Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In block storage arrangements, the risk of container stacks tilting and overloading the holding device is high due to uneven distribution of load, which can lead to instability and potential damage, as the center of gravity of the containers is not accurately determined.
Innovation Solution
A container load center of gravity determination device using multiple weighing devices and optical recording devices is employed to assess the load distribution and center of gravity, generating warnings and selecting appropriate container receiving spaces to ensure even loading and prevent overloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If containers are stacked to maximize space utilization, then storage capacity is improved, but the risk of stack tilting and instability increases
Solution Approach 1:
The system performs preliminary determination of container mass and load center of gravity position before the container is stacked. This advance information allows the control unit to calculate the total load center of gravity of the stack in advance and determine the permissible stack height, preventing instability issues before they occur.
Solution Approach 2:
The system continuously monitors the stack configuration and recalculates the total load center of gravity when containers are added or removed. The control unit receives feedback from the weighing devices and optical recording devices, adjusts the permissible stack height dynamically, and provides feedback signals to guide safe stacking operations.
2Ease of operation
If containers with off-center loads are stacked, then storage operations are simplified, but the holding device becomes overloaded and stack stability decreases
Solution Approach 1:
The system determines the load center of gravity position of each container in advance using weighing devices and optical recording devices before the container is placed on the stack. This preliminary information allows the control unit to identify containers with significantly off-center loads and prevent their placement on the stack, protecting the holding device from overload.
Solution Approach 2:
The control unit continuously monitors the load center of gravity positions of containers in the stack and calculates the total load center of gravity. When a container is added or removed, the system recalculates and provides feedback to determine if the new configuration exceeds permissible limits, enabling dynamic adjustment of stacking operations.
3Quantity of substance
If stack height is increased to improve space utilization, then storage capacity is improved, but the risk of container stack toppling increases
Solution Approach 1:
The system calculates the permissible stack height in advance based on the determined mass and load center of gravity position of each container before stacking begins. This pre-calculation ensures that the stack height will not exceed the threshold that could cause toppling, allowing maximum safe utilization of vertical storage space.
Solution Approach 2:
The permissible stack height is not fixed but dynamically adjusted based on the actual load characteristics of each container. When containers with better load distribution are stacked, the permissible height increases, allowing greater storage capacity. The system continuously updates the permissible stack height as containers are added or removed from the stack.

This solution effectively minimizes the risk of container stacks tilting and overloading by determining the center of gravity and mass of each container, allowing for optimal placement and distribution of weight across the holding device, thereby maintaining stability and preventing damage.
Implementation Method 1
the center of gravity of the container load is determined by measuring the weight force at several different positions on the container
