Ultra-Wideband Object Identification in Warehouses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for identifying contents in boxes or packages in warehouses and factories are either cumbersome (manual inspection), prone to errors (weight-based methods), or costly and risky (X-ray irradiation), especially when the contents are not visible.
Innovation Solution
An ultra-wideband-based object identification method that transmits and receives signals to determine the identity of objects within containers, comparing the reflected signals with predetermined signals to identify the object, using a processor and display for matching indices and alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection is used to check box contents, then identification accuracy is improved, but operation convenience deteriorates
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated ultra-wideband signal-based detection system. The transmitter sends signals that reflect off objects in the box, and the receiver processes these reflections to automatically identify contents, eliminating the need for manual opening and visual inspection while maintaining high accuracy.
2Ease of operation
If weight-based method is used to identify objects, then operation convenience is improved, but measurement precision deteriorates
Solution Approach 1:
The patent replaces weight-based mechanical measurement with electromagnetic signal-based detection. Instead of weighing the box and inferring contents, the system uses ultra-wideband signals that interact with the physical properties and shape of objects, providing more precise identification while maintaining automated operation.
3Measurement precision
If X-ray irradiation is used to inspect objects, then measurement precision is improved, but harmful factors increase
Solution Approach 1:
The patent converts the potentially harmful X-ray approach into a safe alternative by using non-ionizing ultra-wideband electromagnetic signals. These signals provide sufficient penetration to detect objects through packaging without the harmful ionizing radiation effects of X-rays, thus eliminating the harmful factor while maintaining detection capability.
Solution Approach 2:
The patent uses safe, non-ionizing ultra-wideband signals instead of expensive and potentially harmful X-ray equipment. The ultra-wideband system is more cost-effective and eliminates the need for expensive radiation safety infrastructure while providing sufficient detection accuracy for the application.
4Measurement precision
If X-ray equipment is used for inspection, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces expensive, complex X-ray equipment with simpler, more affordable ultra-wideband transmitters and receivers. The ultra-wideband system uses commercially available components that are significantly less costly and simpler to implement while achieving the same object identification goal.
