Display Stand With Four-Bar Link Height Tilt Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display device stands fail to simultaneously adjust the height, tilt, and distance of a display device, limiting user convenience and the ability to position the device at elevated heights.
Innovation Solution
A stand incorporating a dual hinge system with a four-bar link mechanism, allowing for simultaneous adjustment of height, tilt, and distance through a hinge connecting unit that moves within a slide housing, enabling two degrees-of-freedom movement when extruded and one degree-of-freedom when inserted, along with a plate spring mechanism for elastic support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sliding assembly is used to adjust height, then height adjustment is enabled, but tilt and distance cannot be adjusted simultaneously
Solution Approach 1:
The stand is divided into multiple independent adjustment mechanisms: a height adjustment mechanism with a sliding assembly, a tilt adjustment mechanism with a four-bar link, and a distance adjustment mechanism. Each mechanism can operate independently, allowing any combination of height, tilt, and distance adjustments to be made simultaneously.
Solution Approach 2:
The patent implements nested adjustment mechanisms where the tilt adjustment mechanism is integrated within the height adjustment structure. The four-bar link mechanism for tilt adjustment is positioned within the vertical column assembly, allowing compact integration while maintaining independent operation of both height and tilt adjustments.
2Ease of operation
If a four bar link is used to adjust tilt, then tilt adjustment is easy, but height adjustment is limited by stand constraints
Solution Approach 1:
The stand structure is segmented into a base unit, a vertical column assembly with height adjustment capability, and a display support unit with tilt adjustment. This segmentation allows the height adjustment mechanism (sliding assembly) and tilt adjustment mechanism (four-bar link) to operate independently without interfering with each other's range of motion.
Solution Approach 2:
The patent adds a vertical dimension to the tilt adjustment mechanism by positioning the four-bar link within the vertically extendable column assembly. This allows the tilt mechanism to operate in conjunction with height adjustment, effectively adding vertical movement capability while maintaining the horizontal tilt adjustment function.
3Ease of manufacture
If the stand structure is simplified, then manufacturing is easier, but multiple adjustment functions cannot be achieved
Solution Approach 1:
The stand is designed as modular segmented components: a base with height adjustment mechanism, a vertical column with sliding assembly, a display support unit with four-bar link tilt mechanism, and adjustable arms for distance control. Each module can be manufactured separately using standard fabrication processes, then assembled through straightforward mechanical connections.
Solution Approach 2:
The patent employs universal joints and standardized connection interfaces that allow the same basic component types to serve multiple functions. For example, the sliding assembly serves both as a height adjustment mechanism and as a structural support element, while the four-bar link mechanism provides both tilt adjustment and structural stability.

AI summary
An improved stand for a display device that allows reliable and multi-faceted adjusting of the display device is provided. The stand includes a base (2), a slide housing (10), a hinge, a fixing unit, and a hinge unit. The slide housing (10) is fixed to the base (2) at an end thereof and extends upward from the base. The hinge connecting unit (30) is guided to move along an extending direction of the slide housing (10). The fixing unit (40) connects an upper end of the hinge connecting unit (30) to a display device (1). The hinge unit is disposed below the hinge connecting unit (30) to allow the hinge connecting unit (30) and the display device (1) to pivot.
