RV Cover Assembly Using Pulling Ropes and Sticks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recreational vehicle covers require users to climb on the vehicle roof for assembly and disassembly, which is hazardous and inefficient, especially for taller and longer vehicles that need two people to manage the cover properly.
Innovation Solution
A recreational vehicle cover design featuring a long rectangle box with downward-extending laces and internal pocket portions with pulling ropes and zippers, allowing two people to assemble and disassemble the cover by standing beside the vehicle, using sticks and pulling ropes to lift and secure the cover without needing to climb on the roof.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional method of climbing on the vehicle roof for assembly and disassembly is used, then the cover can be properly installed and removed, but the operation becomes hazardous and requires specialized access to the vehicle roof
Solution Approach 1:
The patent introduces intermediary elements (pulling ropes, pocket portions, and lifting mechanisms) that mediate between the ground-level operators and the cover on the vehicle roof. These intermediaries transmit forces and enable control without requiring operators to physically climb onto the roof, thus eliminating the safety hazard while maintaining operational capability.
Solution Approach 2:
The cover design incorporates self-lifting and self-positioning mechanisms through the pulling ropes and pocket portions. When operators pull the ropes from ground level, the cover automatically lifts and positions itself onto the vehicle roof without requiring manual placement by climbers, making the system self-servicing and eliminating the need for hazardous roof access.
2Area of stationary object
If the cover is designed for tall and long recreational vehicles, then the coverage and protection are improved, but the assembly and disassembly process becomes more complex and time-consuming
Solution Approach 1:
The patent divides the assembly process into segmented, manageable steps using multiple pulling ropes distributed along the cover and vehicle. Instead of requiring one person to manage the entire large cover, the segmentation allows multiple operators to work independently on different sections, simplifying the overall complex process of assembling a large cover on a tall and long vehicle.
Solution Approach 2:
The patent adds a vertical dimension to the assembly process by incorporating lifting mechanisms that raise the cover from ground level to the vehicle roof. This dimensional change transforms the traditional horizontal spreading operation into a vertical lifting operation, enabling ground-level assembly of large covers on tall vehicles without requiring roof access.
3Quantity of substance
If one person attempts to assemble the cover alone on the vehicle roof, then the labor requirement is reduced, but the difficulty and danger of the operation increases
Solution Approach 1:
The pulling ropes act as intermediaries that distribute the mechanical work of cover assembly across multiple ground-level operators. Each operator manages a specific rope, and their coordinated efforts are transmitted through the ropes to assemble the cover collectively. This intermediary system makes multi-person collaboration as efficient and safe as single-person roof work would have been, if feasible.
4Reliability
If the conventional elastic bands and laces are used to fix the cover, then the cover is tightly secured to the vehicle, but the assembly and disassembly process becomes more time-consuming
Solution Approach 1:
The patent incorporates preliminary positioning actions through the lifting mechanisms and pulling ropes that pre-align the cover with the vehicle before the final securing step. The cover is automatically positioned and roughly aligned during the lifting process, so that when the elastic bands and laces are applied, they can be quickly fastened without requiring time-consuming manual alignment and adjustment, thus maintaining secure fixation while improving assembly speed.
