Garbage Can Lid Assembly with Static Electricity Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garbage cans require direct contact or continuous power supply to operate, which can lead to germ transmission and inefficiency in user interaction.
Innovation Solution
A garbage can lid assembly equipped with a static electricity sensor that automatically opens and closes the lid based on detected static electricity from a user's body, eliminating the need for direct contact and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a garbage can uses contact-based operation (pedal or manual opening), then it is simple in design and easy to manufacture, but it transmits germs to the user
Solution Approach 1:
The patent replaces the mechanical contact-based opening system (pedal or manual) with an electrostatic sensing system. The sensor detects static electricity on the user's body through non-contact means, triggering the lid opening mechanism without requiring physical contact between the user and the garbage can, thereby eliminating germ transmission while using a relatively simple sensing component
Solution Approach 2:
The patent introduces static electricity as an intermediary medium between the user and the garbage can lid. Instead of direct mechanical contact, the user's static electric field serves as the trigger signal for lid opening, allowing the system to respond to user presence without physical contact and thus preventing germ transmission
2Ease of operation
If a garbage can uses infrared sensor to detect user presence, then it enables hands-free operation, but it requires continuous power supply that drains battery constantly
Solution Approach 1:
The patent employs periodic or event-triggered sensing rather than continuous monitoring. The electrostatic sensor only activates when a user with static electricity approaches, rather than continuously scanning for presence. This event-driven operation significantly reduces power consumption compared to continuous infrared monitoring while still enabling hands-free operation
Solution Approach 2:
The patent changes the detection parameter from optical (infrared) to electrostatic field detection. Electrostatic sensors can detect the presence of charged objects (users) without requiring continuous power for active emission like infrared sensors do. This parameter change allows the system to maintain hands-free operation capability while dramatically reducing energy consumption
3Object-affected harmful factors
If a garbage can uses electrostatic sensor for automatic opening, then it reduces germ transmission and power consumption, but it requires detection of specific physical property (static electricity)
Solution Approach 1:
The patent leverages the user's own static electricity, which naturally accumulates on the body through everyday movement and clothing friction, as the detection signal. The system doesn't require additional equipment to generate or modify this property - it simply detects the naturally occurring static charge on users, making the detection process straightforward and self-service

AI summary
A lid assembly for use with a garbage can having a frame that includes a lip at the bottom of lid and a housing. The housing is defined by a lower wall and a sidewall with an opening. A static electricity sensor is positioned in the housing. The lid assembly also includes a displaceable door that moves with the lip to open the garbage can. So that when the static electricity sensor detects the static electricity of a user, the displaceable door slides to open the garbage can and when the static electricity sensor does not detects the static electricity of a user, the displaceable door slides to close the garbage can.
