Solution Overview

Problem

Existing shredders and balers are limited in their ability to handle multiple types of materials, particularly non-fibrous materials, and require complex designs that increase costs and are often suited for small-scale operations, making it difficult to efficiently shred and bale materials like wood, metal, and demolition debris without the need for separation or sorting.

Innovation Solution

A mobile, industrial-sized shredder-baler apparatus with a conveyor system that uses a rotatable drum with spirally arranged cutting teeth and a baler with flexible bands and rollers to shred and compact materials into bales, allowing for the simultaneous processing of various materials without the need for sorting, and equipped with a wrap feeder to secure the bales for transport and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a shredder is designed to handle a specific type of material, then the shredding efficiency for that material is improved, but the adaptability to handle multiple types of materials deteriorates

Engineering Contradiction:
Improveshredding efficiencyVSAvoidmaterial type adaptability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The shredder is designed with universal cutting mechanisms and adjustable settings that enable it to efficiently process multiple types of materials including wood, metal, plastic, and demolition debris without requiring separate specialized equipment for each material type

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Manufacturing precision

If multiple rotating cutting mechanisms and screening apparatus are used, then the shredding completeness is improved, but the device complexity increases

Engineering Contradiction:
Improveshredding completenessVSAvoidshredding mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Multiple cutting mechanisms and screening functions are merged into a single integrated shredding chamber where debris undergoes multiple cutting passes and screening stages within one continuous process flow, reducing the number of separate mechanisms while maintaining shredding completeness

Inventive Principle:
Principle #5Merging (Combining)

3Volume of stationary object

If material is shredded into smaller pieces, then the space occupation is reduced, but the collection and containment difficulty increases

Engineering Contradiction:
Improvespace occupationVSAvoidcollection and containment ease
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

A conveyor system acts as an intermediary mechanism that automatically collects and transports the shredded debris from the shredding chamber to a collection receptacle, eliminating the manual collection difficulty while maintaining the space reduction benefits of shredding

Inventive Principle:
Principle #24Intermediary (Mediator)

4Volume of stationary object

If a baler is used to compress non-fibrous materials like dirt and mulch, then the volume reduction is improved, but the bale integrity deteriorates

Engineering Contradiction:
Improvevolume reductionVSAvoidbale integrity
Core Design Contradiction:
Volume of stationary objectVSStability of the object's composition

Solution Approach 1:

The baler employs adjustable compression parameters including variable compression forces, controlled compression rates, and adjustable bale density settings that can be optimized for different material types including non-fibrous materials, maintaining bale integrity while achieving volume reduction

Inventive Principle:
Principle #35Parameter changes

5Reliability

If traditional shredders and balers are used separately, then the specialization for specific tasks is improved, but the overall processing efficiency deteriorates

Engineering Contradiction:
Improvetask specializationVSAvoidoverall processing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The shredder and baler are merged into a single integrated apparatus where the shredding chamber is directly coupled with the baling mechanism, allowing material to be shredded and compressed in one continuous operation without transfer or intermediate handling, improving overall processing efficiency while maintaining task specialization

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A shredding and baling apparatus provided includes a shredding assembly operatively connected to a baling assembly via a conveyor. A rotatable drum with cutting teeth spirally arranged along the drum is preferably centered within a lower portion of an intake hopper for cutting through material as it is fed into the hopper. Fixed cutting teeth are preferably arranged in a row or rows along each of the longitudinal sidewalls of the hopper, adjacent the cutting drum. A touch screen display and computer may be used in combination with sensors to monitor and control the shredding and baling operation, and a hydraulic system is used to drive the components. The shredding and baling assembly is preferably designed in an industrial size to handle high volumes of material and may be driven or transported from one location to another.
