Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tension rod connection methods are used with multiple holes and precise alignment requirements, then secure connection is achieved, but assembly becomes cumbersome and time-consuming
Solution Approach 1:
The connection system is segmented into modular components: the grid ring with multiple recesses, the spacer ring with opening, and the tension rods. This segmentation allows each component to be independently positioned and assembled, eliminating the need for complex alignment between multiple holes while maintaining connection security through the grid ring's multiple attachment points.
Solution Approach 2:
The grid ring acts as an intermediary component between the spacer ring and the auxiliary wheel rim. It provides a standardized interface with multiple recesses that can accommodate tension rods at various positions, simplifying the connection process by eliminating the need for precise hole alignment while ensuring secure attachment through the mediator's multiple engagement points.
2Stability of the object's composition
If multiple holes and precise alignment are required for tension rod insertion, then stable connection is achieved, but manual effort and complexity increase
Solution Approach 1:
The grid ring serves multiple functions: it provides structural support, enables tension rod attachment at multiple positions, and facilitates alignment through its geometric pattern of recesses. This multi-functionality eliminates the need for separate alignment features and holes, reducing assembly complexity while maintaining connection stability through the grid ring's inherent structural properties.
Solution Approach 2:
The grid ring is pre-formed with multiple recesses at predetermined positions before assembly. This preliminary preparation of attachment points eliminates the need for field alignment and hole matching during assembly, reducing both manual effort and complexity while ensuring stable connections through the pre-established geometric configuration.
3Manufacturing precision
If traditional alignment methods are used for heavy agricultural vehicle wheels, then proper positioning is achieved, but assembly time and labor increase significantly
Solution Approach 1:
The grid ring and spacer ring are designed with geometrically symmetric patterns that create equipotential alignment conditions. The recesses in the grid ring correspond to openings in the spacer ring at multiple equivalent positions, allowing the auxiliary wheel rim to be attached at any rotational position without requiring precise angular alignment, thus eliminating time-consuming alignment procedures while maintaining proper wheel positioning.
Solution Approach 2:
The invention changes the alignment parameter from requiring precise angular positioning to allowing positional flexibility through the grid ring's multiple recesses. This parameter change from angular precision to positional equivalence enables rapid assembly of heavy agricultural vehicle wheels without sacrificing alignment precision, as the geometric pattern ensures proper positioning regardless of rotational orientation.
