Dual-Reservoir Beverage Machine Water Source Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage forming systems lack flexibility in sourcing water, as they often rely on a single water supply method, limiting user configuration options and environmental adaptability.
Innovation Solution
A beverage machine with dual liquid supply reservoirs, an external and internal reservoir, allowing users to select between mains water and user-provided water, with a valve system to switch between sources, ensuring versatility in water supply options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a beverage machine uses a single water supply method, then the device complexity is reduced, but the adaptability to different environments and user configuration options are limited
Solution Approach 1:
The beverage machine is designed with a universal liquid supply system that can accept multiple types of water sources (mains water supply, bottled water, filtered water, or any other liquid source). The system includes a liquid supply component with a liquid inlet that can be connected to external sources, and an internal reservoir that can be manually filled, allowing the machine to function with various water supply methods without requiring different device configurations.
Solution Approach 2:
The water supply system is divided into separate functional components: an external liquid supply path with a liquid inlet, and an internal reservoir system with a removable reservoir. This segmentation allows users to independently configure each part according to their needs - connecting to mains water when available, or manually filling the reservoir with alternative water sources, thereby achieving adaptability without overwhelming system complexity.
2Adaptability or versatility
If a beverage machine includes both internal and external reservoirs with switching capability, then the versatility in water supply options is enhanced, but the device complexity increases
Solution Approach 1:
The liquid supply system incorporates a dynamic switching mechanism that allows the machine to transition between different water sources based on user needs or environmental conditions. The system can automatically or manually switch between mains water supply (when connected) and internal reservoir water (when reservoir is installed), providing flexible adaptability without requiring complex manual intervention for each switch.
Solution Approach 2:
The system uses an intermediary liquid supply component that acts as a mediator between the external water sources and the brewing system. This intermediary component manages the complexity of source switching by providing a unified interface - whether water comes from mains supply or manual reservoir filling, the liquid supply component handles the transition seamlessly, shielding the user from the underlying complexity.
3Ease of operation
If a beverage machine is designed to work with mains water supply, then the ease of operation is improved, but the adaptability to areas without mains water is reduced
Solution Approach 1:
The beverage machine incorporates a self-service water supply capability through the removable internal reservoir that users can manually fill with water from any source. When mains water supply is unavailable, users simply remove the reservoir, fill it with water from alternative sources (bottles, filters, containers), and reinsert it. The system automatically detects the reservoir presence and switches to this manual filling mode, maintaining ease of operation across different environments without requiring complex user intervention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to configure the machine for different environments by selecting between external and internal water sources, enhancing usability and adaptability, particularly in areas with varying water availability.
Implementation Method 1
A liquid conditioner may be arranged to heat and/or cool the liquid that is provided to the brew chamber, e.g., may include a heater tank or chiller to heat and/or cool water
Implementation Method 2
A liquid conditioner may be arranged to heat and/or cool the liquid that is provided to the brew chamber, e.g., may include a heater tank or chiller to heat and/or cool water
Implementation Method 3
The liquid supply may be configured to selectively fluidly connect either the external reservoir to the brew chamber to provide liquid from the external reservoir to the brew chamber or the internal reservoir to the brew chamber to provide liquid from the internal reservoir to the brew chamber
Data Source
AI summary
A beverage machine having internal and external liquid reservoirs. Liquid can be selectively be provided from either the internal or external reservoir to a brew chamber to form a beverage. The internal reservoir may be provided with liquid only from a mains water connection, and the external reservoir may receive liquid by pouring into the reservoir. A valve may be coupled to the internal and external reservoirs and selectively fluidly connect either of the reservoirs to the brew chamber. The external reservoir may be removable from the machine housing, and the valve may fluidly connect the internal reservoir to the brew chamber when the external reservoir is removed.
