Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a VR treadmill is used, then users can exercise in a virtual environment, but the ground conditions of the virtual reality environment cannot be simulated
Solution Approach 1:
The patent applies the dynamics principle by making the exercise platform movable and adjustable to simulate different terrain conditions. The platform can dynamically change its state to represent various ground conditions such as hills, valleys, and uneven surfaces, allowing users to experience realistic terrain variations while exercising in a VR environment.
Solution Approach 2:
The patent uses the copying principle by creating a physical model of virtual terrain environments. The exercise platform replicates the ground conditions of virtual reality environments through mechanical structures that mimic hills, slopes, and other terrain features, thereby bridging the gap between virtual and physical experiences.
2Adaptability or versatility
If existing VR treadmills are used, then simple exercises can be performed, but complex terrain simulations are not achievable
Solution Approach 1:
The patent applies segmentation by dividing the exercise platform into multiple independent modules that can be controlled separately. This allows complex terrain simulations to be achieved through coordinated movement of individual segments, enabling realistic terrain representation while maintaining manageable system complexity through modular design.
Solution Approach 2:
The patent implements multi-functionality by designing a universal exercise platform that can simulate various terrain conditions and support multiple exercise types. The same platform structure serves multiple purposes including walking, running, climbing, and other exercises across different virtual environments, thereby achieving high adaptability without proportionally increasing complexity.
3Reliability
If terrain simulation is added to VR exercise machines, then the sense of reality is improved, but the device complexity increases
Solution Approach 1:
The patent applies feedback by incorporating sensors that detect user position, movement, and terrain contact information. This feedback is used by the control system to adjust the exercise platform in real-time, ensuring accurate terrain simulation while adapting to user actions. The feedback mechanism enables sophisticated control through intelligent adjustment rather than overly complex mechanical systems.
