Bio-waste Container Gravity Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bio-waste collection systems face challenges in ensuring controlled access and preventing container tipping during collection, particularly due to the rapid degradation and health risks associated with bio-waste, which requires specialized handling and storage solutions that maintain safety and prevent spills on public roads.
Innovation Solution
The design incorporates bio-waste containers with a gravity-activated locking mechanism that secures the lid until a predetermined angle is reached during tilting, ensuring safe access and emptying while preventing accidental opening on the ground, combined with positioning means that prevent tilting and facilitate automated collection by vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the container lid is kept locked during storage and transport, then bio-waste is protected from contamination and health risks are prevented, but the lid cannot be opened for emptying when needed
Solution Approach 1:
The locking mechanism transitions from a static locked state during storage to a dynamic unlocked state during emptying. The lid is locked by default during transport to prevent contamination, but can be unlocked when the container is tilted at the emptying station, enabling easy opening when needed.
Solution Approach 2:
The locking state of the lid is changed based on the tilting angle parameter. When the container is tilted beyond a predetermined angle during emptying operations, the locking mechanism automatically changes from locked to unlocked, allowing the lid to open while maintaining security during normal storage and transport conditions.
2Ease of operation
If the container is allowed to tilt freely during collection, then emptying is facilitated by gravity, but the container may tip over on public roads causing spills and safety hazards
Solution Approach 1:
Positioning means are provided that prevent the container from tilting beyond a predetermined angle during transport on public roads, countering any tendency toward tipping before collection. This preliminary restraint prevents harmful spills while allowing controlled tilting at the emptying station when the container is properly positioned.
Solution Approach 2:
The container's tilting capability is dynamically controlled: restricted to below the predetermined angle during transport to prevent tipping, but allowed to exceed this angle during emptying operations when the container is secured at the emptying station, enabling gravity-assisted emptying without road safety risks.
3Extent of automation
If the locking mechanism is made sensitive to tilting angle, then automatic unlocking during emptying is achieved, but the mechanism may malfunction if not precisely calibrated
Solution Approach 1:
The locking mechanism automatically detects when the container has been tilted to the predetermined angle and self-unlocks without requiring external intervention or complex calibration. The gravitational force acting on the tilted container directly actuates the unlocking mechanism, providing reliable automatic operation that is insensitive to precise calibration requirements.

AI summary
A bio-waste collection system comprising bio-waste storage containers (1) equipped with at least one access lid (2) on the top of the container (1), ground-based container positioning locations, and a collection truck (1) for these containers. The container (1) is positioned on the ground by positioning means distributed within the container and on the location, preventing the container (1) from tipping over a predetermined height when moved from its ground position. It is equipped with a lid locking/unlocking system (2) comprising a lid locking mechanism that, when closed, moves by gravity between a first locked position and a second unlocked position depending on whether the angle at which the container (1) tips is respectively less than or greater than a predetermined angle relative to the vertical.
