Automatic Cup Lid Covering With Lift Control for Contamination Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-service drink machines without lid covering devices pose risks of cross-infection, inconvenience, and reduced hygiene due to manual lid application, increased operating steps, and susceptibility to external contaminants.
Innovation Solution
An automatic cup covering system for intelligent drinking bars, comprising a base, lifting device, and cup covering device, which automatically covers the cup rim with a lid after sensing the cup's placement, using sensors and motors to adjust to different cup sizes and prevent accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual lid covering is required, then device complexity is reduced, but ease of operation deteriorates and loss of time increases
Solution Approach 1:
The system enables automatic self-service operation where the machine itself performs the lid covering action. The sensor detects cup placement and automatically triggers the lid covering mechanism, eliminating the need for manual user intervention while maintaining simple overall system design
Solution Approach 2:
The lid is prepared in advance in the lid storage compartment, and the system automatically retrieves and applies it when needed. This preliminary preparation eliminates the need for users to manually handle lids, improving ease of operation without requiring complex real-time processing
2Productivity
If manual lid covering is required, then device complexity is reduced, but loss of time increases
Solution Approach 1:
The automatic detection and lid covering system operates autonomously without requiring user intervention. The sensor detects cup placement and the mechanism automatically covers the lid, significantly reducing the time required per operation and improving overall productivity
Solution Approach 2:
The system maintains continuous readiness to serve by keeping lids pre-positioned in the storage compartment. As soon as a cup is placed, the covering action immediately follows without interruption, ensuring continuous productive operation rather than requiring repeated manual intervention
3Object-affected harmful factors
If no lid covering device is provided, then device complexity is reduced, but object-affected harmful factors increase
Solution Approach 1:
The lid covering function is extracted as a separate automated mechanism distinct from the main beverage dispensing system. This dedicated lid covering device with sensor detection and mechanical application mechanism effectively prevents contamination by dust, insects, and debris while maintaining relatively simple overall system architecture
Solution Approach 2:
The automated lid covering mechanism acts as an intermediary protective barrier between the external environment and the beverage in the cup. By automatically applying the lid immediately after beverage dispensing, it prevents harmful external factors from contaminating the drink without requiring complex environmental control systems
4Reliability
If no lid covering device is provided, then device complexity is reduced, but reliability deteriorates
Solution Approach 1:
The sensor-based automatic detection system ensures reliable operation by autonomously detecting cup placement and triggering the lid covering action. This eliminates human error in the lid covering process and ensures consistent, reliable protection for every beverage served
Solution Approach 2:
The sensor provides immediate feedback when a cup is placed in the holder, automatically triggering the lid covering mechanism. This closed-loop feedback system ensures that the lid is always covered at the appropriate moment, significantly improving reliability by eliminating manual oversight errors

AI summary
An automatic cup covering system for an intelligent drinking bar has a base, a lifting device and a cup covering device. The base has a cup holder opening for receiving a cup. An end of the base away from the cup holder opening has a support. The lifting device is on the support and directly above the cup holder opening. The cup covering device is configured to cover a cup rim of the cup. The lifting device has a lifting connector that is movable, and the cup covering device is connected to the lifting connector. After receiving a drink, the cup is placed into the cup holder opening, and the lifting device causes the cup covering device to hold a cup lid and cover the cup rim with the cup lid from top to bottom.
