Pipe Connection Joint With Linear Slant Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe connection joints require expensive materials and additional machining processes, leading to increased manufacturing costs and complexity, especially in restricted spaces like vehicle engines, due to the need for reinforcing ribs and multiple flange designs to accommodate varying mounting directions and sealing member seating processes.
Innovation Solution
A pipe connection joint featuring a flange with a linear slant portion and an expandable pipe portion that expands along this slant to increase contact area, allowing for firm fixation and rotation prevention without additional machining, and utilizing micro R bending technology for space efficiency, with a sealing member seating portion formed by the pipe-expanded portion to minimize manufacturing expenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforcing ribs are added to increase joining strength, then the joining force between flange and pipe is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The invention extracts and eliminates the reinforcing ribs from the flange structure. Instead of adding ribs to strengthen the connection, the patent uses a different approach by forming an expanded portion directly on the pipe that interfaces with the flange, thereby achieving strong joining without the complex ribbed structure.
Solution Approach 2:
The invention replaces expensive and complex reinforcing ribs with a simpler pipe expansion structure. The expanded portion of the pipe serves as the strengthening element, eliminating the need for additional rib components and reducing overall manufacturing cost and complexity.
2Adaptability or versatility
If multiple flange designs are created for different mounting directions, then adaptability to various mounting orientations is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The invention creates a universal flange design that can accommodate pipes bent in different directions. The flange structure with its pipe joining hole and linear slant portion can universally accept pipes oriented in various directions, eliminating the need for multiple specialized flange designs for different mounting orientations.
Solution Approach 2:
Instead of adapting the flange to different pipe orientations through multiple designs, the invention inverts the approach by making the pipe itself adaptable through bending. The pipe is bent to match the mounting direction while the flange remains a standardized design, reducing flange variety requirements.
3Reliability
If additional machining processes are performed for seating sealing members, then sealing reliability is improved, but manufacturing cost and process complexity increase
Solution Approach 1:
The invention performs preliminary action by forming the sealing member seating portion simultaneously with the pipe expansion process. The seating portion is created as part of the expansion operation before final assembly, eliminating the need for separate machining steps and reducing manufacturing complexity while ensuring proper sealing surfaces.
Solution Approach 2:
The invention merges the sealing member seating portion formation with the pipe expansion process. Both the expanded portion for structural connection and the seating portion for sealing are created in a single integrated operation, reducing the total number of manufacturing steps while maintaining sealing reliability.
4Volume of moving object
If micro R bending technology is used to minimize bending distance, then space efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The invention applies parameter changes by using micro R bending technology to dramatically reduce the bending radius of the pipe. This allows the pipe to achieve the necessary spatial configuration in a compact form factor, minimizing the bending distance and space required while maintaining manufacturability through controlled deformation parameters.
