Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple component connections are used to connect rocker arms to knife angle bracket profiles, then the connection can be achieved, but the mounting and repair process becomes complex and costly
Solution Approach 1:
The patent combines multiple separate connection components into a single integrated connecting component that directly links the rocker arm to the knife angle bracket profile. This merging eliminates intermediate components and simplifies the mounting process while maintaining connection reliability through a unified structural design.
Solution Approach 2:
The connecting component is designed with multi-functional capabilities, serving both as a structural link and a mounting interface for cutting elements. This universal component replaces multiple specialized parts, reducing overall system complexity while maintaining all necessary connection functions.
2Reliability
If multiple component connections are used to connect rocker arms to knife angle bracket profiles, then the connection can be achieved, but the repair process becomes complex when damage occurs
Solution Approach 1:
The patent segments the cutting mechanism into modular components where the connecting component can be independently replaced. When damage occurs to the knife angle bracket profile or connecting component, only the damaged segment needs to be replaced rather than the entire assembly, greatly simplifying the repair process while maintaining connection reliability.
3Strength
If rigid connections are used between components, then structural strength is improved, but the cutting mechanism cannot adapt to uneven ground surfaces
Solution Approach 1:
The patent employs dynamic connections that allow controlled movement between the rocker arm and knife angle bracket profile. The connecting component is designed with degrees of freedom that enable the cutting mechanism to adapt to uneven ground surfaces while maintaining sufficient structural strength through the rigid portions of the connection.
4Ease of manufacture
If simple connections are used between components, then ease of assembly is improved, but the connection may fail upon impact with foreign objects
Solution Approach 1:
The connecting component is designed with built-in cushioning features and impact absorption capabilities that prepare the connection for potential foreign object impacts. The structural design includes reinforcement elements and flexible connection points that absorb impact forces while maintaining the simplicity of the assembly process.
