Spring-Expanded Wall Holder for Secure Sanitary Object Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall holders for wall-hung sanitary objects, such as toilet bowls, are difficult to manufacture and assemble stably and resiliently using standard tools, often requiring complex procedures and tools for secure attachment.
Innovation Solution
A wall holder design featuring a housing with a clamping device that expands via spring force, utilizing two clamping elements and an actuating element to securely fasten a threaded rod anchored in the wall, allowing for easy assembly and detachment using standard tools like a hexagonal wrench, with a snap-lock mechanism for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex clamping mechanism is used to ensure stable and resilient fixation, then the reliability of wall holder fixation is improved, but the ease of manufacture and assembly deteriorates
Solution Approach 1:
The wall holder is divided into distinct functional modules: a housing component, a clamping device with expandable clamping elements, and an actuating mechanism. This segmentation allows each component to be manufactured independently using standard processes and then assembled together, reducing overall manufacturing complexity while maintaining reliable fixation through the specialized clamping mechanism.
Solution Approach 2:
The clamping device is designed to be inserted into the housing cavity in a compressed state and then expand within the housing. The actuating element is nested within the housing and acts on the clamping device through the cavity. This nested arrangement consolidates multiple components into a compact structure that achieves reliable fixation without requiring complex external mounting mechanisms.
2Reliability
If a complex assembly procedure is used to achieve secure attachment, then the reliability of wall holder fixation is improved, but the productivity of installation deteriorates
Solution Approach 1:
The clamping device automatically expands upon insertion into the housing cavity, securing itself without requiring manual adjustment or additional fastening steps. The actuating element automatically transfers force to the clamping device when actuated, creating a self-contained installation process that achieves secure attachment quickly with minimal installer intervention.
Solution Approach 2:
The manual operation of tightening and securing the wall holder is replaced by a mechanical actuation system. The actuating element converts rotational or linear motion into controlled expansion of the clamping elements, providing consistent and reliable attachment security while significantly reducing installation time compared to traditional manual assembly methods.
3Reliability
If specialized tools are used to achieve robust fixation, then the reliability of wall holder fixation is improved, but the ease of operation deteriorates
Solution Approach 1:
The actuating element is designed to be operated with common, readily available tools such as hex keys or Allen wrenches, which are universally found in most toolkits. This universal compatibility allows installers to achieve robust fixation without requiring specialized or proprietary tools, thereby maintaining ease of operation while ensuring reliable and secure attachment of the wall holder.

AI summary
A wall bracket (2) for a wall-hung object, in particular a toilet bowl, wherein the wall bracket (2) comprises: - a housing (4) enclosing a cavity (8), - a clamping device (12) having two clamping elements (30, 32) that can be expanded by spring force, and - an actuating element (20) acting on the clamping device (12), wherein the clamping device (12) can be inserted into the cavity (8) in a compressed state along an insertion direction (22) through an insertion opening (10) and expands therein as a result of the spring force when the actuating element (20) is released, such that movement out of the cavity (8) is blocked, and wherein the clamping device (12) inserted into the cavity (8) can be compressed by the actuating element (20) such that a fastening rod (84) anchored at one fixed end in a wall and projecting at one free end into the cavity (8) is held in place by force and/or positive locking between the clamping elements (30,32) is fixed.,
