Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a ball-based visual system is used to indicate slope angle, then the system is simple and easy to manufacture, but the measurement precision and reliability are insufficient for accurate tilt sensing
Solution Approach 1:
The patent replaces the mechanical ball-based visual system with electronic tilt sensors (accelerometers or gyroscopes) that electronically measure tilt angles along multiple axes. This substitution provides precise digital measurements while eliminating the mechanical limitations of the ball system, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The invention changes the measurement parameters by using electronic sensors that can accurately measure tilt angles along multiple orthogonal axes simultaneously. This allows for comprehensive tilt detection in three-dimensional space, significantly improving measurement precision compared to the single-axis ball system while managing complexity through integrated sensor modules.
2Reliability
If tilt sensors are placed remotely from the display, then the measurement reliability is improved by reducing interference, but the device complexity increases due to additional wiring and calibration requirements
Solution Approach 1:
The patent segments the tilt-sensing system into separate functional modules: remote tilt sensors positioned away from the display unit, connected via data communication interfaces. This segmentation allows the sensors to be placed in optimal locations for accurate measurement while maintaining reliable data transmission to the display, managing complexity through modular architecture.
Solution Approach 2:
The invention introduces an intermediary data communication interface between the remotely positioned tilt sensors and the display unit. This intermediary handles data transmission and calibration information, enabling reliable communication while simplifying the integration process and reducing the complexity burden of remote sensor placement.
