Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-screen portable electronic devices are inadequate for multi-tasking scenarios, as they fail to provide efficient visibility and usability for simultaneous tasks.
Innovation Solution
A portable electronic device featuring a linkage mechanism that allows the first display to pivot relative to the base and the second display to tilt on the first display, improving visibility and usage efficiency through a single-step operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-screen portable electronic device is used, then the device structure is simple, but the multi-tasking capability and visibility are insufficient
Solution Approach 1:
The second display is nested within the portable electronic device, positioned between the base and the first display. When the device is closed, the second display is accommodated within the device body; when opened, it can be tilted out to provide additional viewing area for multi-tasking operations.
Solution Approach 2:
The second display is designed with dynamic positioning capability through the linkage mechanism, allowing it to transition between a retracted position (when device is closed) and an extended/tilted position (when device is opened). This dynamic adjustment enables the display to adapt to different usage scenarios without permanently increasing device footprint.
2Adaptability or versatility
If the second display is added to the portable electronic device, then the multi-tasking capability is improved, but the device complexity increases
Solution Approach 1:
The linkage mechanism integrates multiple functions: it supports the second display, enables its tilting motion, and coordinates with the first display's opening/closing action. By merging these functions into a single mechanical system, the patent reduces the number of separate components needed and simplifies the overall structure despite adding dual-screen capability.
Solution Approach 2:
The linkage mechanism serves multiple purposes: it acts as a support structure for the second display, provides the tilting motion mechanism, and coordinates with the hinge mechanism for the first display. This multi-functional design reduces the need for additional separate mechanisms, thereby limiting the increase in device complexity.
3Illumination intensity
If the second display is positioned between the base and the first display, then the visibility is improved, but the space requirement increases
Solution Approach 1:
Instead of expanding the second display horizontally or increasing device thickness, the patent utilizes the vertical dimension by positioning the second display between the base and the first display. The linkage mechanism enables the second display to tilt upward, creating an additional viewing plane that improves visibility without significantly increasing the device's horizontal footprint.
Solution Approach 2:
The second display is nested within the device structure when closed, utilizing the vertical space between the base and the first display. This nesting approach allows the second display to be accommodated within the device's existing volume, minimizing the increase in overall device size while still providing dual-screen functionality when needed.
4Productivity
If the linkage mechanism is used to tilt the second display, then the usage efficiency is improved, but the device complexity increases
Solution Approach 1:
The linkage mechanism merges the support function and the tilting function into a single integrated structure. By combining these functions, the patent avoids adding separate support brackets and tilting mechanisms, thereby limiting the increase in device complexity while still achieving improved usage efficiency through adjustable display positioning.
Applied Scientific Principles

Function Achieved in This Case
Enhances dual-screen functionality, providing improved visibility and ergonomic operation for multi-tasking situations by allowing the second display to tilt on the first display, thus enhancing user experience and efficiency.
Implementation Method 1
When the first display is opened relative to the base, the at least one first link rotates to drive the second display to move up relative to the base
Implementation Method 2
Two ends of the first link are pivotally connected to the first display and the second display respectively
Implementation Method 3
The first display is pivotally connected to the base, and the first display is movable to be opened or closed relative to the base

AI summary
A portable electronic device includes a base, a first display pivotally connected to the base, a second display, and a linkage mechanism. The first display is movable to be opened or closed relative to the base. The second display is located between the base and the first display. The linkage mechanism includes at least one first link. Two ends of the first link are pivotally connected to the first display and the second display, respectively. When the first display is opened relative to the base, the at least one first link rotates to drive the second display to move up relative to the base. When the first display is closed relative to the base, the at least one first link rotates in an opposite direction to drive the second display to move down to be accommodated between the first display and the base.
