Solution Overview
Problem
Existing soil compaction methods using rollers cause surface damage and difficulty in controlling stress and leveling height, especially in clay or loamy soils, and are not suitable for various terrain configurations.
Innovation Solution
A surface compaction method using a compacting tool with a convex sole that rotates and translates parallel to the surface, allowing for controlled compaction with adjustable speed and eccentricity, and optional texturing for improved bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heavy roller compactors are used to compact the surface, then compaction efficiency is improved, but surface flaking and damage occur
Solution Approach 1:
The patent replaces the traditional heavy roller compactor with a rotary blade compactor that uses a rotating blade to compact the surface. This substitution changes the mechanical action from vertical rolling pressure to rotational cutting and scraping action, achieving compaction without the surface flaking caused by heavy rollers. The rotary blade compactor maintains compaction efficiency while eliminating the harmful surface damage.
2Force
If traditional rollers are used for compaction, then compaction force is applied, but control over stress and leveling height becomes difficult
Solution Approach 1:
The patent employs a rotary blade compactor where the blade rotates at controlled speeds and can be adjusted in position. The rotational speed and blade depth can be dynamically controlled to precisely manage the compaction force applied to the surface. This dynamic control mechanism allows operators to easily adjust stress levels and leveling height, overcoming the control difficulties associated with traditional static rollers.
3Adaptability or versatility
If a mounted compacting device is used for versatility, then adaptability to different terrains is improved, but device complexity increases
Solution Approach 1:
The patent designs a mounted compacting device that can be attached to various types of vehicles (tractors, excavators, loaders) to create a universal compaction system. The rotary blade compactor is designed with standardized mounting interfaces and adjustable parameters that allow it to adapt to different terrain configurations and material types. This multi-functional design achieves versatility without requiring separate specialized equipment for each application, thereby limiting the increase in device complexity.
