Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement method is used to evaluate cervical spine proprioception, then the evaluation can be performed with simple equipment, but the measurement precision is low due to large errors
Solution Approach 1:
The patent replaces the manual mechanical measurement system with an electronic detection system. A detection module equipped with sensors automatically detects head movement angles and positions, substituting the evaluator's manual protractor measurements. This electronic substitution eliminates human error in reading and recording, significantly improving measurement precision while accepting increased device complexity.
Solution Approach 2:
The patent creates a digital copy of the measurement process through automated detection and data recording. Instead of manually recording angles on paper, the system digitally captures movement data, processes it through algorithms, and generates evaluation results automatically. This digital copying enables precise measurement and analysis while managing device complexity through software-based solutions.
2Measurement precision
If automated detection device is used to improve measurement precision, then the evaluation accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent designs the detection device to perform multiple functions: detecting head position, measuring movement angles, recording data, processing results, and providing feedback. By integrating these functions into a single multi-functional system rather than separate devices, the patent improves evaluation accuracy while managing overall device complexity through functional integration.
Solution Approach 2:
The patent combines the detection module, data processing unit, and feedback mechanism into an integrated evaluation system. The detection module merges sensors, processors, and communication interfaces into a unified device that automatically completes the entire evaluation process, improving accuracy while containing complexity through systematic integration.
3Reliability
If multiple head movements are performed to improve evaluation reliability, then the evaluation reliability is improved, but the time consumption increases
Solution Approach 1:
The patent implements continuous automated detection throughout the evaluation process. As the subject performs multiple head movements, the detection module continuously tracks position and calculates angles in real-time without interruption. This continuous automated operation maintains high evaluation reliability through multiple measurements while reducing time consumption by eliminating manual recording delays and enabling parallel data processing.

AI summary
A device and a method for evaluating cervical spine proprioception are provided. The method includes: taking a first head movement under a movement posture as a reference, calculating angle differences between multiple head movements under the same movement posture and the first head movement, and averaging the angle differences to obtain an average angle difference; then operating a data terminal to calculate average angle differences under multiple movement postures, and averaging the average angle differences to obtain a resultant average angle difference; comparing the resultant average angle difference with a standard value, thereby evaluating cervical spine proprioception of the subject based on a difference between the resultant average angle difference and the standard value. The disclosure can accurately evaluate position errors of a cervical spine under different postures, thereby avoiding errors caused by manual measurement.
