Sanitary Fastening Device with Tilting Holding Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for sanitary objects, such as washbasins and toilets, are difficult to assemble and disassemble efficiently, and pose a risk of the object falling during disassembly, often requiring multiple people for larger objects.
Innovation Solution
A fastening device with a movable holding element that can transition between locking and release positions, allowing for easy assembly and disassembly without requiring the base body to be rotated relative to the threaded rod, and featuring an actuating lever for manual operation and a washer to prevent unintended release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a nut and base body are unscrewed for disassembly, then the sanitary object can be detached, but the process requires time and multiple people to secure the object against falling
Solution Approach 1:
The holding element is designed to be movable between a locking position (where it engages the threaded rod) and a release position (where it disengages). This dynamic mechanism allows quick transition from locked to unlocked state by simply moving the holding element, eliminating the time-consuming unscrewing process while maintaining secure attachment during normal use
Solution Approach 2:
The invention extracts the base body from the disassembly process. Instead of requiring the base body to be unscrewed, only the holding element needs to be moved to the release position, allowing the threaded rod to be freely removed while the base body remains in place, significantly reducing disassembly time and complexity
2Ease of operation
If the holding element is held tilted during disassembly to pull out the threaded rod, then the rod can be removed, but the mechanism requires the holding element to be tilted quite far and the rod to be pushed a relatively large distance
Solution Approach 1:
The holding element is pre-configured with a tiltable geometry that automatically creates clearance between the threaded rod and the receiving channel wall when tilted. This preliminary geometric arrangement ensures that once the holding element is tilted to the release position, the threaded rod can be easily pulled out without requiring large pushing distances or complex manual manipulation
3Reliability
If the holding element is spring-loaded to automatically return to locked position, then the rod can be securely held, but the holding element must be kept tilted during insertion to prevent premature engagement
Solution Approach 1:
The holding element utilizes spring-loaded dynamics to automatically transition from the tilted insertion position to the locked position. During insertion, the element is held tilted to prevent engagement; once the threaded rod is fully inserted, the spring automatically pushes the holding element into the locked position, providing secure attachment without requiring manual intervention to maintain the tilted state
Solution Approach 2:
The spring mechanism provides self-service by automatically returning the holding element to the locked position after insertion. The spring stores energy during the tilting phase and releases it to automatically engage the locking mechanism, eliminating the need for continuous manual control and ensuring reliable attachment without additional operational steps

AI summary
The invention relates to a fastening assembly (37), in which a sanitary object (38) is fastened by means of a fastening device (1). Movable retaining elements (18) for retaining a threaded rod (40) are arranged in a main body (2). Said retaining elements can be moved back and forth between a latching position and a release position. In order to prevent the retaining element (18) from being inadvertently moved into the release position, according to the invention the fastening device (1) is designed in such a way that a nut (44) and a washer (43) block movement of the retaining element (18) from the latching position into the release position in the fully assembled state.
