Spring-Loaded Deodorant Sewer Pipe Cover Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deodorant sewer pipes in existing systems fail to maintain deodorization when not in use for extended periods due to water evaporation, leading to potential blockages from foreign matter.
Innovation Solution
A deodorant sewer pipe design featuring a spring-loaded cover within the pipe that opens during water flow for drainage and resets to block odors when water is absent, utilizing a silica gel or plastic disc-shaped blocking portion and O-rings for sealing, ensuring continuous deodorization and preventing blockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water sealing is used for deodorization in sewer pipes, then deodorization is achieved during use, but the water dries up after long periods of non-use causing loss of deodorization and foreign matter blockage
Solution Approach 1:
The patent employs a dynamic cover mechanism that automatically moves between open and closed positions based on water flow conditions. The cover is connected via a hinge and controlled by a float that rises and falls with water level changes, allowing the system to adapt its sealing state dynamically rather than remaining static, thus maintaining deodorization effectiveness whether the pipe is in use or not.
Solution Approach 2:
The system utilizes the water flow itself to activate the deodorization mechanism. When water flows, the float rises and opens the cover automatically; when water stops, the float falls and closes the cover automatically. This self-activating mechanism requires no external power or manual intervention, ensuring the cover closes and maintains sealing precisely when needed (during non-use periods).
2Reliability
If the sewer pipe remains closed for deodorization, then odor upsurge is prevented, but drainage function is compromised when water flow is needed
Solution Approach 1:
The cover is designed as a hinged, movable component rather than a fixed closure. It rotates open when the float rises with water flow, allowing drainage, and rotates closed when the float falls during non-use, maintaining odor sealing. This dynamic motion reconciles the conflicting requirements of sealing and drainage by timing the open/closed states with actual operational needs.
Solution Approach 2:
The float mechanism provides continuous feedback about water flow conditions to the cover position. When water flows in, the float rises and signals the cover to open; when water stops, the float falls and signals the cover to close. This feedback loop ensures the cover responds automatically and accurately to drainage requirements, maintaining both sealing effectiveness and drainage functionality.
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 enables automatic blocking and deodorization, preventing odor upsurge and foreign object blockages by using a spring mechanism to reset the cover and maintain pipe sealing, even when the pipe is not in use, thus addressing the issue of water evaporation and maintaining effective deodorization.
Implementation Method 1
the cover is reset through an elastic force of the spring so as to block the sewer pipe body and achieve deodorization
Implementation Method 2
when there is a water flow, the spring and the cover move downward to achieve drainage
