Solution Overview

Problem

Existing power-driven table stands face issues with complex assembly, heavy weight, large size, and inconsistent height adjustments due to manual operation of pneumatic cylinders, which complicates user experience and increases assembly time.

Innovation Solution

A collapsible power-driven table stand design featuring a supporting body with pivotally attached first and second stands, each driven by extendable rods and a controller for synchronous actuation, allowing for easy assembly, compact structure, and reduced material usage, with driving members and controllers concealed for aesthetic appeal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If pneumatic cylinders are used for table lifting, then assembly is simplified, but height adjustment precision deteriorates due to high-speed lifting and manual operation requirements

Engineering Contradiction:

Improveassembly simplicityVSAvoidheight adjustment precision

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent replaces the pneumatic cylinder system with an extendable rod mechanism driven by a power-driven cylinder. This substitution maintains the simplified assembly advantage while eliminating the high-speed lifting issue, as the extendable rod provides controlled, precise movement for height adjustment without requiring manual intervention during operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The extendable rod acts as an intermediary between the power-driven cylinder and the table top. It translates the controlled linear motion of the power-driven cylinder into precise vertical adjustment of the table, enabling accurate height control while maintaining structural simplicity and ease of assembly.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If power-driven cylinders are used for table lifting, then height adjustment precision is improved, but device complexity and assembly time increase

Engineering Contradiction:

Improveheight adjustment precisionVSAvoidstructure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent segments the lifting mechanism into distinct functional components: the power-driven cylinder provides controlled force, the extendable rod transmits motion, and the connecting devices facilitate assembly. This segmentation allows each component to be optimized independently, achieving precise height adjustment while keeping the overall structure manageable and assembly straightforward through modular construction.

Inventive Principle:

Principle #1Segmentation

3Manufacturing precision

If power-driven cylinders are used for table lifting, then height adjustment precision is improved, but weight and size increase

Engineering Contradiction:

Improveheight adjustment precisionVSAvoidstand weight

Core Design Contradiction:

Manufacturing precisionVSWeight of moving object

Solution Approach 1:

The patent employs a dynamic extendable rod mechanism that can extend and retract as needed. When not in use, the rod retracts to minimize the overall size and weight of the stand. During operation, it extends to provide the necessary lifting capability with precise control, thus achieving accurate height adjustment without permanently increasing the stand's weight and footprint.

Inventive Principle:

Principle #15Dynamics

AI summary

There is disclosed a collapsible power-driven table stand includes a supporting body (10) of an elongated shape, a first stand (20)having a first driving member (21) and a plurality of first extendable rods (22) driven by the first driving member (21) to move axially relative to each other and a second stand (30) having a second driving member (31) and a plurality of second extendable rods (32) driven by the second driving member (31) to move axially relative to each other. The first diving member (21) is pivotally attached to one end of the supporting body (10)and the second diving member(31) is also pivotally attached to another end of the supporting body (10)in order to allow both the first and second stands (20, 30) to extend/collapse relative to the supporting body (10). Accordingly, the assembly of the collapsible power-driven tableis simplified and the overall size thereof is reduced.
