Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for supplying or removing media to rotating machine components inefficiently utilize the rotor cross-section, requiring increased rotor diameter for high media throughput, leading to material waste and increased wear on sealing parts.
Innovation Solution
The use of circular section-shaped connecting lines that cover the full 360° of the rotor, allowing for a reduced rotor diameter while maintaining the same effective cross-sectional area, along with adaptive partition wall thickness and sector angle adjustments based on media volume, and a transition piece for compatibility with conventional components.

Engineering Contradiction Analysis
1Productivity
If the rotor diameter is increased to provide connecting lines with maximum cross-sectional area for high media throughput, then the media throughput is improved, but the material consumption and wear on sealing parts increase
Solution Approach 1:
The patent transitions from conventional circular connecting lines to circular section-shaped connecting lines that utilize the radial dimension of the rotor more effectively. By arranging connecting lines in a circular section pattern radiating from the rotor center, the design maximizes the use of available rotor cross-sectional area without increasing rotor diameter, thereby maintaining high media throughput while reducing material consumption.
Solution Approach 2:
The patent changes the geometric parameters of the connecting lines from standard circular cross-sections to circular sections with optimized sector angles and radial arrangements. This parameter optimization allows the same or greater effective cross-sectional area for media flow within a smaller rotor diameter, reducing both material consumption and sealing surface wear.
2Productivity
If the rotor diameter is increased to provide connecting lines with maximum cross-sectional area for high media throughput, then the media throughput is improved, but the wear on sealing parts increases
Solution Approach 1:
By implementing circular section-shaped connecting lines that radiate radially from the rotor center, the patent optimizes the spatial arrangement of media channels. This radial circular section configuration allows efficient media throughput without increasing rotor diameter, thereby reducing the peripheral speed and corresponding wear on sealing parts while maintaining high productivity.
Solution Approach 2:
The patent optimizes the geometric parameters of connecting lines including sector angles and radial positions to maximize flow efficiency within a compact rotor design. This parameter optimization reduces the required rotor diameter and peripheral speed, directly reducing wear on sealing parts while maintaining high media throughput.
3Ease of manufacture
If conventional circular connecting lines are used, then the design is simple, but the rotor cross-sectional area is not optimally utilized
Solution Approach 1:
The patent introduces a radial circular section arrangement of connecting lines that better utilizes the rotor's cross-sectional area. By organizing media channels in a radial pattern from the rotor center, the design achieves more efficient space utilization compared to conventional circular lines, while the modular nature of the circular section design maintains manufacturing simplicity.

AI summary
The device has a rotor (2) arranged in and rotatable with respect to a sealing head housing (1), whereby the housing and rotor have feed and outlet openings (4,5) for the medium or media that connect connecting lines (3) within the rotor to an annular space (7-9) between the sealing head housing and the rotor. At least one seal (6) seals the rotor with respect to the housing. The connecting lines are circle sector-shaped in cross-section, whereby the radial wall surfaces of two adjacent connecting lines form a dividing wall of homogeneous thickness between them.
