Modular Support Frame for Fiber Web Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fiber web machine frame structures require significant design effort and are not standardized, making them complex and inefficient to adapt to specific projects, particularly in the forming section where endless loop fabrics need frequent changes.
Innovation Solution
A support frame structure with modular columns and standardized attachment interfaces allows for the construction of a simpler, more versatile frame system, where columns can be easily connected and disconnected, and beams and girders are integrated between columns without cantilever beams, facilitating the use of endless loop fabrics and enabling preassembly and easy assembly on-site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional separate design for each fiber web machine frame is used, then the frame can be customized for specific project requirements, but the design complexity and time consumption increase significantly
Solution Approach 1:
The frame structure is divided into modular components: columns with standardized attachment interfaces, beams, and girders that can be independently selected and assembled. This segmentation allows customization through component selection rather than custom design, reducing overall design complexity while maintaining adaptability.
Solution Approach 2:
Standardized attachment interfaces are designed to be universal across all columns, beams, and girders in the system. These interfaces can accommodate different configurations and project requirements through standardized connection methods, eliminating the need for custom designs while maintaining versatility.
2Ease of manufacture
If columns are made as single integrated parts, then the structure is simpler to manufacture, but the ability to create cut-outs for fabric insertion becomes limited
Solution Approach 1:
Columns are divided into multiple separable parts that can be assembled together. This segmentation allows cut-outs to be created at the junction points between parts, enabling fabric insertion while keeping each individual column part simple to manufacture without complex cut-outs.
Solution Approach 2:
The column parts are pre-designed with standardized attachment interfaces that include provisions for fabric insertion. This preliminary design allows the cut-outs to be integrated into the manufacturing process of standard parts, maintaining manufacturing simplicity while ensuring fabric insertion capability is built-in.
3Adaptability or versatility
If detachable portions are added to columns to create cut-outs, then fabric insertion becomes possible, but the column structure becomes more complex
Solution Approach 1:
Instead of adding detachable portions to an otherwise solid column, the column is fundamentally segmented into multiple parts from the design stage. This segmentation creates natural separation points for fabric insertion without requiring additional complex mechanisms.
Solution Approach 2:
The segmented column design with standardized interfaces serves multiple functions: structural support, easy assembly/disassembly, and fabric insertion capability. This multi-functionality is achieved through the basic segmented structure itself rather than adding separate mechanisms, avoiding increased complexity.
4Length of stationary object
If cantilever beams are used to support the driving side, then the frame can be extended, but the structure requires additional support members and becomes more complex
Solution Approach 1:
The standardized attachment interfaces on columns are designed to accommodate both cantilever beams and regularly supported beams using the same connection mechanism. This universality allows frame extension through cantilever beams without requiring special support members or complex additional structures.
