Shower Head Fixing Assembly With Built-In Wrench Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-way valves require a wrench for mounting and are prone to loosening due to their integral structure, causing inconvenience and shifting of the center of gravity, which leads to repeated tool usage and assembly challenges.
Innovation Solution
A multipurpose shower head fixing device with a connecting and fixing piece featuring a wrench structure and a shower head connecting mechanism that integrates a locking nut, allowing for tool-free assembly and disassembly, and preventing the shifting of the switching valve's center of gravity by using a bushing with limiting corners and a clamping flange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional three-way valve with integral structure is used, then the valve can be mounted, but it requires a wrench for mounting and is prone to loosening due to center shift
Solution Approach 1:
The device is divided into separate components: a switching valve body and a detachable shower head fixing assembly. The fixing assembly includes a connecting piece with wrench structure that can be independently attached and removed, allowing the valve body to remain simple while providing easy mounting capability through the separate fixing component.
Solution Approach 2:
The connecting piece serves multiple functions: it acts as a wrench for tightening the locking nut, provides a detachable fixing mechanism for the shower head, and maintains the valve's center of gravity stability. This multi-functional component eliminates the need for separate tools and prevents loosening issues.
2Reliability
If a wrench is used for mounting the three-way valve, then the valve can be secured, but the wrench is restricted in operation due to its large size and requires repeated use
Solution Approach 1:
The wrench function is merged into the connecting piece that is already part of the shower head fixing assembly. The limiting corners on the connecting piece form a wrench structure that can tighten the locking nut, combining the fixing function and the tightening function into a single integrated component, eliminating the need for a separate large wrench.
Solution Approach 2:
The connecting piece with wrench structure enables the user to tighten and loosen the locking nut using the same component that is already attached to the valve. The device serves itself by providing the tightening mechanism as part of its own structure, eliminating dependency on external tools.
3Device complexity
If the shower head holder is directly matched with the switching valve, then the assembly is simple, but the center of the valve shifts and causes loosening during use
Solution Approach 1:
The connecting piece acts as an intermediary component between the shower head holder and the switching valve body. It includes a locking nut that threads onto the valve body and limiting corners that prevent rotation, serving as a mediator that maintains proper alignment and prevents center shift while still allowing simple assembly.
