Sweeper Bin with Rotatable Magnet for Safe Ferrous Debris Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sweeper bins are inadequate for safely collecting ferrous materials such as nails, screws, and metal shavings in environments like construction sites and warehouses, as they can pose safety hazards when left uncontained on the ground.
Innovation Solution
A sweeper system comprising a magnet with a rotatable separator plate, wheels, a shaft, a lever, a hanger, and a receptacle system with a bin and insert, allowing for selective pickup and containment of ferrous items, which includes a mechanism to rotate the magnet away from the plate to release items into a bin, ensuring safe collection and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ferrous materials are left on the ground for collection, then the sweeper bin can collect items, but safety hazards increase due to uncontained ferrous items
Solution Approach 1:
The magnet is made rotatable relative to the separator plate, allowing dynamic adjustment between pickup mode (magnet facing plate) and release mode (magnet rotated away). This dynamic mechanism enables continuous operation without manual intervention, resolving the contradiction by automatically containing items while maintaining safety.
Solution Approach 2:
The separator plate acts as an intermediary between the magnet and the external environment. It allows ferrous items to be picked up from the ground while preventing them from contacting the magnet directly during transport, thus containing items safely without requiring the magnet itself to be exposed.
2Productivity
If the magnet continuously picks up items, then collection efficiency increases, but items cannot be released into the bin
Solution Approach 1:
The rotatable magnet mechanism allows the system to switch between pickup and release modes. During pickup, the magnet faces the separator plate to attract items; during release, the magnet rotates away to deposit items into the bin. This dynamic adjustment maintains high productivity while enabling easy operation.
Solution Approach 2:
The magnet undergoes periodic rotation between pickup and release positions, creating a cyclic operation that continuously collects and releases items. This periodic action ensures both high collection efficiency and smooth item transfer to the bin without manual intervention.
3Ease of manufacture
If the sweeper bin structure is simple, then manufacturing cost decreases, but containment reliability during transport is insufficient
Solution Approach 1:
The sweeper bin is segmented into distinct functional components: the bin body for containment, the separator plate for item separation, and the rotatable magnet mechanism for pickup and release. This segmentation allows each component to be manufactured independently and assembled, maintaining cost-effectiveness while improving containment reliability through specialized design of each segment.
Solution Approach 2:
The separator plate is positioned within the bin structure, and the rotatable magnet mechanism is integrated into the bin assembly. This nested arrangement maximizes containment reliability by ensuring items are separated and contained within the bin volume, while the compact integrated design keeps manufacturing complexity and cost manageable.
4Productivity
If ferrous items are collected in large quantities, then cleaning effectiveness increases, but transport and storage become problematic
Solution Approach 1:
The rotatable magnet mechanism enables easy discharge of collected items by rotating the magnet away from the separator plate, allowing accumulated ferrous items to be released into the bin. This dynamic release capability solves the transport and storage problem by providing a simple, automated discharge mechanism that maintains cleaning effectiveness without creating handling difficulties.

AI summary
A receptacle system for a sweeper that includes a bin with a base and sidewalls that together define a receptacle space that receives items released from the sweeper, an insert attached to the bin where an upper portion of the insert slopes upward from a front side towards a rear side of the receptacle system when the insert is attached to the bin with tracks defined in the upper portion for the wheels of the sweeper to roll along the slope to position the sweeper above the bin, and where the insert covers a portion of the receptacle space, where the insert defines an opening such that items released by the sweeper pass through the opening when the wheels of the sweeper are positioned on the tracks of the insert.
