Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing concrete screed machines struggle to maneuver around obstacles in poured concrete surfaces, requiring significant manual labor and multiple passes, which is inefficient and labor-intensive.

Innovation Solution

A screed apparatus with a telescopic boom assembly and a swing boom system that allows lateral motion, enabling the screed head to move around obstacles without relocating the entire apparatus, using hydraulic actuators and pivot mechanisms for precise leveling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a rigid frame structure with fixed boom is used, then structural stability is improved, but the ability to maneuver around obstacles deteriorates

Engineering Contradiction:

Improvestructural stabilityVSAvoidmaneuverability around obstacles

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The boom is made swingable relative to the frame through a pivot mechanism, transforming the fixed rigid structure into a dynamic one that can adapt its position. This allows the screed head to swing laterally to either side of the boom to navigate around obstacles while maintaining structural stability during operation.

Inventive Principle:

Principle #15Dynamics

2Productivity

If the entire apparatus is relocated to bypass obstacles, then the screeding continuity is improved, but the loss of time increases

Engineering Contradiction:

Improvescreeding continuityVSAvoidtime for relocation

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

Instead of moving the entire apparatus, the boom is made swingable to allow the screed head to laterally position itself around obstacles. This dynamic adjustment eliminates the need for time-consuming relocations of the whole machine, maintaining continuous screeding operation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The screeding function is separated from the main apparatus body by making the boom independently swingable. This segmentation allows the screed head to maneuver around obstacles independently without moving the entire apparatus, thus maintaining continuity without time loss.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If manual finishing is used around obstacles, then the adaptability to obstacles is improved, but the labor intensity increases

Engineering Contradiction:

Improveability to finish around obstaclesVSAvoidlabor intensity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The swingable boom enables the automated screed head to reach and finish concrete surfaces around obstacles independently, eliminating the need for manual finishing operations. This dynamic positioning capability maintains adaptability while significantly reducing labor intensity.

Inventive Principle:

Principle #15Dynamics

AI summary

An apparatus for screeding concrete to produce a level finished surface includes a frame assembly having a front end and rear ends and a pair of spaced vertically oriented stabilization legs supporting a generally horizontal front member. An extendable boom assembly is provided having front and rear ends, and an exterior boom section pivotably secured to the frame assembly proximate said rear end. The extendable boom assembly is also adjustably mounted on said front member to allow generally lateral motion of the boom.
