Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If voice control systems are used in medical settings, then operator control capability is improved, but language misunderstandings and indistinct enunciation cause miscommunication and errors

Engineering Contradiction:
Improveoperator control capabilityVSAvoidcommunication accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces acoustic voice recognition with an electromechanical system that detects electrical signals from neck muscle movements. The sensor detects electromechanical activity in the neck muscles, which is then processed to generate control signals, substituting the acoustic field with an electromechanical detection system to eliminate language-related errors

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary electromechanical sensor system between the operator's intent and the equipment control. The sensor acts as a mediator that translates subtle neck muscle movements into control commands, providing a reliable intermediate step that avoids direct voice communication and its associated misunderstandings

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If voice commands are used for equipment control, then hands-free operation is achieved, but language barriers and enunciation issues lead to potential errors

Engineering Contradiction:
Improvehands-free operationVSAvoidcontrol signal accuracy
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent substitutes acoustic signal detection with electromechanical sensor detection. Instead of relying on voice commands that can be misunderstood, the system detects electrical signals from neck muscle movements, providing a more accurate and unambiguous control mechanism that maintains hands-free operation

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the detection parameter from acoustic properties of voice to electromechanical properties of muscle movement. This parameter change allows for more precise detection of operator intent, as electromechanical signals from muscles provide clearer, more distinct patterns than variations in voice enunciation

Inventive Principle:
Principle #35Parameter changes
