Household device with multiple compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In household refrigeration appliances with multiple compartments, existing technologies lack intuitive assignment of status display information to individual compartments, leading to user confusion and potential incorrect operation, especially in devices optimized for low energy consumption.
Innovation Solution
A status display system with dynamically adjustable display fields and modes, where each compartment has a dedicated display field, and operating parameters can be displayed and adjusted, with symbols and control elements clearly indicating their function, and an option to display relevant information for built-in devices like ice makers and water dispensers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single status display is used for multiple compartments, then production costs and installation work are reduced, but user understanding and correct operation become difficult
Solution Approach 1:
The status display is segmented into multiple display fields, with each field corresponding to a specific compartment. This segmentation allows the display to show information from different compartments simultaneously or alternately, making it clear which compartment's information is being displayed while maintaining a single physical display unit.
Solution Approach 2:
The patent introduces a temporal dimension to the display by enabling switching between different display modes (showing different compartments' information at different times). This allows a single display field to convey multiple pieces of information sequentially, resolving the contradiction between using one display and providing clear compartment-specific information.
2Ease of operation
If multiple status indicators are mounted adjacent to each compartment, then compartment assignment becomes immediately obvious, but production costs and installation work increase considerably
Solution Approach 1:
Multiple status indicators that would traditionally be distributed around different compartments are merged into a single centralized status display. This consolidation reduces the number of components needed and simplifies installation while maintaining clear compartment assignment through the use of multiple display fields within the single display.
Solution Approach 2:
The single status display is designed to serve multiple functions by displaying information from multiple compartments through different display fields. This multi-functional design eliminates the need for separate indicators for each compartment while providing comprehensive status information for all compartments.
3Reliability
If temperature is set too low to ensure proper cooling, then cooling reliability is improved, but energy consumption increases significantly
Solution Approach 1:
The status display provides real-time feedback to users about the actual temperature in each compartment and the target temperature settings. This feedback mechanism allows users to monitor whether the cooling is working properly and adjust settings accordingly, preventing the need to over-cool the compartments to ensure reliability.
Solution Approach 2:
The system allows dynamic adjustment of target temperature parameters for different compartments based on actual needs. Users can set appropriate target temperatures for each compartment individually, and the display shows when these targets are reached, enabling energy-efficient operation while maintaining reliable cooling.

AI summary
The household appliance comprises multiple blowers separated in housing, and a status display for displaying of operating condition information of the blower. The status display is separated into multiple display areas assigned on the blower. The arrangement of the display areas of the status display corresponds to the arrangement of the blower in the household appliance.
