Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If preset arrangement patterns are used to stack multiple articles on a support, then stacking efficiency is improved, but articles may fall into open areas causing damage or stack collapse

Engineering Contradiction:
Improvestacking efficiencyVSAvoidstack stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The determination processor performs preliminary analysis of arrangement patterns before actual stacking, identifying open areas that could cause articles to fall. The system modifies arrangement patterns in advance to eliminate such hazardous open areas, ensuring stack stability is built into the arrangement design before articles are physically stacked.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system incorporates feedback by analyzing the determined arrangement patterns and identifying potential falling risks. When open areas are detected that could cause articles to fall, the system feeds this information back to modify the arrangement pattern, creating an iterative improvement process that ensures both efficiency and stability.

Inventive Principle:
Principle #23Feedback

2Area of stationary object

If open areas are left in article layers, then space utilization is improved, but articles in upper layers may fall into these open areas

Engineering Contradiction:
Improvespace utilizationVSAvoidarticle falling risk
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The determination processor proactively identifies open areas that could become hazards and modifies arrangement patterns to prevent articles from falling into them. By taking preliminary anti-action against potential falling risks, the system maintains necessary open areas for space utilization while preventing the harmful effect of articles falling.

Inventive Principle:
Principle #9Preliminary anti-action

3Reliability

If arrangement patterns are modified to prevent falling, then stack stability is improved, but determination process complexity increases

Engineering Contradiction:
Improvestack stabilityVSAvoiddetermination process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary determination and modification of arrangement patterns using automated processing logic. By establishing clear determination criteria for open areas and falling risks in advance, the system manages complexity through structured algorithms rather than ad-hoc analysis, making the determination process systematic and efficient.

Inventive Principle:
Principle #10Preliminary action

AI summary

An article arrangement determination system includes a determination processor and a modification processor. The determination processor obtains lower-layer arrangement information indicating lower-layer article arrangement that is arrangement of articles included in a lower article layer and upper-layer arrangement information indicating upper-layer article arrangement that is arrangement of articles included in an upper article layer. The determination processor determines, in response to the lower-layer article arrangement having an open area, whether an article included in the upper article layer has a possibility of falling into the open area. The modification processor modifies the upper-layer arrangement information in response to determination that an article has the possibility of falling. The modification processor determines, in response to upper-layer article arrangement indicated by modified arrangement information resulting from modifying the upper-layer article arrangement having no possibility of falling, the modified arrangement information as new upper-layer arrangement information.
