Concrete Curing Machine Texturing and Spraying Device Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete surface treatment machines require time-consuming conversions to switch between texturing and spraying tasks, and the mass inertia of the machine frame causes pitching movements that alter the engagement height of texturing tools during acceleration and braking, leading to inconsistent surface treatment.
Innovation Solution
The machine is designed with both longitudinal and transverse texturing and spraying devices that can be moved independently and pivoted to avoid collisions, allowing for quick conversion between tasks and minimizing the impact of machine frame movements on tool height, using a system of rail guides and quick-change tools to facilitate efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the machine is equipped with both longitudinal and transverse texturing devices that can be moved independently, then the adaptability and versatility of the machine is improved, but the device complexity increases
Solution Approach 1:
The machine frame is designed with universal mounting capabilities that allow the same structural elements to support different types of working devices (longitudinal texturing, transverse texturing, spraying). The machine can perform multiple functions by configuring different working devices on the same frame without requiring complete redesign, thereby achieving versatility while controlling complexity.
Solution Approach 2:
The working devices are designed with movable and adjustable characteristics, allowing them to be positioned, rotated, or removed as needed. This dynamic configuration capability enables the machine to adapt to different task requirements while maintaining a relatively simple base structure, resolving the contradiction between versatility and complexity.
2Ease of operation
If the texturing devices are positioned in front of or behind the machine frame, then the ease of operation is improved, but the reliability of consistent texturing height deteriorates due to pitching movements during acceleration and braking
Solution Approach 1:
The longitudinal texturing device is positioned at the center of gravity of the machine frame in the longitudinal direction. This central positioning creates an equipotential condition where pitching movements during acceleration and braking do not create significant height variations at the texturing point, ensuring consistent engagement height while maintaining operational convenience.
Solution Approach 2:
The machine frame design incorporates counterbalancing considerations where the positioning of working devices and mass distribution are optimized to minimize the effect of inertial forces during dynamic operation. By strategically positioning the longitudinal texturing device at the center of gravity, the design counteracts the adverse effects of pitching movements on texturing consistency.
3Ease of manufacture
If conversion kits are kept separately for different texturing configurations, then the ease of manufacture is improved, but the loss of time increases due to time-consuming conversions
Solution Approach 1:
The machine frame is pre-designed with integrated mounting provisions and standardized interfaces for different working devices during the initial manufacturing process. This preliminary preparation of the frame structure eliminates the need for time-consuming field conversions, as all necessary mounting points and support structures are already in place, allowing quick configuration changes by simply installing or removing working devices.
