Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a pressing device is used to simulate contact pressure during approach and radius compression, then the force simulation is improved, but the device complexity increases due to the need for release mechanism and stabilization device
Solution Approach 1:
The device is divided into functionally independent modules: a pressing device for simulating contact pressure during approach and radius compression, a release mechanism for simulating take-off, and a stabilization device for maintaining flight phase position. Each module can be controlled independently to reproduce specific phases of the ski jump sequence.
Solution Approach 2:
The pressing device is designed with dynamic control capabilities, allowing the contact pressure to be adjusted and released in real-time during the simulation. The release mechanism enables transition from a pressed state during approach to a released state during take-off and flight phase, reproducing the dynamic force conditions of actual ski jumping.

If the platform is accelerated in vertical direction to simulate approach phase, then the movement sequence simulation is improved, but the ability to simulate take-off and flight phase is limited without release mechanism
Solution Approach 1:
The pressing device is activated before the take-off phase to build up contact pressure and simulate the approach and radius compression conditions. This preliminary action prepares the system for the subsequent release mechanism activation, which then enables the transition to take-off and flight phase simulation.
Solution Approach 2:
The simulation proceeds through distinct periodic phases: the pressing device operates during the approach phase, then the release mechanism activates for take-off, followed by the stabilization device for the flight phase. This periodic activation sequence enables comprehensive simulation of all critical ski jump phases.
3Device complexity
If virtual representation is used for ski jump simulation, then the device complexity is reduced, but the accuracy of force balance simulation is insufficient
Solution Approach 1:
Instead of using virtual representation, the device creates a physical copy of the force conditions experienced during actual ski jumping. The pressing device physically reproduces contact pressure, the release mechanism physically simulates take-off forces, and the stabilization device physically maintains flight phase positioning, providing accurate tactile and force feedback.
Solution Approach 2:
The patent replaces virtual/digital simulation with a mechanical system that physically reproduces the force balance conditions. Mechanical actuators and tensioning devices directly apply forces to the user, substituting computational models with tangible mechanical force application for more realistic training.
