Radar Scanning Station for Container Air Gap Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in warehouses is to efficiently open containers of varying sizes and shapes without damaging the items inside, as the thickness of the container sides and the air gap between items and the top surface can vary, making it difficult to determine the correct cutting depth and location for removing the top surface.
Innovation Solution
A scanning station equipped with articulating arms and radar sensors creates a 3D image of the container's interior, identifying air gaps and container thickness, providing precise instructions for a cutting station to cut the top surface without damaging the items, by determining the optimal blade depth and cut line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the deepest setting of a box cutter is used to compensate for various thicknesses of container sides, then the cutter can penetrate through the thickest sides, but the cutter may inadvertently contact and damage the items in the container
Solution Approach 1:
The system performs preliminary scanning of the container interior using radar sensors to detect the position of items and calculate the air gap before the cutting operation. This advance information allows the blade depth to be precisely configured for each specific container, preventing item damage while ensuring adequate penetration of the container walls.
Solution Approach 2:
The system uses radar sensors to continuously monitor and measure the air gap between container walls and contents, providing real-time feedback that is used to dynamically adjust the blade depth setting. This closed-loop control ensures the cutter penetrates the container walls effectively without contacting the items inside.
2Object-affected harmful factors
If suppliers are requested to leave a minimum gap to ensure the cutter does not contact items, then item protection is improved, but productivity decreases due to additional packaging space requirements
Solution Approach 1:
The system changes the critical parameter from a fixed minimum gap requirement to a dynamically determined blade depth setting based on actual air gap measurements. This allows containers to be packed more densely without increasing item damage risk, as the cutting parameters are adjusted to match the actual contents position rather than relying on conservative packaging constraints.
Solution Approach 2:
The system replaces the mechanical approach of enforcing a fixed minimum physical gap through packaging standards with a sensing and control system that uses radar to detect item positions and automatically adjusts cutting parameters, enabling more efficient space utilization without compromising safety.
3Adaptability or versatility
If various thicknesses of container sides are accommodated by using a fixed deep cutter setting, then compatibility with different container types is improved, but measurement precision of the air gap is lost
Solution Approach 1:
The system transitions from a static, fixed blade depth setting to a dynamic adjustment mechanism that modifies the cutting parameters based on real-time radar measurements of each container's specific characteristics. This allows the system to adapt to various container types and thicknesses while maintaining precise air gap detection and appropriate cutting depth for each case.

Function Achieved in This Case
This solution allows for safe and efficient removal of the top surface of containers, ensuring that items inside are not damaged, regardless of the container's size or shape, by accurately determining the air gap and thickness, enabling precise cutting instructions.
Implementation Method 1
A scanning station including a radar sensor scans a container to identify an air gap between one or more items in the container and a top surface of the container

AI summary
Embodiments herein describe a scanning station for identifying an air gap between one or more items stored in a container (e.g., a cardboard box) and a surface of the container (e.g., a top lid of the cardboard box). After identifying the air gap, in one embodiment, the scanning station provides instructions to a downstream cutting station where the container is cut opened. In one embodiment, the scanning station includes one or more articulating arms that each includes a scanner (e.g., a radar sensor) attached on an end of the articulating arm facing the container. Moving the articulating arms along the boundaries of the container provides a 3D image of the inside of the container. By processing this image, the scanning station can identify an air gap along a desired cut line as well as a thickness of the sides of the container.
