Partitioned Liquid Trailer Tank for Stable Tongue Weight on Slopes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailers for transporting and applying manure or sewage sludge lack a mechanism to maintain a stable support load during uphill driving, as the liquid shifts and reduces the weight distribution, leading to instability on slopes.
Innovation Solution
A trailer design with a partitioned tank that allows for separate front and rear tank volumes, equipped with adjustable flow openings and a retrofitting cover system to ensure the rear volume is emptied first, maintaining weight distribution and stability by allowing the front volume to support the trailer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tank is divided into separate front and rear volumes with a partition wall, then the tongue weight can be maintained during uphill driving, but the device complexity increases due to the additional partition structure
Solution Approach 1:
The tank is divided into a front tank volume and a rear tank volume by a partition wall. This segmentation allows the liquid to be distributed between the two volumes, ensuring that sufficient weight remains in the front volume to maintain tongue weight during uphill driving, thereby resolving the stability issue on slopes.
2Ease of operation
If the partition wall includes flow openings, then liquid can be freely exchanged between volumes during transport, but the ability to maintain weight distribution is reduced when the openings are open
Solution Approach 1:
The partition wall incorporates flow openings that can be dynamically opened or closed depending on operational requirements. When opened, they allow free liquid exchange between volumes during transport; when closed, they enable separate emptying of the rear volume to maintain weight distribution during application, providing operational flexibility.
Solution Approach 2:
The flow openings in the partition wall can be opened or closed to change the operational state of the system. When closed, the parameter of liquid flow between volumes is changed to zero, allowing independent management of front and rear tank volumes to maintain weight distribution during uphill driving or application.
3Reliability
If the rear tank volume is emptied first during application, then tongue weight is maintained, but the ease of emptying becomes more complex with separate volume management
Solution Approach 1:
The tank is segmented into front and rear volumes with separate outlets, allowing the rear volume to be emptied first through its dedicated outlet. This segmentation simplifies the emptying process by providing independent access to each volume, making it easier to control the sequence of emptying to maintain tongue weight.
Solution Approach 2:
The partition wall with flow openings acts as an intermediary structure that enables separate management of the front and rear tank volumes. It provides the mechanical interface for selective emptying while maintaining the ability to allow liquid exchange when needed, facilitating controlled weight distribution during operation.
