Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a permanent connection or anchoring is used to securely anchor the vehicle restraint system in the supporting surface, then the restraint effect and safety against severe collisions are improved, but the construction time and complexity increase significantly
Solution Approach 1:
The anchoring system is segmented into a pin component and a blind hole receptacle, allowing the pin to be independently inserted and positioned with specifiable play. This segmentation enables quick assembly without complex permanent anchoring procedures, reducing construction time while maintaining reliability through the pin's frictional engagement within the blind hole.
Solution Approach 2:
The pin is designed with specifiable play relative to the blind hole, creating a dynamic anchoring system that allows controlled movement and tilting during light impacts. This dynamic characteristic reduces construction complexity compared to rigid permanent anchoring while maintaining restraint effectiveness through frictional forces that engage during severe collisions.
2Reliability
If a permanent connection or anchoring is used to securely anchor the vehicle restraint system, then the safety against severe collisions is improved, but the device complexity and material expenditure increase
Solution Approach 1:
The anchoring system is divided into simple components: a pin and a blind hole. This segmentation eliminates the need for complex permanent anchoring structures, reducing device complexity while maintaining safety through the pin's frictional engagement and the concrete barrier wall's structural integrity.
Solution Approach 2:
The pin serves as a simple, replaceable anchoring element that can be quickly installed and removed. This approach reduces device complexity and material expenditure compared to permanent anchoring systems, while still providing adequate safety through frictional forces during severe collisions.
3Reliability
If the vehicle restraint system is securely anchored in the supporting surface, then the restraint effect is improved, but the system becomes stiff and unyielding for light vehicles, increasing impact severity
Solution Approach 1:
The pin's specifiable play relative to the blind hole creates a dynamic anchoring system that permits controlled tilting and movement during light impacts. This dynamic behavior reduces impact severity for light vehicles while maintaining the restraint effect through frictional forces that engage when the pin contacts the blind hole walls during severe collisions.
Solution Approach 2:
The specifiable play parameter of the pin relative to the blind hole is optimized to allow sufficient movement for light impacts to reduce impact severity, while ensuring adequate engagement to maintain restraint effect during severe collisions. This parameter adjustment resolves the contradiction between restraint effectiveness and impact severity.
4Reliability
If the vehicle restraint system is securely anchored in the supporting surface, then the restraint effect is improved, but no tilting effects can be utilized to reduce impact energy
Solution Approach 1:
The pin's specifiable play enables the concrete barrier wall to tilt and rotate during impacts, utilizing gravitational potential energy and kinetic energy dissipation through movement. This dynamic anchoring allows energy dissipation mechanisms while maintaining restraint effect through frictional forces that engage during severe collisions.
Solution Approach 2:
The specifiable play of the pin relative to the blind hole provides beforehand cushioning by allowing controlled movement and tilting during light impacts, dissipating impact energy through mechanical work before the pin engages firmly with the blind hole walls during severe collisions.
