Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display stands, such as artist's easels, are prone to instability, often becoming tripping hazards and susceptible to wind, and lack easy adjustment capabilities, requiring complex and costly pulley systems for height and width adjustments, and do not allow for adjustable angling or secure mounting to various surfaces.
Innovation Solution
A display stand with a scalable, adjustable frame assembly using telescoping parts and coupler assemblies that allow for secure mounting to various surfaces, enabling height, width, and angle adjustments, and can be easily disassembled for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional easel designs with tripod legs or single poles are used, then the structure is simple and easy to manufacture, but the stability is poor and the legs are susceptible to displacement and wind
Solution Approach 1:
The stand is divided into multiple telescoping segments that can be adjusted independently. Each vertical support member contains nested telescoping sections that can be extended or retracted to achieve desired height and configuration, allowing the structure to adapt to different stability requirements without requiring a completely different design.
Solution Approach 2:
The stand incorporates dynamic adjustment capabilities through telescoping members that can change length during operation. The adjustable support members allow the user to modify the height and angle of the display area, enabling the structure to maintain stability across various configurations and loading conditions.
2Adaptability or versatility
If complex pulley systems are used for height and width adjustments, then the adjustability is improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent replaces complex pulley systems with a simplified telescoping mechanism. Instead of using ropes, pulleys, and counterweights, the invention uses nested tubular members that slide within each other, allowing height and width adjustments through direct linear motion. This substitution dramatically reduces mechanical complexity while maintaining full adjustability.
Solution Approach 2:
The support members feature dynamic telescoping sections that can be extended or retracted to adjust the height and width of the display area. The adjustable support members include internal telescoping tubes that slide within external tubes, enabling continuous adjustment across a range of dimensions without requiring discrete steps or complex locking mechanisms.
3Weight of moving object
If the display stand is made portable and lightweight, then the ease of transport and storage is improved, but the stability and load-bearing capacity may be compromised
Solution Approach 1:
The stand employs composite construction combining lightweight aluminum or aluminum alloy telescoping tubes with strategic reinforcement elements. The telescoping members use thin-walled but high-strength aluminum sections that provide excellent strength-to-weight ratio, while key connection points and bearing surfaces incorporate reinforced features to maintain load-bearing capacity despite the overall lightweight design.
Solution Approach 2:
The stand is segmented into multiple telescoping sections that can be nested within each other when collapsed, dramatically reducing storage volume and weight for transport. The segmented design allows each section to be optimized for minimal weight while the collective assembly provides the necessary structural integrity through distributed load paths across multiple connection points.
4Adaptability or versatility
If the frame assembly is made adjustable in multiple dimensions, then the adaptability is improved, but the device complexity and number of components increase
Solution Approach 1:
The telescoping support members serve multiple functions simultaneously: they provide structural support, enable height adjustment, enable width adjustment, and allow angular positioning. Each telescoping tube assembly can be independently adjusted in length and angle, allowing a single component to replace what would otherwise require multiple separate adjustment mechanisms in conventional designs.
Solution Approach 2:
The patent merges height adjustment, width adjustment, and angular positioning capabilities into integrated telescoping support members. Instead of having separate mechanisms for each degree of freedom, the design combines these functions into unified adjustable legs where telescoping sections and pivot points work together to provide multi-dimensional adjustability through a coordinated system rather than independent mechanisms.

AI summary
A display stand, for example an artist's easel, consists of an adjustable frame assembly defining a display area for supporting an object. The display area is adjustable to vary its height and width so that it can adjust to the dimensions of an object. The stand includes a set of opposing vertical stand supports adjustably and lockably coupled to opposing sides of the frame assembly so as to vary and lock the height of the frame assembly above a bearing surface. The supports are braceable between the bearing surface and an opposing surface to orient the frame assembly in a user-selected height above the bearing surface. The arrangement allows the display area to be scaled in a rectilinear profile through the range of adjustments.
