Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional measurement methods (tape measure) are used, then the device complexity is low, but the measurement precision is poor due to wrong position and method
Solution Approach 1:
The patent replaces the mechanical tape measure system with an optical measurement system using TOF camera and depth sensing technology. The controller processes depth images and body line images to automatically calculate body measurements, eliminating the need for manual tape measure operation and significantly improving measurement accuracy while maintaining ease of use.
Solution Approach 2:
The patent creates a digital copy of the user's body through depth imaging and body line generation. Instead of direct physical measurement with tape, the system captures the body shape as a digital depth map and generates simplified body line representations that can be measured automatically, improving both accuracy and convenience.
2Measurement precision
If 3D scanner or digital cameras are used, then the measurement precision is improved, but the device complexity and cost increase requiring specific place and expensive equipment
Solution Approach 1:
The patent makes the measurement device universally applicable by using a TOF camera that can be integrated into common devices like smartphones or mirrors. The system performs multiple functions including depth mapping, body line generation, pose estimation, and measurement calculation within a single integrated device, eliminating the need for specialized measurement locations and expensive dedicated equipment.
Solution Approach 2:
The patent replaces expensive, complex 3D scanning equipment with more affordable TOF camera technology. The system uses cost-effective depth sensing components that can be mass-produced and integrated into consumer devices, making accurate body measurement accessible to general consumers without requiring specialized facilities.
3Measurement precision
If multiple digital cameras are used, then the measurement precision is improved, but the device complexity increases requiring specific place and expensive equipment
Solution Approach 1:
The patent combines RGB imaging and depth sensing into a single integrated TOF camera system. Instead of using multiple separate digital cameras positioned at different locations, the system merges color and depth capture into one device, simplifying the overall system complexity while maintaining the ability to generate accurate body measurements through combined image processing.

AI summary
A body measurement device and a method for controlling the same are disclosed. The body measurement device comprises a TOF camera capturing a first image that includes an RGB image and a depth image; a display displaying a graphic image; and a controller estimating a user's pose based on the first image, controlling the TOF camera to automatically capture a second image, which includes the user's body image in front of the camera, if the user's pose is a first pose, generating the user's body line image based on the captured second image, measuring the user's body size based on the generated body line image; and controlling the display to display the user's body size.
