Door Striker Pin Positioning Tool for Consistent Latch Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing a striker pin in vehicles often result in improper alignment with the latch, leading to insecure door closure and varying closing forces across different vehicles, which can be time-consuming and perceived as low quality.
Innovation Solution
A tool with a latch engagement section and a pin positioning section that aligns the striker pin slot with the installation location, allowing precise alignment and secure fixation of the striker pin, ensuring consistent closing forces across vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional trial and error method is used to install striker pin, then installer can attempt alignment, but alignment precision is poor and door closure consistency deteriorates
Solution Approach 1:
The patent introduces a positioning tool as an intermediary device between the installer and the striker pin installation process. This tool includes a positioning section with a striker pin slot that guides the striker pin into precise alignment with the latch, and an abutment section that rests against the vehicle frame to establish correct positioning. The intermediary tool eliminates the need for trial and error by providing mechanical guidance for accurate alignment.
Solution Approach 2:
The positioning tool performs preliminary alignment action before the actual striker pin installation. The striker pin slot is pre-positioned to align with the target location on the vehicle frame, and the abutment section is designed to contact the frame at the correct position beforehand. This preliminary positioning ensures that when the striker pin is installed through the slot, it is already in the correct alignment, preventing the need for subsequent adjustments.
2Productivity
If trial and error installation method is used, then installer can attempt positioning, but installation time increases
Solution Approach 1:
The positioning tool serves as a mechanical intermediary that directly guides the striker pin to the correct position, eliminating the time-consuming trial and error process. The striker pin slot provides a predefined path that leads the pin to the exact installation location, while the abutment section ensures correct positioning relative to the vehicle frame, enabling rapid and accurate installation in a single attempt.
Solution Approach 2:
The tool performs preliminary positioning of the striker pin before installation by using the pre-configured striker pin slot and abutment section. This preliminary action establishes the correct alignment and position in advance, allowing the installer to simply insert and secure the pin without repeated adjustments, thereby significantly reducing installation time.
3Ease of manufacture
If striker pin alignment is improper, then installation may be completed, but door closure security deteriorates
Solution Approach 1:
The positioning tool acts as a mechanical intermediary that enforces correct alignment during installation. The striker pin slot is precisely positioned to guide the pin into proper alignment with the latch, and the abutment section contacts the vehicle frame to maintain correct positioning. This intermediary guidance system ensures that even an inexperienced installer can achieve proper alignment, maintaining both installation simplicity and door closure security.
Solution Approach 2:
The tool performs preliminary alignment of the striker pin with the latch and vehicle frame before the actual installation occurs. By pre-positioning the striker pin through the correctly oriented slot and abutment section, the system ensures proper alignment is achieved in advance, allowing for simple installation while guaranteeing door closure security through predetermined geometric relationships.

AI summary
A tool for installing a door striker pin includes: a latch engagement section having a first surface, a striker pin extending from the first surface, and an abutment surface that extends generally orthogonal to the first surface; and a pin positioning section coupled to the latch engagement section and including a positioning surface with a striker pin slot formed therethrough that extends in parallel with the striker pin. The striker pin slot is positioned in the positioning surface such that the striker pin slot is aligned with a striker pin installation location when the striker pin of the latch engagement section is engaged with a latch of a door and the abutment surface rests against a frame to which the door is pivotably coupled.
