Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time position monitoring and adjustment is implemented, then imaging quality and treatment efficacy are improved, but device complexity and system requirements increase
Solution Approach 1:
The system is divided into multiple independent modules: mobile device for position detection, host for data processing, and operation device for execution. Each module performs a specific function, allowing the complex task of real-time position monitoring and adjustment to be distributed across simpler, specialized components.
Solution Approach 2:
The host acts as an intermediary between the mobile device and the operation device. It receives position information from the mobile device, processes the data, and sends control instructions to the operation device, thereby managing the complexity of real-time coordination between detection and execution components.
2Measurement precision
If real-time feature information acquisition is implemented, then motion monitoring accuracy is improved, but data processing requirements and system load increase
Solution Approach 1:
The system extracts only the necessary feature information (position coordinates and motion characteristics) from the captured images, rather than processing complete image data. This selective extraction reduces the data processing load while maintaining motion monitoring accuracy.
Solution Approach 2:
The system replaces complex mechanical monitoring equipment with computer vision-based detection using mobile devices. Image processing algorithms substitute for physical sensors, reducing hardware complexity and data processing requirements while maintaining measurement precision.
3Measurement precision
If guiding image projection is implemented, then subject positioning accuracy is improved, but additional equipment and operational steps are required
Solution Approach 1:
The mobile device serves multiple functions: it captures images for position detection, processes images to extract feature information, and projects guiding images for subject positioning. By consolidating these functions into a single multi-functional device, the system avoids adding separate equipment for each function.
Solution Approach 2:
The system uses the mobile device's existing imaging and processing capabilities to generate and project guiding images, allowing the device to serve itself rather than requiring external equipment. The same hardware used for detection is also used for guidance, reducing overall system complexity.

AI summary
An operation method, a device, a system and a mobile device for a medical device are disclosed. The method comprises: when it is detected that a target object reaches an operation area, projecting a first image in the operation area (S201), the first image being used for guiding the target object into a preset area; when the target object enters the preset area, acquiring position information of the target object on the preset area, and controlling, according to the position information, a target operation device to perform a first target operation (S202); and obtaining feature information of the target object in real time when the target operation device performs the first target operation, and controlling, according to the feature information, the target operation device to adjust the first target operation (S203). The accuracy of the first target operation performed by the target operation device is ensured.
