Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single action trigger mechanism with a release lever is used, then the firearm is easy to operate, but it is prone to accidental firing
Solution Approach 1:
The antagonist lever is pre-loaded with inertial forces that automatically contrast and prevent the release lever from accidentally releasing the striker. This preliminary counter-action is built into the lever's mass distribution, creating an inherent safety mechanism that opposes accidental firing before it can occur.
Solution Approach 2:
The antagonist lever acts as a counterweight system where its distributed mass creates inertial forces that balance and oppose the release lever. This counterbalancing mechanism ensures that the release lever cannot accidentally trigger the striker, as the antagonist lever's inertial resistance prevents unintended release.
2Length of moving object
If the total length and height of the firearm are reduced for compactness, then the firearm is easier to stow, but the mechanisms for safety and operation become more constrained
Solution Approach 1:
The firearm employs dynamic mechanisms where the closing block and antagonist lever move and adjust during operation. The closing block tilts and engages at different stages, and the antagonist lever's inertial forces dynamically contrast the release lever, allowing compact dimensions while maintaining full operational capability through motion-based functionality.
Solution Approach 2:
The closing block is designed to move along a direction tilted with respect to the barrel axis, utilizing a different dimensional approach to achieve breech closure. This tilted motion path allows the mechanism to function effectively within reduced length and height constraints by exploiting angular movement rather than purely linear displacement.
