Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual verification of implement-loader interoperability is performed, then equipment damage is prevented, but operator time and productivity are reduced

Engineering Contradiction:
Improveequipment safetyVSAvoidoperator productivity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system enables self-service by having the implement and loader automatically transmit their own identification and compatibility data to the verification device, eliminating the need for manual verification while maintaining equipment safety through automated compatibility checking

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical verification processes with an automated electronic verification system that uses optical scanners, processors, and display devices to automatically check implement-loader compatibility, thereby preventing equipment damage while maintaining operator productivity

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

2Manufacturing precision

If manual alignment of implement with load is performed, then proper engagement is achieved, but time spent on alignment tasks increases

Engineering Contradiction:
Improvealignment precisionVSAvoidalignment time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system replaces manual alignment operations with automated optical guidance that uses image capture devices, processors, and display devices to provide real-time visual feedback to the operator, achieving precise implement-load alignment while significantly reducing the time required for alignment tasks

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

Solution Approach 2:

The patent implements feedback by capturing images of the work area, processing the image data to determine alignment status, and displaying visual guidance information that provides real-time feedback to the operator on how to position the implement relative to the load for proper engagement

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If lateral repositioning of vehicle is performed to align tool carrier with implement, then coupling alignment is achieved, but operator efficiency is reduced

Engineering Contradiction:
Improvecoupling alignmentVSAvoidoperator efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The system provides real-time visual feedback by capturing images of the tool carrier and implement, processing the images to determine their relative positions and orientations, and displaying guidance information that shows the operator how to laterally reposition the vehicle to achieve proper coupling alignment without requiring multiple trial adjustments

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies preliminary action by providing advance visual guidance information that enables the operator to make the correct lateral repositioning movement on the first attempt, eliminating the need for repeated trial-and-error adjustments and improving operator efficiency

Inventive Principle:
Principle #10Preliminary action

4Manufacturing precision

If vehicle repositioning for inclination alignment is performed, then implement coupling is achieved, but time and productivity are lost

Engineering Contradiction:
Improveinclination alignmentVSAvoidrepositioning time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system provides real-time visual feedback by processing images to determine the inclination angles of the tool carrier and implement, and displaying guidance information that shows the operator how to reposition the vehicle to achieve proper inclination alignment, reducing the time required for this complex maneuver

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies preliminary action by providing advance visual guidance on the required vehicle repositioning movement before the operator executes it, enabling the operator to achieve proper inclination alignment on the first attempt and eliminating time-wasting trial-and-error adjustments

Inventive Principle:
Principle #10Preliminary action

AI summary

A virtual assist apparatus assists moving a tractor loader relative to a target item for mutually engaging the loader with the target item. An image sensor device generates target image data representative of a target item image. Based on the target image data, tractor heading data representative of a tractor heading of the tractor, and target alignment guidance data representative of a target approach path providing access to a target attachment feature of the target item that is mutually engageable with a corresponding loader attachment feature of the loader are determined. A display unit displays viewable images of tractor heading and the target approach path for assisting the movement of the tractor to position the loader relative to the target item for mutually engaging the loader with the target item. The target item may be an implement couplable with a tool carrier or a load engagable with the implement.
