Frustoconical Core Plug Assembly for Variable Adhesive Roll Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing adhesive roll mounting systems for contact cleaning systems face challenges in accommodating adhesive rolls of varying sizes due to limited spacing between core plugs, requiring complex and expensive mechanisms with multiple moving parts that are prone to failure.
Innovation Solution
A core plug assembly featuring frustoconical or cylindrical moveable and fixed core plugs, allowing translational and rotational movement along a common longitudinal axis, which increases spacing between the core plugs to accommodate adhesive rolls, and includes a gripping element for improved engagement, reducing the assembly's complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex mechanism with multiple moving parts is used to increase spacing between core plugs, then the spacing can be adjusted to accommodate adhesive rolls of varying sizes, but the device complexity increases and reliability decreases
Solution Approach 1:
The core plug assembly incorporates a moveable core plug that can translate along the longitudinal axis to adjust the spacing between core plugs. This dynamic adjustment allows the system to accommodate adhesive rolls of varying sizes without requiring complex multi-component mechanisms, thereby maintaining simplicity while achieving adaptability.
Solution Approach 2:
The system changes the positional parameter of the moveable core plug along the longitudinal axis to adjust the spacing between core plugs. By varying this single parameter (position of moveable core plug), the system can accommodate different adhesive roll sizes without increasing device complexity.
2Adaptability or versatility
If a mechanism with multiple moving parts is used to increase spacing between core plugs, then the spacing can be adjusted, but the reliability of the system decreases due to more potential failure points
Solution Approach 1:
The moveable core plug provides the necessary dynamic adjustment capability with a single moving component rather than multiple interconnected parts. This reduces the number of potential failure points while maintaining the ability to adjust spacing for different adhesive roll sizes, thereby improving reliability.
Solution Approach 2:
The invention extracts the essential function of spacing adjustment from a complex multi-component mechanism and implements it through a single moveable core plug. By removing unnecessary components, the system achieves the required adaptability with fewer moving parts, thus enhancing reliability.
3Adaptability or versatility
If the spacing between core plugs is increased to accommodate larger adhesive rolls, then the assembly's footprint increases, but the ability to accommodate varying roll sizes is improved
Solution Approach 1:
The moveable core plug enables dynamic adjustment of spacing between core plugs, allowing the assembly to accommodate adhesive rolls of different sizes without requiring a permanently increased footprint. The compact design is maintained when smaller rolls are used, while larger rolls can be accommodated by extending the spacing through movement of the core plug.
