Gravity-Actuated Swivel Lock for Waste Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Waste containers lack a locking mechanism that prevents accidental opening when tipped over by animals or during waste collection, leading to spills and interference with waste removal services.
Innovation Solution
A locking mechanism with a hook and swivel component system that is locked by gravity when upright and automatically unlocks when upside down, allowing for secure closure and easy emptying into a waste removal truck.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is added to keep the container closed, then security against animals and rodents is improved, but the mechanism interferes with waste removal services that collect waste by upending the container
Solution Approach 1:
The locking mechanism transitions from a static locked state to a dynamic unlocked state based on container orientation. The swivel component with weighted portion automatically changes position when the container is upended during waste removal, causing the latching portion to disengage from the hook component and unlock the lid, thus adapting to waste removal operations while maintaining security during normal use
Solution Approach 2:
The locking mechanism uses gravitational force as a changing parameter that varies with container orientation. When the container is upright, gravity keeps the weighted portion in a position that maintains the locked state. When upended during waste removal, gravity reverses the weighted portion's position, automatically unlocking the mechanism, thus resolving the contradiction between security and adaptability
2Reliability
If a locking mechanism is added to prevent accidental opening, then protection against spills is improved, but the mechanism adds complexity to the container system
Solution Approach 1:
The locking mechanism is self-activating and self-regulating based on container orientation. The weighted portion automatically engages or disengages the latching portion from the hook component depending on whether the container is upright or upended, eliminating the need for external controls, sensors, or complex actuation systems while maintaining reliable protection against accidental opening
Solution Approach 2:
The locking mechanism extracts and utilizes the natural gravitational force acting on the container as the driving force for operation. By positioning the weighted portion to respond to gravitational changes in orientation, the mechanism achieves reliable locking/unlocking functionality without requiring motors, batteries, or complex control systems, thus improving reliability while minimizing added complexity
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 mechanism ensures the container remains closed when upright, preventing spills and animal access, and automatically opens when tipped over, facilitating efficient waste disposal without manual intervention.
Implementation Method 1
the swivel component may include a weighted portion and, when the container is in the upright position, the weighted portion may apply a downward force onto the swivel component to keep the latching portion latched onto the hook component
Implementation Method 2
the swivel component may include a weighted portion and, when the container is in the upside down position, the weighted portion may apply a downward force onto the swivel component to unlatch the latching portion from the hook component
Data Source
AI summary
A locking mechanism is disclosed. In one particular embodiment, the locking mechanism may include a hook component configured to be mounted onto an interior surface of a body of a container, a swivel component configured to engage with the hook component when the locking mechanism is locked, and a mount component to which the swivel component is rotatably mounted. The mount component may be configured to be mounted onto an interior surface of a lid of the container. When the container is in an upright position, the locking mechanism may be unlocked by applying an upward force onto the swivel component. When the container is an upside down position, the locking mechanism may unlock automatically.
