Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable electronic devices face structural complexity due to the need for additional slide grooves on wing members and the requirement for transmission members to be connected via sliding pins, which complicates the folding mechanism.
Innovation Solution
A foldable electronic device with a central base, arc-shaped sliders, pivot modules, transmission members, and an elastic module that allows for synchronized rotation and linear sliding of panel bodies, enabling a flexible screen to transform between unfolded and folded states while simplifying the structural complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional slide grooves are added on wing members and sliding pins are used to connect transmission members, then the folding mechanism can achieve synchronized rotation and linear sliding, but the structural complexity increases
Solution Approach 1:
The patent combines the sliding groove and sliding pin functions into an integrated arc-shaped slider component that is part of the wing member structure itself, eliminating the need for separate slide grooves on the wing member and separate sliding pins for connecting transmission members. The arc-shaped slider inherently provides both the guidance path and the connection function.
Solution Approach 2:
The arc-shaped slider serves multiple functions simultaneously: it acts as a guide for the transmission member's linear sliding motion, provides the connection between the wing member and transmission member, and enables the synchronized rotation of both panel bodies through its arc-shaped geometry that constrains the relative motion.
2Adaptability or versatility
If a complex hinge structure with multiple rotary structures and sliding grooves is used, then the first and second panel bodies can rotate in opposite directions, but the device complexity increases
Solution Approach 1:
The hinge structure is segmented into independent arc-shaped sliders for each panel body, where each slider operates independently to provide the rotation and linear sliding functions. This segmentation allows each panel body to rotate in opposite directions without requiring a complex integrated rotary structure, as each arc-shaped slider handles its own panel body's motion independently.
