Monitor Back Cover Anti-Theft Reinforcement Ribs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-theft designs for display monitors are time-consuming and costly due to the manual positioning of reinforcement metal sheets during the hot melting process, and can result in loose sheets damaging internal components or making noise.
Innovation Solution
An integrally formed reinforcement rib structure on the back cover, comprising a first and second ring-shaped rib with longitudinal and transverse ribs, provides structural strength to the anti-theft hole without the need for manual positioning of reinforcement metal sheets, reducing manufacturing costs and preventing damage to internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a reinforcement metal sheet is manually positioned and fixed on the back cover during hot melting process, then the structural strength of the anti-theft hole is improved, but the manufacturing time and cost are greatly increased
Solution Approach 1:
The reinforcement rib structure is integrally formed with the back cover as a single piece through injection molding, merging the reinforcement function directly into the back cover structure. This eliminates the need for separate reinforcement metal sheets and manual positioning operations, thereby reducing manufacturing time while maintaining structural strength.
Solution Approach 2:
The reinforcement structure is divided into multiple ribs (first ring-shaped rib, second ring-shaped rib, longitudinal ribs, and transverse ribs) that are integrally formed with the back cover. This segmentation allows the reinforcement to be distributed across multiple strategic locations around the anti-theft hole, providing sufficient structural strength without requiring additional manual reinforcement components.
2Strength
If a reinforcement metal sheet is fixed on the back cover, then the structural strength of the anti-theft hole is improved, but the loose sheet may hit internal components causing damage or noise
Solution Approach 1:
By merging the reinforcement structure with the back cover as an integral component, the invention eliminates the possibility of loose reinforcement sheets detaching and damaging internal components. The reinforcement ribs remain permanently fixed as part of the back cover structure, preventing any harmful effects from loose materials.
Solution Approach 2:
The back cover itself provides the reinforcement function through its integrated rib structure, eliminating the need for separate reinforcement metal sheets. The back cover structure serves dual purposes: as the outer cover and as the reinforcement element, thereby preventing the harmful effects associated with loose reinforcement materials.

AI summary
A back cover with an anti-theft function is for containing a monitor body cooperatively with a front frame and includes a reinforcement rib structure and a cover body having an anti-theft hole. The reinforcement rib structure is formed on an inner side of the cover body facing the monitor body and includes a first ring-shaped rib disposed around the anti-theft hole, a second ring-shaped rib disposed around the first ring-shaped rib, two longitudinal ribs, and four transverse ribs. The two longitudinal ribs extend respectively from a top end and a bottom end of the first ring-shaped rib to the second ring-shaped rib along a center longitudinal axis of the first ring-shaped rib. The four transverse ribs extend respectively from two sides of the first ring-shaped rib to the second ring-shaped rib along a center transverse axis of the first ring-shaped rib in a symmetrical arrangement.
