Active Bolt Release Arrangement Rotational Sleeve Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing active bolt release arrangements are not space-efficient due to the need for linear movement of components, which can complicate their integration and increase the installation height, and they lack a robust and rapid release mechanism.
Innovation Solution
An active bolt release arrangement featuring a nut with radial movement and a sleeve part that, upon actuation, rotates a predetermined distance to create a release space, allowing radial movement of the nut portions and enabling a compact, rapid, and robust bolt release without linear movement of the sleeve part, utilizing a pyrotechnical actuator to turn the sleeve part and a frangible nut design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If linear movement of the sleeve part is used to release the bolt, then the release mechanism is simple to understand, but the installation height increases and space efficiency decreases
Solution Approach 1:
The patent transitions from linear movement (one dimension) to rotational movement (angular dimension) of the sleeve part. The sleeve part rotates around the bolt axis to form the release space, eliminating the need for axial displacement and reducing installation height requirements while maintaining the release function.
2Ease of manufacture
If linear movement of the sleeve part is used to release the bolt, then the mechanism is easy to implement, but the device becomes less space-efficient and more complex to integrate
Solution Approach 1:
The release mechanism uses rotational movement in the angular dimension instead of linear movement in the axial dimension. This dimensional change simplifies integration into compact spaces while maintaining manufacturing feasibility through standard rotational joint designs.
3Productivity
If a robust and rapid release mechanism is implemented, then the bolt release is quick and reliable, but the device complexity increases
Solution Approach 1:
The patent changes the movement parameter from linear displacement to rotational angle. The sleeve part rotates a specific angular distance to quickly form the release space, enabling rapid bolt release while using a simple rotational mechanism rather than a complex linear actuation system.

Function Achieved in This Case
This solution provides a space-efficient and rapid bolt release mechanism, ensuring a compact installation height and robust operation by eliminating the need for linear sleeve part movement, while the pyrotechnical actuator ensures quick and reliable separation of the bolt from the nut.
Implementation Method 1
a pyrotechnical actuator adapted for, upon deployment, moving the sleeve part relative to the nut to a released position forming a release space allowing radial movement of the nut portions, wherein the pyrotechnical actuator is arranged for turning, upon deployment, the sleeve part a predetermined rotational distance to the released position

AI summary
An active bolt release arrangement includes a nut having nut portions adapted for radial movement, a sleeve part encircling the nut and having contact portions in contact with the nut portions in order to prevent the nut portions from radial movement, and a pyrotechnical actuator. The pyrotechnical actuator is adapted for, upon deployment, moving the sleeve part relative to the nut to a released position forming a release space allowing radial movement of the nut portions. The pyrotechnical actuator is arranged for turning, upon deployment, the sleeve part a predetermined rotational distance to the released position, such that radial movement of the nut portions by formation of the release space is allowed, thereby causing release of a bolt connected to the bolt release arrangement.
