Pivoting Mechanism for Thin Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with large, heavy displays are prone to scraping the supporting casing during rotation due to inadequate friction mechanisms, leading to design challenges for a thin-typed appearance and protection.
Innovation Solution
A pivoting mechanism comprising a first and second driving component, a pivot shaft, and a rotary unit with a slot structure, where the rotary unit contacts the body to provide stable support and prevent collision during rotation, allowing for multiple modes of operation while maintaining a slim design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display is made large-scaled for comfortable entertainment enjoyment, then the viewing comfort is improved, but the volume and weight of the display increase, making it easy to scrape the casing of the supporter during rotation
Solution Approach 1:
A protective layer is introduced as an intermediary between the display and the supporter casing. This protective layer absorbs the friction and prevents direct contact between the heavy display and the casing, thereby preventing scraping while allowing the display to maintain its large size for comfortable viewing
2Stability of the object's composition
If the pivot mechanism utilizes friction to generate force for supporting the display, then the pivot angle can be fixed, but the display is heavy and the mechanism cannot prevent scraping of the supporter
Solution Approach 1:
The protective layer serves as a mediator between the friction-based pivot mechanism and the supporter casing. It allows the friction mechanism to maintain pivot angle stability while preventing the heavy display from directly scraping the supporter during rotation
Solution Approach 2:
The protective layer is pre-installed on the supporter casing to provide cushioning before any scraping can occur. This preventive measure ensures that even when the heavy display rotates under friction-based support, the casing is protected from damage
3Volume of moving object
If the display has huge volume, then the entertainment functionality is improved, but the weight increases and the device cannot achieve thin-typed appearance
Solution Approach 1:
The pivot mechanism is segmented into multiple functional components: a protective layer, a friction-based pivot joint, and a support structure. This segmentation allows the mechanism to be optimized for each function independently, enabling the display to maintain large volume for entertainment while the segmented mechanism keeps the overall device thickness minimal for a thin-typed appearance
