Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If existing ski trainer devices are used, then the device structure is simple and easy to operate, but the device cannot simulate extreme body leans and centrifugal forces required for high-speed skiing turns
Solution Approach 1:
A harness system with resilient fasteners acts as an intermediary mechanism between the user and the simulator frame. The resilient fasteners (elastic elements) transmit and simulate centrifugal forces to the user's body, enabling realistic high-speed skiing turn simulation without requiring the entire device structure to be overly complex.
Solution Approach 2:
The resilient fasteners allow dynamic adjustment of force parameters during simulation. By changing the elasticity and tension of the fasteners, the system can simulate varying centrifugal forces corresponding to different skiing speeds and turn radii, enabling parameter-based simulation of real skiing conditions.
2Reliability
If existing ski trainers are used, then the basic movement structure is maintained, but the muscle contraction patterns trained are different from real skiing conditions
Solution Approach 1:
The resilient fasteners in the harness system provide counterbalancing forces that simulate the external forces (gravity and centrifugal forces) acting on a skier during turns. This counterforce mechanism enables users to adopt and maintain extreme body leans characteristic of high-speed skiing, training muscle contractions that accurately reflect real skiing conditions.
Solution Approach 2:
The harness system with resilient fasteners dynamically adapts to user movements during simulation. As users lean into turns, the fasteners adjust their tension and angle, providing continuously varying force feedback that mirrors real skiing dynamics, thereby ensuring accurate muscle contraction pattern training throughout the movement range.
