Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a potentiometer sensor is used to measure steering wheel rotation, then the device structure is simple and cost-effective, but the measurement precision is insufficient and mechanical wear occurs

Engineering Contradiction:
Improverotation measurement precisionVSAvoidsensor lifespan
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent replaces the mechanical potentiometer sensor with a magnetic detection system consisting of a magnet fixed to the rotating shaft and a magnetic sensor (such as Hall effect sensor) fixed to the housing. This substitution eliminates mechanical contact and wear, providing non-contact measurement of rotational position with higher precision and reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a magnet as an intermediary element that couples the mechanical rotation to the magnetic sensor. The magnet fixed to the rotating shaft creates a magnetic field that the magnetic sensor detects, enabling precise measurement of rotational position without direct mechanical contact between the sensor and rotating parts.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a fixed steering wheel design is used, then the structure is simple, but the adaptability to different vehicle types is limited

Engineering Contradiction:
Improvecompatibility with different vehicle simulationsVSAvoidcontroller structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the steering controller into separable modules: a base unit with the magnetic detection system and interchangeable actuator components (steering wheels, handlebars, etc.). This segmentation allows users to swap actuators depending on the vehicle type being simulated, enhancing versatility without requiring complete redesign of the entire controller.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent designs the base unit with a universal mounting interface that can accommodate multiple types of actuators (steering wheels for cars, handlebars for motorcycles, etc.). The magnetic detection system and electronic components serve multiple functions across different vehicle simulations, reducing the need for multiple dedicated controllers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of repair

If the actuator is permanently fixed to the base, then the structure is robust, but the ease of repair and recycling is reduced

Engineering Contradiction:
Improvecomponent replacement difficultyVSAvoidconnection robustness
Core Design Contradiction:
Ease of repairVSStrength

Solution Approach 1:

The patent designs the connection between the actuator and base as a separable interface rather than a permanent bond. The actuator can be detached and replaced without damaging the base unit, facilitating easy repair, maintenance, and recycling while maintaining robust connection during normal use through proper mechanical engagement features.

Inventive Principle:
Principle #1Segmentation

AI summary

The controller (1) has an activator (2) that is movable in rotation with respect to a fixed part (3) to simulate control of rotation of a steering column of a simulated vehicle. A detecting unit detects rotational displacement of the activator, where the detecting unit has a magnetoresistive effect or Hall effect detection assembly that comprises a permanent magnet e.g. crown magnet, and a magnetic sensor. The sensor is integrated in rotation to the activator, and the permanent magnet is integrated in rotation to the fixed part. The activator is chosen from a hand wheel, handlebar or ship steering wheel.
