Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compact disrupter barrels used for disabling IEDs cannot absorb the recoil from high-energy cartridges, leading to unsafe travel and potential damage to surrounding objects and equipment, and are not suitable for mounting on lightweight robots due to recoil-induced damage.
Innovation Solution
An ejection and recovery system incorporating a parachute and lanyard mechanism to restrain and recover the disrupter barrel, limiting its travel and preventing damage, which includes a housing with a channel for the barrel, a tube for the parachute, and a lanyard connected to both the parachute and the barrel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high energy cartridges are used to destroy IEDs, then the disrupter can effectively disable IEDs, but the recoil causes the disrupter to travel at high velocity for long distance
Solution Approach 1:
A recovery system is introduced as an intermediary mechanism between the disrupter barrel and the ground. This system includes a housing mounted on the disrupter barrel, a recovery line extending from the housing, and a recovery device (such as a parachute or impact attenuator) at the end of the line. The recovery system acts as a mediator that absorbs the recoil energy and prevents the barrel from traveling long distances, thus resolving the contradiction between using high energy cartridges and controlling recoil travel.
Solution Approach 2:
The recovery device (parachute or impact attenuator) is deployed beforehand to cushion the recoil impact. The parachute opens before the barrel completes its recoil travel, creating air resistance that slows the barrel down. This prior cushioning prevents the harmful effect of long-distance recoil travel while allowing the use of high energy cartridges for effective IED destruction.
2Ease of operation
If the disrupter is not restrained, then it can be操作简单, but it causes damage to surrounding objects and equipment
Solution Approach 1:
The recovery system serves as an intermediary protective layer between the disrupter barrel and surrounding objects. The housing, recovery line, and recovery device work together to intercept and dissipate the recoil energy before it can damage surrounding objects. This allows the disrupter to remain操作简单 (easy to operate) while preventing harmful effects on the environment.
Solution Approach 2:
The harmful recoil energy is converted into a beneficial effect by the recovery system. The kinetic energy from recoil is transformed into potential energy in the deployed parachute or absorbed by the impact attenuator, then dissipated as heat and sound. This converts the harmful recoil into a controlled energy dissipation process that protects surrounding objects while maintaining ease of operation.
3Weight of moving object
If the disrupter barrel is mounted on lightweight robots, then mobility is improved, but the recoil causes significant damage to the robot
Solution Approach 1:
The recovery system acts as a protective intermediary between the lightweight robot and the high-energy disrupter barrel. The housing mounted on the barrel, combined with the recovery line and device, creates a buffer that prevents direct transmission of recoil forces to the robot. This allows the robot to remain lightweight while protecting it from recoil-induced damage.
Solution Approach 2:
The recovery device is deployed beforehand to cushion the recoil forces before they can reach the robot. The parachute creates air resistance that slows the barrel, and the impact attenuator absorbs residual energy, preventing significant damage to the lightweight robot while maintaining its mobility advantages.
4Object-affected harmful factors
If a recovery system is added to restrain the disrupter barrel, then recoil travel is limited, but the device complexity increases
Solution Approach 1:
The recovery system is segmented into distinct, simple components: a housing mounted on the disrupter barrel, a recovery line extending from the housing, and a separate recovery device at the end of the line. This segmentation allows each component to perform its specific function independently, making the overall system easier to manufacture, assemble, and maintain despite adding functionality to control recoil.
