Threaded Mounting Rod Shelf Assembly for Independent Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-end refrigerators with lifting racks for shelf adjustment are costly and difficult to install, affecting aesthetics and space utilization.
Innovation Solution
A shelf assembly with a set of mounting rods featuring external threads and matching internal thread holes on movement components, allowing independent shelf adjustment while ensuring load-bearing stability through joint thread constraints, and optionally including guide rods and sliding blocks for additional support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a set of lifting racks is provided for each shelf to enable independent adjustment, then each shelf can be adjusted independently, but the cost increases and installation difficulty increases
Solution Approach 1:
The patent merges multiple lifting racks into a single shared lifting rack structure. Instead of providing separate lifting racks for each shelf, one lifting rack serves multiple shelves simultaneously, reducing the total number of components while maintaining independent adjustability of each shelf through individual positioning mechanisms.
Solution Approach 2:
The lifting rack is designed with multi-functionality to serve multiple shelves. A single lifting rack structure can support and adjust multiple shelves at different heights, making one component perform the function of what would traditionally require multiple separate components.
2Ease of operation
If a set of lifting racks is provided for each shelf to enable independent adjustment, then each shelf can be adjusted independently, but the installation difficulty increases in limited space
Solution Approach 1:
By combining multiple lifting functions into a single integrated lifting rack structure, the number of installation points and mounting operations is reduced. The unified structure requires fewer installation steps compared to installing separate lifting racks for each shelf, thereby reducing installation difficulty in limited refrigerator space.
3Ease of operation
If a set of lifting racks is provided for each shelf to enable independent adjustment, then each shelf can be adjusted independently, but the aesthetics are affected
Solution Approach 1:
The consolidated lifting rack structure reduces visual clutter compared to having multiple separate lifting racks. The unified design creates a cleaner, more streamlined appearance inside the refrigerator, improving aesthetics while still enabling independent shelf adjustment through the shared mechanism.
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 cost-effective, easy installation, and independent shelf adjustment with a concise appearance, preventing shelves from sliding due to load-bearing constraints, thus addressing the challenges of cost, complexity, and aesthetics in existing solutions.
Implementation Method 1
either in the process of adjusting the height of the shelves or when the shelves are fixed, the shelves will not slide down along the mounting rods because of load bearing under the joint constraint of the external threads of the mounting rods and the internal threads of the movement components

AI summary
Provided are a shelf assembly and a storage cabinet, which relate to the technical field of storage apparatuses. The shelf assembly includes: a plurality of shelves, mounting rods, the outer peripheral walls of which are provided with external threads in the axial direction, moving members corresponding to the shelves, and driving members corresponding to the moving members. The moving members are connected to the corresponding shelves; internal thread holes in threaded fit with the mounting rods are formed on the moving members; and the driving members are connected to the corresponding moving members and are used for driving the moving members to rotate. The storage cabinet includes a cabinet body and the shelf assembly arranged in the cabinet body.
