Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current household garbage systems require manual handling and frequent replacement of garbage bags, leading to poor user experience and environmental pollution due to low waste density.
Innovation Solution
A storage device with a barrel-shaped body, storage bag convey member, and a first driving part comprising a rotation part and rocker arm, which automatically opens and tightens storage bags by conveying them to the side edge of the barrel-shaped body, allowing for convenient automatic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling of garbage bags is used, then device complexity is reduced, but ease of operation deteriorates due to frequent manual replacement
Solution Approach 1:
The garbage can system performs automatic bag replacement without user intervention. The controller automatically detects when a bag is full, opens the lid, removes the full bag, and installs a new bag, enabling the system to serve itself and eliminate manual handling
Solution Approach 2:
The system prepares for bag replacement in advance by monitoring waste accumulation levels. When the bag approaches full capacity, the system proactively initiates the replacement sequence before complete fullness occurs, ensuring smooth operation without user intervention
2Productivity
If manual removal of full garbage bags is required, then device complexity is reduced, but productivity deteriorates due to frequent intervention
Solution Approach 1:
The automatic bag replacement system eliminates the need for user intervention in bag removal and installation. The controller autonomously manages the entire replacement process, significantly improving productivity by freeing users from this repetitive task
Solution Approach 2:
The system uses sensors to continuously monitor waste accumulation and provides feedback to the controller. This feedback mechanism enables the system to automatically determine when bag replacement is needed and execute the replacement sequence at optimal intervals, maximizing productivity
3Quantity of substance
If garbage bags are replaced frequently due to low waste density, then storage capacity is effectively utilized, but loss of substance increases due to wasting garbage bags
Solution Approach 1:
The weighing sensor continuously measures waste mass and provides feedback to the controller. This enables the system to track actual waste accumulation and determine the optimal moment for bag replacement, ensuring bags are used to full capacity and reducing premature replacement
Solution Approach 2:
The system monitors waste density and accumulation in real-time, preparing for bag replacement only when actually needed. This preliminary monitoring prevents premature replacement and ensures maximum utilization of each garbage bag's capacity
4Ease of operation
If automatic bag opening and tightening is implemented, then ease of operation is improved, but device complexity increases due to additional mechanisms
Solution Approach 1:
The bag opening and tightening functions are integrated into the same mechanical mechanism. The first driving part performs both operations sequentially using a unified structure, reducing overall system complexity compared to having separate mechanisms for each function
Solution Approach 2:
The first driving part serves multiple functions: it opens the bag by pulling the sealing portion and later tightens the bag after replacement. This multi-functional component reduces the need for separate dedicated mechanisms, managing complexity while providing comprehensive automation

Function Achieved in This Case
The solution improves user satisfaction by automating the opening and tightening of storage bags, reducing the need for frequent replacements and minimizing environmental impact by maintaining waste density.
Implementation Method 1
the rocker arm is configured to rotate along the side wall under drive of the rotation part, so that an end of the storage bag is dragged to move along the side edge of the side wall away from the bottom board
