Modular Locking Strip for Digital Device Chassis Security Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital device securing solutions are inflexible, requiring users to purchase new chassis when security needs change, leading to high costs for manufacturers due to the need for a range of chassis types to accommodate varying user requirements.
Innovation Solution
A modular locking strip that can be assembled on existing chassis, featuring assembly means, retaining means, and a locking unit with a movable locking lug, allowing for adjustable security levels without replacing the chassis, and compatibility with standard locking slots like Kensington™.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional key and lock system is used to secure the digital device in the chassis, then the security level is improved, but the device complexity and cost increase due to needing multiple chassis types for different security needs
Solution Approach 1:
The locking system is segmented into a reusable locking strip component that can be attached to and removed from the chassis. This allows the security mechanism to be separated from the base chassis structure, enabling a single chassis design to support multiple security levels by simply adding or removing the locking strip rather than manufacturing different chassis types.
Solution Approach 2:
The locking strip serves multiple functions: it provides the locking mechanism, houses the retaining means for the digital device, and offers assembly means for attachment to the chassis. This multi-functional design consolidates what would otherwise require separate components, reducing overall system complexity while maintaining security functionality.
2Adaptability or versatility
If multiple types of chassis are manufactured to accommodate different security requirements, then the adaptability to user needs is improved, but the manufacturing cost and complexity for the manufacturer increase
Solution Approach 1:
The system transitions from a static chassis design to a dynamic configuration where the security level can be changed by attaching or removing the locking strip. This dynamic approach allows the same chassis to adapt to different security requirements without requiring multiple chassis variants, thereby reducing manufacturing costs and complexity.
Solution Approach 2:
The security parameter of the system is made adjustable through the addition or removal of the locking strip, rather than requiring changes to the fundamental chassis structure. This parameter change approach allows flexible adaptation to different security needs while maintaining a standardized chassis design for mass production.
3Ease of manufacture
If a fixed chassis design is used, then the manufacturing cost is reduced, but the adaptability to changing user security needs deteriorates
Solution Approach 1:
By segmenting the locking mechanism into a separate, attachable locking strip component, the system enables a fixed, standardized chassis design to provide variable security levels. Users can adapt the fixed chassis to changing needs by adding or removing the locking strip, combining manufacturing efficiency with flexibility.
4Reliability
If a locking strip is added to enhance security, then the security level is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism, retaining means, and assembly means are merged into a single integrated locking strip component. This consolidation reduces the number of separate parts and interfaces that would otherwise be required, thereby enhancing security without proportionally increasing system complexity.
Solution Approach 2:
The locking strip is designed as a multi-functional component that combines the locking mechanism, device retaining features, and chassis attachment means. This multi-functionality reduces the need for additional separate components, thereby improving security while minimizing the increase in overall system complexity.
