Modular Installation Module for Paper Machine Hydraulic Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The equipping and maintenance of the driving side in paper or board machines are complex and resource-intensive due to the scattered positioning of components and pipes, which are typically installed after the machine frame is erected, leading to increased costs and scheduling limitations.
Innovation Solution
An installation module that can be pre-assembled and installed before or during the erection of the machine frame, featuring modular connections for pipes and valves, allowing centralized maintenance and flexible positioning to reduce the complexity and cost of equipment installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components and pipes are positioned on separate cabinets or large areas after frame erection, then the machine can be equipped with standard components, but the equipping becomes expensive and resource-intensive with limited scheduling flexibility
Solution Approach 1:
The patent divides the equipping into modular installation modules that can be independently assembled and positioned. Each module contains specific components and pipes grouped together, allowing flexible placement on the driving side without requiring scattered cabinet installations. This segmentation enables the system to be equipped in standardized units rather than custom-assembled components.
Solution Approach 2:
The installation modules are designed to be pre-assembled with components and pipes before being installed on the machine frame. Field pipes are routed through predetermined paths in the floor, and modules are prepared in advance with all necessary connections and actuators, enabling equipping to begin before frame erection is complete and reducing on-site assembly complexity.
2Loss of time
If pipes are designed after frame design in a hurry, then the project schedule can be maintained, but the equipping becomes expensive and binding of resources increases
Solution Approach 1:
The installation modules are designed and pre-assembled before frame erection, allowing thorough planning and optimization of pipe routes and component placement. Field pipe openings are predetermined in the floor design, and module configurations are finalized in advance, eliminating the need for hurried design adjustments after frame construction and reducing both time and cost.
Solution Approach 2:
The installation modules are designed as universal, standardized units that can be applied across different machine configurations. The modules incorporate multi-functional components and standardized pipe connections that can accommodate various equipping requirements without requiring custom design work, thereby reducing both development time and manufacturing costs.
3Ease of operation
If components are scattered positioned on the driving side, then the machine can be equipped with necessary components, but the maintainability becomes complicated
Solution Approach 1:
Components are grouped into discrete installation modules rather than being scattered across separate cabinets. Each module is a self-contained unit with all necessary components and pipes integrated, making it easy to isolate, remove, and replace specific modules for maintenance without affecting other parts of the system.
Solution Approach 2:
Maintenance access is pre-planned with dedicated spaces and routing paths for pipes and wiring within each module. The modular design allows maintenance personnel to access specific modules independently, and the standardized interfaces enable quick swapping of modules without complex disassembly of scattered components.
