Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If manual monitoring and training of bartenders is used, then operational flexibility and customer service quality are maintained, but revenue loss from overpouring and inventory waste increases
Solution Approach 1:
The patent replaces manual monitoring and training systems with an automated computer vision system. The system uses cameras to capture bartender actions and machine learning models to automatically detect overpouring incidents, eliminating the need for continuous manual supervision while reducing revenue loss from overpouring and inventory waste.
Solution Approach 2:
The system enables self-monitoring and self-correction by automatically detecting overpouring incidents and providing real-time alerts to bartenders. The machine learning model continuously learns from data to improve detection accuracy, allowing the system to operate autonomously without constant human intervention.
2Measurement precision
If real-time video analysis is implemented, then detection accuracy of overpouring is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by pre-training machine learning models on extensive datasets of bartender actions and pour scenarios. This pre-training enables the models to make rapid, accurate detections in real-time without requiring complex computational processing during actual operation, thus achieving high detection accuracy with minimal processing time.
Solution Approach 2:
The system analyzes only the critical portions of video data related to pouring actions rather than processing every frame completely. By focusing computational resources on specific moments and actions that matter most for detection, the system maintains high accuracy while reducing overall processing time and resource consumption.
3Reliability
If automated monitoring systems are deployed, then overpouring detection is improved, but implementation cost and device complexity increase
Solution Approach 1:
The system achieves multi-functionality by using a single integrated platform that combines camera capture, machine learning detection, real-time analysis, and alert generation. This universal system can detect various types of incidents including overpouring, inventory waste, and operational inefficiencies, reducing the need for multiple separate monitoring systems and lowering overall implementation complexity.
Solution Approach 2:
The patent introduces an intermediary software layer that connects existing camera systems with the monitoring and alerting functionality. This intermediary component simplifies integration by working with standard video infrastructure rather than requiring custom hardware installations, thereby reducing implementation complexity while maintaining high detection reliability.
Data Source
AI summary
A data processing system implements obtaining invoice information from a point-of-sale system identifying drinks ordered from a bar; obtaining video content from a video monitoring system that captures a bartender as the bartender is making drinks; analyzing the invoice information and the video content using a multimodal model trained to identify discrepancies between the drinks made by the bartender and the drinks ordered, the multimodal model being trained to output incident information identifying the bartender who made the drinks, ingredients used to make the drinks, and discrepancies between the drinks made by the bartender and the drinks ordered; generating one or more alerts to one or more members of staff identifying the discrepancies between the drinks made and the drinks ordered; and sending the one or more alerts to one or more network-enabled computing devices of the one or more members of staff of the bar.
