Solution Overview
Problem
Existing communication devices using end-to-end protection methods require multiple components, including processors, which can be inefficient for managing states and are not optimized for smaller devices.
Innovation Solution
Implementing a hardware component, such as a finite-state machine, to manage communication states and execute end-to-end protection methods directly, reducing reliance on software processors and optimizing component size for smaller devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a processor is used to manage communication states and execute end-to-end protection methods, then the device has higher flexibility and processing capability, but the device complexity and component count increase
Solution Approach 1:
The patent extracts the state management and end-to-end protection functions from the general-purpose processor and implements them in a dedicated hardware component. This separation allows the processor to focus on high-level application logic while the hardware component handles specific communication protocols and security functions, reducing overall device complexity while maintaining processing capability.
Solution Approach 2:
The patent introduces a hardware component as an intermediary between the processor and the communication bus. This intermediary layer handles state management and end-to-end protection, acting as a mediator that offloads specific functions from the processor, thereby reducing the processor's burden and simplifying the overall system architecture.
2Reliability
If multiple components are used for end-to-end protection, then the protection reliability is improved, but the device size and component count increase
Solution Approach 1:
The patent combines state management and end-to-end protection functions into a single integrated hardware component. This component includes state machine logic for managing communication states and end-to-end protection logic for verifying message integrity, merging multiple functions that would traditionally require separate components into one unified unit.
Solution Approach 2:
The hardware component is designed to perform multiple functions: it manages communication states (initialization, monitoring, error handling) and executes end-to-end protection methods (message validation, error detection). This multi-functional design reduces the need for separate dedicated components for each function.
3Adaptability or versatility
If state management is handled by software processors, then the system has higher flexibility, but the processing time and energy consumption increase
Solution Approach 1:
The patent replaces software-based state management with hardware-based state machine logic. The hardware component uses finite state machine (FSM) logic to automatically manage communication states, eliminating the need for software interpretation and reducing processing time. This substitution of mechanical/hardware logic for software processing accelerates state transitions and message handling.
