Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metal valve systems in combi boilers and similar devices suffer from corrosion, leading to uncontrolled fluid transfer and turbulent flow conditions, as they are not resistant to high temperatures, chemicals, and pressure.
Innovation Solution
A jointless and welding-free valve made from plastic material, comprising two main components with O-ring sealing elements, allowing for compact, high-temperature, chemical, and pressure-resistant fluid flow control without the need for welding or joints, assembled using nail components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal valve systems are used in combi boilers, then the valve can control fluid flow, but the valve suffers from corrosion over time leading to uncontrolled flow and turbulent conditions
Solution Approach 1:
The patent changes the material parameter from metal to plastic, transforming the valve's chemical and physical properties to resist corrosion while maintaining structural integrity under high temperature and pressure conditions
Solution Approach 2:
The patent employs composite plastic material construction with integrated sealing elements, combining multiple material properties (corrosion resistance, thermal stability, pressure resistance) into a unified valve structure that eliminates the harmful effects of corrosion
2Temperature
If metal valve systems are used, then the valve can regulate fluid transfer, but the valve is not resistant to high temperatures, chemicals, and pressure
Solution Approach 1:
The patent modifies the material parameters by selecting plastic materials with specific thermal and mechanical properties that can withstand high temperatures and pressures simultaneously, changing the fundamental material characteristics from metal to corrosion-resistant plastic
3Ease of manufacture
If traditional valve assembly methods are used, then the valve can be manufactured, but joints and welding create potential failure points and increase complexity
Solution Approach 1:
The patent merges multiple valve components into a single integrated plastic body, eliminating the need for separate joints and welding operations, thereby simplifying the overall structure and reducing potential failure points while maintaining manufacturing feasibility
