Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accumulation of garbage in bins leads to mold and odor production, affecting human health and environmental pollution due to forgotten garbage bags, which existing solutions fail to address effectively.
Innovation Solution
A method and device that acquire garbage information and spoiling feature information using mobile terminals, determining mold or odor presence, and sending user prompts to change the garbage bag, incorporating barcode scanning, camera identification, spectroscopic analysis, and smell sensors, with additional checks for user behavior and proximity to reduce false alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple detection methods (barcode scanning, camera identification, spectroscopic analysis, smell sensors) are used to accurately determine garbage spoiling, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The detection system is divided into multiple independent modules: barcode scanning module, camera identification module, spectroscopic analysis module, and smell sensor module. Each module independently detects different aspects of garbage characteristics, and their results are integrated to achieve comprehensive and accurate spoiling determination without requiring one complex all-in-one system
Solution Approach 2:
The mobile terminal is designed to perform multiple functions: it serves as both the detection device and the processing/communication device. The same mobile terminal can scan barcodes, capture images for camera identification, perform spectroscopic analysis, and receive signals from smell sensors, eliminating the need for separate dedicated detection hardware and reducing overall system complexity
2Reliability
If user behavior information and distance checks are added before sending alerts, then false alerts are reduced, but processing time increases
Solution Approach 1:
User behavior information and distance data are collected and stored in advance before the actual spoiling detection is performed. When garbage spoiling is detected, the system can immediately compare against pre-collected user context information without needing to query or process additional data at the moment of alert generation, significantly reducing processing delay
Solution Approach 2:
The system continuously monitors user behavior patterns and uses this feedback to refine alert generation. By analyzing historical user behavior data, the system learns when alerts are likely to be false positives and adjusts its decision-making accordingly, improving reliability without requiring complex real-time analysis that would increase processing time
