Shelving Upright Reinforcement With Distributed Fixing Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shelving uprights in storage warehouses are prone to deformation and breakage due to shocks from forklifts, leading to safety risks and the need for costly and disruptive replacement, with existing reinforcement devices concentrating force at fixing zones, risking further breakage.
Innovation Solution
A shelving reinforcement device with a profiled structure and load distribution means, such as tongues with side slots, to distribute force along the length of the upright, reducing load concentration at fixing zones and enhancing mechanical resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a mechanical reinforcement element is installed to strengthen the upright, then the reinforcement and straightening effectiveness is improved, but the load concentration at fixing zones increases causing breakage risk
Solution Approach 1:
The patent introduces a load distribution plate that extends the force distribution from a point contact (fixing zone) to a surface area (plate area), effectively changing the dimension of force distribution from 0D to 2D. This dimensional transition disperses the concentrated load across multiple areas of the upright, reducing peak stresses at fixing zones while maintaining reinforcement effectiveness.
Solution Approach 2:
The load distribution plate serves as an intermediary element between the reinforcement element and the upright. Instead of the reinforcement element directly transmitting forces to the upright at fixed points, the plate mediates this force transmission by distributing loads across its surface area, thereby protecting the upright from concentrated stresses.
2Stability of the object's composition
If the upright is straightened by the reinforcement element, then the structural integrity is improved, but the force exerted on upright walls at fixing holes increases causing breakage
Solution Approach 1:
During the straightening process, the load distribution plate converts the concentrated forces generated by upright deformation into distributed surface stresses. This dimensional transformation allows the upright to be straightened effectively while preventing excessive point loads at the fixing holes that would otherwise cause material failure.
3Reliability
If reinforcement element is permanently attached to upright, then the reinforcement durability is improved, but the impact forces are transmitted directly to fixing points causing punctures
Solution Approach 1:
The load distribution plate acts as a protective intermediary between the reinforcement element and the upright during impact events. When impacts occur, the plate absorbs and distributes the shock forces across its surface area, preventing direct transmission of peak impact loads to the fixing holes and reducing the risk of punctures or fastener failure.
Solution Approach 2:
The load distribution plate provides beforehand cushioning by creating a distributed stress field that cushions the upright against future impact forces. This pre-established load path prevents concentrated impact forces from reaching critical fixing points, thereby protecting the permanent attachment system from failure.
