Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle arresting device is deployed to stop a fleeing vehicle, then the vehicle can be brought to a controlled stop without serious damage or injury, but the device requires complex setup and deployment mechanisms
Solution Approach 1:
The device is divided into separate functional modules: a launcher assembly for deploying the substrate, a substrate component with weighted plugs and straps, and a control system. This segmentation allows each component to be optimized independently and simplifies the overall deployment process.
Solution Approach 2:
The substrate is pre-configured with weighted plugs attached to corners and straps connected to opposing edges before deployment. This preliminary preparation ensures that when the substrate is launched, it automatically assumes the correct configuration for entangling wheels without requiring complex real-time adjustments.
2Productivity
If the substrate is launched into the path of a fleeing vehicle, then the vehicle can be stopped abruptly, but the timing and positioning must be precisely controlled to ensure safety and effectiveness
Solution Approach 1:
The control system monitors the deployment process and adjusts the launch timing based on feedback from sensors that detect the approaching vehicle's position and speed. This ensures the substrate is launched at the optimal moment for maximum effectiveness while maintaining safety margins.
Solution Approach 2:
The launcher assembly is designed to adjust its aiming angle and launch force dynamically based on the target vehicle's characteristics. The system can adapt to different vehicle types, speeds, and distances, ensuring precise positioning of the substrate in the vehicle's path regardless of varying conditions.
3Force
If the substrate wraps around the front wheels to prevent rotation, then the vehicle stops effectively, but the substrate must be strong enough to withstand the forces without breaking
Solution Approach 1:
The substrate is constructed from high-strength composite materials that provide both flexibility and tensile strength. The combination of durable fabric with reinforced stitching and integrated straps creates a structure capable of withstanding the extreme forces generated when wrapping around moving wheels without breaking.
Solution Approach 2:
The substrate has varying properties in different regions: the central portion is designed to be flexible for wrapping, while the edges with straps and weighted plugs have enhanced strength for anchoring. This local differentiation optimizes the balance between flexibility for engagement and strength for force resistance.
4Object-affected harmful factors
If the device is remotely controlled to launch the substrate, then the operator can stand at a safe location, but the control mechanism adds complexity to the system
Solution Approach 1:
A remote control system serves as an intermediary between the operator and the launcher assembly. This allows the operator to initiate deployment from a safe distance while the control system handles the complex coordination of launching the substrate at the correct time and angle, simplifying the operator's interaction despite the underlying system complexity.

Implementation Method 1
the energy source is a pyro-technic charge that has been inserted into a pressure breech that may be ignited by a spring loaded firing pin that activates a percussion cap
Implementation Method 2
a spring loaded firing pin that activates a percussion cap
Implementation Method 3
The substrate is caused to wrap around the front wheels, the portion of the substrate between the wheels being pulled tight under the vehicle so that the tension in the substrate prevents further rotation of the wheels
Implementation Method 4
the tension in the substrate prevents further rotation of the wheels
