Solution Overview
Problem
Existing refrigerators and freezers face issues with visually unappealing optics in the gap between the door and body, ineffective heat and cold management, and suboptimal energetic efficiency due to the design of prior sealing arrangements.
Innovation Solution
A refrigerator and freezer design featuring a profile arrangement with a web-shaped insulation element, integrated into the sealing arrangement, which is made of a polymeric material with specific dimensions and geometry to provide effective thermal resistance and visually appealing closure, while allowing for economic production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional bellows constructions are used in profile arrangements, then sealing function is achieved, but visual appeal deteriorates due to clearly visible construction in the gap area
Solution Approach 1:
The profile arrangement is divided into multiple functional segments: a sealing portion with bellows construction for sealing function, and a separate cover portion that conceals the bellows construction. This segmentation allows the visible area to have a clean, appealing appearance while the hidden portion maintains the necessary mechanical sealing functionality.
Solution Approach 2:
A cover portion acts as an intermediary element that is inserted into the profile arrangement to conceal the bellows construction in the visible gap area. This cover serves as a mediator between the functional requirement (visible sealing) and the aesthetic requirement (clean appearance), providing a visually appealing surface while the bellows construction remains hidden behind it.
2Temperature
If traditional sealing arrangements are used, then sealing function is provided, but heat and cold management deteriorates due to ineffective thermal insulation
Solution Approach 1:
The profile arrangement utilizes composite construction combining different materials with complementary properties: the bellows portion provides mechanical sealing and flexibility, while the cover portion incorporates thermally insulating materials to reduce heat transfer. This composite approach addresses both sealing and thermal insulation requirements simultaneously.
Solution Approach 2:
The invention changes the thermal parameters of the profile arrangement by incorporating materials with low thermal conductivity in the cover portion. This parameter change from purely mechanical sealing to thermally insulated sealing improves heat and cold management while reducing energy loss through the door gap.
3Use of energy by moving object
If conventional profile arrangements are used, then sealing is achieved, but energetic efficiency deteriorates due to suboptimal thermal resistance
Solution Approach 1:
The profile arrangement utilizes composite construction combining different materials with complementary properties: the bellows portion provides mechanical sealing and flexibility, while the cover portion incorporates thermally insulating materials to reduce heat transfer. This composite approach addresses both sealing and thermal insulation requirements simultaneously.
Solution Approach 2:
The invention changes the thermal parameters of the profile arrangement by incorporating materials with low thermal conductivity in the cover portion. This parameter change from purely mechanical sealing to thermally insulated sealing improves heat and cold management while reducing energy loss through the door gap.
