Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum adiabatic bodies face challenges in impact resistance, component breakage prevention, structural strength, foam fluidity, and adiabatic performance, particularly in maintaining a vacuum state and reducing heat transfer.
Innovation Solution
The design includes a first and second plate with a seal between them, a support to maintain the vacuum space, a heat transfer resistor to reduce heat transfer, and a component coupling portion, with a hinge shaft and side plate configuration that prevents damage from dynamic and static loads and ensures fluidity of the foaming liquid, enhancing structural strength and adiabatic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hinge is installed in the vacuum adiabatic body, then the device can perform opening/closing operations, but the hinge becomes vulnerable to damage from dynamic and static loads
Solution Approach 1:
A hinge shaft is introduced as an intermediary element that extends from the outside of the vacuum space in the depth direction. The hinge shaft serves as a mediator that separates the functional requirement (opening/closing operation) from the vulnerable component (hinge), allowing the hinge to rotate around the shaft while the shaft itself bears the structural loads, thereby protecting the hinge from direct exposure to dynamic and static loads.
2Adaptability or versatility
If components are arranged in the vacuum adiabatic body, then functionality is achieved, but components are susceptible to breakage from external loads
Solution Approach 1:
The hinge shaft extends in the depth direction (Z-axis), which is perpendicular to the height direction (Y-axis) where components are typically arranged. This dimensional arrangement allows components to be positioned such that their extension lines do not pass through the hinge shaft, creating spatial separation that reduces stress concentration and prevents component breakage while maintaining functionality.
3Strength
If the structure is reinforced to improve impact resistance, then component breakage is prevented, but adiabatic performance may be compromised
Solution Approach 1:
The hinge shaft is positioned specifically in the depth direction extending from the outside of the vacuum space, creating a localized structural reinforcement only where needed for impact resistance. This local quality approach allows the vacuum adiabatic body to maintain its adiabatic performance in other regions while providing targeted strength enhancement at the hinge mechanism, preventing heat transfer compromise.
4Ease of manufacture
If a gap is created between the hinge shaft and component, then foaming liquid fluidity is improved, but structural strength may be reduced
Solution Approach 1:
The hinge shaft is pre-positioned such that its extension line does not coincide with the component's extension line, creating a predetermined gap before the foaming process. This preliminary action ensures that the foaming liquid can flow smoothly through the gap during manufacturing, achieving complete foam filling and curing, while the cured foam itself provides the necessary structural strength to compensate for the gap.
