Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a glass bubble spraying head is used for automatic fire fighting, then the device can automatically spray water when temperature increases, but it cannot automatically cut off water after the fire is extinguished, causing water waste and flooding
Solution Approach 1:
The patent replaces the disposable glass bubble mechanism with a reusable valve system controlled by magnetic fields. The magnetic loop assembly and magnetic core assembly interact through magnetic force to automatically open and close the valve, eliminating the need for electrical power and providing both automatic activation and automatic shut-off functionality.
Solution Approach 2:
The patent uses temperature-sensitive parameters to control valve operation. When temperature increases, the organic solvent evaporates and expands, pushing the piston to open the valve. When temperature decreases, the solvent contracts, allowing the bias spring to close the valve,从而实现 automatic shut-off and preventing water waste.
2Extent of automation
If an intelligent automatic fire fighting device is used, then the valve can automatically switch on and off, but it requires electricity to operate which is unavailable or damaged in fire accidents
Solution Approach 1:
The patent replaces electrical control systems with a purely mechanical-magnetic control system. The magnetic loop assembly generates magnetic fields that interact with the magnetic core assembly through magnetic attraction and repulsion forces, eliminating the need for electrical power while maintaining automatic valve control functionality.
Solution Approach 2:
The valve system is self-activating through temperature-sensitive organic solvent that automatically expands to open the valve and contracts to close it. The magnetic field interactions are self-regulating based on temperature changes, requiring no external power source or control system.
3Extent of automation
If a conventional automatic sprinkler valve is used, then the valve can be automatically controlled by temperature, but it is difficult to manually open and close for overhaul or special situations
Solution Approach 1:
The patent designs the valve to perform multiple functions: automatic temperature-based control through the organic solvent and piston mechanism, magnetic field-based automatic control through the magnetic loop and core assemblies, and manual control through the manual adjusting rod that directly moves the piston. This multi-functionality ensures the valve can operate automatically under normal conditions while remaining manually operable for maintenance and special situations.
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
Enables automatic temperature-dependent valve operation and manual override, improving efficiency and convenience by preventing water wastage and ensuring reliable fire fighting system functionality.
Implementation Method 1
The magnetic core assembly is inserted into the piston barrel and able to move upwardly and downwardly under effects of magnetic force lines of the magnetic loop assembly within the magnetic loop sheath
Implementation Method 2
The memory alloy is sleeved into an outer part of the manual movable rod
Implementation Method 3
The heat concentrating cover is connected via rotating to the threads on the manual adjusting rod
Implementation Method 4
When the indoor environment temperature rapidly increases, the organic solvent within the glass bubble spraying head evaporates to break the glass bubble

AI summary
A double-switched automatic sprinkler valve in a field of automatic controlling devices for cooling and fire fighting is disclosed. A memory alloy, sleeved outside a manual adjusting rod at an upper part of a valve lid, opens and closes a valve according to temperature changes. The valve can also be opened and closed by rotating the manual adjusting rod. A piston is provided within a valve body. A bias spring, provided at an internally upper part of a valve cover, has an upper part resisting against an internally upper part of the valve cover. A movable rod, a magnetic loop assembly and a magnetic loop sheath together are sleeved outside a piston barrel. The manual adjusting rod is rotated into a middle hole of the movable rod. A heat concentrating cover is connected to the manual adjusting rod via rotating.
