Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pivot mechanisms in laptop computers are prone to instability and mechanical damage due to external forces, leading to unsatisfactory screen turning functionality and potential malfunction.
Innovation Solution
A pivot mechanism with a base featuring perpendicular first and second connecting members, a pivot structure, and a holding portion with reinforcing ribs, which distributes stress and enhances joining strength between the screen and the laptop body, allowing for stable and smooth turning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base is mounted in the operation direction of the host, then the pivot mechanism can be compact, but the base sways when the screen receives external force, leading to unstable turning
Solution Approach 1:
The base transitions from a linear mounting arrangement (in the operation direction only) to a two-dimensional L-shaped configuration, where the first connecting member extends in the operation direction and the second connecting member extends perpendicular to it, providing stability in multiple directions simultaneously
Solution Approach 2:
The base is divided into two perpendicular connecting members (first and second connecting members) that are fixedly connected to different portions of the host, distributing the structural support function across separate components mounted at right angles to each other
2Strength
If the base is mounted in the operation direction of the host, then the structure is simple, but the base is susceptible to loosening and damage due to excessive external force
Solution Approach 1:
The base structure extends into a second dimension by adding the second connecting member perpendicular to the first, creating an L-shaped configuration that distributes external forces across two orthogonal mounting directions, thereby increasing strength without proportionally increasing complexity
Solution Approach 2:
The first and second connecting members are fixedly connected to the host in advance, establishing a pre-reinforced base structure that is prepared to resist external forces before they are applied, preventing loosening and damage
3Strength
If the pivot structure is disposed on the first connecting member, then the joining strength is enhanced, but the device complexity increases
Solution Approach 1:
The pivot structure is integrated with the first connecting member by being disposed on it, merging the pivoting function with the existing connecting structure rather than adding a completely separate mechanism, thereby enhancing functionality while controlling complexity

AI summary
The present invention discloses a pivot mechanism and an electronic device applying the same. The electronic device includes a first body and a second body that are individually independent. The pivot mechanism is configured to turn the second body relative to the first body so that the second body may be in an open position or a closed position. The pivot mechanism includes a base and a pivot structure. The base includes a first connecting member and a second connecting member, which are fixedly connected on a top portion and a peripheral portion of the first body, respectively. Extension directions of the first second connecting members are perpendicular to each other. The pivot structure is disposed on the first connecting member, and is fixedly connected to the second body. Accordingly, stable joining of the first second bodies is ensured, and turning stability and smoothness are at the same time satisfied.
