Continuous Service Platform for Fiber Web Machine Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing service platforms in fiber web machines are inefficiently designed, requiring separate platforms for each process section, making it cumbersome for personnel to move between components and necessitating accurate positioning of railings, which is time-consuming and prone to errors.
Innovation Solution
A service platform arrangement with a continuous walkway and railing system extending along multiple machine sections at the same horizontal level, positioned to minimize the need for stairs and ensure safe, efficient access to various sections, including the forming and press sections, with railings aligned at a consistent distance from the machine center line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate service platforms are provided for each process section, then access to various components is ensured, but moving between partial processes becomes cumbersome and setup time increases
Solution Approach 1:
The patent combines multiple separate service platforms into a single continuous service platform that spans across multiple process sections (forming section, press section, drying section). This merging eliminates the need for separate platforms for each section, allowing personnel to move continuously across all sections without interruption, thereby reducing setup time while maintaining comprehensive access.
Solution Approach 2:
The continuous service platform serves multiple functions simultaneously: it provides access to the forming section, press section, and drying section, while also supporting railing installation and personnel movement across all sections. This multi-functional design replaces what would otherwise require multiple separate platforms, reducing overall setup time.
2Reliability
If traditional railing positioning is used with sleeves in service platforms, then sturdy and reliable structure is achieved, but great accuracy in positioning is required and construction becomes inefficient
Solution Approach 1:
The patent replaces the static, fixed-positioning railing system (requiring precise sleeve positioning) with a dynamic adjustment system. The railing height and position can be adjusted along the service platform using movable support mechanisms, allowing installation without precise pre-positioning of sleeves or holes, thereby significantly improving construction efficiency while maintaining structural reliability.
Solution Approach 2:
The invention changes the positioning parameter from fixed (requiring exact sleeve-pole alignment) to adjustable (allowing movement along the service platform). This parameter change enables the railing to be positioned at various heights and locations without requiring great accuracy in initial positioning, simplifying construction while maintaining the sturdy structure through adjustable support mechanisms.
