Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete screeding technologies are cumbersome, heavy, and lack maneuverability, leading to uneven finishes and high emissions, particularly in enclosed spaces like upper deck pours, where they struggle to maintain consistent leveling and are hindered by weight and complexity.
Innovation Solution
A lightweight, maneuverable screed apparatus with a frame assembly and drive system, featuring a screed head with adjustable leveling and a power system that can perform zero-radius turns, powered by internal combustion or electrical systems, and equipped with sensors for continuous leveling and reduced emissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional screeding machines are used, then screeding capability is provided, but weight and maneuverability deteriorate
Solution Approach 1:
The screed is divided into separate modular components including a screed head assembly, frame assembly, and leveling system that can be independently adjusted and positioned, allowing the machine to be lighter while maintaining functionality through modular configuration
Solution Approach 2:
The screed incorporates a dynamically adjustable leveling system with movable screed head and adjustable frame components that adapt during operation, enabling the lightweight structure to maintain consistent leveling performance despite reduced weight
2Power
If heavy machinery is used, then screeding power is sufficient, but emissions increase in enclosed spaces
Solution Approach 1:
The screed replaces traditional internal combustion engine power systems with alternative power sources that eliminate exhaust emissions, allowing sufficient screeding power to be delivered without generating harmful emissions in enclosed construction spaces
Solution Approach 2:
The power delivery parameters are optimized to provide adequate screeding force through efficient mechanical transmission and optimized contact pressure, reducing the need for high-power combustion engines that generate emissions
3Manufacturing precision
If complex automated systems are used, then screeding precision is improved, but device complexity increases
Solution Approach 1:
The screed incorporates self-leveling mechanisms and automatic adjustment systems that maintain consistent leveling without requiring complex external control systems, achieving precision through self-regulating mechanical designs
Solution Approach 2:
The leveling system uses adjustable parameters and configurable settings that allow precise control of screeding operations through simple mechanical adjustments rather than complex automated controls, maintaining precision while reducing system complexity
