Wedge Clamping Mounting Device for Sanitary Fixtures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting systems for sanitary items like toilets, bidets, and washbasins on vertical walls require adequate access for nut positioning and tightening, which can be cumbersome due to the need for tools with sufficient freedom of movement, and often rely on external threads that may not provide secure fixation against horizontal forces.
Innovation Solution
A mounting device combining a form-fitting element with a wedge clamping mechanism that secures the sanitary item to a rod protruding from the wall, allowing for a form-fit connection that prevents removal by horizontal force without the need for rotating nuts, using a wedge clamping mechanism that can be actuated externally, and optionally incorporating a securing element with spring force for additional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If externally threaded rods are used for mounting sanitary items, then the mounting system is simple and widely applicable, but adequate access for nut positioning and tightening is required which can be cumbersome
Solution Approach 1:
The nut is extracted from the mounting mechanism and replaced by a wedge clamping element that integrates the fastening function directly into the mounting rod system, eliminating the need for separate nuts and tool access
Solution Approach 2:
Instead of screwing nuts onto external threads to create clamping force, the invention uses a wedge-shaped element that converts lateral insertion force into axial clamping force through the wedge angle, inverting the traditional screw-mechanism approach
2Ease of manufacture
If externally threaded rods with nuts are used, then mounting is achievable, but secure fixation against horizontal forces is not reliably provided
Solution Approach 1:
The wedge clamping element is inserted laterally into the mounting rod before the sanitary item is fully positioned, creating preliminary form-fit connection that guides and secures the item against horizontal forces during the mounting process
Solution Approach 2:
The mounting system combines the form-fit connection of the wedge element with the friction grip of the threaded rod, creating a composite fastening mechanism that provides both positional accuracy and force resistance
3Reliability
If a wedge clamping mechanism is introduced to improve clamping force, then secure fixation is achieved, but device complexity increases
Solution Approach 1:
The wedge clamping element is merged with the mounting rod structure, where the wedge element serves as both the fastening component and the clamping mechanism, eliminating the need for separate nuts, washers, and multiple fastening steps
Solution Approach 2:
The wedge clamping mechanism is designed to be self-actuating through lateral insertion, where the wedge angle automatically converts the insertion force into axial clamping force without requiring external tools or additional operational steps
