Solution Overview
Problem
Current solid urban waste collection systems face issues such as lack of proper differentiation, identification of depositors, accurate weighing, and efficient monitoring, leading to inefficient waste management and high costs without collective benefits.
Innovation Solution
An apparatus using 'smart' skips with electronic identification keys, biodegradable bags, and sensors for precise waste type and weight determination, along with automatic sorting and real-time data management via cloud technology, ensures correct deposition, monitoring, and optimized collection routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional bins or skips are used for waste collection, then the system is simple and easy to operate, but the waste cannot be properly differentiated and monitored
Solution Approach 1:
The waste collection system is segmented into multiple specialized containers (organic waste container, recyclable waste container, residual waste container) instead of using a single general-purpose bin. Each container is equipped with specific identification and monitoring features tailored to the type of waste it collects, enabling proper differentiation while maintaining operational simplicity through clear visual and digital标识
Solution Approach 2:
The system incorporates feedback mechanisms including weight sensors that monitor waste deposition, electronic identification keys that track user contributions, and cloud-based platforms that provide real-time data to municipal authorities. This feedback loop ensures accurate waste differentiation and enables monitoring without significantly increasing operational complexity
2Measurement precision
If magnetic card access systems are used for skip control, then depositor identification is enabled, but operator judgement remains subjective and conflicts arise
Solution Approach 1:
The system replaces subjective operator judgement with automated electronic verification. Electronic identification keys paired with magnetic card access create an objective digital record of depositor identity and waste type selection. Weight sensors and container identification systems automatically verify waste classification, eliminating human bias and conflicts while maintaining precise depositor identification
Solution Approach 2:
An automated control system acts as an intermediary between the depositor and the waste collection process. The system mediates waste type verification through electronic records and sensor data rather than direct human inspection, providing reliable and consistent waste classification without operator involvement in the verification process
3Reliability
If door-to-door collection with multiple containers is provided, then waste differentiation is improved, but storage burden and collection costs increase
Solution Approach 1:
The system merges multiple waste separation functions into a single integrated smart container unit. Users deposit all differentiated waste types into one container with internal compartments or designated sections for different waste categories. The container is equipped with sensors and identification systems that automatically track and verify the separation quality, maintaining high waste separation standards while simplifying user storage requirements
Solution Approach 2:
The smart container serves multiple functions: it stores different waste types, identifies waste categories through sensors, tracks depositor information, communicates with the central management system, and provides user interface for waste deposition. This multi-functionality reduces the number of separate containers users need to manage while maintaining reliable waste separation
4Productivity
If waste skips are equipped with load cells for weight monitoring, then collection scheduling is optimized, but density variations make weight-to-volume conversion approximate
Solution Approach 1:
The system creates a digital copy or model of the waste characteristics by combining weight sensor data with waste type identification. Different density values are assigned to different waste categories (organic, recyclable, residual) based on their known physical properties. This digital representation allows accurate volume estimation from weight measurements by applying type-specific conversion factors, maintaining collection scheduling efficiency while improving volume estimation precision

AI summary
The apparatus comprises a container (100), namely a skip for collecting solid urban waste, positioned upstream of the apparatus, provided with: - identification key means assigned to an individual user authorised to deposit, - closure means (101), - means for controlling opening of the closure means, - a control unit linked to locking and unlocking means for said closure means, - means (114) for containing and identifying a bag (130) containing inside it waste to be differentiated. The apparatus is further provided with means (113, 117, 118) which slide on motorised rack means (150), for containing, transporting and releasing a bag (130) containing the differentiated waste into at least one of containers (200, 300, 400, 500, 600, 700), namely skips for collecting bags of waste, arranged along the line of operation of the apparatus. All of skips (100, 200, 300, 400, 500, 600, 700) are inserted in series into a structure (160) anchored to the ground and capable of ensuring the precise positioning and protection thereof.
