Multi-Pivot Support Structure for Portable Electronic Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-screen notebook computers face challenges in providing sufficient mechanical support for a movable screen, leading to difficulties in operation and potential stress on pivoting components due to uneven operating angles and inadequate load distribution.
Innovation Solution
A portable electronic device with a multi-pivot support structure composed of a sliding linkage rod and a multi-unit body, where the support member is movably disposed on one body and pivotally connected to another, effectively distributing torsional loads across the pivots, allowing for improved support and rotation of multiple screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed screen coplanar with the host is used, then the structure is simple, but it is difficult to perform actions on the screen due to fixed operating angles
Solution Approach 1:
The patent transforms the fixed screen into a movable screen by introducing pivot connections between the first body, second body, and third body. The support member enables dynamic adjustment of the second body's position and angle, allowing the screen to move from a fixed coplanar position to various inclined positions, thereby resolving the contradiction between operational flexibility and structural simplicity.
2Ease of operation
If the fixed screen is changed to a movable screen, then operating flexibility is improved, but mechanical support and pivot load become insufficient
Solution Approach 1:
The support member acts as an intermediary mechanical element between the first body and the second body. It provides additional pivot connections that distribute the mechanical load and enhance the structural support for the movable second body, preventing the pivot points from bearing excessive stress while maintaining screen mobility.
Solution Approach 2:
The patent divides the support structure into multiple segmented components: the first body, second body, and third body, each connected through pivot joints. The support member further segments the load-bearing path by introducing additional pivot points, distributing the mechanical stress across multiple connection points rather than concentrating it at single pivot locations.
3Device complexity
If the second body and third body are pivotally connected without support member, then the structure is simple, but the pivoting axles bear excessive load reducing lifespan
Solution Approach 1:
The support member serves as a mediator that introduces additional pivot connections to distribute the load. By adding this intermediary structural element, the patent reduces the burden on individual pivoting axles without significantly complicating the overall structure, thereby extending pivot lifespan while maintaining operational simplicity.

AI summary
A portable electronic device includes a first body, a second body, a third body, and a support member. The second body is pivotally connected between the first body and the third body. The support member is movably disposed at the first body, and the support member is pivotally connected to one of the second body and the third body. In a folded state, the second body is folded and covered between the first body and the third body. In an unfolded state, the second body and the third body are respectively inclined relative to the first body and the second body, and the second body is suspended over the first body.
