Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automatic determination of articles taken out from shelf is implemented, then labor reduction is achieved, but determination precision is insufficient

Engineering Contradiction:
Improvelabor reductionVSAvoiddetermination precision
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent combines weight change data from weight sensors with movement data from depth sensors to determine article removal. This multi-source data fusion approach resolves the contradiction by maintaining automated determination while significantly improving precision through cross-validation of multiple detection modalities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces an intermediary processing system that correlates weight changes with hand movement trajectories. This intermediary layer reconciles the automated detection requirement with precision needs by filtering false positives and confirming article removal through coordinated sensor data analysis.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If weight sensor data alone is used for article determination, then device complexity is reduced, but determination precision deteriorates

Engineering Contradiction:
Improvesensor system complexityVSAvoidarticle determination precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent merges weight sensor data with depth sensor movement data to achieve precise article determination. This combination resolves the contradiction by using multiple sensor types where each compensates for the limitations of the other, improving precision without excessive complexity increase.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent makes the detection system multi-functional by using depth sensors that serve both movement detection and spatial analysis purposes. This universal approach improves determination precision while avoiding the need for separate specialized sensors for each function.

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

3Measurement precision

If multiple data types are combined for article determination, then determination precision is improved, but device complexity increases

Engineering Contradiction:
Improvearticle determination precisionVSAvoiddata processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the data processing into distinct modules: weight change detection, movement data acquisition, and correlated analysis. This segmentation resolves the contradiction by organizing complex multi-data processing into manageable, independent components that can be processed systematically.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary processing of weight and movement data separately before correlation analysis. This preliminary action resolves the contradiction by preparing data in advance, reducing the computational complexity of the final determination process while maintaining high precision through thorough data preparation.

Inventive Principle:
Principle #10Preliminary action

AI summary

An article information deduction apparatus (10) includes an acquisition unit (110) and an output unit (120). The acquisition unit (110) acquires data based on a change in a detected value of a weight sensor (30) (hereinafter described as weight change data). For example, the acquisition unit (110) determines data acquired by chronologically arranging data acquired from the weight sensor (30) as weight change data. Further, the acquisition unit (110) acquires data indicating a movement of a hand of a person positioned in a shelf-front space (hereinafter described as movement data). For example, the acquisition unit (110) acquires data acquired by chronologically arranging data output from a depth sensor (40) to the article information deduction apparatus (10) as movement data. The output unit (120) outputs article determination information of the article deduced to be taken out by the hand of the person positioned in the shelf-front space, by using the weight change data and the movement data.
