Trigger Mechanism Selectable Pull Characteristics Mode Selector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms typically have fixed trigger mechanisms, limiting the ability to adjust trigger pull characteristics, which can impact accuracy and shooting style, as most firearms come with only a single trigger mechanism that must be selected and installed before use.
Innovation Solution
A trigger mechanism with a mode selector element that allows selection between different disconnector elements, providing various pull characteristics, such as two-stage and single-stage triggers, enabling shooters to choose between distinct trigger modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed trigger mechanism is installed in the firearm, then the device complexity is reduced and ease of manufacture is improved, but the adaptability is worsened because the shooter cannot adjust trigger pull characteristics for different shooting situations
Solution Approach 1:
The trigger mechanism is designed to perform multiple functions by incorporating a mode selector element that allows switching between different trigger modes (single-stage and two-stage). This enables a single trigger mechanism to provide various pull characteristics (different takeup, break, and overtravel values) that would otherwise require multiple separate trigger mechanisms, thereby improving adaptability without proportionally increasing device complexity.
Solution Approach 2:
The trigger mechanism incorporates a mode selector element that can be adjusted to different positions to dynamically change the trigger pull characteristics. The disconnector element's position relative to the trigger arm can be modified to alter the takeup distance and force requirements, allowing the system to adapt its behavior based on shooting needs while maintaining a relatively simple overall structure.
2Adaptability or versatility
If multiple trigger mechanisms with different pull characteristics are provided, then the adaptability is improved, but the device complexity and ease of operation are worsened due to the need to replace trigger mechanisms
Solution Approach 1:
Instead of requiring separate trigger mechanisms for different shooting styles, the invention integrates multiple trigger modes within a single mechanism. The mode selector element allows shooters to switch between single-stage and two-stage trigger characteristics without any physical replacement or complex installation procedures, greatly improving ease of operation while maintaining full adaptability.
Solution Approach 2:
The mode selector element provides dynamic switching capability that allows the shooter to change trigger characteristics on-the-fly during use. This eliminates the static nature of fixed trigger mechanisms and the cumbersome process of replacing triggers, enabling quick adaptation to different shooting situations with simple rotational or positional adjustments.
3Measurement precision
If a two-stage trigger is used to improve accuracy by minimizing movement at the break, then the measurement precision is improved, but the productivity is worsened due to the longer trigger pull time required
Solution Approach 1:
The mode selector element enables dynamic switching between two-stage and single-stage trigger modes. When rapid fire is needed, the shooter can select single-stage mode for faster trigger response. When precision is prioritized, two-stage mode provides the controlled break characteristic. This dynamic adaptability allows optimization of the accuracy-speed trade-off based on immediate shooting requirements rather than being fixed in one configuration.
Solution Approach 2:
The invention allows changing the trigger pull parameters (takeup distance, break force, overtravel) by selecting different modes. In two-stage mode, the parameters are configured for precision with longer takeup and distinct break. In single-stage mode, the parameters are adjusted for speed with shorter overall travel and direct break. This parameter variability enables the shooter to optimize for either accuracy or productivity depending on the situation.
