Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motor or solenoid is used as a powered actuator in the lock device, then the locking and unlocking function is achieved, but the energy consumption increases and the design becomes more complex
Solution Approach 1:
The patent replaces traditional mechanical actuators (motors, solenoids) with a magnetic field-based system. A magnet movable between blocking and unblocking positions creates magnetic circuits that directly control the locking mechanism without requiring continuous electrical power or complex mechanical components, thereby reducing energy consumption while maintaining reliability
Solution Approach 2:
The patent extracts and eliminates the need for continuous power supply and complex actuator mechanisms by using a magnet that can be positioned between blocking and unblocking states. The magnetic circuit is established only when needed, removing the energy-consuming continuous operation of traditional actuators
2Reliability
If a motor or solenoid is used as a powered actuator, then the locking and unlocking function is achieved, but the device size and complexity increase
Solution Approach 1:
The patent replaces complex mechanical actuators with a simplified magnetic field-based system. The magnet's movement between blocking and unblocking positions directly controls the locking mechanism, eliminating the need for motors, solenoids, and associated mechanical components, thereby reducing device complexity
Solution Approach 2:
The magnet serves multiple functions: it acts as both the actuating element and the control element for the locking mechanism. By moving between blocking and unblocking positions, it performs both the actuation and the control functions that would otherwise require separate components
3Use of energy by moving object
If a magnet establishes a magnetic circuit through the coil section in both blocking and unblocking positions, then the blocking member can be held in each position without power supply, but the magnetic field control must be precise
Solution Approach 1:
The magnet serves itself by establishing the magnetic circuit through the coil section in both blocking and unblocking positions. The magnetic field naturally seeks the path of least reluctance, automatically positioning itself correctly without requiring external control mechanisms or precise active management, thereby reducing power supply requirements while maintaining control precision
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 solution achieves low energy consumption, simplified design, reduced size, and reliable operation with minimal power requirements, ensuring efficient locking and unlocking mechanisms.
Implementation Method 1
The magnet generates a magnetic field. The blocking member may be held stationary in each of the blocking position and the unblocking position only by means of this magnetic field
Implementation Method 2
the magnet establishes a magnetic circuit through the coil section and the blocking member blocks movement of the transfer element
Implementation Method 3
The coil is energized by connection to a source of electrical current and thereby generates magnetic flux which influences the shaft to move in one direction
