Connector With Partition Walls For Display Device Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face challenges in achieving reduced thickness and increased size with higher definition, particularly in the electrical connections between the display panel, cable, and printed circuit board, where connectors like ZIF and BTB connectors are limited in their ability to securely connect without misalignment and breakage.
Innovation Solution
A connector design featuring a header unit with a base and partition walls of varying widths, including protrusions, that securely connects to a socket with corresponding cavities and terminals, preventing misalignment and enhancing the fastening force through a T or H shape configuration and protrusions, ensuring stable electrical connections between the cable and printed circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional ZIF or BTB connectors are used with protruding contact pins, then electrical connection is achieved, but misalignment and breakage occur reducing connection reliability
Solution Approach 1:
The connector is divided into a header unit and a socket unit with distinct functional regions. The header unit includes connection terminals arranged in specific patterns on a base, while the socket unit has corresponding receiving structures. This segmentation allows independent optimization of each unit and simplifies the overall connection mechanism.
Solution Approach 2:
The header unit incorporates partition walls with asymmetric width variations (first width, second width larger than first width, third width equal to or different from second width) that create a T-shape or H-shape configuration. This asymmetric design provides built-in alignment features that prevent misalignment during connection while maintaining structural simplicity.
2Reliability
If connection terminals protrude to the outside for electrical connection, then electrical connectivity is established, but terminal breakage occurs due to exposure and stress
Solution Approach 1:
The connection terminals are nested within the header unit structure rather than protruding externally. The terminals are positioned on the base and partition walls, with the partition walls providing protective enclosure. This nesting approach protects terminals from external stress and breakage while maintaining electrical connectivity through the socket interface.
Solution Approach 2:
The connection terminals are arranged in multiple dimensions on the base and partition walls, including vertical positioning on the first surface of partition walls. This multi-dimensional arrangement distributes mechanical stress across different spatial locations, reducing the likelihood of terminal breakage while ensuring reliable electrical contact.
3Manufacturing precision
If partition walls have uniform width for simple manufacturing, then manufacturing is easier, but alignment precision and fastening force are insufficient
Solution Approach 1:
The partition walls incorporate localized width variations rather than uniform width throughout. Specifically, the first partition wall has a first width at one section and a second width (larger than first width) at another section, creating local structural features. This local quality approach provides precise alignment features at critical locations while keeping the overall manufacturing process relatively simple.
4Reliability
If connector structure is simplified for ease of manufacture, then production is easier, but fastening force and connection stability are reduced
Solution Approach 1:
The header unit integrates multiple functions into a single structure: the base provides mounting and terminal support, while the partition walls simultaneously provide structural reinforcement, alignment features, and fastening surfaces. The T-shape or H-shape configuration merges these functions efficiently, achieving high connection stability without excessive structural complexity.
Solution Approach 2:
The partition walls are configured to form T-shape or H-shape structures with specific geometric curves and angles. These shaped configurations optimize the distribution of fastening force across the connection interface, enhancing connection stability while maintaining manufacturability through standard forming processes.
