Modular Display Bar Assembly for Stable Tool-Free Sign Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display methods for signs and objects are often cumbersome, require tools, and detract from the object's visibility or aesthetic appeal, while lacking stability under windy conditions.
Innovation Solution
A display easel apparatus comprising first and second display bars with through holes and fasteners, supported by upright tubular members and yard stakes, allowing for secure and adjustable display of objects without obstructing visibility, using a rigid block or wire bracket with retainer arms and hooks to support display objects like corrugated plastic sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional display methods (pedestals, bolted posts) are used, then stability and support are achieved, but the display becomes heavy, cumbersome to move, and requires tools for assembly
Solution Approach 1:
The display structure is divided into separate modular components: display bars with pre-drilled holes, tubular supports, and fasteners. These segments can be independently handled and assembled without tools by simply inserting and securing the components through the holes, eliminating the need for heavy integrated structures or tool-based assembly
Solution Approach 2:
Tubular supports act as intermediary elements that connect the display bars to the ground or mounting surface. These intermediaries provide stability while maintaining a lightweight, tool-free assembly process, as they can be simply inserted through the display bar holes and secured with fasteners
2Reliability
If traditional display methods are used, then support is achieved, but the display structure is cumbersome and expensive
Solution Approach 1:
The structure is segmented into simple, standardized components with uniform rectangular cross-sections and pre-drilled holes. This segmentation reduces manufacturing complexity and allows for easier assembly while maintaining adequate support capability through the modular design
Solution Approach 2:
The display bars use a standardized rectangular cross-section with specific hole patterns, transforming the design into a parameter-based system that simplifies manufacturing and assembly. This standardization reduces structural complexity while ensuring adequate support through optimized dimensional parameters
3Illumination intensity
If display structures are added to elevate signs, then visibility is improved, but the support structure detracts from the aesthetic appeal of the display
Solution Approach 1:
The display bars use a thin-walled tubular design that provides structural support while minimizing visual obstruction. The thin-walled construction allows light to pass through more freely and reduces the bulkiness of the support structure, improving both visibility and aesthetic appeal while maintaining adequate support capability
4Ease of operation
If simple display supports are used, then ease of assembly is improved, but stability under windy conditions deteriorates
Solution Approach 1:
The display bars are connected to multiple tubular supports at different locations, merging multiple support points into a unified stable structure. This distributed support system provides resistance to wind forces while maintaining the simple, tool-free assembly characteristic of each individual connection

AI summary
An apparatus includes first and second display bars, each display bar having a rectangular cross-section, each display bar having a plurality of first through holes each having a first diameter for receiving a first tubular support therethrough, and each display bar having a plurality of second through holes each having a second diameter for receiving a fastener; a first upright tubular support receivable through one of the first through holes in the first display bar for vertically supporting the first display bar; a second upright tubular support receivable through one of the first through holes in the second display bar for vertically supporting the second display bar; and a fastener secured through one of the second through holes in the first display bar and one of the second through holes in the second display bar to secure the first and second display bars together.
