Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a universal truck chassis is used to carry the inspection system, then mobility is achieved, but the system is limited by road regulations and requires operator steering control

Engineering Contradiction:
ImprovemobilityVSAvoidoperator steering control
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The inspection system is mounted on an automated guided vehicle (AGV) that autonomously navigates and transports itself without operator intervention. The AGV's self-guided movement capability eliminates the need for manual steering control while maintaining mobility across the port area.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical steering control is replaced with an automated guidance system that uses sensors, controllers, and navigation algorithms to steer the AGV autonomously. This substitutes human-operated mechanical control with an automated electromechanical system.

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

2Adaptability or versatility

If a track means is used to drive the inspection system, then flexible movement is achieved, but tracks of various paths must be laid and it is limited to fixed site use

Engineering Contradiction:
Improveflexible movementVSAvoidtrack infrastructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The inspection system is extracted from the constraint of fixed track infrastructure and mounted on a mobile AGV platform. This removes the dependency on pre-laid tracks while retaining the capability for flexible movement to various inspection locations throughout the port.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system transitions from a static track-based configuration to a dynamic mobile platform that can adapt its movement path in real-time. The AGV can dynamically adjust its route based on operational requirements without being constrained by fixed track geometry.

Inventive Principle:
Principle #15Dynamics

3Productivity

If existing mobile inspection systems are used, then inspection capability is provided, but they present poor flexibility and cannot achieve centralized control

Engineering Contradiction:
Improveinspection capabilityVSAvoidflexibility and centralized control
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The AGV-based inspection system serves multiple functions: it can be centrally controlled for coordinated operation with other port equipment, flexibly repositioned to different inspection locations, and integrated into the port's automated guided vehicle fleet for unified management. This multi-functionality addresses both centralized control and flexibility requirements.

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

4Productivity

If the detection mechanism is mounted on the AGV, then scanning inspection is effectuated by relative movement, but the detection mechanism needs to be rotatable to switch between deployed and retracted states

Engineering Contradiction:
Improvescanning inspection efficiencyVSAvoidrotatable detection mechanism
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The detection mechanism is designed with rotational capability that allows it to dynamically switch between deployed and retracted states. This dynamic configuration enables the detector to be positioned optimally for scanning operations when needed and retracted when not in use, balancing inspection efficiency with system compactness.

Inventive Principle:
Principle #15Dynamics
