Shelving systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shelving systems in vehicles often have fixed tray spacings that do not accommodate items of varying sizes effectively, leading to inadequate or excessive spacing, and existing locking mechanisms are difficult to access and prone to failure.
Innovation Solution
A shelving system with adjustable side members and a locking mechanism that includes a handle engaging a flange, allowing for customizable tray spacing and improved accessibility and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If trays are equally spaced on the rack according to fixed rack configuration, then the rack structure is simple and stable, but the spacing cannot accommodate items of varying sizes effectively
Solution Approach 1:
The rack structure is made dynamically adjustable through telescopic side members with adjustable extensions. The side members can be extended or retracted to change the spacing between trays, allowing the rack to adapt to different item sizes while maintaining a relatively simple overall structure.
Solution Approach 2:
The side members are segmented into fixed and adjustable extension portions. The adjustable extensions are divided into multiple segments that can be independently positioned, enabling flexible spacing adjustment without requiring complete redesign of the entire rack structure.
2Ease of operation
If conventional locking mechanisms with thumb releases are used, then the locking function is achieved, but the mechanisms are difficult to access and require two hands to operate
Solution Approach 1:
A cable connection is introduced as an intermediary element linking the handle on the container to the locking mechanism on the rack. This allows the user to operate the locking mechanism from a convenient location on the container, improving accessibility and ease of operation while maintaining reliable locking function.
Solution Approach 2:
The locking mechanism is designed to be self-actuating through the cable connection. When the handle is pulled or pushed, the cable automatically transmits the force to engage or disengage the locking mechanism, eliminating the need for manual intervention at the remote locking location.
3Ease of operation
If trays are made to slide relative to the rack for easy access, then item accessibility is improved, but the trays slide at undesired times causing items to move or fall off
Solution Approach 1:
The tray sliding mechanism is made dynamically controllable. The trays can slide when needed for access, but can also be locked in fixed positions when stability is required. The locking mechanism engages with the sliding trays to prevent unwanted movement during transport while allowing intentional sliding when items need to be accessed.

AI summary
A shelving system includes side members that each define a first channel having a slide disposed therein. A cross member extends between and connects the slides. The cross member defines a second channel having a guide member disposed therein. The guide member defines a third channel and a flange. A container includes side walls having a rail. One of the rails is movably disposed in the third channel. The rails include a first locking element and a second locking element. The handle includes a third locking element that engages the first locking element. The handle is movable between a first position in which the second locking element engages the flange and the container is fixed relative to the guide member and a second position in which the second locking element is spaced apart from the flange and the container can translate relative to the guide member.
