Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous scanning is performed to quantify space within the container, then measurement precision is improved, but use of energy by stationary object worsens
Solution Approach 1:
The scanning sensor node performs periodic scanning at predetermined time intervals rather than continuous scanning. The processing unit is configured to perform the scanning operation cyclically, allowing the depth sensor to activate and capture images at specific intervals, then enter a low-power state between scans. This periodic operation maintains space quantification capability while significantly reducing battery power consumption compared to continuous operation.
2Adaptability or versatility
If multiple container configurations are supported to improve adaptability, then device complexity increases
Solution Approach 1:
The scanning sensor node is designed with universal functionality to support multiple container configurations including refrigerated containers, standard dry containers, and various rack types. The system achieves this through configurable scanning parameters and adaptable image processing algorithms that can handle different container geometries, sizes, and internal structures without requiring hardware modifications. The processing unit adjusts scanning patterns and reference frame selections based on the detected container type, enabling a single device to serve multiple container types.
3Productivity
If rapid scanning is performed to improve productivity, then measurement precision may worsen due to motion blur
Solution Approach 1:
The system performs preliminary actions to prepare for accurate scanning before the actual measurement process. Motion detection algorithms continuously monitor the container interior for movement, and the system waits for a predetermined period of no detected motion before initiating the scanning operation. This preliminary motion verification ensures that when scanning occurs, the container contents are stationary, eliminating motion blur and ensuring high measurement precision while maintaining overall productivity through efficient timing.

AI summary
Methods, apparatus, and systems are described for quantifying space within a container using a removable scanning sensor node. In general, the removable scanning sensor node identifies a type of the container, uses at least one depth sensor on the removable scanning sensor node to scan the space within the container to generate scan data, where the removable scanning sensor node is temporarily mounted within the container and above the space within the container, and where the depth sensor is oriented to scan the space within the container from above the space and within the container. The removable scanning sensor node then determines an unoccupied amount of the space within the container based upon the scan data.
