Solution Overview

Problem

Conventional tables, especially those designed for standing height, often fail to accommodate users of varying heights, making it inconvenient for multiple people to share the same table comfortably and safely.

Innovation Solution

A height-adjustable table with multiple tabletops and a central post, featuring adjustable mechanisms and guards to prevent pinch points, allowing each user to customize their height and ensuring safety and privacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single table height is used for all users, then the table structure is simple and stable, but it cannot accommodate users of varying heights comfortably

Engineering Contradiction:

Improveaccommodation of varying user heightsVSAvoidtable structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The table is divided into multiple independent height-adjustable sections (first tabletop and second tabletop) that can be adjusted individually. Each tabletop has its own height adjustment mechanism, allowing different users to set their preferred heights independently while sharing the same table structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The table incorporates height adjustment mechanisms that allow the tabletops to change position dynamically. The tabletops can be vertically shifted between different height positions to accommodate standing, sitting, or transitional uses, making the table adaptable to various user needs and scenarios.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple height-adjustable mechanisms are added to accommodate different users, then adaptability improves, but the risk of pinch points and safety hazards increases

Engineering Contradiction:

Improveindividual height adjustmentVSAvoidpinch points between tabletops

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

A guard structure is introduced as an intermediary element between the first and second tabletops. This guard prevents direct contact between the moving tabletop edges, eliminating pinch points and providing a safety barrier that protects users from injury while the height adjustment mechanisms operate.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Stability of the object's composition

If height adjustment mechanisms are directly coupled to the base, then structural stability is improved, but the complexity of assembly and maintenance increases

Engineering Contradiction:

Improvetable stabilityVSAvoidassembly complexity

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The height adjustment system is segmented into modular components that are directly coupled to the base. Each tabletop has its own independent adjustment mechanism attached to the base, which simplifies the overall structure by eliminating the need for complex intermediate support structures while maintaining stability.

Inventive Principle:

Principle #1Segmentation

AI summary

A height-adjustable table includes a first tabletop and a second tabletop. A first height adjustment mechanism is configured to vertically shift the first tabletop relative to a support surface on which the table is supported. A second height adjustment mechanism is configured to vertically shift the second tabletop relative to the support surface. The table also includes a base in direct contact with the support surface. Each of the first and second height adjustment mechanisms is directly coupled to the base.
