Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional casted or welded rotary units are used in base frame, then mechanical stability is achieved, but device complexity and manufacturing effort increase significantly when accommodating design variations
Solution Approach 1:
The base frame is divided into modular components: standardized base frame structure, interchangeable rotary units, and configurable stiffeners. This segmentation allows different rotary units to be assembled into the same base frame without redesigning the entire structure, thereby accommodating design variations while reducing complexity.
Solution Approach 2:
The standardized base frame design serves multiple configurations and applications through universal mounting interfaces and standardized channel dimensions. A single base frame design can accommodate various rotary units and stiffener configurations, reducing the need for multiple specialized base frame designs.
2Strength
If additional stiffeners and elevator plates are added to base frame channels, then mechanical stability is improved, but device complexity and assembly effort increase
Solution Approach 1:
The stiffener configuration is made dynamic and configurable rather than fixed. Stiffeners and elevator plates can be selectively added or removed from base frame channels depending on the specific mechanical stability requirements of each application, allowing optimization without unnecessary complexity.
Solution Approach 2:
Stiffeners and elevator plates are placed locally in base frame channels only where mechanical stability is needed, rather than uniformly across all channels. This localized approach provides necessary strength while minimizing the number of components and assembly effort.
3Adaptability or versatility
If modular construction with interchangeable components is implemented, then adaptability to different applications is improved, but ensuring mechanical stability across all configurations becomes more difficult
Solution Approach 1:
The invention uses standardized parameters and dimensions for base frame channels, rotary units, and stiffeners that ensure mechanical stability across all configurations. By maintaining consistent critical parameters (channel dimensions, mounting hole patterns, material specifications), reliability is ensured while allowing adaptability through component interchangeability.
Solution Approach 2:
The base frame is designed with pre-configured standardized channels and mounting features that anticipate future component installations. This preliminary structuring ensures that when rotary units and stiffeners are assembled into the base frame, mechanical stability is automatically ensured through the pre-established standardized interfaces and load paths.
