Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toilet pipe sealing technologies face challenges in achieving quick and efficient sealing, especially in small spaces, leading to difficulties in assembly and disassembly, and are not effective in preventing air leakage, which can cause functional failures in siphon toilets.
Innovation Solution
A quick-seal connecting component comprising a first sealing ring, an expansion pipe, and a pipe type joint with radial protrusions and threads, allowing for interference fitting and radial expansion to create multiple sealing engagements, enabling efficient sealing and easy assembly/disassembly in tight spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a nut and sealing pad are used for locking the sealing connection, then the sealing effect is improved, but the assembly space requirement increases and disassembly becomes difficult
Solution Approach 1:
The sealing connection is divided into modular components: a sealing ring for creating the seal, an expansion pipe for providing radial expansion force, and a pipe type joint for structural support. This segmentation allows each component to perform its specific function efficiently without requiring additional locking mechanisms like nuts, enabling easy assembly and disassembly while maintaining reliable sealing.
2Reliability
If a traditional locking mechanism is used in small space, then the sealing connection is secure, but the space requirement exceeds available space
Solution Approach 1:
The sealing ring is nested within the expansion pipe, which in turn is inserted into the pipe type joint. This nested configuration allows the sealing mechanism to be compact and fit within limited space while still providing secure connection through the radial expansion force of the expansion pipe against the pipe type joint.
3Strength
If direct hard connection is used between ceramic support and component, then the connection strength is improved, but the sealing capability deteriorates
Solution Approach 1:
The pipe type joint features localized threading at specific positions to provide mechanical strength and secure connection to the ceramic support, while other portions maintain smooth surfaces to enable the expansion pipe and sealing ring to create effective sealing connections. This local differentiation of structural properties allows both strong connection and reliable sealing in different areas.
