Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional food serving carts with cooking modules are cumbersome for transportation and storage due to their large size.
Innovation Solution
A foldable food serving cart design featuring a stand with rotatable side stands, a sliding horizontal beam, and a detachable supporting frame that reduces in size by folding, allowing the cooking modules and base stand to be separated into smaller parts for easier handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the food serving cart is designed with cooking modules and a complete supporting frame, then the functionality and cooking capability are improved, but the size and volume increase making transportation and storage difficult
Solution Approach 1:
The supporting frame is divided into a stand body and two side stands that can be separated and folded. The cooking modules are detachably connected to the stand body, allowing them to be separated during folding. This segmentation enables the frame to be collapsed into a compact configuration while maintaining full cooking functionality when assembled.
Solution Approach 2:
The side stands are designed with rotatable connections to the stand body, allowing them to pivot and fold inward. The first horizontal beam is slidably connected to the side stands, enabling dynamic adjustment and compact folding. This dynamic mechanism allows the frame to transition between an expanded operational state and a compact storage state.
2Reliability
If the food serving cart is designed as a conventional fixed structure, then the stability and cooking capability are maintained, but the transportation and storage become cumbersome
Solution Approach 1:
The base stand is separated from the supporting frame, with the frame being detachably connected to the base stand. This allows the frame to be removed and folded separately from the base stand during transportation, while ensuring stable reconnection when assembled for cooking operations.
Solution Approach 2:
The rotatable connections between the side stands and stand body, combined with the sliding horizontal beam, create a dynamic folding mechanism that maintains structural integrity during transformation. This allows the cart to be easily collapsed for transport while maintaining cooking stability when assembled.
3Ease of operation
If the side stands are designed to be rotatably connected for folding, then the foldability and storage convenience are improved, but the structural complexity increases
Solution Approach 1:
The side stands are rotatably connected to the stand body through simple pivot joints, and the horizontal beam is slidably connected to the side stands. These dynamic connections use straightforward mechanical mechanisms that enable easy folding without requiring complex assembly or disassembly procedures, balancing operational convenience with structural simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The foldable design significantly reduces the cart's size when folded, making it more convenient for transportation and storage while maintaining functionality.
Implementation Method 1
the first side stand and the second side stand respectively turn inward towards each other
Implementation Method 2
the first horizontal beam slides from an end of the side stands towards the stand body and abuts to the stand body
Implementation Method 3
the supporting frame is detachably connected on top of the base stand

AI summary
A foldable food serving cart, including a stand, side stands, electric circuit assembly and a base stand; the stand includes a stand body. The side stands include a first side stand and a second side stand, which are respectively rotatably connected to left and right sides of the stand body, and provided with a sliding groove on their top parts; the stand further include a first horizontal beam where its left and right sides are respectively slidably connected to the sliding grooves. A supporting frame is defined by the stand, the first horizontal beam, the first side stand and the second side stand for cooking modules, which are powered by the electric circuit assembly, to be placed on its top part. The supporting frame is detachably connected on top of the base stand; wheels are provided on a bottom part of the base stand.
