Waste Container Locking Device Pendulum Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste container locking devices fail to prevent unintended opening due to accidental knocks or tilting, which can lead to spillage or animal access, while also requiring manual unlocking for automated emptying.
Innovation Solution
A locking device for waste containers that keeps the lid closed during sudden jerks or tilting, but allows automatic opening during dumping operations, utilizing a pendulum weight mechanism and sliding block system to ensure smooth operation and prevent unintended opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking device is provided to prevent the lid from opening when the waste container is knocked over, then the container security is improved, but the automated lifting device cannot empty the container without manual unlocking
Solution Approach 1:
The locking device uses a dynamic weight-sensitive mechanism that automatically adjusts its locking state based on the container's orientation and weight distribution. When the container is tipped for emptying, the weight shift triggers automatic unlocking, while in upright position the lid remains locked for security.
Solution Approach 2:
The locking device automatically detects when the container is being tipped for emptying and unlocks without manual intervention. The system uses the container's own weight and orientation changes as triggers, eliminating the need for manual unlocking during automated emptying operations.
2Reliability
If a lock is provided to prevent unwanted access to the container, then the security against animals is improved, but the lid operation becomes more complex
Solution Approach 1:
The locking mechanism automatically engages and disengages based on the container's orientation and weight distribution, eliminating the need for manual operation. The system uses the container's own physical state changes as triggers for locking and unlocking actions.
Solution Approach 2:
The locking device responds to changes in physical parameters such as container orientation angle and weight distribution. When the container is tipped beyond a certain angle or weight threshold is reached, the locking mechanism automatically changes state from locked to unlocked.
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 locking device effectively prevents spillage and animal access during accidental tilting while allowing seamless automated emptying by ensuring the lid remains closed until intended dumping, thus enhancing both security and operational efficiency.
Implementation Method 1
The locking device allows the lid to open automatically when the waste container is tipped over by a dumping operation

AI summary
The present invention provides a locking device for a waste container that keeps the lid of the container closed when the container is knocked over on its side, as may arise from a sudden jerking or jarring motion, such as by impact with the ground, to prevent spillage of its contents. The locking device allows the lid to open automatically when the waste container is tipped over by a dumping operation. The locking device includes a sliding block slidable between a locked position and an open position, and a pendulum weight detachably attached to a magnet, when detached from the magnet, the pendulum weight blocks the sliding block from sliding to the open position. When attached to the magnet, the pendulum weight allows the sliding block to slide to the open position.
