Desktop lifting table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing desktop lifting tables face challenges due to unreasonably arranged lifting and driving mechanisms, making them difficult to design and manufacture within cost and product volume constraints, while also struggling with stability and locking force issues.
Innovation Solution
A desktop lifting table design featuring a lifting mechanism with hingedly connected lifting arms and a driving mechanism using a gas spring and manipulating member, which allows for adjustable height and stable operation, along with a tabletop supporting member to enhance locking force, particularly at low positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the lifting mechanism is arranged along the length direction close to an edge of the tabletop, then the stability during lifting is improved, but the locking force becomes insufficient when the tabletop is lowered to lower positions
Solution Approach 1:
A tabletop supporting member is introduced as an intermediary component to provide additional support when the tabletop is at lower positions. This supporting member acts as a mediator between the tabletop and the lifting mechanism, compensating for the insufficient locking force of the gas spring at low positions without affecting the stability improvement gained by the edge-arranged lifting mechanism.
2Force
If a gas spring with better performance or larger size is used to achieve sufficient locking force, then the locking force is improved, but the cost and product volume increase
Solution Approach 1:
The support function is segmented between the gas spring and the tabletop supporting member. The gas spring handles the lifting and locking at higher positions, while the tabletop supporting member handles the support at lower positions. This segmentation allows the use of a smaller, more cost-effective gas spring while still achieving sufficient overall locking force and support.
3Stability of the object's composition
If the lifting mechanism is arranged along the length direction close to an edge of the tabletop, then the stability is improved, but it becomes difficult to solve the driving and locking of sliding of the lifting arms
Solution Approach 1:
The gas spring seat is designed to slide along with the second arm end along the bottom surface of the tabletop, allowing the driving mechanism to automatically follow the movement of the lifting arm. The manipulating member arranged at the edge facilitates self-service operation, reducing the complexity of control while maintaining stability.
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
The design provides a stable, easily manufacturable, and cost-effective desktop lifting table with strong locking force, enabling smooth height adjustment and preventing tipping, even with a smaller gas spring, thus meeting lifting requirements effectively.
Implementation Method 1
The driving mechanism includes a gas spring, a gas spring seat and a manipulating member, wherein the gas spring seat is connected to the second arm end, and the gas spring has a fixing end connected to the gas spring seat and a manipulating end connected to the manipulating member

AI summary
The utility model belongs to the technical field of office and household articles, and particularly, relates to a desktop lifting table. The desktop lifting table includes a tabletop and a lifting mechanism that acts to raise or lower the tabletop, the first arm end of the lifting arm set is hingedly arranged and the second arm end thereof is slidably arranged; and a driving mechanism connected to the second arm end includes a gas spring, a gas spring seat and a manipulating member. The desktop lifting table of the utility model is provided with a gas spring seat below the tabletop to accommodate the gas spring so that its minimum height is very low.
