Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different wheel bearing designs are used for driven and passive wheels, then each application gets optimized structural support, but device complexity and manufacturing variations increase
Solution Approach 1:
The wheel hub bore is designed with a universal geometry that can accommodate both driven and passive wheel applications. The bore includes a press-fit modification body that provides structural support for passive wheels, while also accommodating splined drive shafts for driven wheels. This single design serves multiple functions that previously required different hub configurations.
Solution Approach 2:
The wheel hub bore is segmented into two main components: the base hub bore and a press-fit modification body. This segmentation allows the modification body to be separately optimized for structural support in passive applications, while the base hub bore maintains compatibility with both application types. The modular approach enables independent optimization of each component.
2Stability of the object's composition
If additional structural support is added to passive wheel hubs, then structural rigidity improves, but device complexity and manufacturing steps increase
Solution Approach 1:
The modification body is press-fit into the wheel hub bore, merging two components into a unified structural assembly. This press-fit connection integrates the structural support function directly into the hub bore without requiring additional fasteners, welds, or complex assembly steps. The merged structure provides enhanced rigidity while maintaining manufacturing simplicity.
3Adaptability or versatility
If a modular wheel hub design is implemented, then versatility and manufacturing simplicity improve, but assembly steps may increase
Solution Approach 1:
The modification body is pre-configured with the appropriate geometry and features for the specific application (passive or driven) before being press-fit into the hub bore. This preliminary preparation allows the final assembly to be a simple single-step press-fit operation, rather than requiring complex in-situ modifications during assembly. The adaptability is built into the component design itself.
