Shredding Machine With Rotating Bin for Even Material Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shredders often experience premature stoppages due to uneven distribution of shredded material, requiring frequent manual intervention to redistribute or empty the collection bin, and lack visibility into the filling level, limiting their operational efficiency and capacity.
Innovation Solution
A shredding machine with a rotating collection bin and offset cutters, combined with a transparent door providing extensive viewing and interior lighting, ensures even distribution of shredded material and accurate bin filling detection, enhancing operational efficiency and capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional shredders use a stationary collection bin, then the structure is simple, but the shredded material accumulates unevenly causing premature stoppages and requiring frequent manual intervention
Solution Approach 1:
The collection bin is transformed from a stationary structure to a rotating one, allowing it to dynamically redistribute shredded material during operation. The bin rotates about a vertical axis during shredding cycles, enabling material to be evenly distributed across the entire bin volume rather than accumulating in one location, thereby preventing premature stoppages and extending operational capacity.
2Ease of operation
If conventional shredders use opaque collection bins, then manufacturing is simpler, but users cannot see the filling level requiring manual checking and intervention
Solution Approach 1:
The collection bin is made transparent or translucent, allowing visual detection of the filling level without opening the door. This optical property change enables users to monitor material accumulation in real-time, determine when the bin needs emptying, and plan operations accordingly, eliminating the need for manual door opening and direct inspection.
3Ease of operation
If conventional shredders lack interior lighting, then energy consumption is lower, but users cannot detect shredded material falling into the bin
Solution Approach 1:
The interior lighting system operates periodically rather than continuously - activating during shredding cycles when material is being processed and deactivating during idle periods. This intermittent operation provides necessary visual feedback about material accumulation and falling shredded material while minimizing energy consumption during non-operational times.

AI summary
A shredding machine includes an outer housing including a main portion and a door. The outer housing defines an interior space. A shredding engine positioned above the interior space includes a shredding motor and a plurality of interleaved cutters. A material passage is configured to receive material to be shredded and direct the material to be shredded to the plurality of interleaved cutters. A collection bin is constructed of transparent material and removably received inside the interior space, the collection bin being open at a top end and defining a central vertical axis. An interior lighting element is operable to emit light in the visible spectrum into the collection bin. During operation of the shredding engine, the collection bin is configured to rotate within the outer housing about the central vertical axis and the interior lighting element is energized to illuminate shredded material as it falls into the collection bin.
