Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a conventional centrifugal switch is used, then the device can detect when a preset rotation speed is reached, but it cannot provide detailed information about centrifugal force magnitude
Solution Approach 1:
The patent replaces the conventional mechanical switch mechanism with a sensing device that uses spring elements and contact-based sensing elements to detect and transmit centrifugal force information. The spring element deforms under centrifugal force, and this deformation is converted into electrical signals through contact-based sensing elements, providing detailed force information rather than simple on/off states.
Solution Approach 2:
The patent introduces a spring element as an intermediary between the rotating shaft and the sensing mechanism. The spring element translates centrifugal force into measurable deformation, which is then converted into electrical signals. This intermediary enables the transmission of detailed centrifugal force information while maintaining a relatively simple overall device structure.
2Loss of information
If a conventional centrifugal switch with simple on/off status is used, then the device structure remains simple, but the user cannot obtain detailed centrifugal force information
Solution Approach 1:
The patent replaces the binary mechanical switch state with a continuous measurement system using spring deformation and contact-based sensing elements. The spring element's deformation degree, which varies continuously with centrifugal force magnitude, is converted into proportional electrical signals, enabling precise measurement of centrifugal force rather than simple threshold detection.
3Measurement precision
If a centrifugal force sensing device with multiple components is implemented, then detailed sensing information can be obtained, but the device complexity increases
Solution Approach 1:
The patent designs the sensing device to perform multiple functions using a integrated structure. The same spring element and contact-based sensing elements are used to detect both rotation speed and rotation direction, eliminating the need for separate sensing mechanisms for each parameter and reducing overall device complexity while maintaining high measurement precision.
Solution Approach 2:
The patent combines the detection of rotation speed and rotation direction into a single integrated sensing mechanism. The contact-based sensing elements simultaneously capture both types of information from the spring element's deformation patterns, reducing the number of separate components needed and simplifying the overall device structure while achieving precise measurement of multiple parameters.
