Jig Guide Passage Prevents Semi-Circular Member Misalignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting semi-circular members like thrust bearings and division washers are prone to setting errors, either due to complexity in automated systems or simplicity leading to manual errors, and require a solution to ensure correct orientation and positioning without increasing system size.
Innovation Solution
A jig with a guide passage and protruding portion that ensures correct directional placement of semi-circular members by using an inclined surface to prevent misalignment, featuring a removable side plate and top plate with adjustable apertures and protrusions to accommodate different models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual labor is used to install thrust metal, then the device structure is simple and easy to operate, but setting and positioning errors may occur
Solution Approach 1:
The guide passage serves as an intermediary device between manual operation and precise positioning. It provides a physical constraint that guides the thrust metal into the correct orientation and position, eliminating setting errors while maintaining manual operability. The guide passage structure includes walls that constrain the thrust metal's movement and ensure proper alignment during installation.
Solution Approach 2:
The guide passage enables self-positioning of the thrust metal through its geometric structure. The thrust metal automatically aligns itself with the correct orientation as it passes through the guide passage, without requiring external positioning mechanisms or complex automation. The protrusion and groove features create a self-correcting positioning system.
2Manufacturing precision
If automatic mounting device is used, then setting error is prevented, but the overall system becomes large-scale and complex
Solution Approach 1:
The invention extracts only the essential positioning and guiding functions from a complete automatic mounting system. By isolating the guide passage as a separate, simple component, it provides precise positioning without requiring the complex automation mechanisms, motors, and control systems of a full automatic mounting device.
Solution Approach 2:
The guide passage is designed as a simple, inexpensive fixture rather than a complex automated system. It can be easily manufactured and integrated into existing manual or semi-automatic processes, providing precision positioning without the high cost and complexity of automated mounting equipment.
3Productivity
If the semi-circular member falls directly into the storing groove, then the process is simple, but setting errors and malfunctions occur
Solution Approach 1:
The guide passage performs preliminary positioning and orientation of the thrust metal before it reaches the storing groove. The protrusion and groove features pre-align the thrust metal in the correct orientation during the falling process, preventing setting errors before they occur rather than correcting them after installation.
Solution Approach 2:
The guide passage utilizes curved surfaces and rounded features to guide the thrust metal smoothly into the correct position. The curved bottom surface and rounded protrusions facilitate the rotational movement of the thrust metal as it falls, ensuring proper orientation without requiring complex mechanical positioning mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The jig effectively prevents setting errors by ensuring the semi-circular members are correctly oriented and positioned, reducing the likelihood of misalignment to 90% or more, and can be applied to both manual and automatic mounting processes without increasing system complexity.

AI summary
A protruding portion is formed on a rear side of a side plate, namely a side surface forming guide passage. The protruding portion is intended to prevent a thrust metal from being put to the guide passage with the left and right ends being in the wrong position. Accordingly, a height of the protruding portion is smaller than a depth of the oil ditch of the thrust metal, the width of the protruding portion is smaller than the width of the oil ditch. Also, regarding to the formation position of the protruding portion, when the thrust metal is truly set to guide passage, the center of the protruding portion approximately accords with the center of the oil ditch of the thrust metal.
