Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual techniques are used for hair transplantation and skin treatments, then device complexity is reduced, but positioning precision and measurement precision deteriorate
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated robotic system controlled by image processing and visual servoing. The robotic arm, guided by cameras and computer vision algorithms, achieves precise positioning without manual intervention, thereby improving positioning precision while accepting increased device complexity as a trade-off for enhanced accuracy and consistency.
2Manufacturing precision
If automated robotic systems are used, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback control system where cameras continuously capture images of the treatment area, the image processing system analyzes the images to determine tool position and orientation, and the robotic arm adjusts its position based on this feedback. This closed-loop visual servoing ensures high positioning accuracy and tool orientation precision, justifying the increased system complexity through improved procedural reliability and aesthetic outcomes.
3Productivity
If manual operations are performed, then ease of operation is maintained, but productivity and measurement precision deteriorate
Solution Approach 1:
The robotic system performs self-positioning and self-orientation using onboard cameras and image processing algorithms. The system autonomously tracks the treatment area, calculates the required tool positioning, and executes precise movements without requiring constant manual guidance. This self-service capability significantly improves productivity and measurement precision while the system manages its own operational complexity through integrated control algorithms.
4Measurement precision
If visual servoing with multiple cameras is implemented, then measurement precision is improved, but device complexity and loss of information increase
Solution Approach 1:
The patent divides the imaging system into multiple specialized camera units, each capturing specific views or features of the treatment area. The image processing system segments and integrates information from these separate camera inputs to construct a comprehensive three-dimensional model of the target area. This segmentation approach improves measurement precision by gathering data from multiple perspectives while managing information processing complexity through modular algorithms that handle each camera's data independently before synthesis.

AI summary
Automated systems and methods for operating a procedure tool to perform a procedure (for example, hair transplantation) on a body are provided. One or more mechanisms are configured to produce a combination movement of the procedure tool in response to control signals. A force sensor monitors resistance as the tool moves and transmits information from the force sensor to a computer. Movement of the procedure tool is controlled at least in part based on information from the force sensor.
