Shoe Cover Cartridge Dispensing via Interlocking Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic shoe cover dispensers are complex to install and require electrical power, with shoe covers needing to be attached individually, making them unsuitable for mass production and inconvenient to use.
Innovation Solution
An automatic shoe cover dispenser with a replaceable shoe cover cartridge that uses overlapping shoe covers with interlocking units and guiding arms to dispense shoe covers sequentially without the need for motorized devices or electrical power, simplifying installation and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If shoe covers are affixed one-by-one in a dispensing mechanism, then the shoe covers can be dispensed sequentially, but the production process becomes complicated and installation becomes inconvenient
Solution Approach 1:
The invention divides the shoe cover storage into modular cartridges, each containing multiple shoe covers stacked together. This segmentation allows the complex dispensing mechanism to be replaced with simple cartridge insertion, making installation convenient while maintaining sequential dispensing capability.
Solution Approach 2:
The invention extracts the complicated affixing and dispensing mechanism and replaces it with a simple cartridge-based system. The shoe covers are pre-packaged in cartridges that are simply inserted into the dispenser, eliminating the need for complex one-by-one attachment mechanisms.
2Extent of automation
If a motorized device is used to dispense shoe covers, then the shoe covers can be dispensed automatically, but electrical power is required and increases device complexity
Solution Approach 1:
The shoe cover cartridge is designed to be self-sufficient, containing all necessary components for automatic dispensing without requiring external power. The cartridge structure itself enables the shoe covers to be dispensed automatically through simple mechanical interaction when pulled from the dispenser.
Solution Approach 2:
The invention replaces motorized electrical systems with a purely mechanical cartridge-based dispensing system. The automatic dispensing function is achieved through mechanical means - simply pulling the cartridge triggers the sequential release of shoe covers without requiring any electrical power or complex motorized mechanisms.
3Productivity
If shoe covers are stacked individually, then they can be dispensed one-by-one, but the installation process becomes complicated
Solution Approach 1:
The invention merges multiple individual shoe covers into a single integrated cartridge unit. Instead of installing each shoe cover separately, multiple covers are pre-assembled in the cartridge during manufacturing, allowing rapid installation by simply inserting the entire cartridge into the dispenser while maintaining sequential dispensing capability.

AI summary
A shoe cover cartridge includes two guiding arms and a plurality of shoe covers overlapped in a sequential manner to define a standby shoe cover and a subsequent shoe cover. Front and rear interlocking units are provided at front and rear sides of each of the shoe cover respectively and are slidably engaged with the guiding arms at a position that the front interlocking unit at the subsequent shoe cover is located in front of the rear interlocking unit at the standby shoe cover along the guiding arms. Therefore, when the standby shoe cover is pulled for dispensing, the subsequent shoe cover is pulled by the standby shoe to dispense the shoe covers in a sequential order.
