Waste Container Locking Device with Orientation-Based Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste container locking mechanisms either prevent automated emptying by trash removal vehicles or allow unintended opening when the container is knocked over, leading to spillage and animal access.
Innovation Solution
A locking device with a hook, locking member, and actuating mechanism that keeps the lid closed during sudden jerks or impacts but allows opening during dumping operations, featuring a detent mechanism to prevent accidental unlatching when the container is tipped over.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is provided to prevent the lid from opening when the waste container is knocked over, then the container remains closed and prevents spillage, but the automated lifting device cannot empty the container or manual unlocking is required
Solution Approach 1:
The locking device uses a dynamic actuating mechanism that changes state based on the container's orientation. When the container is tipped beyond a certain angle, gravity causes the actuating mechanism to automatically unlatch the locking member, allowing the lid to open for emptying. When upright, the mechanism maintains the locked position to prevent accidental opening.
Solution Approach 2:
The locking device responds to changes in the container's angular position parameter. The detent mechanism is designed to engage when the container is within a certain angular range (upright position) and disengage when the angle exceeds a threshold (tipping position), automatically adapting the locking state based on orientation parameters.
2Reliability
If a locking mechanism is provided to prevent unintended opening, then the lid remains secure during accidental knockdown, but the device complexity increases
Solution Approach 1:
The locking device is designed to be self-actuating based on the container's orientation. The detent mechanism automatically engages or disengages the locking member according to the container's angular position, eliminating the need for external actuators, sensors, or control systems. The mechanism uses gravity and mechanical geometry to autonomously determine when to lock or unlock.
Solution Approach 2:
The detent mechanism serves as an intermediary between the container's orientation and the locking state. It translates the angular position of the container into corresponding engagement or disengagement of the locking member, providing a simple mechanical mediation that avoids complex control systems while reliably preventing accidental opening.

AI summary
The present invention generally relates to a locking device for waste containers, particularly residential or commercial waste containers. In particular, the invention provides a waste container locking device which keeps the container closed when a sudden jerk or jarring, such as by ground impact, is applied on the container, so that the container does not open when it is accidentally knocked over, but may be opened when tipped during dumping.
