Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If automated industrial vehicles use local sensor data only for navigation, then each vehicle can navigate autonomously, but the navigation accuracy is limited by sensor field of view and range

Engineering Contradiction:
Improvenavigation accuracyVSAvoidsensor system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines local sensor data from multiple automated vehicles to create a global map, merging individual vehicle perspectives into a comprehensive environmental model that provides better navigation accuracy for all vehicles

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system introduces a central server as an intermediary that collects, processes, and distributes global map data to vehicles, acting as a mediator that transforms limited local sensor data into enhanced navigation information

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If more forklifts and drivers are added to increase productivity, then task completion speed increases, but safety risks and operational complexity increase

Engineering Contradiction:
Improvetask completion rateVSAvoidsafety risks
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The automated industrial vehicles perform tasks autonomously using the global map for navigation, eliminating the need for human drivers and thereby removing safety risks associated with human operation of heavy machinery

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system replaces human-operated mechanical forklifts with automated vehicles that use sensor data and global mapping for navigation, substituting human control with automated systems that reduce safety hazards

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

3Adaptability or versatility

If human workers operate industrial vehicles in warehouses, then flexibility and adaptability are maintained, but safety concerns and labor costs increase

Engineering Contradiction:
Improveoperational flexibilityVSAvoidinjury risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The automated vehicles autonomously navigate and perform tasks using global map data, eliminating human involvement in dangerous operations while maintaining operational flexibility through programmable control

Inventive Principle:
Principle #25Self-service
