Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support structures, such as barbecue grills and drying racks, lack portability and ease of setup for providing a horizontal support surface with multiple openings, making them inconvenient for various applications.
Innovation Solution
A collapsible support stand with a first and second support section, featuring pivotably connected frame links and foldable legs, allowing the support surface to be extended or retracted by sliding bars through aligned holes, and foldable for compact storage, facilitating portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a support structure is made portable and collapsible, then ease of transport and storage is improved, but structural stability and support capacity may deteriorate
Solution Approach 1:
The support stand is divided into multiple collapsible frame sections that can be separated and folded independently. Each frame includes vertical legs with horizontal crossbars that can be segmented for compact folding, allowing the structure to be disassembled into manageable sections for portability while maintaining stability when assembled.
Solution Approach 2:
The support stand employs dynamic folding mechanisms with pivot joints and telescopic bars that allow the structure to transition between extended stable configurations and collapsed compact states. The telescopic bars with sliding mechanisms enable adjustable frame dimensions while maintaining structural rigidity during use.
2Area of stationary object
If the support surface is extended horizontally to provide adequate support area, then support capacity is improved, but device complexity and difficulty of collapsing increases
Solution Approach 1:
The support surface is segmented into multiple parallel bars spaced apart to form a grid-like structure. These bars are attached to the frame at multiple points along their length, allowing the support surface to extend horizontally for adequate area while the segmented bar structure folds compactly with the frame without requiring complex mechanisms.
Solution Approach 2:
The support surface bars are combined with the frame structure through multiple attachment points, integrating the support function with the collapsible frame mechanism. This merging allows the support surface to be extended horizontally when needed while automatically collapsing with the frame when folded, reducing overall device complexity.
3Adaptability or versatility
If multiple openings are provided in the support surface for heat exposure or substance passage, then functionality is improved, but structural strength may deteriorate
Solution Approach 1:
The support surface is designed with multiple openings between the parallel bars, creating a porous structure that allows heat exposure from below and passage of substances such as air, water, or oil. The bars themselves are positioned and dimensioned to maintain structural strength while providing adequate openings for the intended functions.
Solution Approach 2:
The support surface has varying local qualities with bars positioned to provide both structural strength in critical areas and openings in areas where heat exposure or substance passage is needed. The spacing and dimensions of bars can be adjusted locally to balance structural integrity with functional requirements for heat and fluid passage.

AI summary
A collapsible support stand is disclosed. The support stand includes a first support section and a second support section. The first support section includes a first side frame and a plurality of first bars extending perpendicularly from the first side frame. The second support section includes a second side frame parallel to the first side frame, a first centre frame defining a plurality of holes, and a plurality of second bars extending between the second side frame and the first centre frame, wherein axial movement of the plurality of first bars through the plurality of holes moves the first support section between an extended position and a retracted position relative to the second support section. The support stand includes a pair of first foldable legs connected to the first side frame and a pair of second foldable legs connected to the second side frame.
