Pivoting Display Head Mechanism for Compact Portrait Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face challenges in mobility due to size constraints, with mobile devices being too small for convenient handling and larger devices requiring extensive installation space, and there is a need for a display that can pivot between landscape and portrait modes with a simple structure while maintaining a compact and aesthetically pleasing design.
Innovation Solution
A display apparatus featuring a base, a stand, a pivotable head with a penetration groove and inner bracket, a shaft with extensions, a guide pin, and a spring mechanism that allows the head to switch between landscape and portrait modes, enabling easy adjustment and maintaining contact between the slider and inner bracket for stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display apparatus is made larger to improve visibility, then the display area increases, but the installation space requirement increases and mobility decreases
Solution Approach 1:
The display head is made pivotable between landscape and portrait modes through a shaft mechanism with slider and spring, allowing the same display area to be adapted to different viewing needs without requiring different installation spaces. The pivotable structure enables dynamic reconfiguration of the display orientation while maintaining a compact footprint.
2Area of stationary object
If the display apparatus is made smaller to improve portability, then the installation space requirement decreases, but the display area decreases
Solution Approach 1:
The pivotable head mechanism allows a compact display apparatus to provide both landscape and portrait viewing modes, maximizing the utility of the available display area within a small installation footprint. The same physical display can be oriented differently to suit various viewing distances and angles.
3Adaptability or versatility
If a complex pivot mechanism is used to enable landscape and portrait mode switching, then the mode switching capability improves, but the device complexity increases
Solution Approach 1:
The pivot mechanism is segmented into distinct functional components: a shaft with first and second extensions, a slider that moves along the shaft, and a spring that provides restoring force. This segmentation allows each component to perform its specific function independently, simplifying the overall design while achieving the desired landscape-portrait switching capability.
Solution Approach 2:
The slider is disposed on the outer circumference of the second extension of the shaft, with the spring nested around the second extension. The inner bracket with the slit is positioned to interact with the slider. This nested arrangement allows multiple components to occupy compact space while maintaining their functional relationships, reducing overall device complexity.
4Adaptability or versatility
If the head is made pivotable between landscape and portrait modes, then the versatility improves, but the structural complexity increases
Solution Approach 1:
The pivotable head achieves versatile orientation switching through a dynamic mechanism where the slider moves along the shaft's second extension. The spring provides automatic restoring force to maintain contact between the slider and the inner bracket, enabling smooth transitions between landscape and portrait modes without complex control systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for a compact, aesthetically designed display that can pivot between modes without requiring significant horizontal or vertical movement, ensuring stable operation and intuitive use, while also allowing the device to be used as a standing mirror or light due to its tilting capabilities.
Implementation Method 1
a spring disposed on an outer circumference of the second extension and configured to pressurize the slider to maintain contact between the slider and the inner bracket
