Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel distributors with forged pressure accumulator tubes face challenges in production technology and weight due to unequal mass distribution and long protruding connecting pieces, which complicate processing and increase weight, especially during deep-hole drilling and mounting.
Innovation Solution
A fuel distributor with a forged base body featuring integrated flange sections and separate sleeves providing a compact design, eliminating long connecting pieces and internal stresses, and using deep-hole drilling for the longitudinal cavity, with sleeves pressed into the flange sections for a reliable connection, and integrally formed injector flanges for space-saving stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If long protruding connecting pieces are used to mount the fuel distributor, then the mounting flexibility and reach are improved, but the weight increases and the processing complexity increases
Solution Approach 1:
The patent transitions from long protruding connecting pieces extending radially outward to integrated flange sections with mounting holes in the cylindrical wall, effectively changing the dimensional approach from external extensions to surface-mounted features on the main body.
Solution Approach 2:
The invention extracts the connecting piece function from separate long protruding elements and integrates it directly into the fuel distributor body through flange sections, eliminating the need for separate mounting arms or extensions.
2Length of stationary object
If long protruding connecting pieces are used, then mounting reach is improved, but the processing difficulty increases due to unequal mass distribution
Solution Approach 1:
The patent changes the geometric approach by creating mounting flanges on the cylindrical surface rather than extending long connecting pieces, maintaining mounting reach while preserving rotational symmetry for easier machining.
Solution Approach 2:
The invention introduces asymmetry only where needed (in the flange section geometry for mounting) while maintaining overall symmetry in the base body, allowing standard machining operations without the complications of highly asymmetric mass distribution.
3Adaptability or versatility
If forged connecting pieces with long protrusions are used, then mounting flexibility is improved, but internal stresses increase causing adverse effects during mechanical processing
Solution Approach 1:
The invention extracts the mounting function from separate forged connecting pieces and integrates it into the main body through flange sections, eliminating the stress concentration zones that would exist at the junctions of separately attached connecting pieces.
Solution Approach 2:
The patent merges the mounting feature integration directly into the base body forging process, creating a unified structure without separate connecting pieces, thereby eliminating internal stresses at interfaces between different components.
4Manufacturing precision
If separate fastening pieces with guide sleeves are used, then mounting precision is improved, but the device complexity and manufacturing steps increase
Solution Approach 1:
The invention merges the guide sleeve function and mounting hole features directly into the flange section of the base body, eliminating separate fastening pieces and reducing the total number of components while maintaining mounting precision.
Solution Approach 2:
The flange section serves multiple functions: providing mounting surface, containing guide features for alignment, and incorporating mounting holes, thereby replacing multiple separate components with a single multi-functional integrated structure.
