Solution Overview
Problem
Sous-vide cooking apparatuses face challenges in maintaining consistent low temperatures for extended periods and efficient heat management due to inadequate insulation, leading to difficulties in controlling cooking temperature and time.
Innovation Solution
A heating apparatus with a housing, container, and rotatable cover that forms an insulating air layer, featuring a guide protrusion part and sealing members to enhance airtight performance and prevent heat leakage, while a protruding bar aids in temperature control and appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple cover structure is used, then device complexity is reduced, but insulation performance deteriorates leading to temperature inconsistency
Solution Approach 1:
The cover structure implements local quality by adding insulation layers and sealing structures at specific locations where heat loss occurs most. The guide protrusion part and sealing members are positioned at the interface between the cover and container to provide enhanced insulation and sealing exactly where needed, rather than uniformly across the entire structure.
Solution Approach 2:
The cover design employs asymmetry through the guide protrusion part that extends into the container interior on one side. This asymmetric structure creates an additional barrier against heat transfer and improves sealing at the critical interface, addressing the insulation problem without requiring a completely symmetric complex structure.
2Loss of energy
If the cover is designed to seal the container opening, then heat loss is reduced, but the structure becomes more complex requiring additional sealing components
Solution Approach 1:
The sealing function is merged with the cover structure itself. The guide protrusion part serves dual purposes: it provides mechanical guidance for cover positioning and simultaneously acts as a sealing barrier. The sealing members are integrated into the cover assembly rather than being separate components, reducing overall structural complexity while maintaining effective sealing.
3Manufacturing precision
If insulation structures are added to the cover, then temperature control improves, but manufacturing complexity increases
Solution Approach 1:
The cover structure is segmented into distinct functional layers: the main cover body, the guide protrusion part, and the sealing members. This segmentation allows each component to be manufactured separately with standard precision requirements, then assembled together. The insulation function is achieved through the layered structure rather than requiring complex monolithic manufacturing.
4Reliability
If the guide protrusion part extends into the container, then airtight performance is enhanced, but the structure becomes more complex
Solution Approach 1:
The guide protrusion part is designed with multi-functionality. It serves as a mechanical guide to position the cover correctly during opening and closing operations, simultaneously acts as a sealing barrier to prevent air and heat transfer, and provides structural support for the sealing members. This multi-functionality achieves enhanced airtight performance without proportionally increasing structural complexity.
