Dual Odor Trap Urinal for Odor-Free Seal Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urinal odor trap replacement methods often generate unpleasant odors, especially in large facilities, as multiple traps need to be removed and replaced sequentially, leading to prolonged odor emission.
Innovation Solution
A method and urinal design where an additional odor trap is connected in series with the existing one, allowing for automatic closure and opening to prevent gas escape during replacement, enabling immediate reuse of the urinal and simplifying the replacement process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple odor traps are removed and replaced sequentially in large facilities, then the replacement process can be completed, but unpleasant odors are generated for extended periods
Solution Approach 1:
The system divides the odor trap replacement process into independent segments by providing multiple replaceable odor traps (first odor trap and second odor trap) that can be replaced separately and sequentially without affecting the entire system's functionality, allowing continuous operation while maintaining odor prevention
Solution Approach 2:
The second odor trap acts as an intermediary backup during the replacement of the first odor trap. When the first odor trap is removed, the second odor trap remains in place to continue blocking odors from the drain line, serving as a temporary mediator until the replacement is complete
2Ease of manufacture
If odor traps are replaced one at a time in large facilities, then the replacement can be managed, but the facility must be closed for extended periods
Solution Approach 1:
The system segments the odor trap functionality into multiple independent units (first and second odor traps) that can be replaced in succession. This segmentation allows the facility to remain operational throughout the replacement process, minimizing downtime and loss of time
Solution Approach 2:
The second odor trap is pre-installed and positioned to take over the odor-blocking function before the first odor trap is removed. This preliminary arrangement ensures continuous odor prevention capability, allowing immediate facility reopening after replacement
3Object-generated harmful factors
If an additional odor trap is added to the system, then odor prevention during replacement is improved, but device complexity increases
Solution Approach 1:
Both the first and second odor traps perform the same universal function of blocking odors from the drain line. This multi-functionality allows either trap to compensate for the other during replacement, improving odor prevention without requiring fundamentally different components or complex control systems
Solution Approach 2:
The second odor trap is positioned specifically at the drain line connection point to provide localized odor blocking capability exactly where needed during the replacement process, concentrating the additional complexity only where it provides maximum benefit
