Pedal Flip-Up Trash Can Linkage for Long-Open Lid Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pedal type trash cans suffer from deformation and quick aging of components due to direct support of the lid by the pedal, requiring continuous pressing for multiple openings, which is inconvenient and reduces the lifespan of the trash can.
Innovation Solution
A pedal type flip-up trash can design with a transmission assembly that controls the lid's rotation via hinge points on the left and right side walls, utilizing a pedal at the front and a transmission rod system to reduce direct pressure on the lid, incorporating a locking mechanism for long-term opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pedal directly supports the lid to open through transmission assembly, then the lid can be opened, but the components will be deformed and aged due to compression after long-time use
Solution Approach 1:
The patent introduces a transmission rod as an intermediary component between the pedal and the lid. The transmission rod transfers the opening force from the pedal to the lid without creating direct compression contact, thereby avoiding deformation and aging of the components while still enabling effective lid opening.
2Stability of the object's composition
If the stainless steel pedal needs to be pressed down continuously to maintain the lid open, then the lid can stay open, but it is inconvenient for repeated operations
Solution Approach 1:
The patent implements a self-locking mechanism where the transmission rod, upon being pushed by the pedal, automatically locks in the open position through its interaction with the transmission block and gear teeth. This eliminates the need for continuous pressing to maintain the lid open, allowing convenient repeated operations while keeping the lid stable in the open state.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design prolongs the service life of the trash can by reducing pressure on components, allows for semi-buried lid opening, and enables convenient, labor-saving operation with long-term lid retention.
Implementation Method 1
a transmission block, which is provided with a plurality of transmission gear teeth and is arranged at the upper end of the transmission rod II; and a transmission gear, which is rotatably arranged in the body assembly, with the side being clamped with one side of the said lid

AI summary
A pedal type flip-up trash can includes a body assembly having an opening; a lid on left and right sides of the opening, wherein a hinge point between the lid and the body assembly is located in a middle rear part of the lid; and a transmission assembly for controlling the opening. The transmission assembly includes a pedal hinged at the bottom of the body assembly; a first rod, movably arranged in a first movable groove at the pedal; a second rod, connected to the first rod through a movable portion, and the first rod is movably arranged in a second movable groove on the movable portion; a block provided with gear teeth and arranged at the second rod; and a gear rotatably arranged in the body assembly, with the side being clamped with the lid, and a clamping point between the gear and the lid is the hinge point.
