Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single image capture device is used to determine object dimensions, then the device complexity is reduced, but the measurement precision deteriorates due to lack of multi-perspective information
Solution Approach 1:
The patent combines data from multiple image capture devices (primary and secondary) to create a comprehensive representation of the object. The processing system merges image data, depth data, and spatial information from different devices and perspectives to improve dimensioning accuracy while managing device complexity through coordinated operation.
Solution Approach 2:
The patent transitions from two-dimensional single-perspective imaging to three-dimensional multi-perspective data collection. By incorporating depth data and spatial coordinates from multiple devices positioned at different locations, the system creates a volumetric understanding of the object that significantly improves measurement precision.
2Measurement precision
If multiple proximate image capture devices are used to obtain data from different perspectives, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The patent makes the image capture devices multi-functional by enabling them to serve both as primary and secondary devices depending on their operational context. Each device can capture images, depth data, and spatial information, and can function as either the primary dimensioning device or as a secondary proximate device, reducing overall system complexity through role flexibility.
Solution Approach 2:
The processing system acts as an intermediary that coordinates multiple image capture devices, managing their interactions and data flows. This central coordination layer simplifies the complexity by providing a unified interface for device management, data aggregation, and processing, rather than requiring direct peer-to-peer coordination between devices.
3Measurement precision
If image data from multiple perspectives is collected and combined, then the measurement precision improves, but the processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing spatial relationships, calibration data, and processing algorithms before actual dimensioning operations. Devices are pre-positioned and pre-configured with their spatial coordinates and operational parameters, allowing for faster real-time data processing during actual measurement operations without sacrificing precision.
Solution Approach 2:
The patent replaces complex mechanical coordinate transformation systems with computational methods. Instead of using complex mechanical linkages and physical reference frames to manage multi-perspective data, the system uses software-based coordinate systems, digital image processing, and algorithmic data fusion to efficiently combine data from multiple devices with minimal processing overhead.

AI summary
Methods and apparatus for dimensioning an object by enlisting proximate devices to obtain image data representative of the object from multiple perspectives are provided. An example method includes capturing, by a first image capture device, first image data representative of an object from a first perspective; determining whether a second image capture device is within proximity of the first image capture device; and when the second image capture device is within proximity of the first image capture device, sending a request to the second image capture device for second image data representative of the object from a second perspective, wherein the first image data and the second image data are combinable to form a composite representative of the object.
