Transparent Filling Aid for Slot Recess Shear Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filling systems for slot-like recesses are costly and difficult to install, and they do not effectively secure attachments against lateral forces, which can cause displacement due to insufficient frictional resistance.
Innovation Solution
A filling system comprising a filling disc and a filling aid that encloses the disc, allowing a flowable, hardenable compound to be introduced into the recess, with a configuration that includes a first and second sealing surface to prevent the compound from escaping and secure the attachment to the substrate, featuring a rotatable and spring-like connection for easy assembly and complete coverage of the recess.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional filling system is used for slot-like recesses, then the attachment can be fastened to the substrate, but the system is costly and difficult to install
Solution Approach 1:
The filling system is divided into two separate components: a filling element that is integrated with the fastening element and a filling aid that is applied separately. This segmentation allows for simpler manufacturing and assembly of each individual component, while maintaining the overall functionality of securing the attachment to the substrate.
Solution Approach 2:
The filling aid acts as an intermediary component between the filling element and the slot-like recess. It is applied to the filling element and then inserted into the recess, facilitating the filling process and ensuring proper positioning without requiring complex integrated systems.
2Reliability
If a conventional filling system is used for slot-like recesses, then the attachment can be fastened to the substrate, but the system is costly
Solution Approach 1:
By separating the filling system into a filling element and a filling aid, each component can be manufactured using simpler and more cost-effective processes. The filling element can be produced as a standard fastening component, while the filling aid can be manufactured as a separate, simpler component, reducing overall manufacturing costs.
Solution Approach 2:
The filling aid is designed as a disposable component that is applied once and then discarded after the filling process. This eliminates the need for expensive, reusable complex filling systems, significantly reducing manufacturing and installation costs while maintaining secure attachment.
3Productivity
If the elongated recess is not filled, then the attachment can be installed quickly, but the attachment is not secured against displacement under shear forces
Solution Approach 1:
The filling element is integrated with the fastening element, allowing the filling material to be automatically applied and positioned during the fastening process. This self-service mechanism ensures that the recess is properly filled without requiring separate manual filling operations, maintaining both installation speed and shear force resistance.
Solution Approach 2:
The filling aid changes the physical state of the filling material by providing containment and pressure during insertion. This parameter change ensures the material properly fills the recess and cures to provide the necessary resistance to shear forces, while the process remains quick and efficient.
4Reliability
If a filling system with complete coverage is used, then the recess is fully secured, but the assembly becomes complex
Solution Approach 1:
The filling system is segmented into a filling element and a filling aid, where the filling aid is a simple applicator component that does not require complex assembly. This segmentation achieves complete coverage of the recess while keeping the overall assembly process simple and straightforward.
Solution Approach 2:
The filling aid serves as a simple intermediary tool that facilitates complete filling of the recess without requiring complex mechanisms. It is applied, positioned, and removed in a simple sequence, achieving reliable coverage while minimizing assembly complexity.

AI summary
The invention relates to a filling system (3) for filling a slot-like recess (5) with a flowable, curable compound (18). The filling system (3) has a filling aid (6) and a filling element (7), in particular a filling disk (8). The filling aid (6) is mounted for rotation on the filling element (7) to ensure optimal positioning of the filling aid (6) with respect to the slot-like recess (5). Furthermore, the filling process of the slot-like recess (5) can be observed and checked at any time because of the transparent design of the filling aid (6).
