Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle blade systems fail to automatically maintain the depth of the blade during pitching, which affects the performance when handling different soil types, requiring manual adjustments that can be inefficient and inconsistent.

Innovation Solution

A vehicle equipped with a control system that includes sensors and mechanisms to automatically adjust the blade's depth and pitch by coordinating the lifting and pitching mechanisms, ensuring the blade maintains a consistent depth and pitch during operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the blade is pitched forward and backward to handle different soil types, then the blade's performance is altered, but the blade depth becomes inconsistent requiring manual adjustments

Engineering Contradiction:

Improveblade performance for different soil typesVSAvoidblade depth consistency

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The control system continuously monitors blade depth via sensors and automatically adjusts the lifting mechanism to maintain consistent depth during pitching operations, creating a closed-loop feedback system that eliminates manual adjustments

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs self-adjustment by automatically coordinating lifting and pitching mechanisms through the control system, eliminating the need for manual intervention and allowing the blade to maintain consistent depth while adapting to different soil types

Inventive Principle:

Principle #25Self-service

2Manufacturing precision

If manual adjustments are made to maintain blade depth during pitching, then depth consistency is achieved, but operational efficiency decreases due to frequent interventions

Engineering Contradiction:

Improveblade depth consistencyVSAvoidoperational efficiency

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The blade depth maintenance system operates autonomously by automatically coordinating the lifting and pitching mechanisms through the control system, eliminating manual adjustments and improving operational efficiency

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Sensors provide real-time depth information to the control system, which automatically adjusts the lifting mechanism to maintain consistent blade depth during pitching, creating a self-regulating system that improves productivity

Inventive Principle:

Principle #23Feedback

3Device complexity

If the lifting and pitching mechanisms operate independently, then system complexity is reduced, but coordination between depth and pitch adjustments is lost

Engineering Contradiction:

Improvemechanism coordinationVSAvoidblade depth and pitch control

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The control system merges the operation of the lifting and pitching mechanisms by coordinating their actions based on sensor feedback, ensuring that depth and pitch adjustments work together seamlessly to maintain precise blade control

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A vehicle includes a blade, a lifting mechanism configured to raise and lower the blade, and a pitching mechanism configured to pitch the blade forward and backward. A control system of the vehicle is configured to automatically maintain at least one of a depth of the blade during pitching of the blade and a pitch of the blade during lifting of the blade.
