Laptop Bottom Cover Locking Structure Against Tampering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable information handling systems lack effective security measures to prevent intrusion and tampering, allowing unauthorized access and data exfiltration, as conventional cable locks do not secure the system's internal components.
Innovation Solution
A portable information handling system locking system featuring a D-Cover locking component with a steel plate and cable lock attachment, which prevents removal of the D-Cover and ensures tamper resistance and evidence of unauthorized access, by requiring the lock side to be released first for component access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cable locks are used to secure portable information handling systems, then the system is protected from theft, but the system remains vulnerable to intrusion and unauthorized access to internal components
Solution Approach 1:
The locking system is divided into multiple functional components: a cable lock for external security, a D-Cover locking component with steel plate for internal component security, and aligned apertures in top and bottom covers for integrated locking. This segmentation allows each component to address specific security vulnerabilities independently.
Solution Approach 2:
The D-Cover locking component with steel plate is nested within the base chassis structure, with the steel plate positioned to prevent removal of the D-Cover. The cable lock attaches to this nested structure, creating layers of security where the internal locking mechanism is contained within the overall chassis assembly.
2Ease of operation
If the bottom cover is made removable for component access, then maintenance and upgrades are easier, but security against tampering and data exfiltration is compromised
Solution Approach 1:
The D-Cover locking component with steel plate is pre-installed in the base chassis before the D-Cover is attached. The steel plate extends through the D-Cover, and the locking aperture is pre-aligned with the top cover aperture, so that when the lock is engaged, it immediately prevents D-Cover removal without requiring additional security steps during component access operations.
3Reliability
If a comprehensive locking system with multiple components is implemented, then security against intrusion and tampering is improved, but device complexity increases
Solution Approach 1:
The D-Cover locking component combines multiple functions into a single integrated structure: the steel plate provides structural reinforcement and prevents D-Cover removal, while simultaneously defining the locking aperture that aligns with the top cover. This merging reduces the number of separate parts compared to having independent locking mechanisms for each cover.
Solution Approach 2:
The D-Cover locking component serves multiple security functions: it reinforces the base chassis structure with the steel plate, prevents removal of the D-Cover, and provides the locking aperture for cable attachment. This multi-functionality reduces overall system complexity by eliminating the need for separate components for each function.
