Integrated Sous-Vide Cooker With Vacuum Packing and Heat Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hybrid cooking appliances require separate devices for sous-vide cooking and vacuum-packing, which are inconvenient and expensive, and often lack sufficient space for all components, leading to inefficient and space-consuming setups.
Innovation Solution
A hybrid cooking appliance with integrated low-temperature cooking and vacuum-packing modules, where the low-temperature cooking unit includes a heating system and vacuum-packing module, allowing for sous-vide cooking and vacuum-packing in a single device, with a barrier to prevent heat interference between high-temperature and low-temperature cooking units and a support structure for stable vacuum-packing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices are used for sous-vide cooking and vacuum-packing, then functional reliability is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines the vacuum-packing module and low-temperature cooking unit into a single integrated device. The vacuum-packing module includes a vacuum generator and sealing heater, while the low-temperature cooking unit provides controlled heating for sous-vide cooking. This merging eliminates the need for separate vacuum-packing machines and sous-vide cookers, reducing device complexity and space requirements while maintaining functional reliability through coordinated operation of the integrated components
Solution Approach 2:
The integrated device performs multiple functions: vacuum-packing food items, low-temperature sous-vide cooking, and temperature-controlled heating. The control unit coordinates these different functions through a unified interface, allowing the single device to replace multiple specialized appliances. This multi-functionality approach maintains reliability by providing dedicated hardware for each function while reducing overall system complexity through integration
2Adaptability or versatility
If multiple appliances are installed at different positions, then functional versatility is improved, but ease of operation deteriorates due to inconvenient movement and setup
Solution Approach 1:
By integrating the vacuum-packing module and low-temperature cooking unit into a single portable device, the patent enables users to perform both vacuum-packing and sous-vide cooking at the same location. The device includes a removable container that can be taken to different positions, maintaining versatility while improving ease of operation. Users no longer need to move food between separate appliances located at different positions in the kitchen
3Volume of moving object
If high-temperature and low-temperature cooking units are placed close together, then device compactness is improved, but heat interference increases affecting temperature control precision
Solution Approach 1:
The patent introduces a heat-blocking barrier positioned between the high-temperature cooking unit and the low-temperature cooking unit. This barrier prevents heat transfer from the high-temperature unit to the low-temperature unit, eliminating heat interference that would otherwise affect temperature control precision. The barrier allows the units to be placed close together for compactness while maintaining accurate temperature control in the low-temperature sous-vide cooking unit through this thermal isolation intermediary
