Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional article storage facilities face difficulties in accurately determining target horizontal and vertical distance information for each storage section, leading to complex and time-consuming learning operations, which can result in increased motion distance and potential errors during assembly.
Innovation Solution
The article storage facility incorporates a control system that uses learning markers and detection means to simplify the learning of horizontal and vertical distance information by detecting at least one edge section of the marker in one direction and both edge sections in the other direction, allowing for efficient determination of target distance information and precise positioning of the transfer means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the transfer means is moved horizontally and vertically to detect both end sections of learning markers in both directions, then accurate target distance information can be determined, but the motion distance and time required for learning operations increase significantly
Solution Approach 1:
The learning marker is segmented into distinct edge sections (first end section, second end section, third end section, fourth end section) that can be detected independently. This segmentation allows the detection means to extract horizontal and vertical distance information from different edge sections, reducing the need for comprehensive detection of all marker boundaries in both directions.
Solution Approach 2:
The solution transitions from detecting markers in both horizontal and vertical directions to utilizing edge section detection that primarily relies on horizontal movement. By detecting both end sections in the horizontal direction and both end sections in the vertical direction separately, the system reduces redundant motion and simplifies the learning process dimensionality.
2Reliability
If the transfer means is moved to detect learning markers in both horizontal and vertical directions, then complete learning information is obtained, but the complexity of the learning operation increases
Solution Approach 1:
The learning marker is divided into four distinct end sections (first, second, third, fourth) that can be detected independently. This segmentation allows the control means to process learning information in a structured manner by identifying specific edge sections, thereby reducing operational complexity while maintaining information completeness.
Solution Approach 2:
The learning marker is pre-configured with distinct end sections that are identifiable by the detection means. This preliminary structuring of the marker enables the system to automatically extract necessary learning information without requiring complex detection algorithms or multiple detection passes, thereby reducing learning operation complexity.
3Manufacturing precision
If both end sections of the learning marker are detected in both horizontal and vertical directions, then accurate positioning is achieved, but the motion distance of the transfer means increases
Solution Approach 1:
The learning marker is segmented into four end sections positioned at different locations. By detecting specific end sections (both in horizontal and vertical directions) rather than requiring complete perimeter detection, the transfer means can achieve accurate positioning with reduced motion distance.
Solution Approach 2:
The system detects only the necessary end sections of the learning marker required for accurate positioning, rather than detecting the entire marker boundary. This partial detection approach achieves sufficient positioning accuracy while minimizing the motion distance the transfer means must travel.

AI summary
A learning marker configured such that one of learning horizontal distance information and learning vertical distance information can be learned based on detection information from a horizontal travel distance detection device or a vertical travel distance detection device upon detection of at least one edge section of the learning marker in one direction of a horizontal travel direction and a vertical travel direction of a transfer means by a learning marker detector for detecting the learning marker, and the other of the learning horizontal distance information and learning vertical distance information can be learned based on detection information from the horizontal travel distance detection device or the vertical travel distance detection device upon detection of each of both edge sections of the learning marker in the one direction by the learning marker detector.
