Automatic lifting display rack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic lifting display racks experience instability and uneven movement due to unevenly placed articles, causing the bearing plate to tilt and lift unevenly, leading to an unstable lifting process.
Innovation Solution
The automatic lifting display rack incorporates first and second upright posts with rollers at the corners of the lifting platform, guided by an elastic device comprising springs and holders, which ensures levelness and smooth movement by distributing pressure evenly and reducing friction through rollers on the side walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single large spring is used to drive the lifting platform, then the lifting mechanism is simple, but the lifting platform becomes unstable and prone to tilting when articles are placed unevenly
Solution Approach 1:
The single large spring is divided into multiple smaller springs (first spring and second spring) that are distributed at different locations. This segmentation allows each spring to independently support specific regions of the lifting platform, preventing tilting and improving stability while maintaining structural simplicity
Solution Approach 2:
Multiple springs are combined to work together as a unified lifting system. The first spring and second spring are positioned at different locations but cooperate to provide balanced lifting force across the entire platform, achieving both stability and mechanical simplicity
2Device complexity
If the lifting platform moves without guidance structures, then the mechanism is simple, but the platform experiences friction and cannot move smoothly against the side walls
Solution Approach 1:
Rollers are introduced as intermediary elements between the lifting platform and the side walls of the accommodation space. These rollers reduce direct friction contact and enable smooth movement of the platform during lifting and lowering operations
Solution Approach 2:
Rollers are installed at specific critical positions (upper and lower ends of upright posts) rather than along the entire length, providing sufficient guidance and friction reduction only where needed for smooth operation
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 solution maintains the levelness and stability of the lifting platform during up and down movements, preventing tilting and ensuring smooth operation by guiding and restricting the platform with rollers and distributing pressure evenly, thus enhancing the lifting process.
Implementation Method 1
a large spring c is arranged between the bottom of a frame a and a bearing plate b of the conventional display rack. The bearing plate b is moved up and down automatically via the elastic force of the spring c
Implementation Method 2
At least one first roller is mounted to each of the first upright posts. The first roller is configured to roll on a corresponding one of the side walls of the accommodation space

AI summary
An automatic lifting display rack includes a display rack body, an elastic device, and a lifting platform. The display rack body has an accommodation space therein. The elastic device is disposed in the accommodation space. The lifting platform is above the elastic device. Corners of the lifting platform are integrally connected with a plurality of first upright posts that are parallel to side walls of the accommodation space. At least one first roller is mounted to each of the first upright posts. The first roller is configured to roll on a corresponding one of the side walls of the accommodation space. The automatic lifting display rack can improve the smoothness and stability of the lifting platform to be moved up and down.
