Liftable table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tables lack adjustability, forcing users to adjust their chair height to maintain a comfortable viewing position with computers, leading to potential health issues from prolonged sitting and limiting usability when standing.
Innovation Solution
A liftable table with a frame, fixing board, lifting device, and table board that can be adjusted upwardly or downwardly, allowing users to change positions comfortably while using a computer, equipped with a driving set and crossing sets connected to a motor for smooth height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the table height is fixed, then the structure is simple and stable, but the user cannot adjust the monitor height to comfortable positions when standing
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed table structure into a dynamically adjustable one. The table board is made movable through the lifting device with crossing sets that can extend and fold, allowing the table height to change from a static state to a dynamic, adjustable state. This resolves the contradiction by enabling height adaptability while managing structural complexity through controlled mechanical movement.
Solution Approach 2:
The crossing sets are designed to be nested within the holding seat when not in use. The crossing sets can be extended from or folded in the receiving space of the holding seat, creating a compact configuration when height adjustment is not needed. This nesting approach allows the table to maintain a simple appearance and structure at rest while providing adjustability when required.
2Ease of operation
If the user sits for long periods to use the computer, then the table height remains comfortable, but health damages occur from prolonged sitting
Solution Approach 1:
The lifting device enables dynamic height adjustment of the table board, allowing users to switch between sitting and standing positions. This dynamic capability directly addresses the health issue by enabling posture changes, while the driving set ensures smooth transitions between positions to maintain comfort during operation.
3Adaptability or versatility
If a lifting device with crossing sets is added to enable height adjustment, then the table becomes adaptable to different positions, but the device complexity increases
Solution Approach 1:
The crossing sets are designed to fold into the receiving space of the holding seat, creating a nested configuration that minimizes the structural footprint. When the crossing sets are folded in, they occupy minimal space within the holding seat, effectively hiding the complexity of the lifting mechanism while maintaining the adaptability capability when needed.
Solution Approach 2:
The lifting device is segmented into modular components: the holding seat, the crossing sets, and the driving set. This segmentation allows each component to be optimized independently and simplifies the overall structure by breaking down the complex height adjustment function into manageable, separable parts that can work together systematically.

AI summary
A liftable table has a table frame, a fixing board, a lifting device, and a table board. The table frame has a main frame and a holding seat. The holding seat is deposited on the main frame. The fixing board is mounted on the main frame. The lifting device is deposited on the holding seat and has a driving set and at least one crossing set. The crossing set is extended from or folded in the receiving space of the holding seat, and is connected to and driven by the driving set. The table board is deposited on the crossing set to move upwardly or downwardly. A user views and operates a computer put on the table board with a sitting or a standing posture, and this prevents the user from using the computer with the sitting posture for a long time and avoids damages to the user's health.
