Solution Overview
Problem
Current radiator-valve and lockshield valve connection methods are inefficient, requiring multiple elements and temporary sealing solutions, leading to leaks, increased maintenance, and environmental concerns due to nickel-plated brass usage.
Innovation Solution
A connection device featuring a reducing plug with internal hydraulic reduction and a sliding nut for single-element hydraulic reduction, eliminating the need for external sealing agents and reducing the number of sealing points, while using recycled sheet metal for improved safety and compatibility with various radiator types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple elements (reducing plug, nut-sleeve assembly, sealing joints) are used for connection, then adaptability to different radiator and valve sizes is improved, but device complexity increases and reliability decreases due to multiple sealing points
Solution Approach 1:
The patent merges the reducing plug and nut-sleeve assembly into a single integrated connection element. This unified component combines the hydraulic reduction function with the connection function, eliminating the need for separate elements and reducing the number of sealing points from multiple joints to a single sealing interface, thereby simplifying the device while maintaining adaptability.
Solution Approach 2:
The connection element is designed with universal applicability to work with different radiator and valve sizes through its reducing plug geometry. The single element performs multiple functions: hydraulic reduction, mechanical connection, and sealing, making it compatible with various standards (DN15, DN20, DN25) without requiring different component sets.
2Reliability
If multiple sealing joints are used, then sealing reliability is improved, but maintenance frequency increases and loss of time occurs due to more potential leak points
Solution Approach 1:
The patent extracts and eliminates the unnecessary sealing joints from the connection assembly. By removing the intermediate sealing interfaces between separate elements, the design reduces the number of potential leak points while maintaining adequate sealing through the optimized single sealing joint in the integrated connection element.
3Manufacturing precision
If nickel-plated brass is used for the nut-sleeve assembly, then manufacturing precision and durability are improved, but environmental harm increases due to nickel contamination
Solution Approach 1:
The patent changes the material parameter of the connection element from nickel-plated brass to stainless steel. This material substitution eliminates nickel contamination while maintaining or improving manufacturing precision and durability through the inherent properties of stainless steel, which offers comparable or superior mechanical properties and corrosion resistance.
4Reliability
If external sealing agents (teflon, hemp, sealing thread) are used, then sealing effectiveness is improved, but loss of substance occurs and environmental impact increases
Solution Approach 1:
The patent implements self-service sealing through the integrated connection element's inherent sealing design. The sealing joint is built into the structure of the connection element itself, eliminating the need for external sealing agents. The sealing functionality is intrinsic to the component design, providing permanent sealing without requiring additional consumable materials.
