Solution Overview

Problem

Existing encrypted radio connections face challenges in quick and lossless switching from transmission to reception mode during a transmitter break-in, leading to potential data loss, which requires additional functions and connections, increasing costs and complexity.

Innovation Solution

The system automatically overrides the transmission instruction by issuing a break instruction, allowing the radio to switch to reception mode without additional functions or connections, and temporarily stores received data to prevent loss, with the encryption device switching to decryption mode after connection termination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the radio automatically switches to reception mode upon receiving a transmitter break-in signal, then the switching speed is improved, but data loss occurs because the encryption device cannot decrypt the received information

Engineering Contradiction:
Improveswitching speedVSAvoiddata loss
Core Design Contradiction:
SpeedVSLoss of information

Solution Approach 1:

The patent applies preliminary action by having the radio switch to reception mode immediately upon detecting a break-in signal, before the encryption device is ready to decrypt. The received signals are temporarily stored in a buffer, and the encryption device is instructed to switch to reception mode subsequently. This resolves the contradiction by prioritizing rapid switching while preserving data through temporary storage and coordinated mode switching of the encryption device.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the transmission instruction is canceled immediately after transmitter break-in, then data integrity is improved, but additional functions and connections are required in the encryption device

Engineering Contradiction:
Improvedata integrityVSAvoidencryption device complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the break-in handling functionality into the existing radio and encryption device architecture. The radio detects break-in signals and controls the switching to reception mode, while the encryption device receives control signals to switch modes. This integration achieves data integrity without requiring separate additional functions or connections, as the existing components are coordinated through control signals.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If the radio waits for the encryption device to switch to reception mode before receiving data, then data integrity is maintained, but the switching time increases causing potential loss of important message content

Engineering Contradiction:
Improvedata integrityVSAvoidswitching time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements feedback by having the radio send a control signal to the encryption device to switch to reception mode after detecting a break-in signal. The encryption device responds by switching modes and processing the stored received data. This feedback mechanism coordinates the switching actions, ensuring data integrity is maintained through proper synchronization while minimizing delays through efficient signal exchange.

AI summary

The method involves identifying a transmission instruction according to a user demand, which is relayed to a radio device (1) by an encoding device (2). Data generated according to the user demand is emitted and encoded by the encoding device through the radio device. A radio signal is received with the coded data directed to the transmitting radio device. Independent claims are included for the following: (1) a system for wireless transmission of encoded data; and (2) a radio device for receiving a transmission instruction according to user demand.
