Shelf Balance Optimization via Center of Gravity Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automatic storage systems, the lack of a clear pick-and-place principle leads to unbalanced shelves due to uneven weight distribution, causing system malfunctions and potential industrial accidents when transported by robots.
Innovation Solution
A method for calculating an object pick-and-place sequence that optimizes grid positions on shelves by determining the estimated center of gravity positions and selecting candidate grid positions within a balance standard area to ensure stable placement, using an electronic apparatus with a processor to coordinate grid positions and perform optimization calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed-point space selection and placement are performed without a clear pick-and-place principle, then the operation process is simple, but the shelves become unbalanced due to uneven weight distribution
Solution Approach 1:
The system changes the placement parameter from fixed-point selection to optimization-based position selection. By calculating the center of gravity position and comparing it with the shelf's balance standard area, the system dynamically determines the optimal placement position that maintains shelf balance while still following a systematic operation process.
2Productivity
If objects are placed on shelves without considering weight distribution, then the placement speed is fast, but the shelves may tilt or collapse during transportation
Solution Approach 1:
The system performs preliminary calculation of the center of gravity position and balance assessment before actual placement occurs. By pre-determining whether the estimated center of gravity falls within the balance standard area, the system prevents unstable placements before they can cause shelf tilting or collapse during transportation.
Solution Approach 2:
The system incorporates feedback by calculating the estimated center of gravity position and comparing it against the balance standard area. This feedback mechanism allows the system to adjust placement decisions to ensure shelf stability while maintaining efficient placement operations.
3Productivity
If unbalanced shelves are transported by robots, then the transportation process is straightforward, but the support shafts have shortened lifespan
Solution Approach 1:
The system applies preliminary anti-action by preventing unbalanced placements before they occur. By calculating the center of gravity and verifying it falls within the balance standard area, the system avoids creating conditions that would cause shelf tilting and excessive stress on support shafts during transportation, thereby extending their lifespan.

AI summary
A method for calculating an object pick-and-place sequence and an electronic apparatus for automatic storage pick-and-place are provided. When a warehousing operation is to be performed, the following steps are performed. A weight of an object to be stocked that is to be put on a shelf is obtained. The weight is substituted into a plurality of coordinate positions corresponding to a plurality of unused grid positions respectively, so as to calculate a plurality of estimated center of gravity positions. Whether the estimated center of gravity positions are located within a balance standard area is determined so as to sieve out a plurality of candidate grid positions from these unused grid positions. One of the candidate grid positions is selected as a recommended position of the object to be stocked.
