Dual Display Portable Computer Hinge Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable computers with integrated displays face limitations in displaying large screens for tasks like movies or CAD/Spread Sheet work, requiring separate monitors and lacking flexibility in language input, as they have fixed keyboard languages and limited screen configuration options.
Innovation Solution
A dual display portable computer design featuring a hinge mechanism that allows two display modules to be folded and unfolded at various angles, with one module serving as an input device, enabling flexible screen configurations and language input without external keyboards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a separate monitor is connected to achieve large screen display, then the display area is improved, but the portability and ease of operation deteriorates
Solution Approach 1:
The patent combines two display modules into a single portable computer system, where the second display module can be folded onto the body section. This merging approach provides large screen area when needed while maintaining portability when the displays are folded together, eliminating the need for external monitors.
Solution Approach 2:
The hinge mechanism enables dynamic configuration of the display modules, allowing them to be unfolded for large screen display or folded for compact portability. This dynamic adjustment resolves the contradiction between display area and portability by providing both states within a single device.
2Ease of manufacture
If a fixed language keyboard is used, then the manufacturing simplicity is improved, but the adaptability deteriorates
Solution Approach 1:
The second display module serves multiple functions: it can display additional window screens, display keyboard images for different languages, and function as an input device through touch input. This multi-functionality provides language adaptability without requiring separate physical keyboards for each language.
Solution Approach 2:
Instead of creating separate physical keyboards for different languages, the patent uses virtual keyboard images displayed on the second display module. This copying approach allows multiple language configurations to be provided through software rather than hardware, maintaining manufacturing simplicity while improving adaptability.
3Adaptability or versatility
If multiple display modules are added to increase display area, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The portable computer is segmented into distinct functional modules: a body section with a first display module and a second display module connected through a hinge mechanism. This segmentation allows each module to be optimized independently while providing versatile display configurations when combined.

AI summary
A dual display type portable computer can include a first unit having a first display module and a second unit rotatably coupled to the first unit having a second display module. At least one hinge unit can couple the first unit and the second unit with each other. The hinge unit can be coupled to corresponding positions of the first unit and the second unit to enable the first display module and the second display module to overlap each other or to be unfolded until they are placed in an equal plane. Preferably, at least one of the first display module and the second display module has a touch screen function. Preferably, the touch screen function can selectively change a language of a keyboard image. The first display module and the second display module can display different images or divided portions of one integrated image.
