Actuated Bushing Assembly Insertion Through a Housing Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for removing and installing bushings into housing openings are inefficient, particularly when dealing with bushing assemblies that include a bushing pin, sleeve, and elastomeric material, as they require manual labor and lack a systematic approach for precise positioning and removal.
Innovation Solution
A bushing displacement system utilizing an actuator and brace assembly, which includes an engaging member and a brace member, allows for the controlled displacement of the bushing assembly relative to the housing opening, enabling precise insertion and removal through a drive system comprising a threaded rod, pullbar socket, and brace nut, facilitating the operation with an actuator to displace the bushing assembly into or out of the structural member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual methods are used to remove and install bushings, then flexibility and simplicity are maintained, but productivity and precision positioning are insufficient
Solution Approach 1:
The bushing assembly is designed with an elastomeric material that provides self-contained support for the bushing pin within the bushing sleeve, eliminating the need for external support structures during installation and removal operations
Solution Approach 2:
The system separates the bushing assembly into distinct components (bushing pin, bushing sleeve, elastomeric material) that can be independently handled, allowing the actuator system to manipulate the entire assembly as a unit while maintaining component integrity
2Manufacturing precision
If traditional pressing methods are used, then simplicity is maintained, but precise positioning control is lost
Solution Approach 1:
The manual pressing operation is replaced with an actuator-driven mechanical system that provides controlled displacement of the bushing assembly through the housing opening, enabling precise positioning without requiring complex alignment procedures
Solution Approach 2:
The engaging member acts as an intermediary between the actuator and the bushing assembly, transferring the actuator's controlled motion to the bushing assembly while the brace member provides structural support and positioning reference
3Reliability
If bushing assemblies with elastomeric material are used, then support and stability are improved, but removal and installation difficulty increases
Solution Approach 1:
The elastomeric material provides self-contained support for the bushing pin within the bushing sleeve, eliminating the need for external support structures during installation and removal operations
Solution Approach 2:
The elastomeric material provides flexible, compliant support that allows the bushing assembly to be dynamically manipulated by the actuator system during installation and removal while maintaining stable support during operation

Implementation Method 1
Operation of the actuator displaces at least one of the brace assembly and the engaging member in the displacement direction relative to the structural member such that the engaging member displaces at least a portion of the bushing assembly towards a desired position relative to the housing opening in the structural member
Implementation Method 2
A bushing displacing system for displacing a bushing assembly relative to a housing opening in a structural member using an actuator and a brace assembly
