Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a hydraulic or pneumatic cylinder is used to provide position displacement in a virtual reality experiencing device, then the device can achieve position control and motion simulation, but the operation reaction quickness becomes low and the leftward or rightward rotation is not sensitive
Solution Approach 1:
The patent replaces hydraulic or pneumatic cylinder systems with a direct mechanical drive system consisting of a motor, drive belt, and rotating platform. This substitution eliminates the need for complex fluid control systems while achieving faster response times and more sensitive rotation control through direct mechanical coupling.
Solution Approach 2:
The patent extracts and removes the hydraulic or pneumatic cylinder components from the system, eliminating the associated complexity of fluid control facilities while retaining the essential function of position displacement through a simplified mechanical alternative.
2Ease of operation
If a hydraulic or pneumatic cylinder is used for traveling type experiencing device, then position control is achieved, but the reaction is slow and sliding feeling cannot be provided during curved track travel
Solution Approach 1:
The patent implements a dynamic mechanical system where the rotating platform can continuously adjust its position and orientation in real-time. The direct mechanical drive allows for dynamic response to user inputs, enabling the simulation of sliding sensations during curved track travel through continuous, smooth motion adjustments.
Solution Approach 2:
The patent replaces the slow-responding hydraulic or pneumatic system with a fast-response mechanical drive system that can immediately respond to position control signals, enabling real-time simulation of sliding effects during curved track movement.
3Ease of operation
If a motor and gears are used to provide rotational motion to a user's chair, then the chair can rotate about a vertical shaft, but it takes a long time for the input to be reflected and the motion does not feel like actual traveling
Solution Approach 1:
The patent replaces the gear-based mechanical transmission system with a direct drive system using a motor connected to the rotating platform via a drive belt. This eliminates gear backlash and mechanical delays, resulting in immediate response to user inputs and more realistic traveling sensations.
Solution Approach 2:
The patent removes the gear train from the system, eliminating the time delay associated with gear engagement and mechanical transmission. The direct connection between motor and rotating platform ensures immediate response to control inputs.

Function Achieved in This Case
The device provides a highly realistic virtual reality experience by simulating actual sliding and friction sensations during turns, enhancing user engagement and immersion compared to conventional devices.
Implementation Method 1
a caster brake which is provided above the caster, comes down, thus interrupting the rotation of the caster, so the caster can contact with the upper surface of the belt of a track belt

AI summary
Disclosed herein is a curve cornering simulation device for providing the feeling of friction and sliding when turning, which may include a foot board which is rotatable with respect to a rotary shaft; a pair of pedals which are installed, with the rotary shaft being disposed between the pedals; and a caster which is disposed under the pedals, wherein when a user steps on the pedals, a caster brake which is provided above the caster, comes down, thus interrupting the rotation of the caster, so the caster can contact with the upper surface of the belt of a track belt wherein the belt moves outward of a pair of rollers, and if the foot pedals are stepped on, it can move in the direction where the foot pedals are stepped on.
