Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for positioning large shell parts in structures like silos are labor-intensive and lack accuracy, as they rely on manual alignment and clamping, which is time-consuming and not always precise.
Innovation Solution
A device that supports shell parts from the inside and applies a positioning force from the outside using roller members to align and fix end flanges, allowing for automatic positioning and precise alignment through rotating movements, with adjustable supporting and clamping mechanisms to accommodate variations in curvature and diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual clamping and gripping tongs are used for positioning shell parts, then the positioning process can be completed, but the process becomes labor-intensive and time-consuming
Solution Approach 1:
The patent replaces manual mechanical positioning operations with an automated positioning device that uses rollers and positioning members to automatically align and position shell parts. The device mechanically substitutes human labor with automated mechanisms including motors, rollers, and positioning members that can precisely locate shell parts without manual intervention.
Solution Approach 2:
The positioning device enables the shell parts to be positioned automatically through self-aligning mechanisms. The rollers and positioning members work together to automatically guide the shell parts into correct positions without requiring continuous manual adjustment, allowing the system to service itself during the positioning process.
2Manufacturing precision
If manual clamping and gripping tongs are used for positioning shell parts, then the positioning process can be completed, but the positioning accuracy is insufficient
Solution Approach 1:
The patent replaces imprecise manual positioning with an automated mechanical system that uses rollers, positioning members, and control systems to achieve precise positioning. The mechanical substitution enables consistent and accurate positioning that exceeds what can be achieved manually with tongs and clamps.
Solution Approach 2:
The positioning device performs preliminary positioning actions before final assembly. The rollers and positioning members pre-align the shell parts in the correct positions and orientations, ensuring manufacturing precision is achieved before the parts are permanently fixed together.
3Productivity
If traditional positioning methods are used, then shell parts can be connected, but the process is labor-intensive requiring significant manual effort
Solution Approach 1:
The patent substitutes manual mechanical operations with an automated positioning system that uses motors, rollers, and positioning members to perform all positioning tasks automatically. This mechanical substitution dramatically improves productivity by eliminating the need for multiple workers to manually handle and position large shell parts.
Solution Approach 2:
The positioning device enables automated self-positioning of shell parts through its roller and positioning member mechanisms. The system services itself by automatically aligning, positioning, and securing shell parts without requiring continuous manual intervention, thereby significantly improving operational efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution significantly reduces manual labor and ensures accurate positioning of shell parts, enabling efficient and precise alignment of large shell parts, such as those in silo construction, by using a device with supporting and clamping rollers that can adjust to differences in diameter and curvature, facilitating easier and more accurate assembly.
Implementation Method 1
This solution significantly reduces manual labor and ensures accurate positioning of shell parts, allowing for efficient and precise alignment of large shell parts, even with varying diameters, and facilitates easy sealing by minimizing friction and requiring less force for positioning.

AI summary
Device and method for the mutual positioning of shell parts. Such shell parts can be used for constructing a large cylinder, for example a silo. The shell parts are provided with end flanges which extend at right angles thereto. Once the shell parts have been brought into the correct position, the end flanges are connected to one another in any suitable way. It is proposed to position the shell parts and/or end flanges with respect to one another in the desired position by arranging supporting rollers on the side where there are no end flanges. On the other side, clamping rollers are used which are at an angle to one another. A combination of in each case a supporting roller and a clamping roller provides both the correct mutual positioning of the shell parts with respect to one another and the pressing against one another of the shell parts.
