Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sensing distance is made adjustable to meet different user needs, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The sensing distance is made dynamically adjustable through a microcomputer control unit that allows real-time modification of the sensing threshold. The system transitions from a fixed sensing distance to a dynamic, user-adjustable parameter, enabling adaptation to different user heights and usage scenarios without requiring hardware changes.
Solution Approach 2:
The invention changes the sensing distance parameter from a fixed value to an adjustable variable. Through digital input keys, users can modify the sensing distance parameter stored in the microcomputer, allowing the system to adapt to different requirements (standing posture, sitting posture, countertop placement) by simply changing the parameter value rather than redesigning the hardware.
2Ease of operation
If the sensing distance adjustment is made simple and quick, then the ease of operation is improved, but the measurement precision may be compromised
Solution Approach 1:
The system incorporates a digital display that provides real-time feedback to the user about the current sensing distance setting. This feedback mechanism allows users to accurately know what sensing distance is currently active, ensuring measurement precision is maintained while enabling simple adjustment operations. The display shows the actual parameter value being used, eliminating uncertainty about the adjustment result.
Solution Approach 2:
The invention replaces complex mechanical adjustment mechanisms with an electronic control system. Instead of physical dials or switches that require precise mechanical positioning, the system uses digital input keys and microcomputer control to adjust the sensing distance, providing both simplicity of operation and digital precision in setting the parameter.
3Reliability
If the adjustment operation is protected from external influences, then the reliability is improved, but the ease of operation may be reduced
Solution Approach 1:
The microcomputer control unit acts as an intermediary between the user input (digital keys) and the sensing system. It processes the input signals, validates them, and applies the adjustments in a controlled manner, protecting the adjustment operation from external electrical influences or noise while maintaining user-friendly operation through the digital interface.
