Fuel Tank Mounting Clamp for SCR Pipe Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting fuel and SCR reducing agent tanks in vehicles inadequately secure the reducing agent pipe, leading to risks of breakage and rotation during assembly due to insufficient support, particularly with the 'C' clamp design.
Innovation Solution
A method involving a clamp with two arms extending around the fuel filler neck, incorporating a fixing lug with an ear connected to an extension on a gripper arm, which secures the reducing agent pipe to the fuel pipe using a cylindrical pin, eliminating rotational freedom and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a C-clamp is used to connect the reducing agent pipe to the fuel pipe, then the assembly process is facilitated, but the reducing agent pipe is insufficiently supported and at risk of slipping or rotating during capping
Solution Approach 1:
The clamp is divided into two separate arms that can be independently positioned and adjusted. This segmentation allows each arm to be optimized for specific functions: one arm provides support while the other provides locking capability, resolving the contradiction between ease of assembly and pipe stability
Solution Approach 2:
A locking mechanism is introduced as an intermediary element between the clamp arms and the pipe. This mediator component prevents rotation and slippage while maintaining the simple clamp structure, thereby improving reliability without significantly complicating the assembly process
2Object-affected harmful factors
If the reducing agent pipe is made smaller to match the fuel pipe size, then the pipe breakage risk during installation is reduced, but the reducing agent pipe lacks sufficient mechanical resistance and support
Solution Approach 1:
The clamp structure acts as a counterbalancing support system that compensates for the reduced mechanical resistance of the smaller reducing agent pipe. By distributing loads and providing external support, the clamp enables the use of smaller diameter pipes while maintaining sufficient strength and preventing breakage during installation
3Reliability
If the clamp is designed with two arms extending around the filler neck, then the reducing agent pipe is better secured, but the complexity of the mounting structure increases
Solution Approach 1:
The two-arm clamp design merges multiple support functions into a single integrated component. Both arms work together as one unified structure to secure the pipe, providing enhanced reliability without requiring multiple separate mounting elements, thus limiting the increase in overall structural complexity

AI summary
The invention relates to a fuel supply assembly (E2) for at least two consumable fluid reservoirs, comprising pipes (2, 4) connecting a first fuel reservoir to a first filling spout (5) and a second reservoir to a second filling spout (6), each spout (5, 6) being equipped with a mounting bracket (30, 40) on a wall. Furthermore, a support piece (100) incorporates the mounting bracket (30) of the second spout (6) and connects the second spout (6) to the first spout (5) by means of a clamp (31) formed of two arms (32, 33) extending around the first spout (5) in a plane perpendicular (P) to this first spout (5). The fixing bracket (40) of the first chute (5) has an ear (42) connected to an extension (35) formed on an arm (32) of the clamp (31) by fixing means (51), the ear (42) and the extension (35) extending in the plane (P) of the clamp (31).
