Vacuum low-temperature cooker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum low-temperature cooking methods require separate devices for vacuum packaging and water heating, leading to increased manufacturing costs and complexity.
Innovation Solution
A combined vacuum low-temperature cooker with a main body featuring a heating unit, vacuum packaging unit, and control unit, connected by a connection cable for air and electrical communication, allowing for simultaneous vacuum packaging and water heating in a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices are used for vacuum packaging and water heating, then each device can be optimized for its specific function, but manufacturing costs increase and device complexity increases
Solution Approach 1:
The patent combines the vacuum packaging unit and water heating unit into a single integrated device. The vacuum packaging unit includes a chamber for vacuum sealing food, while the water heating unit includes a heating element and temperature control system. Both units share common components such as the control unit, power supply, and housing structure, thereby reducing overall device complexity and manufacturing costs while maintaining functional reliability
Solution Approach 2:
The integrated device performs multiple functions: vacuum packaging, water heating, and temperature-controlled cooking. The control unit can independently manage the vacuum packaging motor and the heating element, allowing the device to switch between different operational modes (vacuum sealing mode, heating mode, combined vacuum-cooking mode) without requiring separate dedicated devices
2Reliability
If separate devices are used for vacuum packaging and water heating, then each device can operate independently, but manufacturing costs increase and product costs increase
Solution Approach 1:
The patent integrates the vacuum packaging unit and water heating unit into a single device with shared structural components, control systems, and power supply. This consolidation reduces manufacturing costs by eliminating redundant parts and simplifying the production process, while the control unit maintains independent operation capability for each function through separate control circuits and sensors
