Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid and inflexible hurdles are used for training, then the hurdles provide structural stability and realism, but they cause injuries and fear of contact leading to altered routines and reduced speed
Solution Approach 1:
The hurdle barrier is transformed from a rigid static structure to a dynamic flexible structure. The barrier includes a flexible rod that can bend and deform under load, allowing it to adapt to contact forces while maintaining structural integrity. This dynamic characteristic enables the hurdle to absorb impact energies without causing injuries, while still providing realistic training conditions.
Solution Approach 2:
The barrier is constructed using flexible materials such as a flexible rod enclosed within a flexible tubular coupler. This flexible shell structure maintains the hurdle's shape and stability while allowing controlled deformation during contact. The flexible rod can bend to accommodate impact forces, preventing the sharp edges and rigid contact points that cause injuries in traditional hurdles.
2Stability of the object's composition
If rigid hurdles are used, then the hurdles maintain their shape and position, but they cause fear of hitting and tripping leading to altered running routines
Solution Approach 1:
The physical parameters of the barrier are changed from rigid to flexible. The flexible rod and tubular coupler allow the barrier to change shape controlledly under load while returning to its original position. This parameter change enables the hurdle to maintain stability during non-contact phases while providing safe, natural contact during practice, eliminating fear and allowing athletes to maintain natural running routines.
3Object-affected harmful factors
If flexible materials are used for the hurdle, then the risk of injury is reduced, but the structural stability and realism may be compromised
Solution Approach 1:
The barrier employs a composite structure combining a flexible rod within a flexible tubular coupler. This composite design provides both flexibility for safety and structural stability for realism. The combination of these flexible components creates a barrier that maintains its shape and position during normal operation while allowing controlled deformation during contact, achieving both safety and structural reliability.
Solution Approach 2:
The flexible rod and tubular coupler create a dynamic structure that adapts to loading conditions. During normal operation, the structure maintains its rigid-like stability. During contact, it deforms controlledly to absorb impact, then returns to its original position. This dynamic behavior provides both structural stability for realism and flexibility for injury prevention.
4Reliability
If professional athletes practice with rigid hurdles, then they can maintain competition-like conditions, but they risk hamstring injuries from metal bases and sharp corners
Solution Approach 1:
The barrier uses a flexible rod enclosed in a flexible tubular coupler, creating a flexible shell structure that eliminates exposed metal bases and sharp corners. This flexible enclosure maintains the hurdle's competition-like appearance and stability while removing the harmful rigid elements that cause hamstring injuries during lead leg practice drills.

AI summary
A hurdle assist includes a flexible tubular lower section comprising a first length and a first slit along the first length, a flexible tubular upper section comprising a second length and a second slit along the second length, and a flexible rod which is slidably removably coupled with the flexible upper section. Attaching the hurdle assist to a hurdle mimics a flexible hurdle for the runner to practice without fear of injury.
