Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the effective range of the transmitter/receiver pair is increased by improving component performance (transmitted power output, receiver sensitivity, antenna efficiency), then the system reliability is improved, but the cost of system components increases

Engineering Contradiction:

Improvesystem reliabilityVSAvoidcomponent cost

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent changes the signal processing parameters by implementing forward error correction coding and repeat transmission protocols. These parameter changes in the communication protocol allow the system to achieve higher reliability without changing the physical components, thus avoiding increased component cost while improving system reliability.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the approach of improving mechanical/electrical components (transmitter power, receiver sensitivity, antenna efficiency) with a software-based signal processing approach. By using error correction algorithms and protocol modifications, the system achieves the same reliability improvement without the cost and complexity of upgrading hardware components.

Inventive Principle:

Solution Approach 1:

The patent modifies the signal processing parameters through forward error correction and repeat transmission mechanisms. These parameter changes enable the system to extend its effective range without requiring more expensive components, as the improvement is achieved through software-based error correction rather than hardware upgrades.

Inventive Principle:

Solution Approach 1:

The patent implements feedback mechanisms through error detection and correction protocols. The system continuously monitors transmission quality and adjusts retransmission strategies based on feedback signals. This feedback loop ensures that training commands are transmitted reliably, allowing the system to maintain effective training levels while avoiding unnecessary high stimulation by correcting errors before they reach the receiver.
