Waste Bin Closure Device with Segmented Access Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waste collection bin closure devices face challenges in providing controlled access for waste placement while ensuring efficient emptying, particularly in narrow spaces, and often suffer from structural weakening and lack of ergonomic waste collection due to integrated access doors within the emptying door.
Innovation Solution
A closure device with a covering assembly that oscillates about a support structure, allowing separate movement of the closure portion for waste placement and a wide opening during emptying, featuring auxiliary access doors for dual-sided waste collection and reduced stress on electronic devices, facilitated by selective engagement devices and electronic control units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If access doors are incorporated in the larger emptying door, then waste can be collected from the road side while keeping the emptying door closed, but the emptying door experiences structural weakening and increased weight
Solution Approach 1:
The closure device is divided into separate functional components: a covering element for the emptying door and separate access doors that are not incorporated into the emptying door structure. This segmentation prevents the structural weakening caused by integrating access doors into the emptying door while still providing controlled waste collection access.
Solution Approach 2:
The access door functionality is extracted from the emptying door structure. Instead of incorporating access doors into the emptying door, the invention provides separate access mechanisms that can operate independently, thereby preserving the structural integrity and reducing the weight of the emptying door.
2Adaptability or versatility
If access doors are incorporated in the emptying door, then electronic and electromechanical apparatuses can be installed, but the assembly experiences significant forces during tilting that reduce efficiency and reliability
Solution Approach 1:
The electronic and electromechanical apparatuses are extracted from the emptying door assembly. The invention separates the access control functionality from the emptying mechanism, so that the apparatuses are not subjected to the significant forces experienced during tilting, thereby maintaining efficiency and reliability.
Solution Approach 2:
The system is segmented into independent functional modules: the emptying door mechanism and the access control system. This segmentation ensures that electronic and electromechanical apparatuses are not exposed to the mechanical stresses of tilting, preserving their operational reliability.
3Productivity
If the large door is arranged on the road side for emptying, then the bin can be emptied efficiently, but waste collection control is lost when placed in narrow spaces
Solution Approach 1:
The closure device is segmented into a covering element for the large emptying door and separate access doors. This allows the large door to remain on the road side for efficient emptying while separate access doors provide controlled waste collection from either side, including narrow spaces.
Solution Approach 2:
The covering element is designed to be movable and adaptable. It can be positioned to cover the large opening during emptying operations while allowing separate access doors to provide controlled access for waste collection in various spatial configurations, including narrow spaces.
4Device complexity
If a single closing element provides both controlled access and wide opening for emptying, then the structure is simplified, but it cannot maintain both functions effectively
Solution Approach 1:
The closure device is divided into distinct functional elements: a covering element for the large emptying door and separate access doors. This segmentation allows each element to optimize its specific function - the covering element provides a wide opening for emptying while separate access doors provide controlled access - without compromising overall structural simplicity.
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
Enables efficient and hygienic waste collection from both sides of the bin, maintaining structural integrity and operational reliability, even in constrained spaces, with controlled access and monitoring capabilities.
Implementation Method 1
a covering element (11) having a proximal portion (11a) rotatably constrained to the support structure (4) in correspondence with a first pivoting axis (X), and a distal portion (11b) movable about the first pivoting axis (X) between a rest condition and an open condition
Implementation Method 2
an access door (13) rotatably constrained to the distal portion (11b) of the covering element (11) about a first joint axis (Y) parallel to the first pivoting axis (X), angularly movable between a rest condition and an open condition
Implementation Method 3
The selective engagement devices (20) are configured to switch between a locked condition and a released condition in consequence of tilting of the waste collection bin (3) between a waste collection condition and a waste emptying condition
