Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems in computing devices, such as NFC, suffer from issues like interference and eavesdropping due to close proximity of devices, leading to unintended communication and security vulnerabilities.
Innovation Solution
A computing device identification tag-based system that enables/disables wireless communication by moving between retracted and extended orientations, using a wireless antenna and a subsystem to obstruct or enable communication based on the tag's position, preventing interference and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If wireless communication devices are positioned adjacent to each other in racks, then device density and space utilization are improved, but wireless communication interference and security vulnerabilities increase
Solution Approach 1:
The patent applies the dynamics principle by making the identification tag moveable between retracted and extended orientations. When the tag is extended, it actively blocks wireless communication signals from reaching adjacent devices, dynamically creating a communication barrier. This dynamic positioning allows the system to adapt to different operational states (communication needed vs. communication blocked) while maintaining high device density in rack configurations.
2Ease of operation
If wireless communication range is extended to allow management devices to retrieve status information, then communication accessibility is improved, but security against eavesdropping deteriorates
Solution Approach 1:
The patent extracts the wireless communication capability from being continuously available and ties it to the specific physical state of the identification tag. By taking out the communication function and making it conditional on the tag's extended orientation, the system allows communication only when explicitly needed and blocked when the tag is retracted, thus maintaining accessibility when required while preventing eavesdropping by default.
3Productivity
If identification tag is kept extended to enable wireless communication, then communication availability is improved, but device security and interference prevention deteriorate
Solution Approach 1:
The system dynamically adjusts communication availability based on the identification tag's position. The tag can be extended to enable communication with authorized management devices or retracted to block communication and prevent eavesdropping. This dynamic behavior allows the system to optimize productivity when communication is needed while maintaining security when it is not, resolving the contradiction between communication availability and device security.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents unintended wireless communication and eavesdropping by disabling communication when the tag is retracted and enabling it when needed, improving security and reducing interference among closely spaced devices.

AI summary
A computing-device-identification-tag-based wireless communication enablement/disablement system includes a computing device chassis, and a computing device identification tag that is moveably coupled to the computing device chassis such that the computing device identification tag is configured to be moved between a retracted orientation in which the computing device identification tag is housed in the computing device chassis, and an extended orientation in which the computing device identification tag extends from the computing device chassis. A wireless antenna is included on the computing device identification tag. A wireless communication enablement/disablement subsystem is included in the computing device chassis and is configured to disable wireless communications via the wireless antenna when the computing device identification tag is provided in the retracted orientation, and enable wireless communications via the wireless antenna when the computing device identification tag is provided in the extended orientation.
