Filling Disk Non-Circular Through-Hole Anchor Gap Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filling discs with circular through-holes can block the flow of hardenable mass around anchors due to their design, particularly with smooth-walled sleeve anchors, preventing effective filling of the annular gap between the anchor and the attachment.
Innovation Solution
A non-circular through-hole with a smallest cross-section and radially inward protruding spacers ensures a gap for the hardenable mass to flow circumferentially, preventing blockage even when the disc rests against the anchor, and an inclined filling opening facilitates easy access for filling nozzles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a circular through-hole is used in the filling disc, then the disc can rest flat on the anchor circumference, but the hardenable mass flow is blocked when the inner wall contacts the anchor
Solution Approach 1:
The through-hole is designed with a non-circular cross-section (oval, rectangular, or triangular) instead of circular. This asymmetric shape ensures that the inner wall of the through-hole cannot make complete contact with the anchor circumference, maintaining gaps that allow hardenable mass to flow circumferentially around the anchor even when the filling disc rests flat on the anchor.
2Reliability
If the through-hole cross-section is reduced to ensure gap formation, then mass flow is enabled, but the structural strength of the filling disc is reduced
Solution Approach 1:
The filling disc exhibits different cross-sectional properties at different locations. The through-hole has a non-circular cross-section with reduced area only in specific regions where gaps are needed for mass flow, while other portions of the disc maintain full structural integrity. This localized modification ensures mass flow capability without compromising overall disc strength.
3Reliability
If a non-circular through-hole is used, then gaps are ensured for mass flow, but the manufacturing complexity increases
Solution Approach 1:
The through-hole is designed with simple non-circular geometries such as oval, rectangular, or triangular cross-sections. These asymmetric shapes can be manufactured using standard drilling and shaping techniques, making them practically feasible despite the increased complexity compared to circular holes. The geometric simplicity of these shapes balances the need for gap formation with manufacturing ease.

Function Achieved in This Case
Ensures reliable flow of hardenable mass into the annular gap between the anchor and attachment, ensuring secure fastening without play in the radial direction, even with smooth-walled anchors, and allows for efficient filling of the annular gap, enhancing the attachment's stability under dynamic loads.
Implementation Method 1
a fluid, for example pasty, hardenable mass is filled under pressure through the filling opening of the filling disc
Implementation Method 2
After the mass has hardened, the add-on part is fixed radially on the anchor

AI summary
The invention relates to a filling disk (1) for an armature (11, 12) and proposes to form a through-hole (2) of the filling disk (1) in the shape of a circular saw blade. In this way, it is ensured that a contact of the filling disk (1) on the armature (11, 12) does not block a filling channel for a hardenable mass.
