Pivoting Device Modular Assembly for Heavy Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pivoting devices for structures like doors and gates are complex and difficult to assemble, especially for heavy structures, requiring significant effort and being non-versatile due to the need for custom hinging bodies and attachment elements, and often necessitate welding, which complicates assembly and makes replacement difficult.
Innovation Solution
A pivoting device with a plate attached to a wall, featuring a first and second pivoting body connected along orthogonal axes, an attachment element, and adjustable through holes allowing rotation and adjustment to fit various upright shapes and sizes, facilitating easy assembly and adaptation to different structures without extensive effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pintles with hinging bodies and attachment elements are used, then the structure can be securely attached to the wall, but the assembly process becomes complex and requires significant effort, especially for heavy structures
Solution Approach 1:
The pivoting device is divided into separate modular components: a plate for wall attachment, a first pivoting body connected to the plate, a second pivoting body that pivots to the first, and an attachment element that surrounds the upright. This segmentation allows each component to be independently positioned and connected, simplifying the assembly process while maintaining secure attachment through the multi-part construction.
Solution Approach 2:
The first and second pivoting bodies act as intermediary elements between the plate and the attachment element. These intermediaries facilitate the connection process by providing pivoting joints that allow for alignment and adjustment during assembly, reducing the effort required to connect heavy structures to the wall.
2Manufacturing precision
If custom hinging bodies and attachment elements are designed for specific upright shapes, then the pivoting device fits the structure precisely, but the device loses versatility and cannot be applied to different types of structures
Solution Approach 1:
The attachment element is designed with a universal seating structure that can accommodate different upright shapes (circular, square, rectangular sections). The pivoting bodies with their orthogonal rotation axes provide a standardized connection interface that works with various structure types, eliminating the need for custom-designed hinging bodies for each specific upright shape while maintaining precise fit through the seating mechanism.
Solution Approach 2:
The pivoting bodies incorporate dynamic adjustment capabilities with orthogonal rotation axes, allowing the attachment element to be positioned and oriented to match different upright geometries. This dynamic adjustability enables a single standardized design to adapt to various structure types, maintaining manufacturing precision across different applications without sacrificing versatility.
3Reliability
If welding is used to guarantee the association of the pintle with the upright, then the connection is strong and reliable, but the assembly process becomes more complex and the structure cannot be easily modified or replaced
Solution Approach 1:
The invention replaces welding (a thermal/chemical joining process) with a mechanical connection system consisting of pivoting bodies with rotation axes and an attachment element with a seating. This mechanical substitution maintains strong and reliable connections through the pivoting joint mechanism while eliminating the complexity of welding operations and enabling easy disassembly and replacement of the pintle without damaging the structure.
4Reliability
If multiple operators are present to lift and assemble heavy structures, then the structure can be properly positioned and connected, but the assembly process requires more resources and time
Solution Approach 1:
The pivoting device incorporates a plate that attaches to the wall and serves as an anchor point, effectively counterbalancing the weight of the structure during assembly. The pivoting bodies with their rotation axes provide mechanical advantage that reduces the lifting effort required, allowing proper positioning of heavy structures with fewer operators while maintaining assembly reliability.
