Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waste management systems require consumers to manually differentiate domestic waste, leading to inefficiencies and increased costs due to the need for multiple collection containers and an intermediate step of transporting pre-differentiated waste to recycling facilities, which is costly and environmentally impactful.
Innovation Solution
A compact device that automatically treats and separates inorganic solid waste by grinding, sieving, recognizing, and sorting waste fragments into respective bins using a recognition assembly with sensors and a distribution system, allowing for primary differentiation at the point of waste production and reducing the need for intermediate transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If consumers manually differentiate waste into multiple categories, then waste separation is achieved, but the complexity of operation increases and requires multiple collection containers
Solution Approach 1:
The device performs automatic waste differentiation without requiring consumer intervention. Sensors automatically detect and categorize waste materials, and the distribution assembly automatically directs them to appropriate bins, eliminating the need for consumers to manually sort waste into multiple containers.
Solution Approach 2:
Manual mechanical sorting by consumers is replaced with an automated system using sensors (optical, capacitive, inductive), microcontrollers, and automated distribution mechanisms. This substitutes human labor with an automated electromechanical system.
2Productivity
If pre-differentiated waste is transported to recycling facilities, then recycling processing is enabled, but transportation costs and environmental impact increase
Solution Approach 1:
The device performs preliminary waste differentiation and sorting at the point of generation (home or small business), preparing waste for direct recycling processing without requiring intermediate transportation to centralized sorting facilities. This preliminary action eliminates the need for costly transport of pre-differentiated waste.
Solution Approach 2:
The recycling system is segmented into distributed small-scale units at consumption points rather than centralized facilities. Each unit independently handles waste sorting and preparation, enabling local processing and eliminating the need for centralized transportation infrastructure.
3Productivity
If industrial technologies process large volumes of waste, then recycling capacity increases, but the device dimensions and implementation costs increase
Solution Approach 1:
Instead of processing all waste types at high volume through a single large facility, the system performs partial processing at multiple distributed locations. Each device handles a subset of waste streams locally, achieving adequate recycling capacity through aggregated partial actions rather than excessive centralized processing.
Solution Approach 2:
The system transitions from centralized horizontal processing (large facilities handling all waste types) to distributed vertical integration (small devices handling multiple waste types at each location). This dimensional shift allows compact device footprints while maintaining overall processing capacity through networked deployment.
4Loss of time
If manual waste differentiation is performed by consumers, then primary sorting is achieved, but time consumption and labor requirements increase
Solution Approach 1:
Manual consumer labor for waste sorting is replaced with automated sensing and classification systems. Optical sensors, capacitive sensors, and inductive sensors automatically identify waste materials, while a microcontroller directs them to appropriate bins, eliminating time-consuming manual sorting activities.
Solution Approach 2:
The system uses sensor feedback to automatically adjust waste routing decisions in real-time. Sensors continuously monitor waste material properties and provide feedback to the control system, which immediately directs materials to appropriate bins without requiring human decision-making time.

AI summary
The invention relates to a device for the treatment and separation of inorganic solid wastes that can be used, for example, at home and / or near waste disposal areas. The device comprises a grinding chamber for obtaining waste fragments from a group of inorganic wastes and a sieving assembly of the fragments generated in said chamber. The device according to the invention also comprises a recognition assembly for recognizing the type of waste of each individual fragment and a distribution group, operatively interposed between the sieving assembly (6) and the recognition assembly, to place each individual fragment in a corresponding location of analysis of a recognition plate (9) of the recognition group. The device according to the invention is further provided with a monitoring and drive unit (200) configured to act on the recognition plate (9) so as to deposit each single analyzed waste fragment in a respective collection bin (13).
