Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If purely mechanical lock solutions are used, then simplicity and reliability are achieved, but they cannot meet the requirements of electronic locking systems
Solution Approach 1:
The patent replaces complex electromechanical locking mechanisms with a simplified system that uses a locking pin with recess and a locking bolt that can be actuated by electromagnetic actuators (solenoids or motors). The core locking function remains mechanical, while electronic control is achieved through simple binary states (locked/unlocked) of the locking bolt position.
Solution Approach 2:
The locking device is divided into independent functional modules: a locking part with locking pin, a lock body with locking bolt, and separate electromagnetic actuators. This modular design allows each component to be optimized independently and facilitates electronic integration without increasing overall system complexity.
2Adaptability or versatility
If electromechanical components are added to achieve electronic locking, then electronic locking capability is achieved, but component complexity and susceptibility to errors increase
Solution Approach 1:
The patent minimizes electromechanical complexity by using simple electromagnetic actuators (solenoids or small motors) that only need to move the locking bolt between two positions, rather than controlling multiple complex mechanical components. The primary locking function remains mechanical, which is inherently more reliable.
Solution Approach 2:
The locking pin and locking bolt are designed to self-align and self-lock through their geometric features (recess and protrusion). The spring element automatically returns the locking bolt to the locked position after actuation, eliminating the need for complex control systems and reducing error susceptibility.
3Adaptability or versatility
If multiple electromechanical components are used, then electronic locking function is achieved, but manufacturing cost and maintenance requirements increase
Solution Approach 1:
The locking device is divided into independent functional modules: a locking part with locking pin, a lock body with locking bolt, and separate electromagnetic actuators. This modular design allows each component to be manufactured using standard processes and assembled independently, reducing overall manufacturing cost.
Solution Approach 2:
The patent uses simple, inexpensive components such as standard electromagnetic actuators (solenoids), spring elements, and basic mechanical parts that can be easily manufactured and replaced if needed, rather than using complex custom-designed electromechanical assemblies.
4Adaptability or versatility
If complex electromechanical locking devices are used, then electronic locking capability is achieved, but production complexity and maintenance needs increase
Solution Approach 1:
The locking device is divided into independent functional modules that can be manufactured separately using standard processes and assembled quickly. The locking pin, locking bolt, and electromagnetic actuators are separate components that do not require complex integration, improving production efficiency.
Solution Approach 2:
The locking bolt and electromagnetic actuators are designed as universal components that can be used in various locking device configurations. The standardized design allows for mass production and reduces tooling costs, improving overall production efficiency.
