Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If moveable road barrier systems are used to create traffic barriers between opposing lanes, then traffic flow efficiency is improved through flexible lane management, but precise placement becomes difficult and collision risks increase

Engineering Contradiction:
Improvetraffic flow efficiencyVSAvoidbarrier placement precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent replaces manual mechanical placement operations with an automated barrier transfer machine that uses GPS guidance and automated positioning systems. The machine incorporates a control system that receives GPS coordinates and automatically positions barriers at precise locations, eliminating the imprecision of manual placement while maintaining the flexibility of moveable barriers.

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

Solution Approach 2:

The patent creates a digital copy or record of barrier locations through GPS tracking and data logging. The system records the precise coordinates where barriers are placed, creating a verifiable digital representation of barrier positions that can be used for verification, collision investigation, and repositioning accuracy.

Inventive Principle:
Principle #26Copying

2Manufacturing precision

If road barrier systems are positioned precisely manually, then placement accuracy may be achieved, but operator inexperience leads to errors and fault determination in collisions becomes difficult

Engineering Contradiction:
Improvebarrier placement accuracyVSAvoidfault determination reliability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent implements a feedback system where GPS tracking continuously monitors barrier locations and the control system receives real-time position data. This feedback loop allows the system to verify that barriers are placed at the correct locations and provides a recorded history of barrier positions for collision investigations, eliminating uncertainty about pre-collision barrier placement.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces GPS technology and data logging systems as intermediaries between the barrier placement operation and the verification process. These intermediary systems objectively record barrier locations without being influenced by operator skill levels, providing reliable, verifiable data for fault determination in collisions.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If barrier locations are not tracked, then the system remains simple, but evidence collection in collisions is difficult and operator training is impaired

Engineering Contradiction:
Improvesystem simplicityVSAvoidbarrier location information
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent enables the barrier transfer machine to automatically track and record its own operational data including barrier locations, timestamps, and GPS coordinates. The system serves itself by generating its own operational record without requiring external monitoring equipment or manual documentation, providing complete location information while maintaining operational simplicity.

Inventive Principle:
Principle #25Self-service
