Water Closet Removable Cap for Debris Prevention and Pressure Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water closet assemblies lack a convenient and effective method to prevent debris from entering drainage pipes and facilitate pressure testing without compromising the integrity of the system.
Innovation Solution
A water closet assembly with a removable cap that includes an annular shear wall, which can be pierced and separated using a suitable instrument, allowing for the cap's removal after installation, thereby preventing debris entry and enabling pressure testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a permanent cap is used to cover the drainage pipe opening, then debris prevention is effective, but the cap cannot be removed for pressure testing
Solution Approach 1:
The cap is segmented into two parts: a permanent outer cap that remains on the drainage pipe to prevent debris entry, and a removable inner cap that can be taken off to allow pressure testing. This segmentation allows each part to fulfill its specific function independently, resolving the contradiction between debris prevention and pressure testing capability.
Solution Approach 2:
The cap transitions from a static permanent structure to a dynamic system where the inner cap can be moved (removed) when needed for pressure testing, then replaced to restore debris prevention. This dynamic capability allows the system to adapt between different operational states.
2Ease of operation
If the cap is made easily removable, then pressure testing is facilitated, but the installation integrity may be compromised
Solution Approach 1:
The cap is divided into permanent and removable portions, where only the inner cap is designed for easy removal. This segmentation allows the outer cap to maintain installation integrity while the inner cap provides ease of operation for pressure testing.
Solution Approach 2:
The removable functionality is extracted as a separate inner cap component, allowing it to be easily removed for pressure testing without affecting the permanent outer cap that maintains installation integrity. The essential function of easy removal is isolated to a specific component.
3Ease of manufacture
If a traditional flange without cap is used, then installation is simple, but debris can enter the drainage pipe
Solution Approach 1:
The cap is merged with the flange assembly, combining the debris prevention function with the existing simple flange structure. This integration adds debris protection without significantly complicating the installation process, as the cap is installed as part of the standard flange mounting procedure.
