Electric table, leg stand and lightweight beam structure thereof

Solution Overview

Problem

Conventional electric tables with fixed leg frames are heavy and costly due to complex manufacturing processes, making them difficult to transport and adjust for different user heights and body types, leading to increased material and labor costs.

Innovation Solution

A lightweight beam structure for electric tables, comprising a first frame with inner and outer side plates, a second frame with intermediate plates, and telescopic posts connected by screwing elements, which reduces weight and material costs while maintaining stability and allowing for easy installation and adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If rectangular tubes are connected to constitute the beam structure to make the leg frame possess considerable strength, then the strength is improved, but the weight increases and material costs increase

Engineering Contradiction:

ImprovestrengthVSAvoidweight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The beam structure is divided into multiple modular components including first frames, second frames, side wings, and telescopic posts. Each component is made from thin-walled rectangular tubes that can be separately manufactured and assembled, reducing the weight of individual parts while maintaining overall structural strength through modular configuration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The telescopic posts are designed with nested structures where inner tubes slide within outer tubes, allowing the leg frame to adjust height while using minimal material. The nested configuration reduces weight compared to solid structures while maintaining the required load-bearing capacity through the telescopic mechanism.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Strength

If rectangular tubes are connected to constitute the beam structure to make the leg frame possess considerable strength, then the strength is improved, but the material costs increase

Engineering Contradiction:

ImprovestrengthVSAvoidmaterial costs

Core Design Contradiction:

StrengthVSQuantity of substance

Solution Approach 1:

The beam structure is divided into multiple modular components including first frames, second frames, side wings, and telescopic posts. Each component is made from thin-walled rectangular tubes that can be separately manufactured and assembled, reducing the weight of individual parts while maintaining overall structural strength through modular configuration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent uses thin-walled rectangular tubes with optimized wall thickness parameters to achieve the required strength with minimal material consumption. By carefully selecting and adjusting the wall thickness parameter, the structure maintains adequate strength while significantly reducing material costs compared to thick-walled tube configurations.

Inventive Principle:

Principle #35Parameter changes

3Strength

If the leg frame is made heavy to possess considerable strength, then the strength is improved, but the ease of operation deteriorates due to difficulty in shifting and transporting

Engineering Contradiction:

ImprovestrengthVSAvoidease of shifting and transporting

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The beam structure is divided into multiple modular components including first frames, second frames, side wings, and telescopic posts. Each component is made from thin-walled rectangular tubes that can be separately manufactured and assembled, reducing the weight of individual parts while maintaining overall structural strength through modular configuration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The leg frame incorporates telescopic posts with electric motors that enable dynamic height adjustment, allowing the table to adapt to different user needs. This dynamic capability reduces the need for overly robust static structures, thereby reducing weight while maintaining functional strength requirements.

AI summary

A lightweight beam structure includes a first and a second frame. The first frame includes an upper plate, two inner side plates downward bent and extended from two sides of the upper plate, two outer side plates upward bent and extended from two inner side plates respectively and two fixing plates bent and extended from two outer side plates respectively. Each outer side plate is formed outside each inner side plate. A groove is formed between each inner side plate and each outer side plate. The second frame is connected with the first frame and includes a top plate and two intermediate plates downward bent and extended from two sides of the top plate. Each intermediate plate is received in each groove. The top plate is formed over the upper plate. Therefore, the stability is maintained and the weight is reduced so that the material costs may be decreased.
