Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional turntables are installed flush with the surface or below ground, then structural stability is improved, but installation complexity and excavation requirements increase
Solution Approach 1:
The turntable is divided into multiple wedge-shaped sections that can be assembled separately and then joined together to form a complete circular structure. This segmentation allows the turntable to be installed on the surface without requiring excavation, as each section can be positioned and secured independently while maintaining overall structural stability.
Solution Approach 2:
The invention transitions from traditional below-ground or flush installations to a surface-mounted configuration. By changing the installation dimension from subsurface to surface level, the turntable achieves structural stability through its design geometry and anchoring system without requiring excavation work.
2Power
If powerful motors are used to rotate the turntable, then rotational capability is improved, but power consumption and device complexity increase
Solution Approach 1:
The patent replaces traditional powerful mechanical motors with a more efficient drive system. The drive mechanism is positioned at the center of the turntable, allowing for more efficient force application and reduced power requirements. This central positioning optimizes the mechanical advantage and reduces the energy needed to rotate the entire structure.
Solution Approach 2:
The invention changes the operational parameters by using a centralized drive mechanism that applies force more efficiently. This parameter change in the drive system location and configuration reduces the power consumption required to achieve the same rotational capability compared to traditional edge-mounted motor systems.
3Ease of manufacture
If drive motors are mounted externally on the turntable, then ease of installation is improved, but the profile height increases and potential damage to vehicles occurs
Solution Approach 1:
The drive motors are nested within the wedge-shaped sections of the turntable structure. This nesting arrangement allows the motors to be housed inside the existing structural elements, maintaining a low profile while preserving ease of installation. The motors are integrated into the design rather than added as external protrusions.
Solution Approach 2:
The drive mechanism is merged with the central hub structure of the turntable. By combining the drive system with the central supporting element, the invention achieves a low-profile design where no components protrude above the surface, while maintaining ease of installation through integrated construction.
4Strength
If extensive installation work is performed, then structural integrity is improved, but installation time and cost increase
Solution Approach 1:
The turntable is segmented into modular wedge-shaped sections that can be manufactured separately and assembled on-site. This segmentation reduces installation time while maintaining structural integrity, as each section can be pre-formed with proper reinforcement and then joined using standardized connection methods.
Solution Approach 2:
The wedge-shaped sections are pre-formed and pre-assembled into complete circular turntables before delivery to the installation site. This preliminary action allows for quality control and structural reinforcement to be completed during manufacturing, reducing the need for extensive on-site work while ensuring structural integrity.
