Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical cables and fiber optic links are used for data transfer, then reliable communication is achieved, but bandwidth limitations and high latency occur

Engineering Contradiction:
Improvecommunication reliabilityVSAvoiddata transfer speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the mechanical cable-based communication system with a wireless communication system using antennas and radio frequency signals. This substitution eliminates the physical constraints of cables (bandwidth limitations and latency) while maintaining communication reliability through proper antenna design, signal processing, and error correction mechanisms.

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

Solution Approach 2:

The patent changes the communication medium from electrical signals in cables to electromagnetic waves in free space. This parameter change enables higher data transfer speeds and reduced latency while maintaining reliability through appropriate frequency selection, power control, and signal processing techniques.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If cable routes are designed into aircraft structure during manufacturing, then stable communication infrastructure is established, but flexibility to adapt to new technologies is lost

Engineering Contradiction:
Improveinfrastructure stabilityVSAvoidtechnology adaptability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent replaces the fixed mechanical cable infrastructure with a wireless communication system that uses antennas and radio frequency signals. This substitution provides infrastructure stability through proper antenna placement and mounting while enabling high adaptability to new technologies, as wireless systems can be upgraded by software updates or antenna replacements without requiring structural modifications to the aircraft.

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

Solution Approach 2:

The patent introduces a dynamic communication system where wireless signals can be redirected, routed, and reconfigured through software control. This allows the communication infrastructure to adapt to new technologies and requirements without physical reconfiguration, while maintaining stable operation through controlled signal management and interference mitigation.

Inventive Principle:
Principle #15Dynamics

3Productivity

If long cable runs are used to connect remote sensors, then comprehensive monitoring is achieved, but substantial line losses occur

Engineering Contradiction:

Solution Approach 1:

The patent replaces long cable runs with wireless communication between remote sensors and the aircraft's communication system. This substitution eliminates signal loss associated with long cable runs while maintaining comprehensive monitoring coverage through strategically placed wireless sensors that transmit data via radio frequency signals without the attenuation problems of electrical cables.

Inventive Principle:

Solution Approach 1:

The patent replaces the complex mechanical cable installation and routing system with a wireless communication system. This substitution achieves reliable communication establishment through antenna placement and signal configuration, while dramatically reducing modification costs for upgrades or changes, as wireless systems can be modified by software updates or antenna replacements without costly retro-fitting or recertification processes.

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