Refuse Container Lid Opener Using Face-Mounted Cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lid opening devices for waste containers, particularly those with tie rods connecting the pedal to the cover, suffer from clutter in handling areas, exposure to damage, and loss of storage volume due to the placement of tie rods on lateral faces and the need for additional protection mechanisms.
Innovation Solution
A lid opening device using a force transmission cable arranged on the same face as the pedal, allowing for flexible placement without obstructing the container's volume and reducing clutter, with optional features like actuation bars and connecting members to enhance functionality and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tie rods are placed on lateral faces of the container to transmit force from the pedal to the lid, then the lid opening function is achieved, but the lateral faces become cluttered and interfere with emptying hatch operations
Solution Approach 1:
The force transmission element is moved from the lateral dimension (side faces) to the vertical dimension (same face as pedal), eliminating interference with lateral emptying operations while maintaining force transmission functionality
2Reliability
If tie rods are placed outside the container to protect them from damage, then they are protected against impacts, but they occupy external space and require additional protection devices
Solution Approach 1:
The force transmission element is integrated within the container structure itself, merging the function of force transmission with the container body, thereby eliminating the need for separate external protection devices
3Reliability
If tie rods are placed inside the container to protect them from damage, then they are protected against impacts, but waste blocks their movement
Solution Approach 1:
The force transmission path is routed along the external surface of the container rather than through the internal waste volume, allowing the element to remain protected while maintaining unobstructed movement capability
4Reliability
If tie rods are placed inside the container, then they are protected from external impacts, but waste storage volume is reduced
Solution Approach 1:
The force transmission element is extracted from the internal waste storage space and positioned on the external surface of the container, thereby preserving the full waste storage volume while maintaining structural protection
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 a more compact, less prone to damage, and efficient lid opening mechanism that maintains waste storage volume by using a flexible cable for force transmission, allowing for easier installation and operation while avoiding blockages and damage.
Implementation Method 1
at least one force transmission cable connecting the lid opening pedal to the lid, the lid opening device being configured so that actuation of the lid opening pedal causes the lid to open by pulling the force transmission cable on the lid
