Solution Overview
Problem
Existing cleaning appliances for blasting surfaces with a mixed stream of pressurized gas and CO2 pellets are large, difficult to handle, and require significant storage and cooling for CO2 pellets, making them inefficient and cumbersome.
Innovation Solution
A compact cleaning appliance design that produces CO2 pellets from liquid or gaseous CO2 using a compressing device with a drive shaft oriented parallel to gravity, featuring a pre-compression and main compressing device, and a mobile configuration with a chassis and secure CO2 storage, allowing for efficient production and handling of CO2 pellets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If CO2 pellets are stored in large quantities for cleaning operations, then the cleaning appliance can operate continuously without interruption, but the storage requirements and device size increase significantly
Solution Approach 1:
The system performs preliminary action by producing CO2 pellets on-demand through a compressing device that converts liquid CO2 into pellets during operation, eliminating the need for large pre-stored quantities while ensuring continuous supply for cleaning operations
Solution Approach 2:
Liquid CO2 serves as an intermediary substance that is converted into CO2 pellets through the compressing device, allowing the system to generate solid pellets from a compact liquid storage form factor, thus reducing overall storage volume requirements
2Reliability
If CO2 pellets are stored at low temperatures to maintain stability, then the pellets remain stable and usable, but cooling systems and energy consumption increase
Solution Approach 1:
The system changes the temperature parameter by producing CO2 pellets at ambient temperatures through the compressing device, eliminating the need for continuous cooling systems and reducing energy consumption while maintaining pellet stability through controlled compression processes
3Adaptability or versatility
If the cleaning appliance is designed with all necessary components for CO2 pellet production and storage, then it becomes a self-contained unit, but the overall device size and weight increase
Solution Approach 1:
The system merges the CO2 storage and pellet production functions into a single integrated unit where the compressing device directly converts liquid CO2 from an onboard cylinder into pellets, eliminating separate storage facilities and reducing overall device weight while maintaining self-containment
