Display Stand Linkage for Height, Tilt, and Distance Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display device stands cannot simultaneously adjust the height, tilt, and distance of a display device, limiting user convenience and the ability to position the device at a substantially elevated height.
Innovation Solution
A stand with a dual hinge system and four bar link mechanism that allows for simultaneous adjustment of the display device's height, tilt, and distance through a combination of sliding and pivoting movements, utilizing a plate spring for elastic support and retaining ridges for precise positioning.
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 adjustments cannot be made simultaneously
Solution Approach 1:
The stand is divided into multiple independent functional modules: a sliding assembly for height adjustment, a four bar link mechanism for tilt adjustment, and a hinge connecting unit for distance adjustment. Each module operates independently to control a specific degree of freedom, allowing all three parameters (height, tilt, distance) to be adjusted simultaneously without interfering with each other.
Solution Approach 2:
The four bar link mechanism is nested within the sliding assembly structure, with the hinge connecting unit integrated into the four bar link system. This nested configuration allows multiple adjustment mechanisms to occupy the same spatial envelope while maintaining independent functionality, enabling simultaneous operation of height, tilt, and distance adjustments.
2Ease of operation
If a four bar link is used to adjust tilt, then tilt adjustment is enabled, but height adjustment is limited
Solution Approach 1:
The stand structure separates the height adjustment function (handled by the sliding assembly) from the tilt adjustment function (handled by the four bar link mechanism). This segmentation allows each mechanism to be optimized for its specific function without compromising the other, enabling full height adjustment range while maintaining smooth tilt adjustment capability.
3Ease of manufacture
If the stand structure is simplified, then manufacturing is easier, but multiple ranges of movement for height, tilt, and distance cannot be achieved
Solution Approach 1:
The hinge connecting unit serves multiple functions: it connects the four bar link mechanism to the display device, enables distance adjustment through pivoting motion, and provides a mounting point for the plate spring. This multi-functional design reduces the total number of components needed while maintaining the capability for height, tilt, and distance adjustments across multiple ranges.
Solution Approach 2:
The plate spring provides variable elastic force that changes with compression distance, allowing the stand to accommodate different weight loads and adjustment positions. This parameter change capability enables the stand to maintain stability across multiple ranges of movement without requiring complex active control systems.

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, a slide housing, a hinge, a fixing unit, and a hinge unit. The slide housing is fixed to the base at an end thereof and extends upward from the base. The hinge connecting unit is guided to move along an extending direction of the slide housing. The fixing unit connects an upper end of the hinge connecting unit to a display device. The hinge unit is disposed below the hinge connecting unit to allow the hinge connecting unit and the display device to pivot.
