Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing abacus-based training systems are used for multiple operations, then calculation training is provided, but the exact operation where mistakes are made cannot be identified
Solution Approach 1:
The system segments the calculation process into individual operations, with each operation having dedicated sensors that detect bead positions and determine whether the operation was performed correctly. This segmentation enables precise error detection at the operation level without requiring complex centralized analysis.
Solution Approach 2:
The system implements immediate feedback by comparing the detected bead configuration against the expected result for each operation. When an error is detected, the system provides real-time feedback to the student, enabling precise identification of where mistakes occur in the calculation sequence.
2Adaptability or versatility
If existing training systems accommodate all students, then group training is enabled, but individual skill levels cannot be differentiated
Solution Approach 1:
The system dynamically adjusts the difficulty level and type of mathematical operations based on each student's performance. The processing unit monitors accuracy and progression, automatically adapting the training regimen to match individual skill levels while maintaining group training functionality.
Solution Approach 2:
The abacus system is designed to serve multiple skill levels simultaneously through a universal interface. The same physical device can accommodate beginners working on basic operations while advanced students tackle complex calculations, with the system automatically differentiating and adapting to each user's needs.
3Reliability
If students make mistakes in low-level operations, then high-level operations must be performed, but accuracy decreases
Solution Approach 1:
The system performs preliminary validation of each operation before allowing progression to the next step. By checking bead positions and verifying operation correctness in advance, the system prevents accumulation of errors and ensures foundational accuracy before tackling more complex calculations.
Solution Approach 2:
The system replaces manual error checking with automated sensor-based detection and processing unit analysis. This substitution of mechanical verification with electronic detection improves reliability by eliminating human oversight errors and providing consistent, accurate validation of each calculation step.

AI summary
Provided is an apparatus for teaching calculation skills. The apparatus may include a plurality of beads and a set of columns of the cells being configured to be occupied by one of the beads. The apparatus may include a set of sensors configured to determine occupation of the cells by the beads, and a processing unit electronically coupled to the set of sensors. The processing unit can be configured to: receive from a server at least one array of integer numbers. Each of the integer numbers represents an intermediate result of solving of a sequence of mathematical operations displayed to a user; determine, via the set of sensors, occupation of the cells by the beads; translate the occupation of cells to a check number; and compare the check number to a current number in array to determine whether the current operation is solved correctly.
