Security Strip for Thin Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing thinness of modern mobile devices, such as notebooks and tablets, makes it impractical to incorporate standard security slots, as the standard lock body is thicker than the devices themselves, rendering existing security solutions ineffective for securing these devices against theft.
Innovation Solution
A security strip or stick-on component is designed to attach to the underside of mobile devices, featuring a thin, elongated body with screw holes and a trapezoidal security slot that can accommodate both standard and thinner locking elements, along with a yoke-shaped security plate that engages the power plug to prevent removal, ensuring secure attachment and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard security slot is incorporated into a mobile device, then theft prevention capability is improved, but the device thickness increases beyond acceptable limits
Solution Approach 1:
The security system is divided into separate components: a thin security slot component that can be attached to the device surface, and a separate locking element. This segmentation allows the security function to be added without increasing the device thickness, as the slot component is designed to be attachable to the external surface rather than embedded within the device body.
Solution Approach 2:
The security slot is designed to extend in a direction substantially perpendicular to the surface of the mobile device, utilizing the third dimension (depth) rather than increasing the device thickness in the primary dimension. The slot has a depth that accommodates the locking element while maintaining a minimal profile on the device surface.
2Reliability
If a security slot is added to thin mobile devices, then security functionality is improved, but the device complexity increases
Solution Approach 1:
The security slot component is designed with universal attachment capabilities that can accommodate different mobile device types and configurations. The slot can be attached to various surfaces and works with standard locking elements, reducing the need for device-specific security implementations and simplifying the overall system architecture.
Solution Approach 2:
The security slot component acts as an intermediary element between the mobile device surface and the locking mechanism. This intermediate component simplifies the integration process by providing a standardized interface that decouples the device structure from the security mechanism, reducing overall system complexity.
3Reliability
If the security slot depth is increased to accommodate standard locks, then locking security is improved, but the slot protrusion increases affecting device profile
Solution Approach 1:
The locking element is designed to nest within the security slot, with the T-shaped bar fitting into the slot's cavity. The slot depth is optimized to accommodate the locking element while minimizing external protrusion, creating a nested configuration that provides secure locking without significantly increasing the overall profile.
Solution Approach 2:
The security slot features localized thickening or reinforcement at specific regions to provide adequate depth for secure locking while maintaining a thin overall profile. The slot wall thickness and depth are optimized locally at the slot position rather than increasing the entire component thickness uniformly.

AI summary
A security strip defining a security slot and attachable to a mobile electronic device has a strip body shaped as a flat and thin, strip-shaped component with a length, a width and a thickness dimension, wherein the length of the strip body is at least ten times times the thickness dimension of the strip body. Screw holes enable screwing the strip body to an underside of the mobile electronic device. A security slot body protrudes from the strip body and has a thickened portion thicker than the thickness dimension of the strip body and defining therein a security slot in which a locking element of a locking device is receivable, the security slot body extending along the one of the side walls of the mobile device. The security strip includes at least one cutout that enables the security strip to extend generally in line of one of the front and rear legs of the mobile device so that at least one of the front or rear legs is at least partially locatable in the at least one cutout in the strip.
