Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cutting elements are adhered with random orientations, then the manufacturing process is simple and fast, but the cutting efficiency deteriorates due to disparities in heights and angles
Solution Approach 1:
The cutting elements are pre-formed with specific geometric features (flat surfaces, angles, and configurations) that enable them to self-align and stack in predetermined orientations. This preliminary preparation of the elements allows them to automatically achieve the desired cutting angles and heights when stacked, eliminating the need for complex post-assembly orientation control while maintaining high cutting efficiency
Solution Approach 2:
Each cutting element is designed with non-uniform local characteristics, including specific flat surfaces at predetermined angles, varying heights, and asymmetric geometries. These local quality variations enable each element to contribute differently to the overall cutting structure, allowing the stack to achieve consistent optimal cutting angles across all elements while maintaining manufacturing simplicity
2Manufacturing precision
If cutting elements are precisely formed using machining and molding, then the shape consistency is improved, but the manufacturing cost and time increase
Solution Approach 1:
The precise shaping and forming operations are performed on cutting elements during their initial manufacturing stage, before assembly. Each element is pre-formed with the exact geometry needed for its final position in the stack, including predetermined angles and flat surfaces. This eliminates the need for time-consuming post-assembly adjustments or orientations, reducing total manufacturing time while maintaining high precision
Solution Approach 2:
The cutting tool is divided into multiple discrete cutting elements that can be independently manufactured with precise geometries. Each segment (cutting element) is formed separately with specific shapes and angles, then assembled by stacking. This segmentation allows parallel manufacturing of multiple elements, reducing total production time while maintaining individual element precision
3Productivity
If cutting elements are stacked with consistent angles, then the cutting efficiency is improved, but the device complexity increases due to additional positioning features
Solution Approach 1:
Cutting elements are designed with asymmetric geometries, including non-uniform heights, angled flat surfaces, and irregular shapes. This asymmetry enables each element to naturally orient itself at the correct angle when stacked, with the gravity and geometric interlocking providing automatic positioning. The asymmetric design eliminates the need for complex mechanical positioning mechanisms while achieving consistent optimal cutting angles
Solution Approach 2:
The cutting elements incorporate self-aligning features such as flat surfaces at predetermined angles and complementary geometric profiles that enable automatic orientation during stacking. The elements self-position themselves without requiring external positioning devices, fixtures, or complex assembly mechanisms. This self-service capability achieves consistent cutting angles while minimizing device complexity

AI summary
A cutting device includes, at least one stack of cutting elements attached to a cutter surface having, a first element and a second element attached to the cutter surface. A third element is attached to the first element and the second element. The three elements are sized and shaped such that prior to attachment to the cutter surface the three elements are restable in a stable manner on the cutter surface due to gravity alone. A plane-defined-surface defined by one of the two planes of a modified gilmoid of the third element positioned further from the cutter surface is oriented at an angle of about 35 to 55 degrees relative to the cutter surface.
