Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the microscope uses a single fixed measuring head configuration, then the device structure is simple, but it cannot switch between different measurement regimes quickly
Solution Approach 1:
The microscope is divided into multiple independent measuring heads (first measuring head for tunnel regime, second measuring head for atomic force regime), each capable of independent operation. This segmentation allows the system to switch between different measurement regimes by selecting which measuring head to use, rather than requiring complete reconfiguration of a single fixed system.
Solution Approach 2:
The microscope system is designed with universal functionality to perform multiple measurement types (tunnel regime and atomic force regime) through the use of multiple measuring heads that can be selectively positioned. The system can adapt to different measurement needs by activating the appropriate measuring head, making the device versatile without requiring complete redesign for each regime.
2Ease of operation
If the microscope requires complicated adjustment to change working regimes, then measurement precision can be maintained, but the ease of operation deteriorates
Solution Approach 1:
Each measuring head is pre-configured and calibrated for its specific measurement regime before use. The first measuring head is prepared for tunnel regime measurements and the second for atomic force regime measurements. This preliminary preparation eliminates the need for complicated adjustments when switching regimes, as each head is already optimized for its intended function.
Solution Approach 2:
The system incorporates dynamic positioning capabilities that allow the measuring heads to be moved between different positions (first position for tunnel regime, second position for atomic force regime) as needed. This dynamic repositioning enables quick regime switching while maintaining measurement precision, as each head can be accurately positioned for its specific measurement type.
3Adaptability or versatility
If the microscope allows frequent rework of adjustment by operator, then adaptability improves, but reliability deteriorates due to increased risk of error
Solution Approach 1:
Each measuring head is pre-calibrated and pre-configured for its specific measurement regime, eliminating the need for frequent operator adjustments. The first measuring head is prepared for tunnel regime and the second for atomic force regime, so switching between regimes simply requires positioning the appropriate pre-configured head, not re-adjusting parameters.
Solution Approach 2:
The system is designed so that each measuring head is self-contained and self-sufficient for its specific measurement regime. The heads contain their own configuration and calibration, so they can be switched between positions without requiring operator intervention for adjustment, thereby maintaining reliability while providing adaptability.
4Speed
If the microscope uses movable measuring heads on guides, then regime switching speed improves, but device complexity increases
Solution Approach 1:
The system uses separate guides (first guide for first measuring head, second guide for second measuring head) that allow independent movement of each measuring head. This segmentation of the positioning system enables quick switching between regimes by moving only the required head along its dedicated guide, rather than reconfiguring an entire complex positioning system.
Solution Approach 2:
The guides act as intermediary structures that facilitate the movement between measuring heads. By providing dedicated guides for each head, the system enables smooth transitions between measurement regimes without requiring complex direct coupling or complete system reconfiguration, thus improving switching speed while managing complexity through modular guide design.
