Firearm Assembly Shock Reduction via Return Delay Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms, including remote-controlled armed surveillance robots, experience recoil shock during firing, leading to accuracy degradation and mechanical damage due to the lack of effective shock reduction mechanisms.
Innovation Solution
A firearm assembly with a base, a firearm coupling unit that moves forward and backward, an elastic support unit, and a return delay unit, which includes a damper and a frictional force generator to control the speed of the firearm coupling unit's return to its original position, ensuring the bolt assembly returns to its original position before the firearm, thereby reducing forward and backward shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the firearm coupling unit returns quickly to its original position after firing, then the shooting speed and productivity are improved, but the recoil shock and mechanical damage increase
Solution Approach 1:
The patent applies beforehand cushioning by introducing a return delay unit with damping mechanism that actively controls and cushions the return motion of the firearm coupling unit. The damping force is specifically designed to counteract the recoil shock during the return phase, protecting the mounting structure while maintaining acceptable shooting speed.
Solution Approach 2:
The patent implements dynamics by making the damping force variable rather than constant. The return delay unit adjusts the damping force based on the movement state of the firearm coupling unit, providing stronger resistance when shock is highest and reducing resistance as the system approaches equilibrium, thereby optimizing both shock reduction and return speed.
2Strength
If the firearm coupling unit is rigidly fixed to the base, then the structural strength and stability are improved, but the recoil shock transmission and mechanical damage increase
Solution Approach 1:
The patent introduces an intermediary element - the return delay unit with damping mechanism - positioned between the firearm coupling unit and the base. This intermediary absorbs and dissipates shock energy during the return motion, preventing direct transmission of recoil forces to the rigid base structure while maintaining structural integrity.
3Reliability
If the bolt assembly returns before the firearm coupling unit, then the firearm operation reliability is improved, but the forward shock and accuracy degradation increase
Solution Approach 1:
The patent applies periodic action by establishing a specific temporal sequence in the return motion: the bolt assembly completes its return first, followed by the controlled return of the firearm coupling unit. This periodic, staged return pattern ensures reliable firearm operation while the damping mechanism controls the timing and magnitude of shock generation.

Function Achieved in This Case
The solution effectively reduces the forward and backward shocks during firing, enhancing the accuracy of shooting and preventing mechanical damage by ensuring the bolt assembly and firearm coupling unit return to their original positions in a controlled manner, thus minimizing the transmission of shock forces to the firearm support apparatus.
