Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete screed machines struggle to maneuver around obstacles in poured concrete surfaces, requiring extensive hand finishing and multiple machine repositions, which is labor-intensive and time-consuming.
Innovation Solution
A concrete screeding apparatus with a telescopic boom assembly and a rigid frame, equipped with a hydraulic system and a side-step system, allowing the screed head to move laterally and pivot around obstacles without relocating the entire machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If prior art screed machines are used to finish concrete surfaces, then the screed head can level large surface areas, but the machine cannot maneuver around obstacles efficiently
Solution Approach 1:
The screed machine is divided into a stationary base and a movable boom assembly with the screed head. This segmentation allows the screed head to be positioned independently around obstacles while the main machine remains stationary, enabling efficient maneuvering without sacrificing productivity.
Solution Approach 2:
The boom assembly is designed with dynamic positioning capabilities, allowing the screed head to move laterally and pivot around obstacles. This dynamic adjustment enables the screed head to access difficult areas around columns, conduits, and other obstacles while maintaining overall machine stability.
2Extent of automation
If prior art screed machines are used, then automated leveling can be achieved, but extensive hand finishing is required around obstacles
Solution Approach 1:
By separating the automated screed head from the main machine body, the system maintains full automated leveling capability while enabling easy manual adjustment around obstacles. The independent boom assembly can be repositioned to reach obstacle-adjacent areas that would otherwise require manual finishing.
Solution Approach 2:
The screed head assembly serves multiple functions: it performs automated leveling across large areas and can be manually repositioned to finish around obstacles. This multi-functionality eliminates the need for separate manual finishing operations by the same operator.
3Adaptability or versatility
If the entire screed machine is repositioned to work around an obstacle, then the obstacle can be finished, but time and labor are consumed
Solution Approach 1:
The machine is segmented into a stationary base and a movable boom assembly. This allows the screed head to be repositioned around obstacles independently, eliminating the need to move the entire heavy machine. The result is significant time savings while maintaining access to obstacle-adjacent areas.
Solution Approach 2:
The boom assembly provides dynamic repositioning capability, allowing rapid adjustment of the screed head position around obstacles without moving the main machine. This dynamic adjustment minimizes downtime and labor while ensuring complete coverage of obstacle areas.

AI summary
An apparatus for screeding concrete to produce a level finished surface includes a frame assembly having a pair of spaced vertically oriented stabilization legs secured to the front end thereof supporting a generally horizontal front member. An extendable boom assembly is secured to the frame assembly at a first end and to a screed head at a second end. A side-step assembly includes an actuator with an extendable arm secured to the boom assembly to impart generally lateral motion.
