Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening sets for mounting sanitary objects like cisterns and toilet bowls have limited adjustment range and require tools for assembly, making them costly and difficult to use.
Innovation Solution
A fastening set with a plug-in part that locks the connecting part to the mounting frame without tools, allowing for easy and quick assembly, and featuring a cap or plug design for axial securing and injury protection, with projections for precise positioning and increased adjustment range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fastening sets are used with tool-based assembly, then reliable axial locking is achieved, but assembly becomes complex and time-consuming
Solution Approach 1:
The plug-in part is designed to automatically lock the connecting part to the mounting frame through its own structural features (protrusions engaging with recesses) without requiring external tools or additional locking operations. The component serves itself by incorporating the locking function directly into the insertion mechanism.
Solution Approach 2:
The fastening set is divided into separate functional components: the plug-in part for locking, the connecting part for attachment, and the mounting frame. This segmentation allows each component to be optimized for its specific function and enables simple tool-free assembly by inserting the plug-in part into the connecting part.
2Ease of manufacture
If integrated locking mechanisms are used in connecting parts, then manufacturing cost increases, but separate plug-in parts add complexity
Solution Approach 1:
The plug-in part acts as an intermediary component that simplifies the overall structure by providing a dedicated locking function. Rather than complicating the connecting part with integrated locking mechanisms, the separate plug-in part serves as a mediator that achieves locking through simple geometric engagement between protrusions and recesses.
Solution Approach 2:
The plug-in part is designed as a simple, inexpensive component that can be easily manufactured from plastic or metal. Its simplicity allows for cost-effective production while maintaining reliable locking function, making it economically advantageous despite being a separate component.
3Adaptability or versatility
If adjustable mounting depth is implemented, then adaptability improves, but adjustment range becomes limited in traditional designs
Solution Approach 1:
The connecting part is designed with dynamic adjustment capability, allowing the mounting depth to be varied within a range. The plug-in part can be inserted at different positions along the connecting part's length, enabling continuous adjustment of the mounting frame's position to adapt to different wall thicknesses and mounting requirements.

AI summary
The invention relates to a fastening set for attaching a mounting frame for sanitary fixtures, in particular for a cistern, a toilet bowl and/or a washbasin, to a building wall, wherein the mounting frame is formed from hollow profile rods (2), with a connecting part (5) detachably connected to the mounting frame, which has a radially projecting connecting section (5.1), with a connecting rod (4) which is mounted in the connecting part (5), with a fastening part (3) attached to one end of the connecting rod (4) which can be fastened to a building wall, and with a plug-in part (7). In order for such a fastening set to be manufactured cost-effectively and to offer simple and quick assembly without tools, the invention provides that the plug-in part (7) is inserted into an opening (2) for axially fixing the connecting part (5) to the mounting frame.6) can be used in a hollow profile bar (2) of the mounting frame and, when assembled, locks the connecting part (5) and the hollow profile bar (2) to each other.
