Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee extraction methods, such as coffee makers and hand drip methods, face issues like decreased taste and fragrance over time, inefficient extraction of coffee ingredients, and the need for manual water control, making it difficult for users to achieve optimal coffee flavor and convenience.
Innovation Solution
An auto coffee drip apparatus with a housing, dripper tray module, drip head module, and boiler module that automatically calculates and controls water flow and temperature for optimal coffee extraction, featuring a rotary drive unit and lifting drive unit to adjust the nozzle height and water injection pattern, allowing for precise and efficient coffee brewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If coffee is extracted using all water supplied to the tank over a long period, then the coffee pot is filled with extraction liquid, but harmful ingredients are extracted and miscellaneous taste is mixed with the extraction liquid
Solution Approach 1:
The extraction process is divided into multiple stages with periodic water supply interruptions. The control unit stops water supply at predetermined time points during extraction, allowing the system to pause and drain intermediate extraction liquid. This periodic action prevents continuous extraction that would otherwise extract harmful ingredients and miscellaneous tastes from coffee grounds.
Solution Approach 2:
The system discards intermediate extraction liquid that contains harmful ingredients and miscellaneous tastes by draining it through the drain hole. By selectively removing this intermediate liquid and continuing extraction only with fresh water, the system recovers pure coffee extraction while eliminating harmful components.
2Productivity
If water is continuously supplied to coffee powders during extraction, then extraction liquid is discharged to the coffee pot, but efficient ingredients are not sufficiently extracted
Solution Approach 1:
The control unit implements periodic water supply interruptions during extraction, stopping water flow at predetermined time points. This allows coffee grounds to rest and reabsorb water, improving the extraction efficiency of effective ingredients. The periodic action ensures thorough saturation of coffee grounds before continuing the extraction process.
3Adaptability or versatility
If hand drip coffee is used with manual water control, then users can adjust water injection mode, but different recipes for each person and individual skill degradation affect taste consistency
Solution Approach 1:
The control unit automatically controls water supply based on predetermined extraction recipes and parameters. By eliminating manual water injection and replacing it with automated feedback-controlled water supply, the system ensures consistent taste results without requiring user skill or individual recipe adjustments.
Solution Approach 2:
The system performs water supply control automatically without requiring user intervention. The control unit manages the entire extraction process including water supply timing, duration, and interruption points, allowing the apparatus to serve itself and eliminate the need for user expertise in hand drip techniques.
4Temperature
If coffee is kept warm in the coffee pot over a long period, then brewed coffee is maintained at constant temperature, but taste and fragrance are lowered and burnt taste occurs
Solution Approach 1:
The system discards intermediate extraction liquid that contains harmful ingredients by draining it through the drain hole. By removing this liquid before it can be heated and cause burnt taste, the system prevents fragrance loss and burnt flavor development while maintaining the ability to keep final extraction liquid warm.
