Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing line bushings are difficult to install in passage openings that are tilted or oblique, particularly due to the risk of contamination and complexity in handling joints with abutting faces.
Innovation Solution
A line bushing with a tiltably mounted bushing sleeve and elastomeric joint allows for installation in tilted passage openings, featuring symmetrical tiltability and a monolithic construction with elastomer material, including projections and indentations for deformation, and a filling substance injection system through an annular space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a joint with abutting faces (e.g., spherical ball joint) is used to enable tiltability, then the ability to install in tilted passage openings is improved, but the risk of contamination increases and handling/assembly becomes more complex
Solution Approach 1:
The patent employs an elastomeric deformation element (flexible element) as the joint between the bushing sleeve and flange part. This elastomeric component allows tiltability through elastic deformation rather than mechanical abutting faces, eliminating contamination risks associated with traditional joint surfaces while maintaining the ability to accommodate tilted passage openings.
2Adaptability or versatility
If a joint with abutting faces (e.g., spherical ball joint) is used to enable tiltability, then the ability to install in tilted passage openings is improved, but the complexity of handling and assembly increases
Solution Approach 1:
The elastomeric deformation element provides a simple, single-component solution that replaces complex mechanical joint assemblies. The flexible element inherently provides the tiltability function through its elastic properties, eliminating the need for multiple components, precise machining of joint faces, and complex assembly procedures.
3Object-affected harmful factors
If an elastomeric joint is used to enable tiltability, then contamination risk and assembly complexity are reduced, but the structural complexity of the bushing increases
Solution Approach 1:
The elastomeric deformation element is integrated as an inherent part of the bushing structure, merging the joint function with the bushing body. This integration approach, where the flexible element is molded or formed as part of the overall bushing assembly, reduces structural complexity compared to adding a separate joint mechanism.
4Ease of operation
If the bushing sleeve is made tiltably mounted via elastomeric joint, then ease of installation in tilted passages is improved, but the precision of alignment may be affected
Solution Approach 1:
The elastomeric deformation element changes its physical parameters (shape, orientation) through elastic deformation to accommodate tilted installation angles. This parameter change allows the bushing sleeve to be installed in tilted passages while the elastomeric joint compensates for misalignment, effectively decoupling installation ease from alignment precision requirements.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and robust installation in tilted passages with reduced contamination risk, simplified assembly, and efficient filling substance distribution, ensuring secure fastening and sealing.
Implementation Method 1
the tiltability is realized via an elastomeric joint, that is to say with an elastomeric deformation element as a joint
Implementation Method 2
a flowable filling substance is supplied to the supply volume of the bushing sleeve, which flowable filling substance penetrates at least proportionally into the filling volume via the exit opening
