Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If large cranes are used to hoist tubular piles, then the lifting capacity is sufficient, but the cost increases exponentially and the construction site cannot meet the placement requirements
Solution Approach 1:
The patent divides the tubular pile into multiple sections that can be hoisted separately using smaller, more manageable lifting forces. Each section is then connected on-site through splicing operations, eliminating the need for single large-crane lifts and reducing both crane size requirements and associated costs.
Solution Approach 2:
The tubular pile sections are pre-fabricated and prepared at the factory before transportation to the construction site. This preliminary preparation includes creating connection interfaces and ensuring proper alignment features, allowing on-site assembly to proceed efficiently without requiring excessive lifting capacity during the actual installation phase.
2Device complexity
If traditional hoisting methods are used, then simple equipment is required, but excessive local stress is generated on the tubular pile
Solution Approach 1:
By dividing the tubular pile into multiple lighter sections, the local stress concentration points are distributed across multiple connection zones rather than concentrating the entire load at single hoisting points. This segmentation allows for more uniform stress distribution during both hoisting and connection operations.
Solution Approach 2:
The patent introduces specialized connection structures and splicing mechanisms that act as intermediaries between the hoisting equipment and the tubular pile sections. These intermediary components distribute the lifting forces more evenly across the pile sections and provide controlled stress transfer during connection, preventing excessive local stress while maintaining equipment simplicity.
3Device complexity
If traditional hoisting methods are used, then fewer control apparatuses are needed, but accurate adjustment of tubular pile spatial position cannot be achieved
Solution Approach 1:
The patent incorporates positioning sensors, measurement devices, and control systems that provide real-time feedback on the spatial position of tubular pile sections during hoisting and assembly. This feedback mechanism enables continuous monitoring and adjustment of position, ensuring precise alignment and placement accuracy while coordinating multiple control apparatuses through automated control loops.
Solution Approach 2:
The patent employs dynamically adjustable positioning mechanisms that can adapt their control parameters during the assembly process. The control apparatuses can modify their operation in real-time based on the current state of the structure being assembled, allowing for precise spatial positioning even as the configuration changes during construction. This dynamic control enables accurate positioning without requiring an excessive number of static control devices.
4Device complexity
If conventional assembly methods are used, then simple procedures are followed, but significant time is consumed in the hoisting process
Solution Approach 1:
By pre-fabricating tubular pile sections with connection interfaces and preparation features at the factory, the on-site assembly process is significantly accelerated. The preliminary preparation eliminates time-consuming field fabrication steps and allows for rapid connection of sections using standardized procedures, reducing overall hoisting and assembly time while maintaining procedural simplicity.
Solution Approach 2:
Dividing the tubular pile into pre-fabricated sections enables parallel preparation and transportation of multiple segments before assembly. This segmentation allows different sections to be ready simultaneously, and the modular nature of the sections facilitates quicker connection operations compared to assembling a single large piece, thereby reducing total hoisting process duration while keeping assembly procedures straightforward.
