Cavity Cleaning Trailer Lift Assembly for Stable Transit Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for cleaning and coating the interior of cavities, such as manholes, require a dedicated vehicle, which can be expensive and face challenges in accommodating auxiliary equipment and providing stability during transit.
Innovation Solution
A trailer system with a lifting and reclining assembly, comprising a frame, bed, ground engaging elements, and auxiliary equipment assemblies, allows for easy transportation and stable positioning of a cavity cleaning and coating system, including a lifting mechanism to lower and raise the system into and out of cavities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dedicated vehicle is used to transport the cavity cleaning and coating system, then the system can be transported and positioned over cavities, but the cost increases and the vehicle has difficulty accommodating auxiliary equipment and providing stability during transit
Solution Approach 1:
The system is divided into separate components: a trailer for transporting the cavity cleaning and coating system, and a separate vehicle for providing power and operating controls. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining versatility.
Solution Approach 2:
The trailer is designed with a universal platform that can accommodate the cavity cleaning and coating system along with various auxiliary equipment assemblies. The bed structure and lifting mechanism provide multi-functional capabilities for different maintenance operations without requiring a completely different vehicle configuration.
2Ease of operation
If a dedicated vehicle with a long movable arm is used, then the cleaning system can reach cavities, but the vehicle has difficulty providing suitable stability during transit
Solution Approach 1:
The system uses a retractable arm mechanism that can extend and retract based on operational needs. During transit, the arm is retracted to minimize instability, while during operation, it extends to reach cavities. This dynamic adjustment resolves the contradiction between reachability and transit stability.
Solution Approach 2:
The trailer acts as an intermediary platform between the vehicle and the cavity cleaning system. It provides a stable base for the arm mechanism and equipment, isolating the stability requirements from the vehicle during transit while enabling operational positioning when deployed.
3Adaptability or versatility
If a dedicated vehicle is used, then the cleaning system can be transported, but the cost increases
Solution Approach 1:
The transport function is extracted from the vehicle and assigned to a separate trailer. This allows the vehicle to be a standard, less expensive unit while the trailer provides the specialized transport capability needed for the cleaning system and auxiliary equipment.
Solution Approach 2:
The system uses a cost-effective trailer design rather than a expensive dedicated vehicle. The trailer can be a simpler, more economical structure that fulfills the transport requirement without the need for expensive vehicle-grade stability and comfort features.

AI summary
A trailer system for providing transportability for a cavity cleaning and coating system may include a frame, a bed that is attached to the frame, a pair of ground engaging elements that are attached to the frame, and a lifting and reclining assembly that is attached to the frame that is configured to raise and lower the cavity cleaning system into position over a cavity.
