Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional beverage preparing machines lack an automatic cleaning functionality, requiring labor-intensive manual removal and reconnection of multiple connectors, which is time-consuming and prone to damage and contamination.
Innovation Solution
A dual-mode fluid connector with a rotatable element that switches between serve and clean modes, allowing for automatic cleaning and disinfection without disconnecting from material containers, using a sealing mechanism to isolate liquid flow and enable detergent circulation within the connector system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional connectors are used for transmitting liquid from material containers to tubes, then the beverage preparing machine can acquire various materials, but the machine lacks automatic cleaning functionality and requires labor-intensive manual removal and reconnection of connectors
Solution Approach 1:
The connector enables the beverage preparing machine to clean itself automatically by allowing cleaning liquid to flow through the connector's internal passage. The connector's structure with its passage and sealing mechanism enables self-cleaning without manual disassembly, resolving the contradiction between automation and ease of operation.
Solution Approach 2:
The connector serves multiple functions: it transmits liquid from material containers to tubes during beverage preparation, and simultaneously serves as a conduit for cleaning liquid circulation during automatic cleaning. This multi-functionality eliminates the need for separate cleaning procedures and manual connector handling.
2Reliability
If multiple connectors are manually removed one by one for cleaning, then the beverage preparing machine can be cleaned, but the process consumes a lot of labor time and makes the surrounding environment dirty
Solution Approach 1:
The connector enables automatic cleaning by allowing cleaning liquid to circulate through its internal passage without manual removal. This self-service cleaning mechanism maintains cleanliness while eliminating the time-consuming manual process of removing and reattaching multiple connectors.
Solution Approach 2:
The connector remains continuously connected to the material container throughout both beverage preparation and cleaning operations. The cleaning liquid flows continuously through the connector's passage, maintaining cleanliness without interrupting the connection or requiring manual handling.
3Ease of manufacture
If traditional connectors are used, then the structure is simple, but the connectors are prone to being scratched or damaged during manual handling
Solution Approach 1:
The connector's self-cleaning capability eliminates manual handling that causes scratches and damage. By enabling automatic cleaning through its internal passage, the connector maintains its structural integrity and durability while keeping the design relatively simple.
Solution Approach 2:
The cleaning liquid acts as an intermediary that cleans the connector internally without requiring physical contact or manual handling. This mediator approach prevents mechanical damage to the connector while maintaining its simple structure.
4Extent of automation
If connectors remain connected to material containers during cleaning, then automatic cleaning can be achieved, but the sealing mechanism must prevent liquid leakage
Solution Approach 1:
The sealing mechanism is extracted as a separate functional component within the connector structure. The sealing portion can be selectively positioned to seal the passage during beverage preparation or open it during cleaning, enabling automatic cleaning while maintaining connection to the material container.
Solution Approach 2:
The sealing mechanism is designed to be dynamic rather than static. It can change its sealing state based on the operational mode - sealing the passage during beverage preparation and opening it during cleaning operations. This dynamic behavior enables automatic cleaning while maintaining connection integrity.
