Solution Overview

Problem

Autonomous driving systems face challenges in efficiently processing large amounts of data at high speeds, particularly when vehicles are moving at low speeds, where fast reaction times are not as critical, leading to inefficient resource allocation and potential safety risks during high-speed maneuvers.

Innovation Solution

An electronic device that determines the need for high-speed image processing based on the host vehicle's speed, switching between a first image processing module with higher data throughput and a second module with lower data throughput to optimize processing speed according to the vehicle's speed and environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If high-speed image processing is always used, then reaction speed is improved, but resource consumption and processing complexity increase

Engineering Contradiction:

Improvereaction speedVSAvoidresource consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the image processing speed based on the host vehicle's current speed. When the vehicle is moving at high speed, the system uses high-speed processing to ensure fast reaction times. When the vehicle is moving at low speed, the system switches to standard-speed processing to reduce resource consumption. This dynamic adaptation resolves the contradiction by making processing speed variable rather than fixed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the processing parameter (speed mode) based on the vehicle's speed condition. By monitoring the vehicle speed and switching between different processing modes (high-speed vs. standard-speed), the system optimizes the balance between reaction speed and resource consumption according to actual driving conditions.

2Speed

If high-speed image processing is always used, then reaction time is improved, but device complexity increases

Engineering Contradiction:

Improvereaction timeVSAvoidprocessing complexity

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The system implements dynamic processing complexity adjustment by switching between high-speed processing mode and standard processing mode based on vehicle speed conditions. This dynamic approach reduces overall system complexity by only activating high-speed processing when necessary, rather than maintaining it continuously.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the processing parameter (speed mode) based on vehicle speed conditions. By monitoring the vehicle speed and switching between different processing modes, the system optimizes the balance between reaction time and processing complexity, using simpler processing when high speed is not required.

Inventive Principle:

3Use of energy by moving object

If standard image processing is used at low speeds, then resource efficiency is improved, but safety response capability deteriorates in dangerous situations

Engineering Contradiction:

Improveresource efficiencyVSAvoidsafety response capability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The system continuously monitors the host vehicle's speed as feedback and adjusts the processing mode accordingly. This feedback mechanism ensures that when the vehicle reaches speeds where safety becomes critical, the system automatically switches to high-speed processing to maintain adequate safety response capability, thus resolving the contradiction between resource efficiency and safety.

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The system dynamically adjusts data throughput requirements by switching between high-speed processing mode (with higher throughput requirements) and standard processing mode (with lower throughput requirements) based on vehicle speed conditions. This dynamic adjustment optimizes the balance between data processing speed and data throughput requirements.
