Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leg stands for electric tables require complex processes and heavy materials to achieve strength, leading to high weight and increased material costs, making them difficult to transport and assemble efficiently.
Innovation Solution
A beam structure composed of a first and second frame, where the first frame includes an inner bottom plate and side plates with embedded outer connecting plates, and the second frame is movably connected, allowing for reduced weight and easier assembly by utilizing coplanar properties and rigidity, enabling adaptation to different table lengths and specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rectangular tubes are connected to constitute the beam structure, then the strength is improved, but the weight increases and material costs increase
Solution Approach 1:
The beam structure is divided into multiple frames (first frame, second frame, etc.) that are connected together. Each frame is a separate component that can be manufactured independently and then assembled, allowing for weight reduction while maintaining structural strength through the distributed framework design
Solution Approach 2:
The patent employs composite construction by combining multiple frame structures with different functions (support frames, connecting frames) to create a beam structure that achieves required strength with reduced material usage compared to solid rectangular tube construction
2Strength
If rectangular tubes are connected to constitute the beam structure, then the strength is improved, but the manufacturing process becomes complicated
Solution Approach 1:
The complex beam structure is segmented into standardized frame modules that can be manufactured using consistent processes. This modular approach simplifies manufacturing by repeating the same fabrication steps for each frame rather than creating custom connections for rectangular tubes
Solution Approach 2:
The frame structures are designed to nest or connect in a standardized manner, with inner frames positioned within or alongside outer frames. This nested arrangement simplifies the manufacturing process by using uniform connection methods across all frame interfaces
3Strength
If heavy materials are used to achieve strength, then the strength is improved, but the material costs increase
Solution Approach 1:
By dividing the beam structure into multiple lightweight frame segments, the patent reduces the total quantity of material needed compared to a single heavy rectangular tube construction, while maintaining strength through the distributed structural framework
Solution Approach 2:
The composite frame structure uses optimized material distribution across multiple components rather than heavy uniform materials, achieving required strength with reduced overall material quantity and lower costs
4Strength
If the leg stand is made heavy, then the strength is improved, but the ease of shifting and transporting deteriorates
Solution Approach 1:
The leg stand is divided into modular frame components that can be easily assembled and disassembled, significantly improving ease of shifting and transporting while maintaining structural strength through the framed construction

AI summary
The disclosure is a beam structure for a leg stand of an electric table, which includes a first frame and a second frame. The first frame includes an inner bottom plate, an inner side plate and an inner embedding plate. The inner embedding plate is formed on outside of the inner side plate. The inner embedding plate includes an exposed section. The second frame is movably connected with the first frame. The second frame includes an outer bottom plate, an outer side plate and an outer connecting plate. The inner bottom plate is formed above the outer bottom plate. The inner side plate is formed on inside of the outer side plate. The inner embedding plate is correspondingly embedded in the outer connecting plate. The exposed section is exposed from the outer connecting plate.
