Solution Overview

Problem

Existing soil compactors with soil radar density measuring arrangements are vulnerable to external damage from obstacles and cleaning operations, compromising their functionality and reliability.

Innovation Solution

The soil radar density measuring arrangements are housed within the inner volume regions of the compactor frame, protected by elastic suspension elements and accessible via inspection openings, allowing for maintenance and protection against external impacts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the soil radar density measuring arrangement is positioned on the compactor frame to detect soil moisture content, then the measurement function is achieved, but the arrangement is vulnerable to damage from obstacles and cleaning operations

Engineering Contradiction:

Improveprotection of soil radar density measuring arrangementVSAvoiddamage from obstacles and cleaning operations

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The soil radar density measuring arrangement is positioned inside the compactor frame, nesting the measurement device within the structural framework. This protects the radar arrangement from external obstacles and cleaning operations while maintaining its ability to detect soil moisture content through the frame walls.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The compactor frame acts as an intermediary structure that shields the soil radar density measuring arrangement from direct exposure to harmful external factors. The frame serves as a protective barrier between the radar device and obstacles or cleaning operations, while still allowing the radar to perform its measurement function.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the soil radar density measuring arrangement is protected within the compactor frame, then protection from external damage is achieved, but accessibility for maintenance may be reduced

Engineering Contradiction:

Improveprotection from external damageVSAvoidaccessibility for maintenance

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The compactor frame is designed with segmented or modular characteristics that allow for controlled access to the soil radar density measuring arrangement. The frame structure incorporates features such as removable panels or accessible compartments that enable maintenance personnel to reach the radar device for maintenance while maintaining overall protection during operation.

Inventive Principle:

Principle #1Segmentation
