Solution Overview

Problem

Vehicles create tracks on roads due to repeated travel in the same areas, leading to uneven road wear, increased fuel consumption, and reduced tire efficiency, especially on wet or slippery surfaces.

Innovation Solution

A computer system uses sensors to detect road tracks and issues steering instructions to guide vehicles away from these tracks, maintaining alignment with edges or at a safe distance to prevent tire cooling and improve road wear.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If vehicles drive in the same area of the road, then the vehicle maintains a stable trajectory and easy steering control, but tracks emerge causing uneven road wear and reduced tire efficiency

Engineering Contradiction:
Improvesteering controlVSAvoidtrack formation
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The system uses sensors to detect the position of tracks on the road and provides feedback to the steering arrangement. The processing circuitry continuously monitors the vehicle's position relative to detected tracks and adjusts steering commands accordingly, creating a closed-loop control system that prevents track formation while maintaining stable trajectory.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces purely mechanical steering control with an automated system that uses sensors, processing circuitry, and electronic steering commands. This substitution allows the system to detect tracks and adjust steering position automatically without relying solely on mechanical feedback from the driver.

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

2Ease of operation

If vehicles drive on wet roads in tracks, then the vehicle maintains stable steering, but tires are cooled down increasing fuel consumption

Engineering Contradiction:
Improvesteering stabilityVSAvoidfuel consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system detects track positions using sensors and provides continuous feedback to adjust steering away from wet track areas. This prevents tires from contacting water-filled tracks, maintaining tire temperature and reducing rolling resistance, thereby lowering fuel consumption while preserving steering stability.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If vehicles drive on snowy or muddy tracks, then the vehicle maintains trajectory, but control is reduced due to low friction surface

Engineering Contradiction:
Improvetrajectory maintenanceVSAvoidvehicle control
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system detects snowy or muddy track conditions using sensors and provides feedback to adjust steering away from these low-friction surfaces. By avoiding tracks with poor surface conditions, the system maintains both trajectory stability and vehicle control reliability.

Inventive Principle:
Principle #23Feedback

4Manufacturing precision

If automated steering systems maintain precise trajectory, then the vehicle follows the road accurately, but more tracks are created in the road

Engineering Contradiction:
Improvetrajectory accuracyVSAvoidtrack creation
Core Design Contradiction:
Manufacturing precisionVSObject-generated harmful factors

Solution Approach 1:

The automated steering system uses sensor feedback to detect track positions and adjusts the steering command to intentionally deviate from the center of tracks. This allows the system to maintain accurate trajectory relative to the road while avoiding the harmful effect of creating additional tracks.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system applies different steering control strategies to different locations on the road. When tracks are detected, the system adjusts steering to avoid track centers while maintaining road alignment. This localized adjustment prevents track creation without compromising overall trajectory accuracy.

Inventive Principle:
Principle #3Local quality
