Gasoline Delivery Pipe Reinforcement for Flexible Inlet Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing gasoline delivery pipes with pressure pulsation absorbing functions face stress concentration issues at the connecting portion with the inlet pipe, limiting the attachment position and potentially causing damage, which restricts engine layout flexibility.
Innovation Solution
A reinforcing material is applied continuously over the wide walls to suppress bending and stress at the connecting portion between the inlet pipe and the delivery pipe main body, allowing for a more flexible attachment position and reducing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the inlet pipe is connected to the delivery pipe main body at a position where bending deformation occurs, then the attachment position is flexible, but stress concentration occurs at the connecting portion leading to potential damage
Solution Approach 1:
The patent applies local quality by adding reinforcing material specifically at the connecting portion between the inlet pipe and delivery pipe main body. This localized reinforcement strengthens the vulnerable area without affecting the overall flexibility of the delivery pipe, allowing the inlet pipe to be attached at positions with bending deformation while preventing stress concentration from causing damage.
Solution Approach 2:
The patent uses composite materials by combining the delivery pipe main body material with additional reinforcing material at the connecting portion. This composite structure provides both the flexibility needed for attachment position adaptability and the enhanced strength required to prevent damage at the connecting portion under stress.
2Reliability
If the inlet pipe is connected to the end cap or portion near end cap to avoid stress concentration, then the connecting portion is protected from damage, but the attachment position is restricted and engine layout flexibility is reduced
Solution Approach 1:
By applying reinforcement locally at the connecting portion rather than restricting the attachment position to specific areas, the solution allows inlet pipes to be attached anywhere along the delivery pipe main body while maintaining connecting portion strength through the localized reinforcement strategy.
3Reliability
If reinforcing material is applied to suppress bending deformation, then stress at the connecting portion is reduced, but the attachment position freedom is limited
Solution Approach 1:
The reinforcement is applied locally only at the connecting portion between the inlet pipe and delivery pipe main body, not along the entire delivery pipe. This localized approach reduces stress at the critical connecting area while preserving the bending deformation capability and flexibility of the rest of the delivery pipe for attachment position freedom.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The reinforcement effectively reduces high stress at the connection area, preventing damage and offering greater freedom in attaching the inlet pipe, thereby enhancing engine layout characteristics.
Implementation Method 1
the bending deformation of wide walls 33, 34 and narrow walls 35, 36 of the delivery pipe main body 31 lead to stress being concentrated

AI summary
To improve the ability to layout delivery pipes by maintaining flexibility in a mounting position of an inlet pipe to a delivery pipe main body. A delivery pipe for gasoline comprising a flat shaped delivery pipe main body 1 provided with a pair of facing wide walls 2, 3 and a pair of facing narrow walls 4, 5 that are more narrow than the pair of wide walls 2, 3, wherein an inlet pipe 7 is disposed and connected to the narrow wall 4 of the delivery pipe main body 1, and a connecting portion 10 of the inlet pipe 7 and the narrow wall 4 is covered continuously by a reinforcing material 11 from the connecting portion 10 over the wide walls 2, 3, thereby reinforcing the connection portion 10.
