Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional cutting devices with fixed blades are used, then the structure is simple, but the cutting precision and repeatability deteriorate
Solution Approach 1:
The cutting device is divided into modular components: a support body with housing cavity, interchangeable cutting elements, and replaceable abutting blocks. This segmentation allows precise adjustment of cutting parameters while maintaining overall device simplicity.
Solution Approach 2:
The device incorporates adjustable and replaceable components rather than fixed structures. Cutting elements can be interchanged, and abutting blocks can be replaced to adjust total dimension, enabling dynamic adaptation to different cutting requirements while maintaining precision.
2Adaptability or versatility
If multiple cutting parts are used to achieve versatility, then the adaptability improves, but the number of parts increases and maintenance time worsens
Solution Approach 1:
The support body with housing cavity serves as a universal base that can accommodate different cutting elements and abutting blocks. This single support structure performs multiple functions by simply changing the interchangeable components, reducing the need for multiple specialized devices.
Solution Approach 2:
Worn or damaged cutting elements and abutting blocks can be easily removed and replaced with new ones. The modular design allows quick disposal of worn parts and recovery of the functional device without extensive disassembly or maintenance of the entire system.
3Manufacturing precision
If the total dimension of cutting components is fixed, then the manufacturing is simpler, but the ability to compensate for wear and maintain cut quality deteriorates
Solution Approach 1:
The total dimension of the modular insert is made variable through interchangeable abutting blocks with different dimensions. This allows the device to adapt to wear of cutting elements and maintain consistent cut quality by replacing blocks rather than the entire component.
Solution Approach 2:
The abutting blocks are provided in different dimensions to change the total dimension of the modular insert. This parameter variation allows compensation for wear on cutting elements while maintaining standardized manufacturing processes for the base support body and housing cavity.

AI summary
A cutting apparatus and a cutting device are disclosed comprising a modular insert arranged at least partially in a housing cavity, in which the modular insert includes a cutting element for performing a vertical or oblique cut and an abutting block which is interchangeable and couplable with the cutting element to fix a total dimension of the modular insert, in which an abutting face of the abutting block abuts on a back wall of the housing cavity so that a rear end of the cutting element is spaced away from the back wall. An assembly method is disclosed for assembling the aforesaid device comprising the steps of providing a plurality of interchangeable abutting blocks and of choosing an abutting block between the plurality of interchangeable abutting blocks on the basis of a desired total dimension of the modular insert.
