Segmented Disposal Column for Underground Waste Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underfloor refuse collection devices lack an efficient mechanism for managing the opening and closing of the receptacle for waste disposal, which can lead to accidents during emptying and inefficient operation.
Innovation Solution
The device features a retractable and extendable throw-in column with movable elements that create or release a throw-in opening depending on the movement, allowing for controlled filling and emptying of the receptacle, with a drive device enabling independent or coupled movement of the column elements, and optionally includes a mechanism for portioning waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the disposal column is made retractable and extendable with movable elements, then safety and controlled access are improved, but device complexity increases
Solution Approach 1:
The disposal column is divided into multiple movable elements that can independently move relative to each other. These segmented elements work together to create or close the throw-in opening, providing controlled access while maintaining safety. The segmentation allows the system to achieve complex safety functions through simpler individual component movements.
Solution Approach 2:
The disposal column transitions from a static structure to a dynamic system with retractable and extendable elements. The movable elements can change position based on operational requirements, enabling the opening to be created or closed as needed. This dynamic capability enhances safety by allowing controlled access rather than permanent open structures.
2Productivity
If the disposal column elements move independently or coupled, then operational efficiency is improved, but device complexity increases
Solution Approach 1:
The drive device is designed to perform multiple functions: it can move disposal column elements independently when needed, or move them in a coupled manner for coordinated operation. This multi-functionality allows the system to adapt its operation mode based on the specific task requirements, improving operational efficiency without requiring entirely separate mechanisms for each mode.
3Volume of moving object
If the disposal column is divided into multiple elements, then space usage and waste portioning are improved, but manufacturing complexity increases
Solution Approach 1:
The disposal column is divided into multiple discrete elements that can be manufactured separately and then assembled. This segmentation enables better space utilization as the elements can be arranged to fit available space, and allows for portioning of waste through selective movement of individual elements. The modular nature of segmented construction actually simplifies manufacturing compared to creating a single large complex structure.
