Storage Rack Platform Positioning Using Recessed Groove Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage racks require labor-intensive installation due to the difficulty in accurately positioning supporting members, which can lead to platform misalignment and increased effort in assembly.
Innovation Solution
A storage rack design featuring platforms with attachment plates that fit into recessed grooves on adjacent supporting pillars, allowing for precise positioning without additional positioning parts, such as pins, thereby simplifying the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If supporting members are individually fixed to pillars using fastening members, then the platform can be supported, but it becomes difficult to position the supporting members accurately in the top-bottom direction, leading to platform misalignment
Solution Approach 1:
The supporting member is divided into a platform and separate attachment plates. The attachment plates are positioned at the ends of the platform and can be independently inserted into slots in the pillars, allowing each plate to be positioned separately while maintaining overall alignment.
Solution Approach 2:
Slots are provided in the pillars that serve as intermediaries for positioning the attachment plates. These slots guide the attachment plates into the correct position in the top-bottom direction, eliminating the need for precise manual positioning while ensuring proper alignment.
2Manufacturing precision
If additional positioning parts such as positioning pins are provided on supporting pillars, then platform positioning accuracy can be improved, but the number of parts and installation steps increases
Solution Approach 1:
The attachment plates serve multiple functions: they support the platform, provide positioning through slot insertion, and enable easy installation. The slots in the pillars serve both as structural features and as positioning guides, eliminating the need for separate positioning pins or other additional positioning parts.
Solution Approach 2:
The positioning function is merged into the attachment plates and slots themselves. Rather than being separate components, the positioning capability is integrated into the existing attachment mechanism, so that the same structural elements that connect the platform to the pillars also provide accurate positioning.

AI summary
A storage rack includes: a plurality of supporting pillars and a platform on which an object to be stored is to be placed. The platform includes a platform body, and a pair of attachment plates each having a plate shape. A pair of surfaces that face each other of a pair of supporting pillars are respectively provided with a pair of recessed grooves into which the pair of attachment plates are inserted. Each recessed groove includes a groove-side abutting portion that extends linearly in a direction orthogonal to the left-right direction. An outer edge of the attachment plate includes a plate-side abutting portion that is parallel with the groove-side abutting portion. The platform is fixed to the pair of supporting pillars such that the plate-side abutting portion abuts against the groove-side abutting portion.
