Connector Alignment Through-Hole With Visual Recognition Mark
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector devices face challenges in aligning connectors without damaging the reinforcing plate, as the stress concentration at the end portions during removal can lead to damage, and increasing the plate's size to prevent damage results in an oversized connector device.
Innovation Solution
A connector device with a substrate featuring a through hole closed in a plane perpendicular to the up-down direction, equipped with a visual recognition mark on the mounting surface, allowing for image-recognizable alignment using a single image sensor, and a method for mating connectors that simplifies the alignment process while maintaining the substrate's strength without size increase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the width size of the reinforcing plate is increased to prevent damage during removal, then the strength and reliability of the connector device is improved, but the overall size of the connector device increases
Solution Approach 1:
The reinforcing plate is divided into a main body portion and finger-hookable end portions. This segmentation allows the end portions to be optimized for finger hooking (smaller width) while the main body maintains sufficient strength, resolving the contradiction between strength and size.
Solution Approach 2:
Different regions of the reinforcing plate are given different properties: the end portions are designed with smaller width for easy finger hooking, while the main body portion maintains larger dimensions for structural strength. This local differentiation resolves the contradiction by optimizing each region for its specific function.
2Ease of operation
If dent portions are provided at end portions to enable easy alignment, then the ease of operation is improved, but the stress concentration at root portions increases leading to potential damage
Solution Approach 1:
The reinforcing plate is segmented into a main body and separate end portions that can be hooked by fingers. This segmentation allows the end portions to provide alignment functionality while the main body maintains structural integrity, avoiding stress concentration issues.
Solution Approach 2:
Instead of providing dent portions that create stress concentration, the invention inverts the approach by creating a through-hole that distributes stress and provides alignment guidance without compromising structural strength at critical regions.
3Ease of operation
If a through-hole is provided in the substrate for visual recognition, then the ease of operation is improved, but the structural strength of the substrate may be reduced
Solution Approach 1:
Instead of adding external alignment features that may compromise structure, the invention uses a through-hole that passes through the substrate, allowing visual recognition from both sides and providing alignment guidance without adding external protrusions that could create stress concentration points.
Solution Approach 2:
The visual recognition mark is created as a through-hole that can be seen from both sides of the substrate, effectively creating multiple views of the same alignment feature without adding additional structural elements that would compromise strength.

AI summary
A connector device is provided with a substrate and a connector joined to the substrate. The substrate is provided with a through hole which pierces the substrate. The connector has a mounting surface, and the mounting surface is directed to the substrate. The mounting surface is formed with a visual recognition mark. The visual recognition mark is visually recognizable through the through hole.
