Solution Overview

Problem

Existing systems for adjusting air deflectors on vehicles require manual driver intervention, which can lead to incorrect adjustments and increased driving costs and safety risks due to distraction during the adjustment process.

Innovation Solution

A vehicle system comprising a camera monitoring system, actuator assembly, and control unit that automatically adjusts the position of an air deflector panel based on captured images and stored data, using an artificial intelligence algorithm to determine optimal positions for different cab-load and cab-trailer combinations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustment of air deflectors is implemented, then the driver can adjust the deflectors according to vehicle setup, but the driver is distracted from primary driving tasks and adjustment may be neglected or incorrect

Engineering Contradiction:
Improveair deflector adjustmentVSAvoidadjustment accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system automatically detects vehicle configuration parameters and adjusts air deflector positions without driver intervention. The control unit processes vehicle data and actuates the deflectors autonomously, eliminating the need for manual operation while ensuring reliable adjustment according to actual vehicle setup

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical adjustment with an automated control system that uses sensors, microprocessors, and actuators. The system substitutes human physical manipulation with electronic control mechanisms that automatically position air deflectors based on detected vehicle parameters

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

2Productivity

If driver interrogation procedure is used during driving, then air deflector settings can be optimized, but driver safety is compromised due to distraction

Engineering Contradiction:
Improvefuel efficiency optimizationVSAvoiddriving safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs aerodynamic optimization autonomously without requiring driver attention. The control unit continuously monitors vehicle configuration and automatically adjusts air deflectors to optimal positions, maintaining fuel efficiency while keeping the driver focused on safe operation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system proactively adjusts air deflectors based on detected vehicle parameters before suboptimal positioning affects fuel consumption. By continuously monitoring and preemptively optimizing deflector positions, the system maintains aerodynamic efficiency without interrupting the driver

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If tabular data with predetermined settings is provided, then adjustment guidance is available, but the settings may not accurately reflect actual vehicle configuration

Engineering Contradiction:
Improveadjustment guidance provisionVSAvoidvehicle configuration matching
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The system continuously detects actual vehicle parameters such as trailer height, cab height, and gap distances, then uses this real-time feedback to automatically adjust air deflector positions. This closed-loop approach ensures settings precisely match the actual vehicle configuration rather than relying on predetermined tables

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically changes air deflector positioning parameters based on detected vehicle configuration variables. By continuously adapting deflector angles and positions to match actual measurements of trailer height, cab height, and gap distances, the system achieves precise configuration matching

Inventive Principle:
Principle #35Parameter changes
