An automated self-cleaning blending machine that can blend fresh or frozen fruits and vegetables on demand, providing customizable smoothies with automatic cleaning and sanitization cycles, and operates without an operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If smoothies are prepared at home using traditional blenders, then nutritional value is improved, but device complexity and cleanup difficulty increase
Solution Approach 1:
The blending machine integrates multiple functions including blending, self-cleaning, ingredient storage, and dispensing into a single device. The blender assembly can process various ingredients (frozen fruits, vegetables, ice) while the integrated refrigerator storage and automatic cleaning system eliminate the need for separate equipment and manual cleanup procedures.
Solution Approach 2:
The machine performs self-cleaning automatically through a cleaning fluid dispensing system that injects cleaning fluid into the blending chamber and uses the blender assembly to circulate and remove residue. This eliminates manual disassembly and cleaning, allowing the device to service itself after each use.
2Ease of operation
If smoothie shops are used, then convenience is improved, but operational costs and space requirements increase
Solution Approach 1:
The system divides the smoothie preparation function into modular components: an automated blending machine with integrated refrigerator storage for ingredients, a separate cleaning fluid reservoir, and a control system. This segmentation allows the device to operate autonomously without requiring commercial-grade equipment or significant space, reducing overhead costs while maintaining convenience.
3Reliability
If manual cleaning is performed, then hygiene is maintained, but time and effort increase
Solution Approach 1:
The cleaning system automatically performs hygiene maintenance by injecting cleaning fluid through the cup hat into the blending chamber, using the blender assembly to circulate the fluid and remove residue, and draining the mixture through a strainer. This self-cleaning process maintains hygiene standards without requiring manual intervention, saving time and effort.
4Reliability
If perishable ingredients are stored at home, then ingredient freshness is improved, but storage space and spoilage risk increase
Solution Approach 1:
The refrigerator storage unit is integrated within the blending machine structure, with ingredient containers nested inside the main device body. This nested arrangement allows fresh ingredients to be stored in a compact, dedicated refrigeration compartment without requiring separate freezer or refrigerator space, minimizing the volume occupied while maintaining ingredient freshness.

AI summary
A stand-alone automated machine for the automatic blending of drinks. The machine will generally puree materials including fresh or frozen fruits and vegetables provided in large particulate sections or chunks within a cup which is available from a neighboring refrigerator or freezer unit. The blending machine can handle all aspects of drink blending as well as automatic cleaning, sanitization, and/or sterilization cycles.
