Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If operators visually identify hazards and manually avoid collisions, then the system remains simple without additional detection equipment, but the safety and reliability are compromised due to human error and limited visual detection capability

Engineering Contradiction:
Improvecollision avoidance reliabilityVSAvoiddetection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the manual visual detection system with an automated optical detection system using cameras and image processing algorithms. The controller automatically identifies hazards in captured images and generates avoidance commands, substituting human visual inspection with machine-based optical detection and image analysis to improve reliability while maintaining operational simplicity

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

Solution Approach 2:

The patent introduces an intermediary optical hazard detection system that acts as a mediator between the aerial device and the environment. The system includes cameras, image processors, and controllers that serve as intermediaries to detect hazards, process visual information, and generate avoidance commands, thereby enhancing safety without requiring direct human visual monitoring

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the optical sensor captures multiple optical images to improve hazard detection accuracy using triangulation, then the measurement precision of hazard location is improved, but the loss of time for image acquisition and processing increases

Engineering Contradiction:

Solution Approach 1:

The patent applies preliminary action by continuously capturing multiple optical images as the boom assembly moves through space, even before a hazard is definitively identified. The controller accumulates image data and uses triangulation methods to calculate hazard location, preparing the information in advance to enable rapid and precise hazard localization when needed

Inventive Principle:

Solution Approach 2:

The optical sensor continuously captures images throughout the movement of the boom assembly, maintaining uninterrupted visual monitoring. This continuous image acquisition ensures that hazard detection and location precision are maintained without interruption, allowing the system to process images in real-time and respond immediately to detected hazards

Inventive Principle:
Principle #20Continuity of useful action
