Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable-connected power supply is used for sensor, then continuous power supply is ensured, but exposed cable arrangement becomes unattractive
Solution Approach 1:
The patent extracts the power supply dependency from the sensor system by using a purely mechanical sensing mechanism. The magnetic field sensing element operates without requiring electrical power connection, eliminating the need for cable arrangements while maintaining continuous operational capability.
Solution Approach 2:
The patent replaces the electrical power-dependent sensing system with a mechanical/magnetic field-based sensing mechanism. The magnetic field interacts with the sensing element to produce mechanical displacement that directly actuates the alarm mechanism, substituting electrical systems with mechanical ones.
2Ease of operation
If battery-powered supply is used for sensor, then installation flexibility is improved, but sensor failure occurs when battery is exhausted
Solution Approach 1:
The sensor system is designed to be self-powered through the mechanical energy of the moving door or window itself. The motion of the door/window generates the mechanical energy needed to actuate the alarm, eliminating the need for external battery power while ensuring continuous reliability.
Solution Approach 2:
The patent replaces battery-powered electrical systems with a mechanical energy conversion system. The kinetic energy from door/window motion is converted into mechanical displacement of the alarm actuator, providing both installation flexibility and continuous operational reliability without battery dependency.
3Productivity
If conventional power-dependent sensor is used, then sensing function is achieved, but security protection is lost when power is unavailable
Solution Approach 1:
The patent replaces power-dependent electronic sensing with a mechanical field-based sensing system. The magnetic field generated by the moving door or window directly actuates the alarm mechanism through mechanical displacement, ensuring the sensing and alarm function operates reliably without any electrical power source.
4Reliability
If non-electrical power operated sensor is used, then reliability without power is improved, but device complexity increases due to gas valve and sound devices
Solution Approach 1:
The gas valve mechanism serves multiple functions: it acts as the sensing element that detects door/window position, the actuator that generates alarm sound through gas release, and the power source itself. This multi-functionality reduces overall system complexity despite the presence of additional components.
Solution Approach 2:
The patent merges the sensing function, actuation function, and alarm function into a single integrated mechanical system. The magnetic field sensing, mechanical displacement, gas release, and sound generation are combined into one cohesive mechanism, reducing the need for separate electrical components and simplifying the overall system architecture.
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 sensor system effectively monitors door or window positions without power, providing reliable alerts to users through distinct sound frequencies, enhancing security without the drawbacks of traditional power-dependent sensors.
Implementation Method 1
When the first plug body moves, the first gas chamber generates a first ultrasonic sound. When the second plug body moves, the second gas chamber generates a second ultrasonic sound.

AI summary
A non-electrical power operated sensor determining the position and movement of a first object in relation to a second object includes a valve on the first object. The valve has a housing and a cavity. A first sound device is mounted on one side of the housing and connected to the cavity. A second sound device is mounted on the other side of the housing and connected to the cavity. A piston connects the second object and the valve. The piston includes a push rod extending from one side of the plug body and the push rod being moved one way or another way causes one sound or another sound to be made. The disclosure also provides a monitoring system listening for the one sound or for the other sound, the system being able to instantly communicate with an electronic device of a user.
