Bathtub Drainage Assembly Guide Member Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bathtub drainage assemblies face alignment issues due to the lack of proper support for the drain pipe, making it difficult to connect the stopper unit to the tub shoe, resulting in inefficient installation and alignment.
Innovation Solution
A guide member is introduced, which is detachably hooked to the drain pipe to align the stopper unit and tub shoe, featuring a rod with different connection portions to securely connect the outer threads of the base with the inner threads of the tub shoe, ensuring precise alignment and support during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drain pipe is not supported during installation, then the installation process is simpler, but the alignment between the tub shoe and base becomes difficult
Solution Approach 1:
A guide member is introduced as an intermediary tool during installation. The guide member includes a guide portion that fits into the drain pipe and a connection portion that attaches to the base, serving as a temporary mediator to align and support the drain pipe during the connection process. After installation, the guide member is removed.
2Ease of manufacture
If the drain pipe is elongate and not well supported, then the device structure is simpler, but the connection between outer threads and inner threads becomes inconvenient
Solution Approach 1:
The guide member is installed on the drain pipe before the connection process begins. The guide portion is inserted into the elongate drain pipe to provide preliminary support and positioning, ensuring the drain pipe is properly aligned and stable before the threading connection is made between the base and tub shoe.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The guide member facilitates easy, precise, and effective connection between the drain pipe and the base, reducing installation time and ensuring proper alignment, thus improving the overall efficiency of the drainage assembly.
Implementation Method 1
The resilient plate 16 is deformed to store an energy. On the contrary, when pushing the cover 11 again, the energy of the resilient plate 16 is released to push the stopper 13 to move upward

AI summary
A drainage assembly for a bathtub includes a stopper unit having a base including a drain passage and a lock hole defined through a bottom thereof. A drain pipe includes a tub shoe at one end thereof and the tub shoe communicates with the drain passage. An extension extends from the inner bottom of the tub shoe. A guide member includes a rod which includes a first connection portion formed on the first end of the rod, and a hook formed on the second end of the rod. The first connection portion is detachably connected to the extension to extend the rod through the lock hole so as to align the tub shoe with the base, and to connect the outer threads of the base with the inner threads of the tub shoe easily.
