Flip Touch Screen Support Linkage for Stable Tilt Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic apparatuses with flip touch screens face challenges in maintaining the upper cover in a stable angular position without damaging pivot units and providing sufficient support for the liquid crystal screen, especially in slider designs, where the support structure is insufficient and prone to shaking.
Innovation Solution
An auxiliary support device that includes a main body with a cavity and an upper cover with an elongated recess, featuring a slide rail, link member, and elastic members, allowing for adjustable angle and force support to reinforce the upper cover when turned upward, utilizing a pivot unit and support shaft for stability and a locking mechanism to secure the position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upper cover is opened to a tilted position for user interaction, then the touch panel is accessible, but the pivot units are likely to damage due to great effort moment
Solution Approach 1:
The patent introduces a support structure as an intermediary component between the upper cover and the pivot units. This support structure includes a support arm and a support spring that work together to bear part of the load when the upper cover is in the tilted position, thereby reducing the effort moment transmitted to the pivot units and preventing their damage.
2Stability of the object's composition
If the upper cover is supported by conventional support structure, then the upper cover can be held in position, but the support force is insufficient causing screen shaking
Solution Approach 1:
The patent employs a support spring as a cushioning element that is pre-installed in the support structure. When the upper cover is opened to a tilted position, the support spring is compressed and stores elastic potential energy, providing a cushioning force that stabilizes the upper cover and prevents screen shaking. This beforehand cushioning ensures reliable screen stability during operation.
3Adaptability or versatility
If a slider mechanism is used for the upper cover, then the upper cover can be slid and rotated, but the mechanism is complicated with considerable thickness
Solution Approach 1:
The patent divides the movement function into two independent stages: a sliding stage and a rotating stage. The slide mechanism and the rotation mechanism are segmented as separate functional modules. This segmentation allows each mechanism to be optimized independently, reducing the overall complexity and thickness while maintaining the versatility of the upper cover movement capability.

AI summary
An auxiliary support device for flip touch screen includes a main body and an upper cover having a touch panel. The main body is preformed with a cavity for assembling with a base seat. The upper cover is preformed with an elongated recess corresponding to the cavity. A slide rail is assembled in the elongated recess. One end of a link member is movably pivotally connected with an outer end of the base seat. A bottom end of a slide member is movably pivotally connected with an inner end of the base seat. The slide member is assembled in the slide rail. The other end of the link member is slidably connected with of a surface of the slide member. When the upper cover is turned upward, the link member is turned upward with the slide member to obliquely support the upper cover.
