Pedal-Actuated Trash Can With Damping and Stabilizing Protector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trashcans lack features for stabilization, easy stacking, and efficient bag insertion and separation, which affects their usability and storage efficiency.
Innovation Solution
Incorporating a pivotable pedal protector for stabilization, notches on the body for bag insertion, and dividers to separate trash bags, along with a damping mechanism to slow lid closure and a lid actuating system with a pedal linkage, enhancing the trashcan's functionality and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pedal actuating system is added to enable foot operation, then ease of operation is improved, but device complexity increases
Solution Approach 1:
A pedal actuating system with linkage mechanism is introduced as an intermediary between the user's foot and the lid, enabling foot operation without requiring direct manual handling of the lid. The pedal serves as a mediator that converts foot pressure into lid opening motion.
Solution Approach 2:
The manual hand-operated lid opening mechanism is replaced with a foot-operated pedal system. This substitution allows users to operate the trashcan with their foot, improving ease of operation particularly when hands are occupied or hygiene is a concern.
2Object-affected harmful factors
If a damping mechanism is added to slow lid closure, then harmful factors are reduced (noise prevention), but device complexity increases
Solution Approach 1:
A damping mechanism is incorporated into the lid assembly to provide cushioning during the closing motion. This mechanism slows down the lid as it approaches the closed position, preventing loud slamming noises and potential damage to the lid or receptacle body.
Solution Approach 2:
The potential harm of loud slamming noise and impact damage is converted into a beneficial slow, controlled closing motion. The damping mechanism transforms the harmful rapid closure into a gentle, noise-free closing action.
3Reliability
If a lid latch is added to lock the lid in closed position, then reliability is improved, but device complexity increases
Solution Approach 1:
The lid latch is designed to automatically engage when the lid is closed, providing self-service functionality. The latch mechanism self-activates through the natural closing motion of the lid, eliminating the need for separate manual locking actions while ensuring reliable closure.
Solution Approach 2:
Manual lid securing is replaced with an automatic mechanical latch system. The latch uses the lid's own closing motion to trigger engagement, providing reliable locking without requiring additional manual steps or complex control systems.
4Stability of the object's composition
If a pedal protector is added to prevent tipping, then stability is improved, but device complexity increases
Solution Approach 1:
A pedal protector is introduced as a stabilizing element that prevents the pedal from causing the trashcan to tip over. This protector acts as an intermediary between the pedal mechanism and the ground, providing structural support and preventing instability.
Solution Approach 2:
The pedal protector is designed to prevent tipping before it occurs by providing a stable base and limiting the pedal's range of motion. This preventive measure ensures stability during operation without requiring corrective actions after tipping begins.
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 solution provides stability, facilitates easy stacking and bag separation, reduces noise during lid closure, and improves the overall usability and storage efficiency of trashcans.
Implementation Method 1
a damping mechanism connected to the mounting platform and to at least one of the linkages and pedal, the damping mechanism configured to dampen movement of the lid in at least one of an opening and closing motion

AI summary
A trashcan with a lid can include a pedal bar and a pedal protector. The pedal protector can be flipped and/or rotated, such that the pedal protector can be moved adjacent the pedal (e.g. below the pedal) or away from the pedal bar. The trashcan with a lid can further include at least one notch and/or divider to allow for insertion of more than one trash bag into the body of the trashcan.
