Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing simulation devices lack the ability to allow users to easily control complex actions using two feet, limiting the sense of reality and variety of actions in virtual reality games and simulations.
Innovation Solution
An operation pedal with a stationary shaft, pedal main body, and foothold that can be turned in multiple directions, equipped with sensing mechanisms to transmit signals for forward, rearward, leftward, and rightward movements, allowing independent control of each pedal and combination of control signals for diverse actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simulation device uses traditional joystick or keyboard-mouse control, then the device structure remains simple, but the sense of reality is greatly deteriorated and users cannot experience actual situation phenomena
Solution Approach 1:
The patent creates a virtual copy of actual driving operations through the simulation device. The operation pedals replicate the functional characteristics of real car pedals (accelerator, brake, clutch) and the simulation chair reproduces the seating position and body orientation of actual driving, allowing users to experience a sense of reality without requiring the actual vehicle structure
Solution Approach 2:
The patent replaces complex mechanical driving systems with electronically controlled simulation components. Instead of requiring actual engine, transmission, and suspension systems, the invention uses electronic sensors, actuators, and control systems to simulate the mechanical sensations and responses of real driving operations
2Adaptability or versatility
If the simulation device provides only simple two-hand operation control, then the device complexity remains low, but the variety of actions that can be performed is limited
Solution Approach 1:
The patent divides the control system into multiple independent operational segments: operation pedals for acceleration/braking/clutch control, simulation chair for positioning and orientation, and coordinated control mechanisms. This segmentation allows each component to handle specific actions independently while combining to produce complex coordinated maneuvers, greatly expanding the variety of performable actions
Solution Approach 2:
The operation pedals serve multiple functions beyond simple acceleration and braking. They are designed to handle clutch operation, coordinated multi-pedal maneuvers, and various driving scenarios (starting, stopping, turning, emergency braking), making a single control mechanism universally applicable to diverse driving actions and situations
3Reliability
If the simulation device uses fixed pedal position, then the ease of operation is maintained, but the ability to reproduce dynamic changes and sense of reality is limited
Solution Approach 1:
The patent implements dynamic adjustment capabilities in the simulation chair and operation pedals. The chair can dynamically change position, orientation, and vibration characteristics to match driving conditions. The pedals can dynamically adjust resistance, position, and response characteristics, allowing the system to adapt to various driving scenarios while maintaining operational intuitiveness
