Solution Overview

Problem

Current teaching methods in driving schools rely on human coaches who may lack real-time judgment and energy, and unchanging braking programs are not suitable for every vehicle, leading to poor somatic sensation during braking.

Innovation Solution

A braking method and apparatus that generates a braking control signal based on vehicle-specific parameters, collects and evaluates braking data to adjust parameters for improved braking effect and somatosensory feedback, using modules for data collection, evaluation, and parameter determination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an unchanging braking program is used for all vehicles, then the braking system is simple to implement, but the braking effect and somatic sensation are poor due to different braking characteristics of each vehicle

Engineering Contradiction:
Improvebraking program adaptabilityVSAvoidbraking system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The braking program transitions from a static, unchanging sequence to a dynamic, adjustable sequence that adapts to each vehicle's characteristics. The system dynamically modifies braking parameters based on real-time feedback from sensors and evaluation of braking effects, allowing the braking program to evolve and optimize performance for each specific vehicle.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements a closed-loop feedback mechanism where braking data is collected during the braking process, the braking effect is evaluated based on this data, and the braking program is adjusted accordingly. This feedback loop enables continuous optimization of the braking program to match each vehicle's unique characteristics while maintaining system complexity at an acceptable level.

Inventive Principle:
Principle #23Feedback

2Reliability

If a human coach is used to guide and assist braking, then real-time judgment and assistance are provided, but the coach lacks energy for real-time judgment and cannot deal with certain situations in time

Engineering Contradiction:
Improvebraking assistance reliabilityVSAvoidresponse speed
Core Design Contradiction:

Solution Approach 1:

The braking system becomes self-sufficient by automatically collecting braking data, evaluating braking effects, and adjusting the braking program without requiring continuous human intervention. The system serves itself by making real-time decisions based on sensor data and pre-established evaluation criteria, eliminating the limitations of human energy and reaction time while maintaining high reliability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The human coach's mechanical and physiological limitations are replaced by an electronic control system with sensors, processors, and actuators. This substitution enables instantaneous data collection, evaluation, and response without the energy constraints or reaction time delays that affect human coaches, while maintaining or improving braking assistance reliability.

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