Pedal Bin Baffle Plate Linkage for Odor Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pedal bins disperse unpleasant odors when the lid is opened for waste disposal, causing user discomfort.
Innovation Solution
A pedal bin with a linkage mechanism and baffle plates that automatically seal the garbage bag opening when the lid is opened, using toggle blocks and restoring members to control the baffle plates' movement, preventing odor dispersion and allowing easy garbage bag replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid is opened for waste disposal, then waste can be thrown into the bin, but unpleasant odor disperses causing user discomfort
Solution Approach 1:
The invention divides the opening mechanism into two independent parts: the lid for waste disposal and the baffle plate for odor sealing. The baffle plate can be independently controlled to remain closed while the lid is opened, segmenting the functions of waste access and odor containment to resolve the contradiction between ease of operation and odor prevention.
Solution Approach 2:
The baffle plate acts as an intermediary element between the garbage bag and the external environment. It selectively controls odor dispersion while allowing waste to be disposed of through the lid, serving as a mediator that separates the function of waste access from odor containment.
2Object-affected harmful factors
If the baffle plate is kept closed to prevent odor, then odor dispersion is prevented, but waste cannot be disposed of
Solution Approach 1:
The system segments the waste disposal path into two routes: waste can be disposed of either by opening the lid or by opening the baffle plate. This segmentation allows the baffle plate to remain closed for odor containment while providing an alternative waste disposal route through the lid, resolving the contradiction between odor containment and waste disposal ability.
Solution Approach 2:
The lid serves multiple functions: it allows waste disposal when opened and maintains odor containment when closed. The baffle plate similarly provides both odor sealing and waste access functions. This multi-functionality resolves the contradiction by allowing either component to handle waste disposal while the other maintains odor containment.
3Extent of automation
If the linkage mechanism is added to control baffle plate, then automatic sealing is achieved, but device complexity increases
Solution Approach 1:
The linkage mechanism uses dynamic toggle blocks that can automatically switch between locked and unlocked states based on pedal pressure. This dynamic behavior achieves automatic sealing without requiring complex control systems, resolving the contradiction between automation extent and device complexity by using simple mechanical dynamics.
Solution Approach 2:
The toggle blocks in the linkage mechanism are self-actuating components that automatically engage or disengage based on the mechanical state of the pedal and connecting rods. The system serves itself through mechanical feedback without external control, achieving automatic sealing with minimal complexity.

Function Achieved in This Case
Prevents odor dispersion by automatically sealing the garbage bag opening during use and facilitates easy garbage bag replacement.
Implementation Method 1
an elastic member is arranged in the blind hole, and a top of the elastic member is pressed against the bottom of the base
Implementation Method 2
the first restoring member is connected to the toggle block and the first connecting rod, after the toggle block is moved upward and separated from the linkage mechanism, the toggle block is reset by the first restoring member
Implementation Method 3
the second restoring member is connected to one of the toggle rods and the positioning shell, after the toggle blocks are moved downward and separated from the stop block, the toggle rods are reset by the second restoring member
