Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If static radio identifiers are used for communication, then devices can be easily detected and tracked by unauthorized parties, but communication simplicity and ease of operation are maintained
Solution Approach 1:
The patent implements dynamic radio identifiers that change over time according to pseudorandom sequences, transforming the static identifier system into a dynamic one. This allows the device to maintain communication functionality while preventing unauthorized tracking, as the identifiers evolve predictably for authorized parties but appear random to unauthorized observers.
Solution Approach 2:
The patent changes the temporal parameter of radio identifiers by introducing time-varying pseudorandom sequences. The identifiers are updated at different time intervals, transforming a static parameter into a dynamic one that provides security while maintaining communication ease through synchronized updates between transmitting and receiving devices.
2Object-affected harmful factors
If dynamic pseudorandom radio identifiers are transmitted, then unauthorized tracking becomes difficult, but device complexity increases due to sequence management
Solution Approach 1:
The patent implements self-service through autonomous generation of pseudorandom identifier sequences at both transmitting and receiving devices. Each device independently generates and synchronizes sequences without requiring complex centralized management, reducing overall system complexity while maintaining security through self-synchronized dynamic identifiers.
Solution Approach 2:
The patent employs periodic updates of radio identifiers according to predetermined pseudorandom sequences with specific update intervals. This periodic action simplifies sequence management by establishing regular update cycles that both transmitting and receiving devices can synchronize to, reducing complexity compared to aperiodic or continuously varying identifiers.
3Object-affected harmful factors
If transmission power and frequency are varied dynamically, then transmitter position becomes harder to detect, but energy consumption increases
Solution Approach 1:
The patent implements periodic variation of transmission power and frequency according to predetermined patterns synchronized with identifier updates. This periodic action allows the system to consume energy at regular intervals rather than continuously, reducing overall energy consumption while maintaining the obscuring effect on transmitter position detection through predictable power and frequency changes.
Solution Approach 2:
The patent applies preliminary anti-action by pre-planning transmission power and frequency variations to counteract potential detection attempts. The predetermined variation patterns are designed in advance to obscure transmitter characteristics, allowing the system to proactively prevent detection rather than react to it, optimizing energy usage by avoiding unnecessary continuous adjustments.

AI summary
Systems, devices and methods for concealing radio communications and the spatial position of radio transmitters involved therein include the use of electrotechnical signal variation and dynamic, pseudo-random radio identifier. Transmitted radio signals contain radio identifiers identifying the transmitting mobile radio device. Each radio identifier is dynamically selected for each radio signal from a sequence of radio identifiers selected from a set of predefined pseudo-random sequences. The sequence is selected based on a predetermined selection rule. The radio identifier is selected from the thus selected sequence according to a predetermined deterministic update pattern associated with the selected sequence. The associated transmission power and/or transmission frequency is dynamically varied on the transmitter side according to a predetermined deterministic variation scheme.
