Stacking Basket Connection Clips for Stable Vending Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sales devices with stacking and/or attachment baskets lack a secure connection system, leading to instability and safety risks due to toppling stacks, complex and costly fixed connections, and cumbersome handling, which fails to meet increasing product safety requirements.
Innovation Solution
A connection system utilizing screw-in and push-in tabs, stationary on a holder, providing a stable and non-movable unit without the need for additional connecting elements, ensuring easy assembly and secure stacking of baskets of varying sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If stacking baskets are connected using sheet metal profiles, brackets, or wire loops, then assembly is simple and flexible, but the connection stability is insufficient and toppling risk increases
Solution Approach 1:
The connection system is divided into separate functional elements: push-in tabs for initial positioning and screw-in tabs for secure locking. This segmentation allows each element to perform its specific function optimally while maintaining overall system simplicity and reliability.
Solution Approach 2:
The push-in tabs are designed to be inserted first to preliminarily position and align the baskets, preparing the connection interface before the screw-in tabs are engaged for final secure locking. This preliminary action simplifies the overall assembly process while ensuring stable connection.
2Reliability
If fixed systems use force-locking connection methods, then connection stability is improved, but device complexity and capital investment increase
Solution Approach 1:
The connection system is designed to be self-contained with all necessary connecting elements (push-in tabs and screw-in tabs) integrated into the basket structure itself. No external tools or additional connecting elements are required, eliminating the need for complex fixed systems while maintaining connection stability.
Solution Approach 2:
The push-in and screw-in tab elements are combined with the basket holder as integrated components rather than separate external connectors. This merging reduces system complexity by eliminating the need for additional connecting elements while providing reliable force-locking connection.
3Reliability
If additional connecting elements are used to secure baskets, then connection reliability is improved, but manufacturing cost and assembly complexity increase
Solution Approach 1:
The push-in tabs and screw-in tabs are merged with the basket holder as integrated components, eliminating the need for additional separate connecting elements. This reduces manufacturing cost by reducing part count while maintaining stacking security through the combined functionality of the integrated tabs.

AI summary
The machine (1) has a table (2), and two cages (1a) and/or chutes that are stacked one above the other. The cages are connected with each other using a connection system in a tiltable or movable manner. The connection system is formed from a rotating clip and an insertion clip. Each cage and/or chute is provided with a retainer, where the rotating clip and the insertion clip are fixedly arranged at the retainer.
