Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smart trash receptacles lack the capability for automatic and reliable trash bag fitting, leading to inconsistent bag placement and potential breakage during replacement, and they are unable to detect the position of the trash bag within the receptacle, limiting their intelligence and safety.
Innovation Solution
A smart trash receptacle equipped with a trash bag fitting device featuring a vacuum assembly driven by a motor and a trash bag detection device using a transmitter-receiver pair with a control mechanism, which ensures automatic and precise bag fitting by detecting the bag's presence and position, preventing breakage and enhancing operational reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual or semi-automatic bag replacement is used, then device complexity is reduced, but bag fitting quality and reliability deteriorate due to inconsistent manual operation and degraded adhesive effectiveness
Solution Approach 1:
The patent replaces manual mechanical operations with an automated mechanical system comprising a linkage mechanism, adhesive application device, and bag positioning mechanism. This substitution eliminates the inconsistency of manual operation while maintaining reasonable device complexity through integrated control
Solution Approach 2:
The system enables self-service automatic bag replacement by detecting when the bag is full and automatically executing the replacement sequence without human intervention, including opening the new bag, applying adhesive, positioning it on the receptacle, and sealing it
2Productivity
If automatic bag replacement is implemented without detection capability, then productivity is improved, but reliability deteriorates due to inability to detect bag position and prevent breakage
Solution Approach 1:
The patent incorporates a detection device that provides real-time feedback on bag position and filling status. This feedback mechanism allows the control system to monitor the replacement process, detect when the bag is properly positioned, and prevent operations that would cause breakage, thereby ensuring reliability while maintaining high productivity
Solution Approach 2:
The system performs preliminary detection of bag position and status before executing replacement operations. By detecting the presence and position of the bag in advance, the system can prepare appropriate actions and prevent breakage before it occurs
3Ease of operation
If adhesive substance is used for semi-automatic bag opening, then ease of operation is improved, but reliability worsens due to degraded adhesiveness over time
Solution Approach 1:
The patent replaces reliance on adhesive substances with a mechanical linkage mechanism that physically opens and secures the bag. This mechanical approach eliminates the problem of degraded adhesiveness while maintaining ease of operation through automated actuation
Solution Approach 2:
The system automatically applies fresh adhesive or activates mechanical opening mechanisms as needed during each replacement cycle, ensuring consistent effectiveness without manual intervention to replace degraded adhesive
