Sanitary Fastening Device with Movable 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, particularly requiring multiple people for larger objects, and pose a risk of the object falling during disassembly.
Innovation Solution
A fastening device with a movable holding element that can transition between locking and release positions, allowing for easy disassembly without tools, and a snap-on mechanism that enables secure attachment and detachment without rotating the base body relative to the threaded rod.
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 takes time and requires multiple people to prevent falling
Solution Approach 1:
The holding element is designed to be movable between a locking position (where it engages the thread) and a release position (where it disengages). This dynamic mechanism allows the fastening state to change from fixed to free, enabling quick release without unscrewing operations. The holding element can be actuated by a tool or manually to transition between positions, facilitating rapid disassembly by a single person.
2Ease of operation
If the holding element is tilted far and the threaded rod pushed a large distance, then the threaded rod can be pulled out, but the operation becomes complex and requires precise control
Solution Approach 1:
The extraction of the threaded rod is achieved by simply pulling it axially outward from the receiving channel. The holding element's design allows it to disengage automatically or with minimal action when the threaded rod is pulled, eliminating the need for complex tilting maneuvers or large push distances. The disassembly operation is reduced to a simple axial extraction motion.
3Ease of operation
If a tool is used to tilt the holding element, then the threaded rod can be removed, but an additional tool is required
Solution Approach 1:
The actuating lever serves multiple functions: it provides leverage to move the holding element from the locking position to the release position, and it can also serve as a handle for gripping the base body during assembly and disassembly operations. This multi-functionality reduces the need for separate specialized tools.
4Ease of manufacture
If the base body is made of plastic in one piece, then manufacturing is simplified, but the holding element must be precisely integrated
Solution Approach 1:
The holding element is designed as a separate component from the base body, allowing it to be manufactured independently with standard tolerances and then assembled into the base body. This segmentation reduces the manufacturing precision requirements for the base body itself, as the holding element can be produced separately and inserted into pre-formed receptacles or mounting features in the plastic base body.
