Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speed regulators for internal combustion engines (ICEs) and turbines lack a protection system to prevent over-acceleration, which can lead to damage and safety risks due to uncontrollable power supply.
Innovation Solution
An over-acceleration protection device is integrated with the speed regulator, utilizing centrifugal force and a hydraulic trigger circuit to cut off power supply when excessive rotation is detected, featuring adjustable activation speed settings to accommodate various engine models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a speed regulator is used to control fuel and steam supply to ICEs and turbines, then the revolutions can be controlled, but there is no protection system against over-acceleration
Solution Approach 1:
The patent merges the protection function with the existing speed regulator by integrating a protection piston and counterweights into the regulator's housing. The protection device shares the same housing, oil supply, and control mechanism as the speed regulator, eliminating the need for a separate protection system while adding over-acceleration protection capability.
Solution Approach 2:
The speed regulator housing is designed to serve dual functions: controlling normal operation (fuel/steam supply) and providing over-acceleration protection. The protection piston and counterweights are integrated into the existing regulator structure, allowing one device to perform both regulation and protection functions.
2Speed
If the speed regulator controls power supply to ICEs and turbines, then revolutions are regulated, but immediate shutdown capability is lacking during over-acceleration
Solution Approach 1:
The patent uses a hydraulic mechanism with pressurized oil to achieve immediate shutdown. When over-acceleration occurs, the protection piston moves under hydraulic pressure to directly actuate the fuel valve or steam valve, providing rapid closure that mechanical linkages alone could not achieve. The hydraulic system enables fast response time for emergency shutdown.
Solution Approach 2:
The protection device is pre-positioned with the protection piston, counterweights, and hydraulic connections ready for immediate action. The counterweights are continuously positioned by centrifugal force, and the protection piston is pre-loaded with spring pressure, so that when over-acceleration occurs, the shutdown action can be executed immediately without delay for mechanical assembly or manual intervention.
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 device ensures immediate shutdown of the engine or turbine during over-acceleration, preventing damage and ensuring user safety by effectively cutting off power supply, thus protecting both the machinery and surrounding individuals.
Implementation Method 1
The present invention is based on the phenomenon of centrifugal force. It has internally a system of counterweights which rotate during its operation, tending to move to the periphery of the imaginary circle of rotation

AI summary
Over-acceleration protection mechanism for ICE or turbine speed regulator with a bushing driven by the gears. The bushing, the component, the washer, the thread, are joined together. The component screws to the thread through the thread. The weights are fitted to the component through the pins and the safety clips, including the valve which is secured by the nut. The lid is screwed to the bushing by means of the screws, while the counterweights come out of the openings of the lid. The thrust bearing and the pressure spring are mounted on the component, adjusted by the screw. The device operates through the centrifugal force which forces the counterweights to rotate in its direction of rotation and to displace the valve by compressing the spring. Then the holes of the fittings communicate with each other, allowing the oil to pass through the joints and the tube and actuate the system.
