perimeter) rather than uniformly distributing material throughout the entire enclosure. This localized reinforcement provides maximum structural benefit with minimum material usage, avoiding unnecessary bulk in areas where support is not critical.
3Weight of moving object
If a lightweight enclosure design is used to reduce device weight and bulk, then the weight and profile are improved, but the structural support and rigidity are insufficient
Solution Approach 1:
The stiffeners extend in multiple directions (first direction, second direction perpendicular to first, third direction, fourth direction perpendicular to third) to provide structural support in two-dimensional space. This multi-directional arrangement creates a rigid framework that resists bending and twisting forces from various directions without requiring increased thickness in any single dimension.
Solution Approach 2:
The enclosure utilizes different materials with complementary properties: the enclosure cover and back are formed from lightweight materials (metal or plastic), while the stiffeners are made from rigid materials providing structural reinforcement. This composite approach combines the advantages of lightweight construction with targeted structural support.

AI summary
An enclosure assembly of a monitor device includes an enclosure cover having a cover wall extending substantially in a first plane between a plurality of sides, wherein the cover wall includes an interior surface and an opposing exterior surface. The enclosure assembly includes a first stiffener wing and a second stiffener wing each having one or more mounting portions spaced apart from one or more stiffener portions to define one or more wing body ribs, each mounting portion including a mounting surface opposing a corresponding portion of the interior surface of the cover wall. The first stiffener wing includes a first wing body that extends toward a first side of the enclosure cover, and the second stiffener wing includes a second wing body that extends to a second side of the enclosure cover. Additionally, a display and/or a base assembly may be mounted to the enclosure assembly.
