Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liftable tables face challenges in height adjustment due to the fast and declining nature of pneumatic cylinders, requiring improper force exertion and multiple operations, and electric cylinders require complex assembly with many screws, leading to high labor and time costs and potential errors.
Innovation Solution
A liftable table foot frame with a linking mechanism that connects a side wing and a post, allowing for easy assembly by rotating the post to position the side wing, using a horizontal frame body, post, and linking mechanism with inserting blocks and buffer portions for flexible deformation and secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electric cylinders are used for height adjustment, then height adjustment convenience is improved, but assembly complexity increases due to large amount of screws required
Solution Approach 1:
The foot frame is divided into modular components (horizontal frame body, post, side wing) that can be assembled through simple linking mechanisms rather than multiple screw connections. The inserting blocks with buffer portions create self-aligning modular joints.
Solution Approach 2:
The linking mechanism with buffer portions enables self-aligning and self-positioning during assembly. When inserting blocks are inserted into the horizontal rod, the buffer portions automatically deform to tense and position the components, eliminating the need for precise manual alignment and multiple screw fastenings.
2Ease of operation
If electric cylinders are used for height adjustment, then height adjustment convenience is improved, but labor cost and time cost increase due to complicated assembly process
Solution Approach 1:
The buffer portions are pre-formed with flexible deformation characteristics that enable automatic tensioning and positioning during assembly. The inserting blocks are pre-configured with positioning features that guide them into the horizontal rod, preparing the components for quick connection without requiring time-consuming alignment and fastening operations.
Solution Approach 2:
The linking mechanism performs self-positioning and self-tensioning through the flexible deformation of buffer portions. When inserting blocks are inserted, they automatically tense and position the post and side wing components, eliminating the need for skilled workers to perform complex alignment and screwing operations, thereby significantly reducing assembly time and labor cost.
3Ease of operation
If electric cylinders are used for height adjustment, then height adjustment convenience is improved, but assembly error risk increases due to unskilled workers difficulty
Solution Approach 1:
The linking mechanism with buffer portions creates a self-aligning and self-positioning system that automatically ensures correct assembly geometry. The flexible buffer portions deform to accommodate minor misalignments and then tense to lock the components in the correct position, making the assembly process tolerant to variations in worker skill level while maintaining high assembly precision.
Solution Approach 2:
The buffer portions are designed with specific flexible deformation characteristics that allow them to accommodate a range of insertion angles and positions during assembly, then lock into a precise final position. This parameter flexibility during the assembly process ensures that even unskilled workers can achieve correct assembly without requiring high precision manual alignment.
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
Simplifies the assembly process, reduces labor and time costs, and allows unskilled workers to achieve effective assembly, enabling precise height adjustment without complex screwing processes.
Implementation Method 1
By the property of flexible deformation of the buffer portion, the first connecting member and the second connecting member can be firmly fastened to the sides of the base plate
Implementation Method 2
One end of the post pivotally connects to the horizontal rod
Implementation Method 3
The linking mechanism connects the post and the side wing. When the post is turned out relative to the horizontal rods, the inserting blocks are driven toward the horizontal rod through the linking mechanism

AI summary
A liftable table foot frame (1) that is easily assembled includes a horizontal frame body (10), a post (20), a side wing (30) and a linking mechanism (40). The horizontal frame body (10) includes a horizontal rod (11). One end of the post (20) pivotally connects to the horizontal rod (11). The side wing (30) includes a plate body (31) and inserting blocks (32) connected to the plate body (31). The inserting blocks (32) separately couple with an end of the horizontal rod (11). The linking mechanism (40) connects the post (20) and the side wing (30). When the post (20) is turned out relative to the horizontal rod (11), the inserting blocks (32) are driven toward the horizontal rod (11) through the linking mechanism (40) to tense and position. Thus, easiness and convenience of assembling can be increased.
