Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex mechanical locking systems are used in firearms, then the breech can be securely locked, but the device complexity increases and manufacturing cost increases
Solution Approach 1:
The patent replaces the traditional mechanical locking system with an electromagnet-based system. The electromagnet uses magnetic fields to lock and unlock the breech body, eliminating the need for complex mechanical linkages, springs, and levers. This substitution maintains secure locking while significantly reducing mechanical complexity and manufacturing cost.
Solution Approach 2:
The patent extracts and removes unnecessary mechanical components from the traditional locking system. By using only the essential elements (electromagnet, breech body, and cartridge chamber), the design eliminates redundant mechanical parts, simplifying the overall construction while preserving the core locking function.
2Ease of operation
If traditional mechanical firing mechanisms are used, then the firing pin can be actuated, but the device complexity increases and cost increases
Solution Approach 1:
The patent replaces the traditional mechanical firing mechanism with an electromagnet-driven system. The electromagnet directly actuates the firing pin through magnetic force, eliminating the need for complex mechanical trigger linkages, sears, and springs. This simplifies the overall mechanism while maintaining ease of operation.
3Ease of manufacture
If simple breech design is used, then manufacturing cost decreases, but the reliability of locking may be compromised
Solution Approach 1:
The patent uses an electromagnet to provide reliable locking without requiring complex mechanical structures. The electromagnetic force can be precisely controlled to ensure secure locking, while the simpler physical structure reduces manufacturing cost and assembly complexity.

Function Achieved in This Case
The solution provides a cost-effective and reliable mechanism for locking and releasing the breech, ensuring efficient operation and reducing the likelihood of malfunctions, while allowing for simple design and effective actuation of the firing pin.
Implementation Method 1
the electromagnet is designed to move the breech body lock by generating a magnetic field and a resulting force acting on the breech body lock
Implementation Method 2
The breech locking device comprises an electromagnet for moving the breech body lock from the breech body release position to the breech body locking position
Implementation Method 3
the firing device may have a firing pin that is moved by means of the electromagnet
Implementation Method 4
the firearm with the firing device described above does not have to be a locked weapon, but may also be any other firearm
