Bladed Firearm Bolt Stop Lever Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Semiautomatic firearms pose regulatory challenges as users are unsure about the legality of their firearms due to varying state laws, leading to difficulties in compliance, particularly when firearms have more than the allowed number of regulated features.
Innovation Solution
A device is developed to convert semiautomatic firearms into non-semiautomatic firearms by using a bolt stop lever and a spring mechanism that restricts the bolt's motion, requiring user intervention to chamber each round, thereby altering the firearm's function without additional modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a semiautomatic firearm is converted to non-semiautomatic by adding a bolt stop lever mechanism, then compliance with firearm regulations is achieved, but device complexity increases
Solution Approach 1:
The conversion device is divided into separate functional components: a bolt stop lever, a spring mechanism, and a bolt release mechanism. Each component performs a specific function, allowing the system to be installed on existing semiautomatic firearms without replacing the entire weapon system. This segmentation enables regulatory compliance while maintaining the original firearm's core functionality.
Solution Approach 2:
The bolt stop lever acts as an intermediary component between the bolt and the receiver. It intercepts the bolt's automatic cycling motion and requires manual intervention through the bolt release mechanism. This intermediary element transforms the semiautomatic operation into non-semiautomatic operation without fundamentally altering the original firearm design.
2Adaptability or versatility
If existing semiautomatic firearms are altered to comply with regulations, then legal compliance is achieved, but manufacturing cost increases
Solution Approach 1:
The conversion device utilizes spring-loaded mechanisms that provide dynamic operation. The spring automatically returns the bolt stop lever to its blocking position after the bolt is released, eliminating the need for complex mechanical linkages or powered systems. This dynamic approach reduces manufacturing complexity and cost while achieving the desired non-semiautomatic function.
Solution Approach 2:
The spring mechanism automatically resets the bolt stop lever after each manual bolt release, without requiring additional user intervention or external power sources. The system self-regulates its operation, blocking the bolt after firing and requiring manual release only when needed, thereby simplifying the overall mechanism and reducing manufacturing requirements.
3Adaptability or versatility
If a bolt stop lever is used to restrict bolt motion, then semiautomatic function is eliminated, but ease of operation is reduced
Solution Approach 1:
The bolt release mechanism serves multiple functions: it releases the bolt from the blocked position, allows the firearm to return to semiautomatic operation temporarily, and provides user control over the firing cycle. This multi-functionality maintains ease of operation by giving the user flexible control options while still achieving regulatory compliance when in non-semiautomatic mode.

Function Achieved in This Case
This solution simplifies and reduces the cost of compliance with firearm regulations, allowing owners to easily convert their firearms between states with different regulations by altering the firearm's function without requiring additional modifications, ensuring compliance regardless of existing features.
Implementation Method 1
a spring configured to be installed in contact with the bolt stop lever and the semiautomatic firearm receiver such that the spring exerts a force on the bolt stop lever to retain the bolt stop lever in a first position

AI summary
A device for converting a semiautomatic firearm to a non-semiautomatic firearm. The device includes a bolt stop lever pivotally attachable to a receiver of a firearm, a spring configured to be installed in contact with the bolt stop lever and a firearm receiver such that the spring exerts a force on the bolt stop lever to retain the bolt stop lever in a first position, and, a bolt release mechanism operatively coupleable to the bolt stop lever and configured to pivot the bolt stop lever against the force of the spring into a second position. The bolt release mechanism is operatively decoupled from the bolt stop lever when the bolt stop lever reaches the second position. When in the first position the bolt stop lever restricts motion of a bolt of the firearm, and when in the second position, the bolt stop lever permits motion of the firearm bolt.
