Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional boards with drawing skills and brackets are used, then simplicity and ease of manufacture are maintained, but measurement precision and representation accuracy deteriorate
Solution Approach 1:
The patent replaces manual drawing operations with an automated plotting mechanism. A T-shaped ruler equipped with a felt-tip pen is moved by digital stepper motors along rails, eliminating the need for manual drawing while providing precise, programmable movement. This substitution of mechanical drawing with motorized positioning directly improves measurement precision while the modular design keeps complexity manageable.
Solution Approach 2:
The system incorporates self-measuring capabilities through integrated sensors and electronic measurement tools that automatically record and transmit data to the computer. The board serves itself by providing both the drawing surface and the measurement functionality, eliminating the need for separate measurement instruments and improving overall system precision.
2Adaptability or versatility
If two-dimensional representations are used, then device complexity is kept low, but comprehension of three-dimensional scientific concepts deteriorates
Solution Approach 1:
The patent transitions from two-dimensional drawing to three-dimensional representation by adding a vertical Z-axis through the tool holder car's ability to move perpendicular to the board surface. This enables the plotting of three-dimensional graphs and models, significantly enhancing the representation of spatial scientific concepts while maintaining a relatively simple board structure through modular design.
3Measurement precision
If virtual electronic white board projections are used, then modernity and interactivity are improved, but real three-dimensional measurement capabilities are lost
Solution Approach 1:
The patent merges the advantages of electronic control with physical measurement capabilities. The system combines digital stepper motors for precise control with a physical T-shaped ruler and felt-tip pen that create tangible markings on the board. This hybrid approach maintains ease of electronic operation while providing real, measurable three-dimensional representations, bridging the gap between virtual and physical learning tools.

AI summary
The present invention relates to a metal-sheet board or blackboard with magnetic features having two or three movements, which plots and represents reality in four dimensions (horizontal, vertical, depth and time) and which describes reality objectively, in which a T-shaped ruler is moved on a rail along the horizontal or X axis by a digital stepper motor controlled by a driver and software on the computer (horizontal movement). Furthermore, a tool truck surrounding the T-shaped ruler moves along the entire length (vertical movement) or Y axis thereof, actuated by a digital stepper motor controlled by a driver, which is in turn controlled by software on the computer, with these two movements controlled by mathematical speed and acceleration functions.
