Power-Limiting Module for Communication Device Data Rate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data network failures due to overload are not effectively addressed by existing methods, as they often rely on limiting the number of messages or interrupts at switches without targeting the source of the issue, and require complex control logics and external counters.
Innovation Solution
A communication device with a power-limiting module that restricts the energy supply to the transmitter portion, ensuring a defined maximum data transmission rate is not exceeded, thereby limiting data transmission without the need for external control logics or counters, and allowing the receiver to continue operating independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of messages or interrupts is limited at switches, then network overload is reduced, but the source of the trouble is not addressed and complex control logics are required
Solution Approach 1:
The patent extracts the traffic limiting function from the network switch and relocates it to the end device (communication device). By placing the limiter at the source rather than at intermediate switches, the solution addresses the root cause of overload while simplifying network infrastructure requirements.
Solution Approach 2:
The communication device autonomously limits its own data transmission through an energy storage device and limiter circuitry. This self-limiting mechanism eliminates the need for external control logics or switch-based management, allowing the device to self-regulate traffic based on its energy capacity.
2Productivity
If limiting control logics and external counters are used to decide transmissions, then data transmission can be controlled, but device complexity increases
Solution Approach 1:
The patent replaces software-based control logics and counters with a hardware-based energy limiting system. The energy storage device and limiter circuitry provide physical constraints on data transmission, eliminating the need for complex software control mechanisms while maintaining effective traffic management.
Solution Approach 2:
The patent changes the control parameter from logical/message-based counting to energy-based physical constraints. By limiting the energy supplied to the transmitter through an energy storage device with a limiter, the system controls data transmission through physical energy availability rather than software counters.
3Productivity
If energy is limited to the transmitter portion, then data transmission rate is passively limited, but the receiver continues to function independently
Solution Approach 1:
The patent segments the power supply into separate paths: one path through the energy storage device and limiter for the transmitter, and another direct path for the receiver. This segmentation allows independent control of transmitter energy while maintaining uninterrupted receiver power supply, enabling selective traffic limiting without affecting reception capabilities.

AI summary
A communication device (1) is provided with a power-limiting module (11) connected to the power supply (12) and configured to limit energy supplied to the transmitter portion (141) such that a defined maximum data transmission rate is not exceeded. The power-limiting module (11) comprises an energy storage device (111), supplying energy to the transmitter portion (141), and a limiter (112) limiting recharging of the energy storage device (111) by the power supply (12). The energy storage device (111) and the limiter (112) are selected such that a defined maximum energy is suppliable to the transmitter portion (141), limiting the transmitter portion (141) to transmit data at the maximum data transmission rate. Limiting the energy supplied to the transmitter portion (141) ensures that the communication device (1) does not transmit over the network more than a given, limited amount of information per time unit, thus, the quantity of data transmitted by the communication device (1) is limited.
