Adjustable shelf
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable shelves in kitchens and storage cabinets fail to maximize space utilization, often leading to wasted space and difficulty in accessing items due to their fixed designs and inability to accommodate containers of varying shapes and sizes, especially in lower cabinets where pipes and fixtures obstruct visibility and retrieval.
Innovation Solution
A U-shaped adjustable shelf system with slidable L-shaped portions and adjustable legs, allowing for customizable length and height adjustments without requiring the removal of any components, enabling easy installation and optimal storage of various-sized containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed rectangular shelf is used in cabinets, then the shelf structure is simple and easy to manufacture, but it wastes significant storage space and makes it difficult to access items stored in the back
Solution Approach 1:
The shelf is divided into multiple sections with different depths. The front section has a greater depth than the back section, creating a stepped configuration that allows containers of various sizes to be stored efficiently without wasting space, while maintaining structural simplicity for easy manufacturing
Solution Approach 2:
The shelf transitions from a traditional single-plane rectangular design to a multi-level stepped design with varying depths in different sections. This dimensional variation allows optimal use of vertical and horizontal space within the cabinet, improving storage capacity without complicating the manufacturing process
2Productivity
If containers are stacked vertically to maximize space, then space utilization improves, but visibility and access to items become difficult
Solution Approach 1:
The shelf creates distinct storage zones with different depths. Smaller containers can be placed in the front section while larger containers occupy the back section, allowing all items to be visible and accessible without vertical stacking, thus maintaining both space utilization and visibility
3Productivity
If the shelf depth is increased to store more items, then storage capacity improves, but items in the back become harder to reach
Solution Approach 1:
The shelf is segmented into front and back sections with different depths. Frequently accessed items are placed in the shallower front section that is easily reachable, while less frequently accessed items occupy the deeper back section. This segmentation maintains high storage capacity while ensuring easy access to commonly used items

AI summary
An adjustable shelving system comprised of a plurality of interconnecting shelf sections including a front side shelf section, a right side shelf section and a left side shelf section. At least one of the three shelf sections is independently adjustable in length to adjust a length and/or width of the shelving system and are supported by legs that are also independently adjustable in height.
