Solution Overview

Problem

Existing vehicle launch systems lack the ability to dynamically adjust acceleration based on real-time road conditions and detect potential obstacles in the launch path, which can lead to unsafe acceleration and potential collisions.

Innovation Solution

A system that uses a processor and sensors to determine a vehicle launch path based on specified speed and physical attributes, adjusts acceleration based on ground surface friction, and deactivates the launch if an object is detected within the path or predicted to be an obstacle, using a combination of sensor data and collision likelihood estimation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the vehicle accelerates at maximum predetermined acceleration in launch mode, then the vehicle reaches specified speed quickly (improving productivity), but the vehicle may collide with objects in the launch path or unsafe acceleration may occur (worsening reliability)

Engineering Contradiction:

Improveacceleration speedVSAvoidcollision safety

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary detection of the launch path for objects before initiating maximum acceleration. The processor identifies the launch path and detects objects within it before the vehicle begins accelerating, allowing the system to prevent collision by adjusting acceleration or routing before the harmful event occurs.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the launch path during acceleration using sensors, and dynamically adjusts acceleration based on detected objects. When an object is detected in the launch path, the system provides feedback to reduce acceleration or change direction, ensuring safety while maintaining performance when the path is clear.

Inventive Principle:

Principle #23Feedback

2Ease of operation

If the vehicle uses a fixed predetermined acceleration in launch mode, then the control system is simple (improving ease of operation), but the system cannot adapt to changing road conditions or detect obstacles (worsening adaptability)

Engineering Contradiction:

Improvelaunch control simplicityVSAvoidroad condition adaptation

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system transitions from static predetermined acceleration to dynamic adaptive acceleration. The processor continuously adjusts acceleration based on real-time sensor data about road conditions and detected objects, allowing the vehicle to adapt its launch parameters dynamically while maintaining automated control.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses its own sensor data and processing capabilities to automatically detect road conditions and objects, then self-adjusts acceleration without external input. The vehicle's computer system serves itself by making real-time decisions about launch parameters based on environmental feedback.

Inventive Principle:

Principle #25Self-service
