Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional cutting assemblies are used, then cutting capability is achieved, but substantial cutting forces are required
Solution Approach 1:
The cutting assembly is divided into multiple independent tool holders, each equipped with cutting elements. These tool holders are arranged in sets around the cutter body, allowing the cutting action to be segmented across multiple points simultaneously, thereby reducing the force required at each individual cutting point while maintaining overall cutting efficiency.
Solution Approach 2:
Multiple tool holders with cutting elements are combined in predetermined sequences around the cutter body. This merging of multiple cutting actions into a single integrated assembly allows the distribution of cutting forces across multiple elements working in coordination, reducing the total force requirement compared to a single cutting element.
2Adaptability or versatility
If traditional cutting assemblies are used, then rock formation cutting is achieved, but adaptability to confined spaces is limited
Solution Approach 1:
The cutter body with multiple tool holders arranged in predetermined sequences is designed to be universally applicable in both above-ground and subterranean mining environments. The modular arrangement of tool holders allows the same basic assembly to adapt to different working conditions and space constraints, enhancing versatility without proportionally increasing complexity.
Solution Approach 2:
The tool holders are arranged in predetermined sequences around the circumferential surface of the cutter body, utilizing the three-dimensional space efficiently. This spatial arrangement allows the cutting assembly to operate effectively in confined subterranean spaces while maintaining the necessary cutting capability, transforming the traditional linear or single-point cutting approach into a multi-dimensional cutting pattern.
3Force
If multiple tool holders are arranged in predetermined sequences, then cutting force is reduced, but manufacturing complexity increases
Solution Approach 1:
Each tool holder is designed with specific local characteristics and arranged in predetermined sequences around the cutter body. This local differentiation allows each tool holder to be optimized for its specific position and function, while the modular design maintains ease of manufacture by allowing individual tool holders to be produced separately and then assembled in the predetermined sequence.
