Segmented Locating Pin for Vehicle Panel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locator pins used in vehicle assembly are difficult to remove after panel installation, leading to aesthetic issues and the need for additional trim components to cover them.
Innovation Solution
A locating and retention pin system with a first and second portion, where the second portion is releasably engaged with the first portion, allowing for easy disengagement and reuse, and featuring mechanical features such as protrusions and recesses for secure engagement and removal, utilizing a tool for torque-based disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional locator pins are used to retain panels during assembly, then the panel is securely held in position, but the pins become difficult to remove and require additional trim components to cover them
Solution Approach 1:
The locator pin is divided into two separate portions: a first portion that remains secured to the panel and a second portion that can be removed from the component. This segmentation allows the pin to provide reliable retention during assembly while enabling easy removal of the second portion after assembly is complete, eliminating the need for additional trim components.
2Manufacturing precision
If conventional locator pins are used, then panel positioning is achieved, but aesthetic appearance is compromised due to visible pins requiring trim coverage
Solution Approach 1:
By separating the locator pin into two portions, the design allows the first portion to maintain precise panel positioning during assembly while the second portion can be completely removed after assembly. This eliminates visible pins and the need for trim components, thereby improving aesthetic appearance without compromising manufacturing precision.
3Stability of the object's composition
If locator pins are designed for secure retention, then panel stability is maintained, but the pins cannot be easily removed or reused
Solution Approach 1:
The two-portion design enables the first portion to provide stable panel retention during assembly while the second portion can be easily disengaged and reused in subsequent assemblies. This segmentation resolves the contradiction between maintaining stability during use and enabling adaptability for reuse after use.
Solution Approach 2:
The second portion of the locator pin is designed to be temporarily discarded (removed) after serving its retention function, and then recovered (reused) in subsequent assemblies. This principle enables the pin system to maintain stability during assembly while providing adaptability for reuse, eliminating waste and reducing costs.

AI summary
A method of assembly includes providing a panel. The method also includes providing a locating member with a first portion and a second portion, and securing the first portion to the panel. The second portion is releasably engaged with the first portion. The method additionally includes providing a component with an orifice for receiving a locating member, and disposing the second portion in the orifice to locate the panel in a desired position relative to the component. The method further includes securing the panel to the component, and disengaging the second portion from the first portion.
