Modular Floor Drain with Removable Inclined Molded Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor drain devices require complex and costly production, and are inflexible in adapting to local conditions or design requirements, especially when multiple gradient areas are needed in shower installations.
Innovation Solution
A modular device comprising a molded part and a receptacle, where the molded part can be easily inserted, removed, or adjusted, allowing for variable configuration and design changes, with options for different materials and gradients to simplify installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a one-piece molded part with multi-slope contour is used, then the gradient areas are formed, but the production cost increases and adaptability decreases
Solution Approach 1:
The device is divided into separate components: a base body and a molded part that can be produced independently and assembled together. This segmentation allows each component to be manufactured using simpler, less expensive processes while maintaining the overall gradient functionality when assembled.
2Manufacturing precision
If a one-piece molded part with multi-slope contour is used, then the gradient areas are formed, but the adaptability to local conditions decreases
Solution Approach 1:
The molded part is designed to be removable and replaceable, allowing the gradient configuration to be dynamically adjusted or adapted to different local conditions and design requirements. This enables flexibility in installation locations and configuration modifications without requiring custom one-piece components for each scenario.
3Reliability
If multiple gradient areas are created in screed or shower tray, then the drain function is achieved, but the manual or mechanical effort increases
Solution Approach 1:
The gradient areas are pre-formed on the molded part during its manufacturing process, rather than requiring manual or mechanical creation of multiple gradient zones during installation. This preliminary formation of gradients significantly reduces the labor and mechanical effort required during installation while ensuring reliable drainage function.
4Stability of the object's composition
If the molded part is firmly connected to the receptacle, then the structural stability increases, but the ease of cleaning and replacement decreases
Solution Approach 1:
The connection between the molded part and receptacle is designed to be dynamically adjustable - firmly connected during normal use to maintain structural stability, but easily separable when cleaning or replacement is needed. This dynamic connection state allows the system to switch between stability and ease of maintenance as required.
