Solution Overview
Problem
Existing shower drain units are complex to assemble, prone to misalignment under high water pressure, and often result in inefficient water flow and odor issues due to their intricate designs and poorly secured components.
Innovation Solution
A drain unit comprising a sump, a siphon housed within the sump, and a grid with C-shaped slits that directs water efficiently through a curved surface, ensuring effective coupling with the building's drain system and easy assembly, while maintaining a sleek appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a complex sump shape with vertical walls and multiple unions is used, then water drainage capability is improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The drain unit is divided into separate functional components: a sump for water collection, a siphon for odor prevention and drainage, and a grid for filtration. Each component can be manufactured independently and assembled together, simplifying the overall device complexity while maintaining effective water drainage capability through the coordinated function of these segmented parts.
Solution Approach 2:
The siphon is nested within the sump structure, with the siphon housing positioned inside the sump. This nested arrangement allows the siphon to utilize the space within the sump, eliminating the need for separate complex external structures while maintaining both water drainage and odor prevention functions in a compact integrated design.
2Ease of manufacture
If the siphon is not well fastened to the sump, then assembly simplicity is improved, but reliability deteriorates under high water pressure
Solution Approach 1:
The siphon is pre-positioned within the sump during manufacturing, with its opening aligned with the bottom of the sump before final assembly. This preliminary positioning ensures that when the components are assembled in the field, the siphon is already correctly located and secured, maintaining reliability under high water pressure while keeping the assembly process simple.
3Productivity
If a grid with C-shaped slits is used, then water flow efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The grid features C-shaped slits with a specific local geometry designed to optimize water flow through the grid while maintaining structural integrity. The C-shape provides sufficient opening area for efficient drainage while the configuration is simple enough to be manufactured with standard precision tolerances, avoiding the need for excessively tight manufacturing specifications.
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 solution provides a straightforward assembly process, efficient water flow, and prevents unpleasant odors by optimizing the internal space and secure coupling of components, ensuring continuous and odor-free drainage.
Implementation Method 1
the siphon comprises a rear wall, an intermediate wall and a front wall, wherein the intermediate wall has a curved surface suitable for conveying the drain water into a union of the siphon
Implementation Method 2
the drain water flows down into the sump through the grid, then rises into the siphon between the rear wall and the back of the intermediate wall, and finally flows down along the curved surface towards the union of the siphon
Implementation Method 3
a grid suitable for filtering the drain water conveyed by the channel at the entrance of the sump
