Pivoting Display Head Mechanism for Compact Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face challenges in mobility due to their size, with mobile devices being too small for convenient handling and larger devices requiring wide installation spaces, and there is a need for a compact display that can easily switch between landscape and portrait modes.
Innovation Solution
A display apparatus with a pivotable head that utilizes a simple structure featuring guide grooves and pins, allowing the head to switch between landscape and portrait modes while maintaining stability and allowing intuitive pivoting without adjusting the device's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display apparatus is made larger to improve viewing experience, then the display size increases, but the installation space requirement increases and mobility decreases
Solution Approach 1:
The head is designed to be pivotable between landscape and portrait modes using guide grooves and guide pins, allowing the display apparatus to dynamically adapt its orientation. This dynamic capability enables a compact desktop display to function in multiple orientations, effectively providing the versatility of larger devices while maintaining a compact form factor for ease of placement and mobility.
2Ease of operation
If the display apparatus is made compact to improve mobility, then the installation space requirement decreases, but the viewing experience and functionality are limited
Solution Approach 1:
The pivotable head mechanism with guide grooves and guide pins enables the compact display to dynamically switch between landscape and portrait orientations, providing orientation flexibility typically associated with larger, more versatile devices. This dynamic adaptation allows a single compact unit to serve multiple functional needs.
3Adaptability or versatility
If a pivotable head mechanism is added to enable mode switching, then the orientation flexibility improves, but the device complexity increases
Solution Approach 1:
The pivotable head mechanism is segmented into distinct components: guide grooves formed in the base, guide pins attached to the head, and a connecting bar. This segmentation allows each component to perform a specific function while maintaining overall simplicity. The guide grooves and guide pins work together as a straightforward mechanical guidance system, avoiding complex actuation mechanisms.
Solution Approach 2:
The guide grooves and guide pins create a self-guiding mechanism where the head automatically follows the predetermined curved trajectory during pivoting. The mechanical design itself provides the guidance and constraint, eliminating the need for additional control systems, sensors, or actuators to manage the pivoting motion.
4Ease of operation
If the head is made pivotable to enable mode switching, then the user convenience improves, but the structural stability may be compromised
Solution Approach 1:
The pivotable head mechanism provides controlled dynamic movement between landscape and portrait modes while maintaining structural stability in each position. The guide grooves and guide pins ensure that the head follows a predetermined curved trajectory, providing stable positioning in both orientations without compromising overall structural integrity.
