Solution Overview
Problem
Conventional motorcycle simulators lack realism due to constant spring tension, failing to simulate varying riding sensations based on driving parameters like speed and handlebar position.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If spring tension is used to provide resistance, then the structure is simple and reliable, but the tension remains constant and cannot vary with driving parameters
Solution Approach 1:
The patent replaces static spring tension with a dynamic electric motor system that can adjust resistance in real-time based on monitored driving parameters such as handlebar position, throttle grip position, and brake lever position. The motor's torque output varies dynamically to simulate different riding conditions, transforming a static resistance mechanism into an adaptive one.
Solution Approach 2:
The patent substitutes the purely mechanical spring-based resistance system with an electromechanical system. The electric motor, controlled by an electronic circuit that processes sensor inputs, replaces the passive mechanical spring to provide active, parameter-dependent resistance, thereby enabling variability while managing complexity through electronic control.
2Reliability
If the pivot axis is located at floor level, then the structure is stable, but the riding sensations are unrealistic
Solution Approach 1:
The patent relocates the pivot axis from floor level (vertical dimension) to a higher position near the handlebar level (horizontal dimension). This dimensional shift allows the motorcycle assembly to rotate more naturally around a realistic axis, improving riding sensation realism while the electronic control system maintains structural stability through active regulation of motor torque.
Solution Approach 2:
The patent introduces an electronic control circuit as an intermediary between the mechanical structure and the user's riding inputs. This intermediary processes sensor data from multiple riding parameters and dynamically adjusts motor output to maintain stable yet realistic riding sensations, bridging the gap between structural stability and sensation authenticity.
3Measurement precision
If multiple sensors are added to monitor driving parameters, then the control precision is improved, but the device complexity increases
Solution Approach 1:
The patent employs a multi-functional electronic control circuit that simultaneously performs multiple tasks: reading inputs from multiple sensors (handlebar position, throttle grip, brake lever, gear shift pedal), calculating driving parameters, controlling the electric motor's torque output, and monitoring frame inclination. This universal controller consolidates multiple functions into a single integrated system, improving measurement precision while limiting complexity growth through functional integration.

AI summary
Motorcycle simulator, consisting of a frame on which a motorcycle fairing is mounted. Said frame includes footrests with the corresponding gear shift pedal and brake pedal, as well as an angularly movable handlebar equipped with a throttle grip, brake lever, and clutch lever. The frame is rigidly connected to a horizontal and longitudinal profile, which is joined by bearings or bushings to a pair of uprights on which it can tilt, these being associated with a base structure. The horizontal profile is connected, through at least one of its ends, to at least one electric motor controlled by a control circuit. This control circuit is associated with several sensors, specifically: a throttle grip sensor, brake lever sensor, brake pedal sensor, handlebar sensor, clutch sensor, gear shift pedal sensor, and frame inclination sensor. The control circuit includes means for activating the electric motor based on the parameters obtained from the various sensors.
