Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerators often lack modular and flexible solutions for providing various utilities such as water, chilled air, and mechanical power to support multiple functionalities, limiting user convenience and adaptability.
Innovation Solution
A connection system for a portable countertop unit that includes a feature module with an umbilical interface to an external appliance, allowing for the delivery of utilities like water, chilled air, and mechanical power, with a utility port and receiver for easy engagement and disengagement without tools, and a connection interface to detect and provide the required utilities to the feature module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional non-modular refrigerator system is used, then the structure is simpler and easier to manufacture, but the adaptability and flexibility for providing various utilities are limited
Solution Approach 1:
The refrigerator system is divided into a host appliance and separate interchangeable feature modules. Each module is a self-contained unit that can be independently manufactured, tested, and installed. This segmentation allows the system to adapt to different utility requirements by simply swapping modules rather than redesigning the entire system, thereby improving adaptability without proportionally increasing overall complexity.
Solution Approach 2:
The host appliance is designed with a universal interface that can accommodate multiple types of feature modules. The standardized mounting system, utility connections, and control interface allow a single host unit to support various functionalities (e.g., vacuum sealing, ice making, water dispensing) through interchangeable modules, achieving multi-functionality without requiring multiple specialized appliances.
2Ease of operation
If utilities are hardwired into the refrigerator structure, then the connection is more reliable, but the ease of operation and module interchangeability are reduced
Solution Approach 1:
Utility connections are pre-configured and pre-positioned within the host appliance and feature modules during manufacturing. The mounting system includes pre-aligned utility ports, electrical contacts, and fluid connections that automatically engage when the module is installed. This preliminary preparation ensures that users can easily install modules without complex wiring work while maintaining reliable connections through factory-tested interfaces.
Solution Approach 2:
A standardized interface assembly acts as an intermediary between the host appliance and feature modules. This interface includes standardized electrical connectors, fluid couplings, and mechanical mounting elements that provide consistent, reliable connections while enabling easy module replacement. The intermediary interface absorbs the complexity of connection management, allowing simple module installation while ensuring robust utility delivery.
3Loss of time
If the entire refrigerator is replaced to add new functionalities, then the system is more integrated and cohesive, but the loss of time and resources increase
Solution Approach 1:
The refrigerator system transitions from a static, fixed-functionality design to a dynamic, reconfigurable system. Feature modules can be added, removed, or swapped based on user needs and preferences. This dynamic capability allows the system to adapt to changing requirements over time without requiring complete replacement, reducing time loss and resource waste while maintaining functional flexibility.
Solution Approach 2:
When upgrading functionalities, users can remove obsolete feature modules and retain them for potential future use or disposal. The modular design allows selective replacement of only the necessary components rather than discarding the entire appliance. This approach recovers value from existing components and reduces the time and resources required for upgrades compared to complete system replacement.

AI summary
A connection system includes a feature module that supplies various functionalities, a portable countertop stand having an upright section that selectively receives the feature module and an umbilical connecting the portable stand to an external appliance to deliver utilities to the portable countertop stand. A utility port selectively delivers at least one utility to the feature module when engaged with the upright section. A utility receiver removably engages the utility port by hand without the use of tools and selectively receives a predetermined set of utilities when the feature module engages the upright surface. A connection interface detects when the feature module is engaged with the upright section and the predetermined utility set required by the engaged feature module. After the feature module is engaged, the connection interface prompts the utility port to release the predetermined utility set to the feature module.
