Display Dock Connector Alignment to Prevent Pin Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in securely and easily coupling connectors, which can lead to damage of pins during coupling and may not provide a stable electrical connection using a minimal number of pins.
Innovation Solution
A display device design that includes a head with a display panel, a stand to support the head, and a docking mechanism using first and second connectors. The first connector has a first pin extending in one direction, and the second connector has a second pin that defines a pin hole for the first pin, allowing for secure and easy alignment and coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are coupled using a conventional pin insertion method, then electrical connection is established, but pins may be damaged during coupling
Solution Approach 1:
A guide structure acts as an intermediary between the first pin and second pin hole, providing alignment guidance during the coupling process. The guide structure includes a guide hole that receives the first pin and guides it into the second pin hole, preventing misalignment and damage during insertion.
Solution Approach 2:
The guide structure is pre-positioned on the second connector before coupling occurs. The guide hole is formed in advance to receive and guide the first pin, ensuring proper alignment is established before the actual electrical connection is made, thereby preventing pin damage during the coupling process.
2Reliability
If multiple pins are used to ensure stable electrical connection, then connection reliability improves, but connector complexity increases
Solution Approach 1:
The connector coupling function is segmented into two independent parts: mechanical alignment provided by the guide structure and electrical connection provided by the pins. This segmentation allows the guide structure to handle alignment tasks, enabling the use of fewer pins for electrical connection while maintaining connection reliability and reducing overall connector complexity.
3Reliability
If connectors are designed for secure coupling, then connection stability improves, but ease of operation deteriorates
Solution Approach 1:
The guide structure serves as a mediator that facilitates easy coupling by providing automatic alignment guidance. The guide hole and guide protrusion work together to automatically align the first and second connectors during insertion, making the coupling process easier while ensuring stable connection through the guide structure's constraint function.
