Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile devices are transported to a shielded analysis room for forensic analysis, then data integrity is protected from remote manipulation, but analysis time is increased due to transportation requirements
Solution Approach 1:
The patent employs a flexible shielded container made of conductive material that can be collapsed for portability and expanded to create a Faraday cage environment at the crime scene, eliminating transportation time while maintaining data integrity through electromagnetic shielding
Solution Approach 2:
The flexible shielded container acts as an intermediary structure that can be deployed between the crime scene and the analyst, providing immediate electromagnetic isolation without requiring permanent shielded facilities or transportation of devices
2Productivity
If mobile devices are analyzed at the crime scene using a portable shielded container, then analysis time is reduced by eliminating transportation, but the complexity of deploying and setting up the shielded environment increases
Solution Approach 1:
The shielded container transitions from a collapsed portable state to an expanded operational state, allowing easy deployment and setup at the crime scene while maintaining complex shielding functionality through a simple collapsible structure
Solution Approach 2:
The flexible conductive material enables the shielded container to be easily collapsed for transport and quickly expanded at the scene, reducing setup complexity while maintaining the electromagnetic shielding effect through the conductive material properties
3Reliability
If conductive materials are used in the shielded container to block electromagnetic radiation, then remote switching off and data modification are prevented, but the flexibility and portability of the container may be reduced
Solution Approach 1:
The patent uses flexible conductive materials such as conductive fabric or coated materials that maintain electromagnetic shielding properties while allowing the container to be collapsed and easily transported, balancing protection capability with portability
Solution Approach 2:
The shielded container incorporates composite materials combining conductive properties with flexible characteristics, such as conductive fabric or polymer-coated conductive materials, achieving both electromagnetic radiation blocking and flexibility for portability
