Body Prop Assembly for Tilting Trailer Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vacuum truck systems face limitations in lifting and transporting viscous sludges due to inherent suction limitations, which restrict the length and efficiency of suction hoses, and there is a lack of innovative solutions to enhance the tilting mechanism for trailer assemblies in these systems.
Innovation Solution
A body prop assembly for a tilting trailer assembly that includes a body prop, hinge assembly, and sidetracks, allowing the tilting portions to rotate relative to the trailer platform, with adjustable lower guides that can slide through sidetracks to adjust the body prop assembly between raised and closed configurations, effectively supporting the tilting portions and preventing rotation when lifted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional suction pumps are used, then the system can handle standard liquid volumes, but the suction hose length is limited to approximately 50 meters due to atmospheric pressure limitations
Solution Approach 1:
The pump system is divided into multiple stages, with each stage contributing to the overall pressure reduction. This multi-stage configuration allows the system to achieve deeper vacuums than a single stage could produce, effectively extending the suction hose length beyond the 50-meter limitation while maintaining reliable suction capability for viscous materials.
2Ease of manufacture
If mechanical parts are used in contact with sludge, then the pump design is simpler and costs are lower, but mechanical parts wear and require maintenance
Solution Approach 1:
A sludge package containing a sludge receptacle and filter media is introduced as an intermediary between the mechanical pump components and the sludge. This filter media prevents direct contact between mechanical parts and sludge, significantly reducing wear and maintenance requirements while allowing the pump to handle viscous materials effectively.
3Device complexity
If the tilting mechanism is simplified, then the device complexity is reduced, but the stability and lifting capacity are compromised
Solution Approach 1:
The body prop assembly is designed to be self-positioning and self-locking. As the trailer tilts, the body prop automatically slides along guideways and engages with the tilting portions at the appropriate angle, providing stable support without requiring complex external control systems. The downward force on the body prop assembly causes flaps to close and trap the lower guides, maintaining the tilted position stably.

AI summary
A body prop assembly for supporting portions of a tilting trailer assembly. Said body prop assembly comprising a body prop, a hinge assembly, two sidetracks. Said body prop assembly configured to attach to said tilting trailer assembly between tilting portions and a trailer platform. Said tilting portions selectively rotate with respect to said trailer platform on a tilting hinge. Said tilting hinge defines a tilting axis of said tilting trailer assembly. Said body prop is configured to selectively hold a portion of said tilting portions at an incline. Lower guides are configured to slide through portions of said two sidetracks in order to adjust a lower portion of said body prop assembly. Said body prop comprises an upper portion, a side portions and said lower guides. Said upper portion is substantially parallel with said lower guides.
