Supporting arm for a storage rack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage racks with single-point connections between supporting arms and vertical columns or back plates lack structural strength, causing instability and potential breakage when holding heavy goods, affecting both the structural integrity and service life.
Innovation Solution
A supporting arm design featuring a body with a first tab and a second tab for engaging the frame body structure through snap connections, providing a stable two-point force reception and enhanced structural support, along with a reinforcement rod and fixing block for additional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single-point connection structure is used between supporting arms and vertical columns, then the device complexity is reduced and ease of manufacture is improved, but the structural strength and stability deteriorate when holding heavy goods
Solution Approach 1:
The supporting arm is divided into multiple functional segments: a body portion, a supporting portion for the board, a first tab for engagement, a second tab for engagement, and a vacant portion. This segmentation allows the single supporting arm to achieve multi-point connection capabilities, resolving the contradiction by maintaining manufacturing simplicity while improving structural strength through distributed load-bearing points.
Solution Approach 2:
The invention transitions from a single-point connection (one-dimensional connection point) to a multi-point connection system by adding tabs extending in different spatial directions. The first tab and second tab engage with vertical columns at different locations, creating a two-dimensional connection pattern that enhances structural strength without significantly increasing manufacturing complexity.
2Device complexity
If a single-point connection structure is used between supporting arms and vertical columns, then the device complexity is reduced, but the stability deteriorates causing shaking and potential breakage when holding heavy goods
Solution Approach 1:
The supporting arm is segmented into distinct functional parts including the body, supporting portion, first tab, second tab, and vacant portion. This segmentation enables the structure to achieve stable multi-point engagement with vertical columns while maintaining relatively simple manufacturing processes, thus resolving the contradiction between device complexity and stability.
Solution Approach 2:
The invention merges multiple connection functions into a single supporting arm component. The first tab and second tab work together to provide dual engagement points with the vertical columns, combining the functions of multiple connection elements into one integrated part. This merging approach improves stability without proportionally increasing device complexity.
3Strength
If multiple tabs are added to create double engagement connections, then the structural strength and stability are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
Multiple connection functions are merged into a single supporting arm component. The first tab and second tab are integrated into one piece with the body and supporting portion, achieving double engagement connection without requiring separate connection components. This merging approach improves structural strength while minimizing the increase in device complexity.
Solution Approach 2:
The supporting arm is designed as a multi-functional component that simultaneously provides board support, multi-point engagement with vertical columns, and structural stabilization. The single component performs multiple functions that would traditionally require several separate parts, thereby improving strength without proportionally increasing device complexity.
