Storage basket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Storage baskets with tapered structures often experience deformation or breakage due to uneven stress on the outer frame, especially when stacked, leading to aesthetic and production quality issues.
Innovation Solution
The design incorporates a side frame with integrated or split-type structures, featuring gaps in the outer frame and corner protectors with bent portions that cover these gaps, along with metal connecting components and various assembly methods like welding and plug-in structures to ensure uniform stress distribution and improved rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the storage basket is made into a tapered structure with an outer frame at the top larger than the bottom, then the stacking function is realized and the supporting role is improved, but the outer frame is unevenly stressed and deforms or breaks easily
Solution Approach 1:
The outer frame is divided into multiple segments with gaps between them, transforming the continuous frame into discrete sections. This segmentation allows the frame to flex and distribute stress more evenly during stacking operations, preventing the concentration of forces that leads to deformation and breakage while maintaining the tapered stacking geometry.
Solution Approach 2:
Corner protectors are added at specific locations where stress concentration occurs most frequently. These localized protective elements reinforce the vulnerable corners and bends of the outer frame, providing targeted strength enhancement exactly where needed during stacking operations, rather than uniformly strengthening the entire frame.
2Strength
If the outer frame is made protruding to play a supporting and reinforcing role, then the structural strength is improved, but the outer frame breaks when the basket is made into the taper
Solution Approach 1:
Corner protectors are pre-installed at the vulnerable bend locations of the outer frame before stacking operations occur. These protectors act as cushioning elements that absorb and distribute the concentrated stresses that would otherwise cause the frame to break, providing preventive protection at the exact locations most susceptible to damage during taper formation and stacking.
Solution Approach 2:
By introducing gaps that segment the outer frame into multiple sections, the structure gains flexibility to accommodate the stress distribution requirements of tapered stacking. This segmentation prevents the continuous frame from becoming a rigid weakness point, allowing the protruding sections to maintain their supporting function while avoiding catastrophic failure.
3Strength
If gaps are formed in all bends of the outer frame, then uniform stress distribution is achieved and deformation is prevented, but the aesthetic appearance is affected
Solution Approach 1:
Corner protectors serve as intermediary elements that fill the gaps created in the outer frame for stress distribution. These protectors visually bridge the segmented sections, concealing the gaps from view while allowing the structural benefits of segmentation to remain. The corner protectors thus mediate between the conflicting requirements of aesthetic appearance and stress distribution, providing both functional and visual continuity.

AI summary
A storage basket, including a side frame and a bottom plate arranged at the bottom of the side frame. The side frame and the bottom plate are of an integrated structure or split-type structures. An outer edge of the top of the side frame is provided with an outer frame; gaps are formed in all bends of the outer frame; corner protectors are wrapped on all the bends of the side frame; and the top of each corner protector has a bent portion that is bent towards the inner side of the side frame or the outer side of the side frame and covers the gap. The outer frame at the top of the storage basket deforms or breaks when the storage basket is made into a taper. The storage basket has high qualification rate, high production efficiency and attractive appearance.
