Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid power assemblies face challenges in achieving a simple, cost-effective, and space-saving method for fixing a first component in the opening of a fluid channel of a second component, as existing solutions are often expensive and occupy significant space.
Innovation Solution
A ring-shaped anchoring element designed as a flat ring disk with a central ring section and anchoring tooth, where the tooth flank directly adjoins the end face without a step, allowing for a low-height, cost-effective fixation by pressing into the fluid channel wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional annular anchoring element with a sleeve-like central ring section and axial steps is used, then reliable anchoring is achieved, but the device occupies significant space and has high manufacturing cost
Solution Approach 1:
The invention transitions from a conventional sleeve-like three-dimensional structure with axial steps to a flat two-dimensional ring disk structure. The anchoring tooth is formed by bending the ring disk radially outward, creating a planar geometry that occupies minimal axial space while maintaining anchoring functionality through the bent tooth configuration.
Solution Approach 2:
The ring disk is designed as a simple, inexpensive flat component that can be easily manufactured and disposed of if necessary. The simplification of the structure from a complex sleeve with multiple steps to a basic bent ring disk reduces manufacturing complexity and cost, making it a more economical anchoring solution.
2Strength
If a conventional annular anchoring element with multiple axial steps is used, then anchoring strength is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The anchoring function is segmented into distinct functional zones: the flat ring disk body provides structural support and positioning, while the radially bent anchoring tooth provides mechanical interlocking. This segmentation allows each zone to be optimized independently - the flat body for ease of manufacture and the bent tooth for anchoring strength.
Solution Approach 2:
The invention changes the geometric parameters from a multi-step axial structure to a planar structure with radial bending. The anchoring tooth is created by bending the ring disk material radially outward, transforming the geometry from vertical steps to horizontal protrusions, which simplifies manufacturing while maintaining strength.
3Stability of the object's composition
If existing anchoring solutions are used, then component fixation is achieved, but the overall assembly size increases
Solution Approach 1:
The invention eliminates axial steps and transitions to a flat ring disk geometry, reducing the assembly from a multi-level vertical structure to a compact planar structure. The anchoring tooth bends radially outward from the flat disk plane, providing fixation without increasing axial height, thus minimizing the overall assembly dimensions.
