Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for changing bearings in internal combustion engines require lifting the engine, making the removal and installation process laborious and inefficient.
Innovation Solution
A tool with parallel mounting plates connected by a turnbuckle and coupling rods, allowing for the removal and installation of bearings without lifting the engine, by tensioning and releasing the damping elements between the securing plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the internal combustion engine is lifted to change a bearing, then the bearing can be removed and installed, but the process becomes laborious and time-consuming
Solution Approach 1:
The patent introduces a tool as an intermediary device between the engine and the bearing. This tool includes mounting plates that attach to the engine mounting frame and a bearing support element that holds the bearing. The tool allows the bearing to be supported and replaced without lifting the engine, thereby resolving the contradiction by making the bearing change process easier and faster.
Solution Approach 2:
The tool is designed to be self-contained with all necessary components (mounting plates, bearing support element, coupling elements) integrated into a single device. The tool can be independently attached to the engine and used to support and replace the bearing without requiring external lifting equipment or additional support structures, enabling the bearing change to be performed efficiently without engine removal.
2Ease of manufacture
If the internal combustion engine is lifted to change a bearing, then the bearing replacement can be performed, but labor requirements increase
Solution Approach 1:
The tool is divided into distinct functional segments: mounting plates for attachment to the engine, a bearing support element for holding the bearing, and coupling elements for connecting the components. This segmentation allows each part to perform its specific function efficiently and makes the overall tool easier to manufacture and assemble while maintaining simplicity in the bearing replacement process.
Solution Approach 2:
The mounting plates are designed with universal attachment capabilities that can accommodate different engine mounting frame configurations. The tool can be used for both supporting the bearing during installation and removing it, providing multi-functionality that reduces the need for multiple specialized tools, thereby simplifying the overall bearing replacement process.
