Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for recycling composite material waste, such as carbon fiber-reinforced and glass fiber-reinforced plastics, are costly and inefficient, often resulting in landfilling due to the inability to handle diverse waste types and the risk of releasing toxic volatile components during processing.
Innovation Solution
A mobile, hermetically sealed device with a comminuting assembly, temperature control zone, and forming unit that allows for temporary and local processing of composite material waste, incorporating a particle separator and automated regulation to manage dust and toxins, enabling recycling of various composite materials into homogeneous products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If composite material waste is processed in fixed recycling plants, then recycling capability is improved, but mobility and accessibility to different locations deteriorates
Solution Approach 1:
The recycling system is divided into separate functional modules (comminuting assembly, temperature control zone, forming unit) that can be independently configured and assembled in different locations, enabling both recycling capability and mobility
Solution Approach 2:
A hermetically sealed working chamber serves as an intermediary container that houses all processing units and can be transported to different locations, providing the mobile platform needed for accessibility while maintaining safe processing conditions
2Ease of manufacture
If composite material waste is landfilled, then disposal cost is reduced, but environmental pollution from toxic volatile components increases
Solution Approach 1:
The hermetically sealed working chamber captures toxic volatile components that would otherwise be released during comminution, converting them from harmful emissions into contained substances that can be treated or recovered, thus eliminating pollution while maintaining cost-effective disposal
Solution Approach 2:
The working chamber creates a controlled, isolated environment that prevents toxic volatile components from interacting with the external atmosphere, effectively neutralizing their harmful effects during the entire processing operation
3Productivity
If specialized recycling devices are used, then processing effectiveness is improved, but device complexity and cost increases
Solution Approach 1:
The device integrates multiple functions (comminution, temperature control, forming, dust separation) into a single multi-functional system that can process various types of composite material waste, improving processing effectiveness while avoiding the need for multiple separate specialized devices
Solution Approach 2:
The comminuting assembly, temperature control zone, forming unit, and particle separator are merged into a single integrated device with shared components and controls, reducing overall system complexity while maintaining comprehensive processing capability
4Reliability
If hermetically sealed working chamber is used, then safety and environmental protection are improved, but device complexity increases
Solution Approach 1:
A hermetically sealed working chamber constructed from modular panels or flexible sealing components provides effective containment of toxic substances while maintaining a relatively simple structural design that can be easily assembled and transported
