Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If fixed formation patterns are used for vehicular micro clouds, then formation stability is maintained, but resource utilization efficiency deteriorates due to varying computing capabilities among vehicle members

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidformation adaptability to varying capabilities
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic formation adjustment by continuously monitoring operational capabilities of vehicle members and automatically repositioning vehicles based on real-time performance data. The system transitions from static fixed formations to dynamic adaptive formations that optimize resource utilization while maintaining operational stability through controlled, incremental position changes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes formation parameters (vehicle positions, spacing, orientation) based on monitored operational capabilities. By adjusting these parameters dynamically, the system optimizes the match between vehicle capabilities and formation requirements, improving overall resource utilization efficiency without compromising formation integrity.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If vehicle positions are dynamically adjusted based on operational capabilities, then resource utilization improves, but formation stability deteriorates due to continuous position changes

Engineering Contradiction:
Improvemicro cloud operation performanceVSAvoidformation stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The system implements periodic formation adjustments rather than continuous changes. It monitors operational capabilities over time and executes position changes at optimal intervals when significant capability variations are detected. This periodic action maintains formation stability by limiting the frequency of disruptions while still achieving improved resource utilization through timely repositioning.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system continuously monitors operational capabilities of vehicle members and uses this feedback to make informed position adjustment decisions. By implementing closed-loop control where performance data feeds back into formation management, the system achieves adaptive optimization while maintaining stability through controlled, data-driven position changes rather than arbitrary movements.

Inventive Principle:
Principle #23Feedback

3Productivity

If monitoring and position adjustment mechanisms are implemented, then operation performance improves, but system complexity increases due to additional control modules and communication overhead

Engineering Contradiction:
Improvemicro cloud operation efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements multi-functional control modules that perform multiple tasks: monitoring operational capabilities, determining optimal positions, transmitting control signals, and adjusting formation patterns. By making these control components universal and multi-functional, the system reduces the number of separate specialized components needed, thereby managing complexity while achieving improved operation efficiency through integrated control.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

System, methods, and embodiments described herein relate to controlling a vehicular micro cloud, which may include a plurality of vehicle members each having respective positions in a formation and in which two or more of the vehicle members collaboratively execute at least one micro cloud operation. Control may be implemented to monitor performance of the at least one micro cloud operation, monitor operational capabilities of the vehicle members, determine, based at least in part on the operational capabilities of the vehicle members, a change in formation position for at least one of the vehicle members, wherein the change in formation position improves the performance of the at least one micro cloud operation and transmit one or more commands to cause the vehicle members to execute the change in formation position.
