Drain Seal Groove Layout for Stable Odor Trap Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage devices face challenges in flexibility and reliability due to issues with rubber ring movement during insertion and adjustment, which affects sealing and prevents subsequent odor trap displacement.
Innovation Solution
A drainage device featuring a drain rail with a substructure frame and a groove on the drain body, allowing for lateral compensation and accommodating an odor trap insert with a removable frame, ensuring the sealing means are not touched during nozzle insertion or odor trap removal, thus enhancing adaptability and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rubber ring is inserted into the drainage opening and held by the drainage nozzle, then the sealing function is achieved, but the rubber ring can be displaced during installation and adjustment, resulting in loss of sealing effect
Solution Approach 1:
The sealing ring is extracted from the drainage opening and positioned in a groove on the drain body instead. This separation allows the sealing ring to be securely held in the groove during installation and adjustment, preventing displacement while maintaining the sealing function when the drain outlet is inserted.
Solution Approach 2:
The sealing system is segmented into two parts: the sealing ring positioned in the groove on the drain body, and the drainage opening in the drain rail. This segmentation allows independent positioning and securing of the sealing ring, improving installation stability while preserving sealing reliability.
2Reliability
If the rubber ring is positioned inside the drainage opening, then sealing is achieved, but subsequent relocation of odor traps installed in the drain opening is not possible
Solution Approach 1:
The sealing ring is taken out from the drainage opening and repositioned in the groove on the drain body. This extraction creates clear spatial separation between the sealing function and the odor trap installation area, allowing odor traps to be freely installed, removed, and relocated in the drain opening without affecting the sealing ring's position or function.
3Reliability
If the seal carrier is positioned inside the opening, then sealing is provided, but the sealant is touched and potentially compromised during insertion of nozzle and odor trap
Solution Approach 1:
The seal carrier with the sealing ring is extracted from the drainage opening and positioned in the groove on the drain body. This spatial separation ensures that during installation operations such as inserting the drain outlet or odor traps into the opening, the sealing ring remains undisturbed in its protected position, maintaining sealing reliability while facilitating ease of installation.
