Solution Overview

Problem

Existing speed controllers for video games are complex, costly, and lack ergonomic design, particularly in transitioning between manual and sequential modes, and do not effectively simulate the realism of vehicle speed control devices.

Innovation Solution

A speed controller with a pivoting lever and detection means that allows operation in both manual and sequential modes, utilizing a grid system with transverse and longitudinal slots, and elastic return mechanisms to simplify component count and enhance ergonomics, eliminating the need for longitudinal elastic return means in sequential mode by leveraging transverse elastic return.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If longitudinal elastic return means are added to enable sequential mode operation, then the speed controller can detect positions in sequential mode, but the number of components and cost increase

Engineering Contradiction:
Improvemode operation capabilityVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transverse elastic return means are designed to perform dual functions: returning the lever to neutral position in manual mode and enabling sequential mode operation. This eliminates the need for separate longitudinal elastic return means, reducing component count while maintaining both operational modes

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

Solution Approach 2:

The patent combines the functions of transverse elastic return means and longitudinal elastic return means into a single transverse elastic return mechanism. The grid geometry is modified to allow the same elastic mechanism to constrain lever movement in both transverse and longitudinal directions during sequential mode, merging previously separate functions into one component

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If a grid with multiple longitudinal slots is used for manual mode, then the lever can be guided to multiple positions, but the device size increases

Engineering Contradiction:
Improvelever position controlVSAvoidcontroller size
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The grid is designed with selective slot availability based on operating mode. In sequential mode, only the transverse slot is accessible, limiting lever movement to a smaller range. In manual mode, longitudinal slots become accessible for multi-position control. This dynamic adaptation allows compact design while maintaining full functionality

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The grid is segmented into distinct functional areas: a transverse slot for sequential mode operation and longitudinal slots for manual mode. This segmentation allows the same physical grid structure to serve multiple purposes with different spatial requirements, optimizing overall controller size

Inventive Principle:
Principle #1Segmentation

AI summary

The controller has a support casing (1), and a lever (2) hingeably mounted around a longitudinal axis with respect to the casing. The lever pivots, from a neutral position, in a transversal direction around the axis. A detection unit detects two different positions of the lever obtained by pivoting the lever around the axis from the position in a speed selection mode i.e. manual mode, where the controller operates according to handbrake mode. The lever swivels around the axis between two braking positions corresponding to absence of braking and a maximum braking in the mode.
