Basket Side Frame Clamping Structure for Stronger Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional basket structures require additional processing steps and have insufficient connecting strength due to linear contact between clamping units, leading to increased manufacturing costs and reduced structural integrity.
Innovation Solution
A basket design featuring a rhombic mesh main body with a connecting edge and a side frame that surrounds and clamps the edge using a first and second side, eliminating the need for bending and enhancing contact areas for improved strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wing portion is bent to connect with the frame unit, then the basket can be assembled, but an additional processing step is required increasing manufacturing complexity
Solution Approach 1:
The connecting edge is pre-formed as a straight edge during the main body fabrication process, eliminating the need for subsequent bending operations. The side frame is designed with pre-positioned clamping surfaces that directly engage the connecting edge, so no additional forming steps are required during assembly.
Solution Approach 2:
The bending operation is completely removed from the manufacturing process. Instead of bending the wing portion, the design extracts the connection function to a dedicated side frame component that clamps onto the straight connecting edge, separating the main body fabrication from the connection process.
2Strength
If the circular units clamp the wing portion through the periphery, then connection is achieved, but the contact area is merely linear resulting in insufficient connecting strength
Solution Approach 1:
The connection interface transitions from linear contact (1D) to areal contact (2D). The side frame's clamping surfaces engage the connecting edge across a two-dimensional area, with the inner surface contacting one face and the outer surface contacting the opposite face, creating substantial contact area for enhanced connection strength.
Solution Approach 2:
The side frame is designed with localized clamping surfaces that concentrate the connection function at specific high-strength contact zones. The inner and outer surfaces of the side frame provide locally optimized contact areas that maximize connecting strength at the critical interface with the connecting edge.

AI summary
A basket may include a main body and a side frame. The side frame surrounds at the portion of a connecting edge, and a first side and second side clamps with each other by applying a pressure on the side frame, so the first side clamps at an inner portion of the connecting edge and the second side clamps at an outer portion thereof. Thus, the side frame can be quickly connected with the main body without bending the connecting edge to a predetermined angle, which can simplify the assembly process and further reduce the production costs.
