Roll-In Shower Base Insert Design for Water Spillage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Roll-in showers face challenges in preventing water from spilling over the curb due to safety regulations requiring a controlled vertical drop between the basin and the curb, which existing designs struggle to meet effectively.
Innovation Solution
A shower base with a sloping basin and a curb, combined with an insert that has a downward-sloping top surface, is designed to direct water towards a drain and prevent spillage, where the insert is secured along the threshold between the basin and the curb, with a slope of 1 to 2 or less to ensure compliance with safety regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a curb is added to prevent water spillage, then water containment is improved, but the vertical drop between basin and curb increases beyond safety thresholds
Solution Approach 1:
The curb structure is segmented into multiple components: the base curb, and an additional insert element that is separately installed. This segmentation allows the insert to be precisely positioned and sized to provide the necessary water containment without increasing the overall vertical drop beyond safety thresholds, thus resolving the contradiction between spill prevention and threshold compliance.
Solution Approach 2:
The insert acts as an intermediary element between the basin and the curb. It is installed along the threshold to provide additional water containment functionality without requiring an increase in the curb's vertical height. This intermediary component enables water spillage prevention while maintaining compliance with the maximum vertical drop requirement.
2Productivity
If the basin slopes toward the drain, then water drainage is improved, but water may spill over the curb before reaching the drain
Solution Approach 1:
The insert is installed locally at the threshold area where water spillage occurs, rather than modifying the entire basin structure. This localized intervention provides water containment precisely where needed, allowing the basin to maintain its sloping design for efficient drainage while preventing spillage at the critical threshold location.
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 effectively directs water towards the drain and prevents spillage while ensuring compliance with safety regulations by using a combination of a sloping basin, curb, and insert, enhancing the functionality and safety of roll-in showers.
Implementation Method 1
a basin that slopes toward a center of the shower base in order to direct water towards a drain
Implementation Method 2
The insert has a first top surface that slopes down from the curb and towards the basin

AI summary
A shower base is provided. The shower base includes a basin that slopes toward a center of the shower base in order to direct water towards a drain. The shower base also includes a curb that extends along a peripheral edge of the basin. The Curb has an elevation that rises above the basin in order to prevent water from spilling out of the basin. An insert is secured to the shower base and is disposed along a threshold between the basin and the curb on an ingress side of the shower base. The insert has a first top surface that slopes down from the curb and towards the basin.
