Four-Section Articulated Link Mechanism for Smooth Display Tilt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information apparatuses with slide and tilt mechanisms suffer from a non-smooth transition from a closed to a tilted state and lack the ability to adjust the tilt angle of the display part with respect to the main body, compromising operability.
Innovation Solution
A four-section articulated link mechanism is employed, featuring a mounting plate system with joints and links that allow the display part to slide and tilt smoothly, with adjustable tilt angles facilitated by a tilt angle setting mechanism, enabling seamless transformation between configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a two-stage operation (slide then tilt) is used, then the slide and tilt functions are achieved, but the operation feeling from closed state to tilted state is not smooth
Solution Approach 1:
The patent combines the slide mechanism and tilt mechanism into a single integrated four-bar linkage mechanism. The link mechanism simultaneously achieves both sliding and tilting motions through coordinated movement of its components, eliminating the need for separate two-stage operations and providing smooth continuous motion from closed to tilted state.
Solution Approach 2:
The patent employs a dynamic four-bar linkage mechanism where the connections between the display part and main body are not fixed but can dynamically adjust their positions and angles. This allows the mechanism to adapt its configuration during operation, enabling smooth transition and variable tilt angles rather than rigid fixed-angle tilting.
2Adaptability or versatility
If a fixed tilt angle mechanism is used, then the structure is simple, but the tilt angle of the display part cannot be changed
Solution Approach 1:
The four-bar linkage mechanism is designed with dynamic degrees of freedom that allow the tilt angle to vary during operation. The connections between links permit angular adjustment, enabling the display part to achieve different tilt angles based on the operational requirements rather than being constrained to a single fixed angle.
Solution Approach 2:
The mechanism is divided into multiple independent links and joints that can move relative to each other. This segmentation allows each component to contribute to the overall motion, enabling variable tilt angles through coordinated movement of the segmented links while maintaining structural integrity.

AI summary
A link mechanism which links a main body and a display part of an information apparatus with a display part which can be opened and closed with respect to a main body is made a four-section articulated link mechanism which arranges first and second joints on the main body and arranges third and fourth joints on the display part. The first joint is fixed in position, the second joint is made slidable with respect to the first joint, and the third and fourth joints are positioned at two ends of a slide block which can slide on the display part. Due to this, the four-section articulated link mechanism can make the display part simultaneously slide and tilt with respect to the main body from the closed position.
