Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If human operators perform loading tasks manually, then operational flexibility is maintained, but loading accuracy and efficiency deteriorate due to human error and misalignment

Engineering Contradiction:
Improveloading accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical operations with an automated system using sensors (cameras, LIDAR, radar) and machine perception algorithms to detect fiducial markers and calculate machine orientation, eliminating human error in alignment and positioning while maintaining operational flexibility through programmable control

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

Solution Approach 2:

The system uses fiducial markers as visual copies or representations of the hauling machine's position and orientation, allowing the loading machine to perceive and respond to the hauling machine's state without direct physical contact or complex mechanical coupling

Inventive Principle:
Principle #26Copying

2Productivity

If operators rely on visual contact to navigate difficult terrain and poor visibility, then situational awareness is maintained, but productivity deteriorates due to restricted line-of-sight requirements

Engineering Contradiction:
Improveloading efficiencyVSAvoidvisibility constraints
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces human visual perception with machine-based sensors (cameras, LIDAR, radar) that can operate independently of line-of-sight constraints, allowing the system to detect fiducial markers and calculate orientation even in poor visibility conditions, thereby maintaining productivity without human operators needing direct visual contact

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

Solution Approach 2:

The fiducial marker serves as an intermediary object that carries machine perception information through the environment, allowing the loading machine to acquire orientation data about the hauling machine without requiring direct visual or physical contact, overcoming terrain and visibility barriers

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If the hauling machine is angularly misaligned with the loading machine, then operational flexibility is maintained, but loading precision deteriorates due to misalignment

Engineering Contradiction:
Improveloading precisionVSAvoidalignment flexibility
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The system continuously detects the fiducial marker on the hauling machine, calculates its orientation and position relative to the loading machine, and uses this feedback information to guide the loading operation, automatically compensating for angular misalignment and maintaining high loading precision regardless of relative machine positions

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts loading guidance based on real-time detection of the hauling machine's orientation and position, allowing the loading machine to adapt its operations to changing relative positions and angles, thereby maintaining precision while preserving operational flexibility

Inventive Principle:
Principle #15Dynamics

AI summary

A loading system is constructed to load a hauling machine by a loading machine. The system includes a fiducial marker affixed to the hauling machine. A set of sensors of diverse sensory modalities is deployed on the loading machine that generate respective signals indicative of the fiducial marker in the corresponding sensor modalities. A processor on the loading machine determines a machine orientation in space of the hauling machine through machine perception applied to the signals. Loading the hauling machine by the loading machine is guided according to the machine orientation.
