Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a practice device for violin fingering is provided with visual and auditory feedback systems, then the accuracy of practice determination and fingering memory deepening is improved, but the device complexity increases
Solution Approach 1:
The patent implements feedback mechanisms through visual displays that show correct vs. actual finger positions, and auditory feedback through speakers that provide guidance sounds. The control unit processes sensor data and generates appropriate feedback signals to guide learners, directly resolving the contradiction by enabling accurate practice determination through systematic feedback loops.
Solution Approach 2:
The patent replaces complex mechanical assessment mechanisms with electronic sensing and processing systems. Pressure sensors, position sensors, and microcontrollers substitute for manual evaluation methods, achieving precise measurement of finger positioning and practice accuracy while managing complexity through electronic integration rather than mechanical complexity.
2Adaptability or versatility
If a practice device for violin fingering includes adjustable components for different violin sizes, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The patent implements adjustable components including a movable support leg with length adjustment capability, and可调 finger pressing grooves that can be repositioned. These dynamic elements allow the device to adapt to different violin sizes and learner requirements, resolving the contradiction by providing versatility through controlled adjustability rather than fixed complex structures.
Solution Approach 2:
The patent designs the practice device with universal applicability through adjustable features that accommodate different violin types and sizes. The support structure, positioning mechanisms, and feedback systems are configured to work across multiple scenarios, achieving adaptability while managing complexity through standardized adjustable components.
3Measurement precision
If pressure sensors and position sensors are integrated into the finger pressing grooves, then the measurement precision of finger positioning is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent implements self-service functionality where the sensors automatically detect and record finger positioning without requiring manual intervention. The system autonomously processes sensor data, compares it with correct positions, and generates feedback, eliminating the need for learners to manually operate complex measurement mechanisms while maintaining high precision.
Solution Approach 2:
The patent introduces a control unit as an intermediary that mediates between the sensors and the feedback delivery system. This intermediary processes sensor data, determines accuracy, and generates appropriate feedback signals, simplifying the user interface while maintaining precise measurement capabilities through automated intermediate processing.

AI summary
The present disclosure relates to the technical field of violins, and in particular, to a practice device for violin fingering. Aiming at the problems of being unable to accurately determine the accuracy of practices and deepen fingering memory by reviewing the fingering for a violin, in the present disclosure, when fingertips press finger pressing grooves of pressing cylinders, light strips of the pressing cylinders illuminate, and as the pressing strength increases, colors of the light strips deepen and light becomes bright; and a camera records bending angles of fingers, and a recording box records the sound of pressing and knocking strength of the fingers, to help a practicer observe the force-generating state of fingers later, and perform targeted practices.
