Solution Overview
Problem
Fluid treatment systems face issues with fluid leakage due to temperature fluctuations causing loosening of connections between radiation source assemblies and the system, leading to potential leaks, especially when using conventional O-ring seals and plastic components.
Innovation Solution
A sleeve holder assembly with a sleeve bolt assembly, sleeve holder receptacle, and radiation transparent sleeve, featuring asymmetric locking features, locking ratchet tabs, and cushioning elements to maintain a consistent compressive force and prevent loosening, even with temperature changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional O-ring seals and plastic components are used in radiation source assemblies, then ease of manufacture is improved, but reliability deteriorates due to temperature fluctuations causing loosening of connections and fluid leakage
Solution Approach 1:
The connection assembly incorporates a spring mechanism that dynamically adjusts the compressive force applied to the O-ring seal. The spring maintains constant pressure on the sealing surface despite temperature-induced expansion and contraction of plastic components, ensuring continuous reliable sealing while allowing for thermal movement without connection loosening
Solution Approach 2:
The invention changes the physical state and properties of the connection system by introducing a compliant spring element that compensates for dimensional changes in plastic components due to temperature fluctuations. This parameter adjustment maintains optimal sealing pressure across varying thermal conditions, resolving the reliability issue while retaining plastic manufacturing advantages
2Ease of manufacture
If plastic components are used in sleeve holder assemblies, then ease of manufacture and cost are improved, but stability deteriorates due to loosening of connections under temperature fluctuations
Solution Approach 1:
The spring-loaded connection assembly provides dynamic compensation for thermal expansion and contraction of plastic components. As temperature fluctuates causing plastic to expand or contract, the spring automatically adjusts its compression to maintain constant sealing pressure and connection integrity, preventing loosening while allowing the plastic components to move freely with temperature changes
Solution Approach 2:
The invention converts the harmful effect of plastic component dimensional instability under temperature fluctuations into a beneficial self-adjusting mechanism. The spring uses the movement caused by thermal expansion/contraction to maintain optimal sealing pressure, transforming the instability issue into a feature that automatically compensates for dimensional changes
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 sleeve holder assembly effectively reduces the likelihood of fluid leakage by maintaining a secure connection despite temperature fluctuations, allowing for easy installation and removal for servicing while ensuring reliable sealing.
Implementation Method 1
a spring element which engages with the bracket assembly and applies a consistent compressive force to a sealing surface
Implementation Method 2
The primary reason for this is it is conventional to use O-ring seals or the like to prevent leakage of fluid from the fluid treatment system
