Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional imaging devices are used to accurately capture body measurements, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent creates a digital 3D copy of the user's body through photogrammetry, capturing multiple 2D images and processing them into a accurate 3D model. This digital replica enables precise measurement extraction without requiring complex specialized imaging hardware, thereby resolving the contradiction between measurement precision and device complexity
Solution Approach 2:
The patent replaces traditional mechanical measurement tools and complex optical imaging systems with a computational approach using standard camera hardware. By substituting mechanical/optical complexity with digital image processing algorithms, the system achieves accurate 3D measurements while maintaining simple, accessible device requirements
2Measurement precision
If professional three-dimensional imaging devices are used, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements self-service functionality where users independently capture their own body measurements using a mobile device. The automated photogrammetry processing eliminates the need for professional operators, allowing users to perform the measurement task themselves while maintaining high precision through algorithmic 3D reconstruction
Solution Approach 2:
By creating an automated digital 3D model from multiple photographs, the system eliminates manual measurement procedures that require professional expertise. The computational copying and processing of images automates the measurement extraction, making the system easy for any user to operate while preserving measurement accuracy
3Ease of operation
If generalized sizing charts are used, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent transitions from generalized sizing charts to highly localized, individual-specific measurements by creating a unique 3D model for each user. This captures local variations in body shape, proportions, and contours that standardized charts cannot represent, thereby improving measurement precision while maintaining ease of use through automated processing
Solution Approach 2:
The patent changes the measurement parameters from standardized, categorical sizing chart values to continuous, precise 3D spatial coordinates. This transformation enables accurate representation of individual body dimensions while the automated system maintains ease of operation by eliminating manual chart consultation
4Reliability
If in-person consultations are used for health assessment, then reliability is improved, but loss of time increases
Solution Approach 1:
The patent performs preliminary action by capturing complete 3D body measurement data before the actual health consultation occurs. This pre-captured data eliminates the need for time-consuming in-person measurements during the consultation, allowing healthcare providers to review accurate measurements remotely while maintaining assessment reliability
5Ease of operation
If electronic two-dimensional imaging is used, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent transitions from two-dimensional electronic imaging to three-dimensional measurement by capturing depth information through photogrammetry. By adding the third dimension to standard 2D photographs, the system enables accurate measurement of physical characteristics while maintaining ease of operation through the use of conventional camera hardware
Data Source
AI summary
Digital imaging systems and methods are disclosed for detecting user-specific measurements. Digital image(s) of a user are obtained that depict one or more portions of the user's body. Body data is obtained specific to the user. A body imagery application (app) determines user-specific measurements of one or more portions of the user's body based on the digital image(s). The body imagery app determines a user-specific body-based confidence interval for the user based on the user-specific measurements and the body data. A health type-based identification of a user is generated that corresponds to one or more predefined health types based on one or more of the user-specific body-based confidence interval.
