Solution Overview

Problem

Conventional auxiliary brakes for driving training are inconvenient to fasten and unfasten from the brake pedal shaft, often causing obstruction and safety hazards when used by an instructor sitting in the passenger seat.

Innovation Solution

A one-touch type auxiliary brake system featuring a stick member with a handle and a bracket member in the shape of a hollow rectangular frame, allowing the brake pedal shaft to be easily fastened and unfastened using an elastic hinge and magnetic fixation, enabling operation from the passenger seat without direct contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the auxiliary brake is directly fastened to the brake pedal shaft, then the brake can be securely attached, but the fastening and unfastening process becomes complex and time-consuming

Engineering Contradiction:

Improvesecure attachmentVSAvoidfastening and unfastening process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The auxiliary brake device is divided into separate components: a bracket member with a release button and a stick member. The bracket member can be independently attached to the brake pedal shaft, and the stick member can be independently inserted into the bracket member, allowing for simplified fastening and unfastening operations while maintaining secure attachment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bracket member acts as an intermediary between the stick member and the brake pedal shaft. It provides a magnetic coupling interface that simplifies the connection process, allowing the stick member to be easily attached and detached from the brake pedal shaft through magnetic attraction and a release button mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the auxiliary brake is positioned close to the brake pedal shaft for secure attachment, then the attachment is stable, but it causes obstruction between the brake and the user's foot

Engineering Contradiction:

Improveattachment stabilityVSAvoidobstruction and safety hazard

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The bracket member is designed to be installed on the side of the brake pedal shaft rather than directly in front of it, changing the spatial dimension of attachment. This side-mounted configuration maintains stable attachment through magnetic coupling while eliminating obstruction to the driver's foot movement.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Reliability

If the auxiliary brake uses a complex fastening mechanism for secure attachment, then the attachment is reliable, but the device complexity increases

Engineering Contradiction:

Improveattachment reliabilityVSAvoidfastening mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The bracket member and stick member utilize magnetic attraction for automatic alignment and attachment. The magnetic coupling between the bracket member and stick member enables self-aligning connection without complex mechanical fastening mechanisms, reducing device complexity while maintaining reliable attachment.

Inventive Principle:

Principle #25Self-service

AI summary

A one touch type auxiliary brake for driving training is disclosed. The auxiliary brake includes: a stick member having a handle at an end thereof and extendedly provided by a distance from a passenger seat to a brake pedal shaft of a driver's seat; and a bracket member formed in a hollow rectangular frame shape so that the brake pedal shaft is positioned therein, wherein a first plane is fixedly coupled to an opposite end of the stick member, a second plane is provided to be inwardly inclined to allow the brake pedal shaft to be slidable into the rectangular frame when the brake pedal shaft is fastened thereto, and a fourth plane adjacent to an inclined end of the second plane is coupled to an elastic hinge to be rotated outward and returned to its original position when the brake pedal shaft is fastened thereto and unfastened therefrom.
