Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing UV lamp modules in UV reactors are difficult to remove without causing water leakage due to stuck O-rings, posing safety risks and requiring operation shutdown for maintenance.
Innovation Solution
A UV lamp socket assembly with a dual-structured O-ring, a pivoting latch, and a compression spring that allows easy detachment and reattachment of the UV lamp without disrupting the reactor's operation, ensuring airtightness and preventing water leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single O-ring is used to seal the UV lamp module, then the structure is simple, but the O-ring gets stuck on the inner wall after long-term use making removal difficult
Solution Approach 1:
The single O-ring sealing structure is divided into two separate O-rings: a first O-ring for sealing the gap between the UV lamp module and through hole, and a second O-ring for sealing the gap between the UV lamp module and lamp socket. This segmentation prevents the O-rings from sticking to each other and to the inner wall, enabling easy removal while maintaining sealing effectiveness.
2Ease of operation
If the UV lamp module is forcibly drawn out when O-ring is stuck, then the UV lamp can be removed, but the O-ring may be damaged causing water leakage and safety risks
Solution Approach 1:
The patent introduces a backup ring positioned behind the second O-ring to provide mechanical support and prevent the O-ring from being damaged during removal operations. This cushioning element ensures that even if the O-ring becomes stuck, it can be removed without damage to the sealing component, maintaining reliability.
3Ease of repair
If the UV lamp module is removed to replace the UV lamp, then the lamp can be replaced, but the reactor operation must be stopped
Solution Approach 1:
The UV lamp module is segmented into separable components: the lamp socket assembly (containing the O-rings and sealing structures) and the UV lamp itself. This allows the UV lamp to be replaced by detaching only the lamp from the socket assembly, without requiring removal of the entire module from the reactor, thus maintaining continuous operation.
Solution Approach 2:
The lamp socket assembly acts as an intermediary component between the reactor and the UV lamp. It provides a detachable connection that allows the UV lamp to be replaced independently while the socket assembly remains in place, enabling maintenance without stopping reactor operation.
4Reliability
If the O-ring is worn out due to long-term use, then the sealing effectiveness decreases, but the UV lamp module cannot be removed for replacement
Solution Approach 1:
The sealing system is segmented into multiple independent O-rings positioned at different locations. This allows individual O-rings to be inspected and replaced without affecting the entire sealing system or requiring removal of the UV lamp module. Worn O-rings can be accessed and replaced through the detachable lamp socket assembly.
Solution Approach 2:
The detachable lamp socket assembly design enables operators to service and replace worn O-rings independently without requiring specialized tools or reactor shutdown. The modular design allows easy access to sealing components for maintenance.
