Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of reliable and mobile solutions for providing secured access to unsecured networks for laptop computers, particularly in public environments, and for securing data storage peripherals during data transfers, which can lead to risks of intrusion and infection by malicious software.
Innovation Solution
A portable communication peripheral with embedded security features, including a firewall, autonomous DNS management, and geolocation capabilities, that connects via USB or Wi-Fi, allowing secure access to data networks and preventing unauthorized access, while being compact enough to fit in a pocket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a portable peripheral with embedded security unit is used to secure access to data networks, then security reliability is improved, but device complexity increases
Solution Approach 1:
The security unit is embedded within the portable peripheral housing, creating a nested structure where the security functionality is contained within the larger peripheral device. This allows the security unit to be portable and removable while maintaining its protective function, resolving the contradiction by integrating security into a compact form factor that doesn't significantly increase overall device complexity
Solution Approach 2:
The portable peripheral acts as an intermediary device between the portable terminal and the data network. It establishes itself as an intermediate node in the communication path, filtering and securing traffic before it reaches the terminal. This mediator approach provides enterprise-level security without requiring modification of the terminal itself, maintaining simplicity while improving reliability
2Ease of operation
If the peripheral is made portable and compact to fit in a pocket, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The peripheral housing is designed to serve multiple functions: it provides structural containment, defines the portable form factor for pocket carrying, and interfaces with both the terminal and network. By making the housing itself the universal container for all security and communication components, the design achieves portability without requiring multiple separate components, thus managing manufacturing precision requirements
3Reliability
If the security unit includes autonomous DNS management and firewall capabilities, then security reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple security functions (firewall, autonomous DNS management, packet filtering) into a single integrated security unit. Rather than implementing these as separate distributed components, they are merged into one cohesive embedded system within the portable peripheral. This consolidation provides comprehensive security while managing complexity through unified architecture rather than distributed complexity
