Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable electronic devices have a large volume, unsightly periphery during use, and insufficient use comfort due to their design.
Innovation Solution
A foldable electronic device design featuring a pivot module, linkage mechanism, and input module, where the linkage mechanism includes a tooth set, guide set, and linkage set to enable the input module to move close to or away from the pivot module, and be inclined or parallel to the first body, optimizing space utilization and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the input module is fixed in position, then the structure is simple, but the device volume is large and carrying is inconvenient
Solution Approach 1:
The input module is designed to be movable rather than fixed, allowing it to adjust its position and angle relative to the first body. The linkage mechanism enables the input module to pivot and translate, providing dynamic adaptability that resolves the contradiction between compact volume and comfortable operation.
Solution Approach 2:
The device is divided into separate functional modules (first body, second body, input module) connected by pivot modules and linkage mechanisms. This segmentation allows independent movement and adjustment of each module, enabling the input module to be positioned optimally for operation while maintaining compact overall volume when folded.
2Ease of operation
If the input module is movable, then the operation angle is improved, but the structure becomes complex
Solution Approach 1:
The pivot module and linkage mechanism are integrated into a unified structural system where the linkage mechanism is disposed within the first body and connected to the pivot module. This merging reduces the number of separate components and simplifies the overall structure while still achieving the desired input module mobility and angle adjustment.
Solution Approach 2:
The linkage mechanism serves multiple functions simultaneously: it enables the input module to move closer to or away from the pivot module, adjusts the input module's angle relative to the first body, and facilitates the folding/closing action of the second body. This multi-functionality reduces the need for separate mechanisms for each function.
3Volume of moving object
If the second body is closed relative to the first body, then portability is improved, but the display periphery appears unsightly during use
Solution Approach 1:
The input module's position and angle are dynamically adjustable, allowing it to move to different locations on the first body. This enables the input module to be positioned to block or cover the junction area between the first and second bodies when the second body is closed, improving the visual appearance of the display periphery while maintaining compact folded volume.

AI summary
A foldable electronic device includes a first body, a second body, a pivot module, a linkage mechanism, and an input module. The pivot module is connected to the first body and the second body. The second body is pivoted on the first body through the pivot module. The linkage mechanism is disposed in the first body and is connected to the pivot module. The input module is movably disposed on the first body through the linkage mechanism. The linkage mechanism is configured to be driven by the pivot module to cause the input module to move to be close to or away from the pivot module and cause the input module to be inclined or parallel to the first body.
