Notebook Hinge Segmented Connectors Prevent LCD Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinges for notebook computers fail to effectively prevent the liquid crystal display (LCD) from bumping the host when closing, especially with large and heavy LCDs, leading to potential damage.
Innovation Solution
A hinge design featuring a first connector with an L-shaped configuration, a second connector with a sleeve and plate, and a third connector with a pivot and plate, allowing for easy assembly and enabling the LCD to be pivoted and retained at any angle, using a simple structure with few parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional hinge with block and sector-shaped positioning plate is used, then the LCD can be connected to the host, but the hinge cannot effectively halt the LCD before bumping the host when the LCD is large and heavy
Solution Approach 1:
The hinge is divided into multiple connectors (first connector with L-shaped configuration, second connector with sleeve and plate, third connector with pivot and plate) that work together to provide progressive stopping stages, allowing the LCD to be halted effectively before bumping the host
Solution Approach 2:
The L-shaped first connector acts as an intermediary structure between the host and the LCD, providing a mechanical advantage through its perpendicular arms to amplify the stopping force and prevent LCD damage
2Reliability
If a complex multi-step positioning mechanism is used, then the LCD can be halted effectively, but the assembly becomes difficult and time-consuming
Solution Approach 1:
The hinge is segmented into three main connectors with clear functional divisions, allowing each component to be manufactured and assembled independently, simplifying the overall assembly process while maintaining effective stopping capability
Solution Approach 2:
Multiple functional elements (positioning, pivoting, stopping) are merged into a compact arrangement of three connectors that work together seamlessly, reducing the number of separate components and simplifying assembly
3Ease of manufacture
If a simple hinge structure with few parts is used, then the assembly is easy, but the hinge cannot effectively prevent the LCD from bumping the host
Solution Approach 1:
The hinge incorporates dynamic elements including the pivoting third connector and the L-shaped first connector that can rotate and adjust positions, allowing a simple structure to provide effective stopping through motion rather than complex mechanical constraints
Solution Approach 2:
The L-shaped first connector introduces a dimensional change with its perpendicular arms, creating a mechanical lever arm that amplifies the stopping force in a different dimension, allowing a simple structure to achieve effective protection

AI summary
A hinge includes a first connector, a second connector and a third connector. The first connector includes a first section and a second section extending from the first section at a right angle. The second connector includes a sleeve and a plate secured to the second section of the first connector. The third connector includes a pivot inserted in the sleeve and a plate extending from the pivot.
