Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastering machines with fixed upright rails are inconvenient to transport through doorways of standard height due to their fixed length, requiring disassembly which reduces efficiency and increases manufacturing costs with the need for additional components like hydraulic cylinders.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upright rails are made with fixed length to match story height (3 meters), then the plastering machine can operate effectively, but it becomes difficult to transport through doorways (2 meters height) requiring disassembly which reduces working efficiency
Solution Approach 1:
The upright rails are designed with adjustable length through a telescopic structure comprising a first rail segment and a second rail segment that can extend and retract. During transportation, the rails are collapsed to a short length to pass through doorways. During operation, the rails are extended to the required length (3 meters) to match story height, enabling effective plastering operations without disassembly.
Solution Approach 2:
The upright rails are divided into multiple segments (first rail segment and second rail segment) connected by coupling mechanisms. This segmentation allows the rails to be extended to full length for operation and collapsed to short length for transportation, resolving the contradiction between operational effectiveness and transportation convenience.
2Ease of operation
If additional hydraulic cylinders are added to make upright rails adjustable and retractable, then transportation through doorways becomes easy, but manufacturing cost increases
Solution Approach 1:
The rail extension and retraction mechanism is designed to be manually operated without requiring additional hydraulic cylinders or powered assistance. The coupling mechanisms between rail segments allow workers to extend and collapse the rails through simple manual manipulation, reducing manufacturing costs while maintaining transportation convenience.
Solution Approach 2:
Instead of using expensive hydraulic cylinders and complex powered mechanisms, the patent employs simple mechanical coupling components that are cost-effective to manufacture. These basic mechanical elements achieve the desired rail adjustability without the high costs associated with hydraulic systems.
3Ease of operation
If the upright rails are disassembled for transportation, then they can pass through doorways, but the process is inconvenient for workers and reduces working efficiency
Solution Approach 1:
The telescopic rail structure allows the rails to be dynamically adjusted between extended and collapsed states without complete disassembly. The coupling mechanisms enable quick transformation between these states, reducing the time and effort required compared to traditional disassembly methods while maintaining transportation convenience.
Solution Approach 2:
The rail segments are pre-configured with coupling mechanisms that enable rapid extension and collapse. This preliminary design of the telescopic structure eliminates the need for complex assembly procedures, allowing workers to quickly transition between transportation and operational configurations.

Implementation Method 1
The second left rail piece can rotate around a longitudinal tail end of the first left rail piece with respect to the first left rail piece. The second right rail piece can rotate around a longitudinal tail end of the first right rail piece with respect to the second right rail piece.
Implementation Method 2
Each of the left rail and the right rail is provided with a rack. The plastering machine head is provided with a driving gear. The plastering machine head can move up and down along the upright rails through the cooperation between the driving gear and the rack.
