Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a slide-rail structure is used to adjust the height for controlling slice thickness, then the thickness control capability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent changes the adjustment parameter from vertical slide-rail movement to horizontal platform rotation. By rotating the platform around a vertical axis, the distance between the cutting blade and the platform changes, thereby controlling slice thickness. This parameter change simplifies the structure while maintaining thickness control capability.
Solution Approach 2:
Instead of moving the cutting blade vertically to adjust slice thickness (conventional approach), the patent inverts the approach by rotating the platform horizontally. This inversion transforms a complex vertical adjustment mechanism into a simple rotational movement, reducing device complexity while achieving the same thickness control function.
2Manufacturing precision
If a conventional slide-rail structure is used for height adjustment, then thickness control is achieved, but reliability decreases due to blockage issues
Solution Approach 1:
The patent inverts the conventional vertical adjustment mechanism into a horizontal rotation mechanism. This inversion eliminates the slide-rail structure that is prone to blockage, thereby improving reliability while maintaining thickness control through the rotational adjustment of the platform position.
Solution Approach 2:
The patent extracts and removes the problematic slide-rail component from the system. By eliminating the slide-rail structure entirely and replacing it with a rotational platform mechanism, the source of blockage issues is removed, improving overall system reliability.
3Productivity
If repeated vertical cutting actions are performed to cut vegetables into strips, then strip cutting capability is achieved, but ease of operation deteriorates
Solution Approach 1:
The patent merges the slicing and strip-cutting functions into a single integrated operation. By rotating the platform to different angular positions, the user can achieve both slicing (when blade is perpendicular to vegetable) and strip cutting (when blade is at an angle) without separate operations, greatly improving ease of operation.
Solution Approach 2:
The patent introduces dynamic adjustability through platform rotation, allowing the cutting angle to change continuously. This dynamic capability enables the user to switch between slicing and strip-cutting modes by simply rotating the platform, eliminating the need for repeated fixed-angle cutting actions.
