Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual positioning methods are used for fill vehicles relative to commodity carts, then operators have flexibility in positioning, but the time spent positioning is excessive and efficiency is low

Engineering Contradiction:
Improvecommodity transfer efficiencyVSAvoidtime spent positioning fill vehicle
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical positioning with an automated optical guidance system. The system uses cameras mounted on the fill vehicle to capture images of the commodity cart, processes these images to determine precise positioning, and provides visual feedback to the operator. This substitution of manual positioning with automated image processing and visual guidance directly reduces positioning time while maintaining accuracy, thereby improving commodity transfer efficiency.

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

2Loss of time

If automated positioning systems are implemented, then positioning time is reduced and efficiency increases, but the device complexity increases

Engineering Contradiction:
Improvetime spent positioning fill vehicleVSAvoidpositioning system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent implements a multi-functional positioning system that performs multiple tasks: capturing images of the commodity cart, processing images to determine position and orientation, providing visual guidance feedback, and enabling automated positioning control. By consolidating these functions into an integrated system rather than separate components, the patent reduces overall system complexity while achieving automated positioning that significantly reduces positioning time.

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

3Measurement precision

If visual guidance systems are used to indicate desired fill vehicle position, then positioning accuracy is improved, but the device complexity increases

Engineering Contradiction:
Improvefill vehicle positioning accuracyVSAvoidguidance system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs visual guidance systems that use color-coded indicators to communicate positioning information to the operator. The system displays visual cues such as colored zones or markers that indicate the desired fill vehicle position and orientation relative to the commodity cart. This use of color changes and visual indicators provides precise positioning guidance in an intuitive manner, improving measurement precision while avoiding excessive system complexity by leveraging human visual perception capabilities.

Inventive Principle:
Principle #32Color changes
