Existing height-adjustable tables lack ease of assembly and flexibility in use, with potential for user error during assembly and limited adjustability, which can lead to incorrect installation and reduced usability.

Innovation Solution

A height-adjustable table design featuring a telescopic frame with a fixed and movable part, utilizing electric motor-driven rods and profiles for smooth height adjustment, allowing for easy assembly and multiple width settings, with pre-assembly and packaging to minimize errors and enhance user convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional assembly methods are used for height-adjustable tables, then manufacturing is straightforward, but assembly complexity increases and user error risk increases

Engineering Contradiction:
Improveease of assemblyVSAvoidassembly complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-assembling the frame and attaching the motor to the frame before shipping. This pre-assembly of critical components simplifies the final user assembly process while maintaining manufacturing efficiency. The motor is pre-mounted on the frame in a specific orientation, and the driving rod is pre-inserted, eliminating multiple separate assembly steps for the user.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments the table into modular components: the frame with pre-installed motor, the columns with integrated gearboxes, and the connecting elements. This segmentation allows each component to be manufactured and prepared independently, then easily assembled by the user using simple connecting elements that require minimal tools and expertise.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If fixed frame construction is used, then structural stability is maintained, but adaptability to different table widths is limited

Engineering Contradiction:
Improvetable width adjustabilityVSAvoidframe stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies dynamics by making the frame extensible through telescopic columns that can adjust between different width configurations. The frame transitions from a fixed structure to a dynamic, adjustable structure that maintains stability through mechanical connection elements and proper structural design, allowing the same frame to accommodate various table widths while preserving structural integrity.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If manual height adjustment mechanisms are used, then device complexity is reduced, but ease of operation and comfort are diminished

Engineering Contradiction:
Improveheight adjustment comfortVSAvoiddrive mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical height adjustment with an electric motor-driven system. The motor is mounted on the frame and connected to the columns via driving rods and gearboxes, enabling automated height adjustment. This substitution eliminates the need for manual cranking or tool-based adjustment, significantly improving ease of operation and user comfort despite the increased mechanical complexity of the drive system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Loss of time

If complete assembly is required at installation site, then adaptability to different locations is maximized, but assembly time and error risk increase

Engineering Contradiction:
Improveassembly timeVSAvoidinstallation flexibility
Core Design Contradiction:
Loss of timeVSAdaptability or versatility

Solution Approach 1:

The patent applies preliminary action by performing significant assembly work at the manufacturing stage rather than at the installation site. The frame is pre-assembled with the motor attached, and the driving rod is pre-inserted through the frame. This reduces the on-site assembly to simple connection tasks, dramatically reducing assembly time and minimizing the risk of user error while maintaining the ability to install the table in various locations.

Inventive Principle:
Principle #10Preliminary action
