Rotational Waste Diversion for Gravity Chute Impact Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gravity chutes lack efficient waste separation mechanisms that can handle the impact of falling waste without premature failure and reduce delay times, leading to high maintenance costs and inefficient recycling processes.
Innovation Solution
A rotational mechanical device with a horizontal angled impact diversion surface, housed in a horizontal rotational housing, disperses waste impact energy over a wider surface area using transfer bearings, reducing stress on the diversion surface and controlled by a central controller for precise waste sorting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If actuators and flaps are used to divert waste, then waste separation is enabled, but the actuators experience premature failure due to impact stress
Solution Approach 1:
The patent replaces the traditional actuator-flap mechanical system with a rotating mechanical device that has a diversion surface. This new system eliminates the need for actuators to push and pull lever arms, thereby removing the source of impact stress that caused premature failure. The rotating device uses a different mechanical approach where the diversion surface can rotate to direct waste to different containers without experiencing the same stress concentrations.
Solution Approach 2:
The patent introduces a rotating mechanical device that can dynamically change the orientation of its diversion surface. Instead of using actuators that move back and forth causing stress, the system uses a rotating mechanism that can position the diversion surface at different angles to direct waste flow. This dynamic rotation allows the system to adapt waste separation without the mechanical stress of reciprocating actuators.
2Productivity
If actuators are used for waste diversion, then waste separation is achieved, but delay times increase due to slow actuator response
Solution Approach 1:
The patent replaces the slow-responding actuator system with a rotating mechanical device that can more quickly reposition its diversion surface. The rotation mechanism eliminates the delay associated with actuator response time, allowing the system to rapidly direct waste to the appropriate container and improve overall recycling throughput.
3Device complexity
If a single bin is used at the base of the chute, then the system is simple, but manual separation is required which increases cost and time
Solution Approach 1:
The patent divides the single bin into multiple separate containers for different waste types. The rotating mechanical device segments the waste stream by directing different materials to different containers based on their destination. This segmentation enables automated separation of recyclables from general waste, eliminating the need for manual sorting while maintaining system simplicity.
Solution Approach 2:
The rotating mechanical device serves multiple functions: it can direct waste to different containers, rotate to different positions, and adapt to various waste types. This multi-functional design allows a single device to handle multiple separation tasks that would otherwise require multiple separate systems, maintaining simplicity while improving separation efficiency.
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 efficient waste separation into homogeneous containers with reduced maintenance needs, minimizing mechanical wear and enhancing recycling efficiency by evenly distributing impact energy and aligning waste with selected receptacles.
Implementation Method 1
acts as a mechanical diversion device which evenly disperses the waste deposit impact energy over a wider surface area, thereby reducing stress on the angled impact diversion surface
Implementation Method 2
A problem lies in the initial separation of the recyclable waste into homogeneous genres in a corresponding receptacle... As the waste falls through the gravity chute, it picks up speed and momentum
