Bridge-Structured Mounting Bush for Multi-Directional Load Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting bushes for electric compressors suffer from large bending angles and strains due to their integral structure, which makes them inefficient in withstanding external forces applied in various directions.
Innovation Solution
The mounting bush is designed with X-axis and Z-axis bridges formed on opposite sides of the inner and outer pipes, each supporting horizontal and vertical loads respectively, and are spaced apart in the Y-axis direction, allowing for asymmetric design and enhanced elasticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the rubber is formed in an integral structure, then the manufacturing process is simple, but the bending angle and strain are large
Solution Approach 1:
The rubber is divided into multiple independent bridges (first bridge for X-axis loads, second bridge for Z-axis loads) instead of using an integral structure. Each bridge is configured to specifically withstand loads in particular directions, thereby reducing bending angles and strains while maintaining manufacturing feasibility through modular construction
2Reliability
If the mounting bush is designed for a specific direction, then it can withstand forces in that direction well, but it cannot optimally handle forces from other directions
Solution Approach 1:
Different bridges are designed with specific geometries and material properties optimized for their respective load directions. The first bridge is configured for horizontal (X-axis) loads while the second bridge is configured for vertical (Z-axis) loads, allowing each component to have localized characteristics that maximize performance in its specific function while collectively providing multi-directional capability
Solution Approach 2:
The mounting bush incorporates multiple bridges that collectively provide universal load-bearing capability in multiple directions. Each bridge specializes in a particular direction, but together they enable the mounting bush to handle forces from various directions optimally, achieving multi-functionality without requiring separate components for each direction

Function Achieved in This Case
This design minimizes bending moments and disperses durable loads, reducing deformation and damage from various directional forces, thereby enhancing durability and design flexibility.
Implementation Method 1
an X-axis bridge formed on each opposite side between the inner side surface and the outer side surface such that the X-axis bridge elastically supports against a horizontal load
Implementation Method 2
a Z-axis bridge which is formed in a direction perpendicular to the X-axis bridge and which is formed on each opposite side between the inner side surface and the outer side surface such that the Z-axis bridge elastically supports against a vertical load

AI summary
Proposed is a mounting bush including an inner pipe, an outer pipe, and a rubber mounted between the inner pipe and the outer pipe. The rubber includes an inner side surface formed along an outer circumferential surface of the inner pipe, an outer side surface formed along an inner circumferential surface of the outer pipe, and a bridge connecting between the inner side surface and the outer side surface. The bridge includes an X-axis bridge formed on each opposite side between the inner side surface and the outer side surface such that the X-axis bridge elastically supports against a horizontal load, and a Z-axis bridge which is formed in a direction perpendicular to the X-axis bridge and which is formed on each opposite side between the inner side surface and the outer side surface such that the Z-axis bridge elastically supports against a vertical load.
