Height-adjustable table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tables are inconvenient for height adjustment, requiring manual and laborious processes, and often have limited functionality, failing to meet user needs.
Innovation Solution
A height-adjustable table design featuring a base, height-adjustable legs with movable inner and outer tubes, a motor box, controller, power adapter, and hand controller, allowing for electronic height adjustment of the tabletop through a motor-driven mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual height adjustment is used, then the structure is simple, but the ease of operation deteriorates and time consumption increases
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an electric motor-driven system. The motor box contains a motor that drives the movable inner tube up and down through a driving rod, substituting human physical effort with automated mechanical power. This resolves the contradiction by improving ease of operation while accepting increased device complexity through the addition of motorized components.
2Ease of operation
If motor-driven height adjustment is implemented, then ease of operation improves, but device complexity worsens
Solution Approach 1:
The motor box serves multiple functions: it houses the motor, contains the controller, and integrates the power adapter. This multi-functionality approach consolidates several components into one unit, improving ease of operation through centralized control while mitigating device complexity by reducing the number of separate components that need to be managed.
Solution Approach 2:
The controller automatically manages the motor operation based on hand controller input, eliminating the need for manual mechanical manipulation. The system serves itself by automatically translating user intent into motor action, improving ease of operation while the integrated design keeps complexity manageable.
3Adaptability or versatility
If single-function table design is used, then device complexity is low, but adaptability deteriorates
Solution Approach 1:
The table is designed with height-adjustable legs that enable multiple functions beyond a fixed table. The same leg structure supports both fixed and adjustable height configurations, allowing the table to serve different purposes (dining, working, etc.). This multi-functionality improves adaptability while the unified leg design prevents excessive complexity increase.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient, time-saving, and cost-effective height adjustment with diverse functionality, enhancing user experience and economic value by simplifying the structure and expanding usage possibilities.
Implementation Method 1
The motor drives the movable inner tube of each of the table legs to move up and down through a driving rod

AI summary
A height-adjustable table includes a base, at least two height-adjustable table legs, a retaining frame, a tabletop, a motor box, a controller, a power adapter, and a hand controller. Through the hand controller connected to the controller of the motor box in cooperation with the controller to control the motor, the motor drives the movable inner tube of each table leg to move up and down through the driving rod to achieve the lifting and lowering of the tabletop. The user can adjust the height of the tabletop by simply manipulating the hand controller. The adjustment is more convenient.
