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 large devices requiring extensive installation space, and there is a need for a display that can easily switch between landscape and portrait modes with a simple structure.
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 pivot between landscape and portrait modes while maintaining stability and allowing for tilt and swivel motions, enabling intuitive adjustment without horizontal or vertical movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display apparatus is made larger to improve handling convenience, then the mobility is reduced due to requiring extensive installation space
Solution Approach 1:
The display head is made pivotable between landscape and portrait modes through a shaft mechanism with penetration grooves and guide pins, allowing the display to dynamically adjust its orientation and effective size according to usage needs, thus providing large-screen convenience when needed while maintaining compact footprint for mobility
2Area of stationary object
If the display apparatus is made smaller to improve mobility, then the handling convenience is reduced
Solution Approach 1:
The pivotable head mechanism allows the display to transition between landscape and portrait modes, effectively providing a larger display area when needed while maintaining a compact physical footprint for mobility, thus resolving the contradiction between size and convenience
3Adaptability or versatility
If a complex structure is used to enable pivotable head between landscape and portrait modes, then the device complexity increases
Solution Approach 1:
The pivot mechanism is segmented into discrete components: a shaft with first and second extensions, penetration grooves in the head, guide pins in the inner bracket, and a slider. These segmented parts work together through simple geometric constraints (grooves guiding pins, slider moving along shaft) to enable mode switching without requiring a complex integrated mechanism
Solution Approach 2:
The slider acts as an intermediary element between the shaft and the head, translating the rotational motion into the pivotable movement of the display head. The spring provides intermediate elastic force to maintain contact between components during the pivoting motion, simplifying the overall mechanism
