Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In materials handling facilities, accurately determining the dimensions of items is challenging, leading to inefficiencies in storage and shipping, as well as increased costs due to inappropriate container selection and potential item damage, especially when dealing with diverse and changing inventory.
Innovation Solution
A computer-implemented method for estimating item dimensions based on the dimensions of containers and paths used in handling items, allowing for continuous refinement of these estimates as items are handled, and recommending suitable containers or paths for storage and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If visual assessment method is used to determine item dimensions, then no additional measurement equipment is needed, but container selection accuracy deteriorates leading to higher costs and potential item damage
Solution Approach 1:
The patent replaces manual visual assessment with an automated image processing system that captures images of items and uses computer vision algorithms to automatically determine dimensions. This substitution of mechanical/manual measurement with optical/electronic systems resolves the contradiction by providing both automation (maintaining ease of operation) and improved measurement accuracy.
Solution Approach 2:
The patent creates a digital copy (image) of the physical item and extracts dimensional information from this copy rather than requiring direct physical measurement. This allows multiple items to be measured simultaneously from a single image, improving efficiency while maintaining or enhancing accuracy through automated analysis.
2Measurement precision
If manual measurement of each item is performed, then accurate dimensions can be obtained, but time consumption and labor costs increase significantly
Solution Approach 1:
The patent merges multiple measurement operations into a single image capture and processing step. By capturing an image containing multiple items and processing them together through automated algorithms, the system achieves accurate dimensions for all items simultaneously, resolving the contradiction between accuracy and productivity.
Solution Approach 2:
The system enables items to be measured automatically without human intervention in the measurement process. The image processing algorithm autonomously identifies item boundaries, calculates dimensions, and outputs results, eliminating manual measurement labor while maintaining accuracy and significantly improving throughput.
3Loss of energy
If inappropriate containers are selected based on inaccurate dimension information, then storage space may be wasted, but item damage risk increases and re-work costs increase
Solution Approach 1:
The patent implements a feedback mechanism where the automated dimension measurement system provides accurate size information to the container selection process. This feedback loop ensures that container choices are based on precise dimensional data, optimizing space utilization while preventing item damage through appropriate container matching, thus resolving the contradiction between space efficiency and reliability.

AI summary
A computer-implemented method for automatically determining estimated item dimensions may facilitate operations of a materials handling facility when exact dimensions of items are not known. Such a method may involve determining dimensions of a container, portal, or dimensionally constrained path in which an instance of a given item is handled and determining estimated dimensions of the item dependent on dimensions of the container, portal, or path. In some embodiments, the method may include determining dimensions of a second container, portal, or path in which an instance of the item is handled and updating the estimated item dimensions dependent on the dimensions of the second container, portal, or path. In some embodiments, the method may include recommending a container, portal, or path suitable for storing or transporting one or more items dependent on the estimated dimensions. In some embodiments, the estimated dimensions may facilitate identifying items in an inventory area.
