Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The application of fluids during the manufacturing process of magnetic storage devices is challenging due to difficulties in evenly distributing and supporting magnetic discs, which affects the efficiency and uniformity of treatments.
Innovation Solution
An apparatus with an elongated member featuring grooves and fluid release portions is used to support discs, allowing fluid to flow through an interior channel and radially distribute onto the discs, ensuring uniform application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If discs are held in place on a support during fluid distribution, then the discs can be supported and positioned, but the application of treatments and fluids becomes difficult
Solution Approach 1:
The support structure is segmented into multiple grooves along its length, with each groove configured to receive a portion of a disc. This segmentation allows fluid to be distributed to multiple discs simultaneously while maintaining individual control over fluid application to each disc position
Solution Approach 2:
The support structure incorporates porous material with controlled porosity (6-60%) that allows fluid to pass through from the interior channel to the exterior surface. This porous design enables efficient fluid distribution while maintaining structural integrity and disc positioning
2Manufacturing precision
If fluid is distributed through an interior channel, then uniform fluid application can be achieved, but the structure becomes more complex
Solution Approach 1:
The interior channel serves multiple functions: it provides structural support for the elongated member, enables fluid distribution to multiple discs simultaneously, and maintains precise positioning of the disc portions. This multi-functionality reduces the need for additional separate components
Solution Approach 2:
The support structure features localized variations in porosity along its length, with different sections having different porosity levels to optimize fluid distribution to specific disc positions. This local quality control ensures uniform fluid application while managing structural complexity
