Solution Overview

Problem

Conventional cellular devices constantly transmit signals, making them detectable by radio transmission detection devices, which poses a security risk, especially for military use, as they cannot receive data without transmitting and lack the control over transmission that radio devices have.

Innovation Solution

A method and system for selectively enabling and disabling radio frequency communications in cellular devices, allowing for controlled transmission and reception of data and voice communications, including disabling RF communications when not in use to avoid detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cellular devices use constant transmission to base stations for handover and full duplex communications, then communication reliability and data transmission capability are improved, but detectability by radio transmission detection devices increases, creating security risks

Engineering Contradiction:

Improvecommunication reliabilityVSAvoiddetectability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies dynamics by making the transmission state changeable - the device can dynamically switch between constant transmission mode (for reliability) and selective transmission mode (for security). The system transitions from a static always-transmitting state to a dynamic state that can adapt transmission behavior based on operational requirements, allowing the device to maintain communication reliability when needed while avoiding detection when security is prioritized.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the transmission parameter from constant/continuous to selective/discontinuous. By modifying the transmission parameter state, the device can alter its detectability characteristic while maintaining communication functionality. This parameter change enables the device to switch between being easily detectable (constant transmission) and hard to detect (selective transmission) based on operational context.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If cellular devices transmit constantly to maintain communications during movement, then handover capability and communication continuity are improved, but the ability to avoid location detection by hostile forces deteriorates

Engineering Contradiction:

Improvecommunication continuityVSAvoidlocation detectability

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies periodic action by replacing constant transmission with intermittent or periodic transmission. Instead of continuously transmitting to maintain handover and communication continuity, the device can transmit periodically or only when necessary, thereby maintaining communication productivity while creating detection gaps that prevent continuous location tracking by hostile forces.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent extracts the constant transmission function from the communication system, separating the essential communication data transmission from the continuous handover signaling. By extracting and eliminating the constant transmission component, the device retains the ability to communicate data while removing the continuous signal that enables location detection.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If cellular devices are used for secure communications, then computing functionality and data processing capability are improved, but the inherent constant transmission makes them vulnerable to radio transmission detection devices

Engineering Contradiction:

Improvecomputing functionalityVSAvoidsecurity vulnerability

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the communication function into separate components: data communication capability (maintained through selective transmission) and location detection signature (eliminated through selective transmission). By segmenting these functions, the device can retain the computing and data communication adaptability of cellular devices while eliminating the constant transmission signature that creates security vulnerabilities.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary control mechanism that mediates between the cellular device's communication functions and its transmission behavior. This intermediary enables the device to selectively enable or disable transmission based on security requirements, allowing the device to maintain computing functionality while controlling its detectability to avoid security vulnerabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)
