Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If SATCOM operates in high power mode to maintain communication services, then communication quality is improved, but interference with nearby vehicles' navigation systems increases

Engineering Contradiction:
Improvecommunication qualityVSAvoidinterference with navigation systems
Core Design Contradiction:
Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The SATCOM system dynamically adjusts its power mode (high, low, or off) based on real-time detection of nearby vehicles and their distances. The control system monitors proximity and automatically switches between operational modes to optimize communication while minimizing interference with other vehicles' navigation systems.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the power parameter of SATCOM operation based on environmental conditions (proximity to other vehicles). By adjusting the power level from high to low or off depending on the detected distance to nearby vehicles, the system adapts its operational parameters to prevent harmful interference while maintaining adequate communication service.

Solution Approach 1:

The control system automatically detects nearby vehicles, calculates distances, determines appropriate SATCOM power modes, and executes mode switching without user intervention. The system monitors proximity data and autonomously manages SATCOM operation, eliminating the need for manual user decisions while maintaining communication service quality and preventing interference.

Inventive Principle:

Solution Approach 2:

The system continuously monitors proximity to other vehicles and uses this feedback to automatically adjust SATCOM power mode. The control system receives distance information, processes it against predefined thresholds, and dynamically switches between high, low, and off modes based on the detected environmental conditions, creating a closed-loop control system.
