Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional complex structure is used to form the cabin, then the cabin can accommodate multiple components, but the assembly difficulty increases and body strength decreases
Solution Approach 1:
The cabin is divided into multiple modular components including first housing, second housing, first side plate, and second side plate. Each component can be independently manufactured and assembled, reducing overall assembly difficulty while maintaining the ability to accommodate multiple robot components.
Solution Approach 2:
The side plates serve multiple functions: they connect the housings together, provide mounting surfaces for motors, and incorporate air inlets for heat dissipation. This multi-functionality reduces the need for additional separate components.
2Adaptability or versatility
If traditional complex structure is used to form the cabin, then the cabin can accommodate multiple components, but the weight increases
Solution Approach 1:
By segmenting the cabin into modular parts, each piece can be optimized for minimal weight while maintaining structural integrity. The segmented design allows for more efficient material distribution compared to a monolithic complex structure.
3Adaptability or versatility
If traditional complex structure is used to form the cabin, then the cabin can accommodate multiple components, but the manufacturing cost increases
Solution Approach 1:
Segmented modular components can be manufactured independently using standardized processes, enabling parallel production and reducing overall manufacturing time and cost. Each module can be optimized for its specific manufacturing requirements.
4Strength
If traditional cabin design is used, then the structure can support components, but heat dissipation performance is poor
Solution Approach 1:
The side plates incorporate localized air inlet features that provide dedicated cooling channels to high-heat areas where motors are mounted. This localized heat dissipation design maintains structural strength while providing targeted thermal management.
