Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid/gas separation column insertion devices face challenges in gripping packing sections of varying diameters, as they do not all have the same diameter, making universal gripping difficult and requiring costly adaptations for each size.
Innovation Solution
A gripping device with a deployment module featuring a main upright and peripheral uprights, articulated hooking means, and a motorized system that adjusts the radial distance between these components to accommodate different diameters, allowing for adaptable gripping and insertion of packing sections into cylindrical shells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-diameter insertion device is used, then the gripping mechanism is simple and robust, but it cannot accommodate packing sections of varying diameters (1m to 5m)
Solution Approach 1:
The gripping device employs a deployable modular structure with multiple uprights (main upright and peripheral uprights) that can be dynamically reconfigured. The radial distance between uprights is adjustable through deployment mechanisms, allowing the device to adapt its diameter to match packing sections ranging from 1m to 5m. This dynamic reconfiguration enables a single device to handle multiple diameter specifications without requiring separate fixed-diameter devices for each size.
Solution Approach 2:
The gripping device is divided into modular components including a main upright, multiple peripheral uprights, and detachable attachment means. Each peripheral upright can be independently positioned and adjusted, allowing the device to segment and reconfigure its structure according to the specific diameter requirements. This segmentation enables flexible adaptation while maintaining structural integrity through standardized connection interfaces.
2Reliability
If custom insertion devices are designed for each diameter, then optimal gripping performance is achieved, but manufacturing and operational costs increase significantly
Solution Approach 1:
The insertion device is designed as a universal platform capable of gripping and inserting packing sections across the full diameter range of 1m to 5m. The deployable modular structure with adjustable radial positioning allows a single device design to perform multiple diameter-specific functions. This multi-functionality eliminates the need to manufacture separate specialized devices for each diameter, significantly reducing manufacturing costs while maintaining reliable gripping performance through standardized attachment means.
3Adaptability or versatility
If the radial distance between uprights is fixed, then the structural stability is high, but the device cannot adjust to different packing section diameters
Solution Approach 1:
The radial distance between the main upright and peripheral uprights is made dynamically adjustable through deployment mechanisms. These mechanisms allow the structure to transition between different radial configurations while maintaining stability during each configured state. The attachment means are designed to provide firm gripping force once the desired radial distance is achieved, ensuring structural stability during the gripping and insertion operations for each specific diameter.
