Solution Overview

Problem

Conventional electric height adjustable tables are cumbersome to assemble and adjust, often requiring screws to be removed and re-fastened, leading to mis-installation errors and a bulky, heavy design that complicates transportation and increases labor and transportation costs.

Innovation Solution

An electric table stand design featuring a beam structure with slidably connected support bars and upright structures, allowing for adjustments without tools and using plastic insulating materials to reduce weight and improve insulation, along with a casing pipe to protect electrical components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional electric height adjustable tables use screw-fixed beam structures with upright structures, then the table provides stable support, but the assembly and adjustment process becomes cumbersome and time-consuming

Engineering Contradiction:

Improvesupport stabilityVSAvoidassembly and adjustment convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the traditional screw-fixed mechanical connection system with a sliding connection system. The upright structures slide along the beam structure within guide grooves, eliminating the need for screws and hand tools. This substitution maintains structural stability while dramatically simplifying assembly and adjustment operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces dynamic adjustability by allowing upright structures to slide freely along the beam structure. The guide grooves provide constrained motion while enabling easy repositioning. This dynamic design allows users to adjust table height and configuration without fixed mechanical fastenings, improving operational convenience.

Inventive Principle:

Principle #15Dynamics

2Reliability

If conventional electric height adjustable tables use a large number of metal parts for stable support, then the table achieves structural stability, but the table becomes bulky and heavy

Engineering Contradiction:

Improvestructural stabilityVSAvoidtable weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The patent employs composite material construction by combining aluminum alloy (for the beam structure) with plastic materials (for upright structures and covers). This composite approach reduces overall weight compared to all-metal construction while maintaining structural stability through the sliding connection mechanism and strategic material placement.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent uses plastic covers (upper and lower covers) as protective shells for the beam structure. These thin film-like covers provide protection and insulation while adding minimal weight. The plastic material replaces heavier metal components in non-structural applications, reducing overall table weight.

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If conventional electric height adjustable tables use multiple screws for locking and assembling, then the table achieves secure connections, but the assembly process requires significant labor and time

Engineering Contradiction:

Improveconnection securityVSAvoidassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the screw-based mechanical fastening system with a sliding insertion system. Upright structures slide into place along guide grooves and are retained by the groove geometry itself, eliminating the need for multiple screws and hand tools. This substitution reduces assembly time while maintaining connection security through the guide groove constraint.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If conventional electric height adjustable tables use traditional beam structures with screws, then the table provides robust support, but assembly errors such as mis-installation or misalignment occur frequently

Engineering Contradiction:

Improvesupport capabilityVSAvoidassembly accuracy

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The guide grooves in the beam structure provide self-aligning features that guide upright structures into the correct position during assembly. This self-service mechanism ensures proper alignment without requiring user skill or precision, eliminating mis-installation errors while maintaining robust support capability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The guide grooves act as an intermediary element between the beam structure and upright structures. They mediate the connection by providing a constrained path that ensures proper alignment and positioning, preventing assembly errors while enabling easy installation.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An electric table stand for simple assembly and adjustment includes a beam structure (10), support bars (20), and upright structures (30). Each of the support bars (20) includes a base (21) and a plurality of arms (211, 212, 213) extended from the base (21), wherein an accommodating space (A) is defined by the base (21) and the arms (211, 212, 213). One arm (213) of each of the support bars (20) supports one end of the beam structure (10), and the beam structure (10) is operatively moved in or out of the accommodating space (A). The upright structures (30) are connected to the support bars (20). Accordingly, it is easy to adjust and position each support bar (20) and each upright structure (30) on the beam structure (10).
