Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional I-beams are curved and assembled on location to form a circular structure, then the structure can support heavy loads, but assembly precision and alignment are compromised due to material tolerances and cumulative errors
Solution Approach 1:
The circular structure is divided into multiple pre-fabricated sectional segments that are assembled on location. Each segment is manufactured with high precision in a controlled environment, and the segmentation allows for modular assembly while maintaining overall structural integrity and load-bearing capacity.
Solution Approach 2:
The base template is assembled beforehand in a controlled environment to define the precise circular path and component positions. This preliminary action ensures that when the main structure is assembled, all components align accurately with the predetermined circular geometry, eliminating cumulative alignment errors.
2Ease of operation
If rollers are evenly spaced with axles converging to a central point, then the carousel can rotate, but load distribution becomes uneven and maintenance requirements increase
Solution Approach 1:
The wheel assembly incorporates a suspension system that allows dynamic adjustment of wheel position and load distribution. The wheel can move vertically to accommodate variations in the carousel structure, and the suspension elements automatically balance the load, ensuring uniform weight distribution during rotation.
Solution Approach 2:
The preload assembly applies controlled preloading force to the wheel bearing, changing the operational parameters of the bearing to optimize load distribution. This preloading compensates for manufacturing tolerances and ensures consistent contact between the wheel and carousel, reducing uneven wear and maintenance needs.
3Stability of the object's composition
If a concrete casing is built and filled to form a rigid structure, then the structure gains strength and stability, but installation time and complexity increase significantly
Solution Approach 1:
The base structure is divided into multiple pre-fabricated concrete sections that are manufactured off-site and assembled on location. This segmentation allows parallel production of multiple sections, reducing overall installation time while maintaining the structural stability of the complete circular base.
Solution Approach 2:
The concrete base sections are pre-cast and cured in a controlled manufacturing environment before delivery to the installation site. This preliminary action ensures that the concrete reaches full strength before installation, eliminating the need for extended on-site curing time and accelerating the overall installation process.
4Device complexity
If the carousel is driven by friction between lower and upper structures, then the system is simple, but energy consumption increases and driving efficiency decreases
Solution Approach 1:
The friction-based driving system is replaced with a direct mechanical drive system where the driving assembly engages directly with the carousel structure through interlocking elements. This substitution eliminates energy loss through friction while maintaining mechanical simplicity, as the direct engagement provides more efficient power transmission.
