Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display stands for multiple computer monitors are often cumbersome, aesthetically unpleasing, and inefficient, with difficult adjustments due to inconsistent counterbalancing and redundant mechanisms, making it hard to align displays smoothly and precisely.
Innovation Solution
A display stand with two legs linked by a horizontally adjustable support bar, featuring synchronized carriage assemblies with rack-and-pinion mechanisms and rotatable handles, allowing vertical, horizontal, and pivot adjustments, along with a slip clutch to prevent over-torque, ensuring smooth and precise alignment of multiple displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent stands or arms are used to support multiple displays, then each display can be positioned independently, but the device complexity increases and the aesthetic appearance deteriorates
Solution Approach 1:
The patent combines multiple display support functions into a single integrated stand structure with a common base and shared support column. Multiple carriage assemblies are mounted on this single structure, allowing multiple displays to be supported by one unified mechanism rather than requiring separate independent stands, thereby reducing overall device complexity while maintaining independent positioning capability through individual carriage adjustments.
Solution Approach 2:
The single stand structure serves multiple functions by supporting multiple displays simultaneously. The common base and support column provide universal support for multiple carriage assemblies, each capable of holding a display. This multi-functional design eliminates the need for multiple separate stands while maintaining the ability to independently position each display through its own carriage mechanism.
2Adaptability or versatility
If traditional adjustment mechanisms are used, then the stand can support multiple displays, but the ease of operation deteriorates due to inconsistent counterbalancing and difficult adjustments
Solution Approach 1:
The patent incorporates counterbalancing mechanisms within each carriage assembly that use springs or elastic elements to offset the weight of the displays. This counterbalancing provides consistent assistance throughout the adjustment range, making it easier for users to move displays vertically and horizontally without experiencing the inconsistent resistance found in traditional mechanisms. The counterweight system ensures smooth, predictable adjustment behavior.
Solution Approach 2:
The carriage assemblies are designed with dynamic adjustment capabilities that adapt to the loaded weight of each display. The mechanisms provide variable resistance and support forces that automatically adjust based on the display weight and position, ensuring consistent ease of operation regardless of how many displays are mounted or their individual weights. This dynamic behavior eliminates the fixed, inconsistent counterbalancing of traditional designs.
3Adaptability or versatility
If redundant adjustment mechanisms are provided for each display, then independent positioning is achieved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent divides the support system into modular carriage assemblies, where each carriage is a self-contained unit with its own adjustment mechanisms. This segmentation allows each carriage to be manufactured independently using standardized components, simplifying the manufacturing process compared to building entirely custom mechanisms for each display position. The modular design enables mass production of identical carriage units that can be assembled on the common stand structure.
Solution Approach 2:
The patent uses identical or similar carriage assemblies for supporting multiple displays, ensuring uniformity in the adjustment mechanisms across all display positions. This homogeneity in design allows for standardized manufacturing processes, interchangeable parts, and simplified assembly procedures. Each carriage can be produced using the same tooling and assembly methods, significantly reducing manufacturing complexity and cost compared to custom-designed mechanisms for each display.

Function Achieved in This Case
The solution provides a compact, aesthetically pleasing, and efficient way to adjust multiple displays, ensuring smooth alignment and precise positioning, reducing user effort and improving the overall user experience.
Implementation Method 1
The first carriage assembly can comprise a rack and pinion adjustable by the carriage adjuster
Implementation Method 2
a slip clutch to prevent over-torque
Implementation Method 3
the slide having a set of rollers in contact with the first rail and the second rail. Contact between the set of rollers and the first and second rails can constrain movement of the slide to a single principal plane of motion

AI summary
A display stand has two spaced apart legs connected by a horizontal support bar that is attachable to multiple displays. Carriage assemblies allow the stand to adjust the vertical position of the displays, shuttles and rails allow the stand to adjust the horizontal positions of the displays, and a central joint on the support bar allows the stand to adjust the angle between the displays. The carriage assemblies can convert rotational movement of adjustment handles into vertical movement of the support bar that is synchronized at both legs whether the support bar is in a straight or angled configuration. Wheels on the shuttles can provide smooth, consistent contact with rails in the support bar despite changes in the nominal dimensions of the rails. The display stand provides improved smoothness, rigidity, and comfort for the user to support and use multiple displays on a single stand.
