Solution Overview
Problem
In refrigerators, heat insulating material can be discharged outside the door body when it is filled, compromising the insulation efficiency and energy performance.
Innovation Solution
The design incorporates a cover fixer mechanism that prevents heat insulating material from being discharged by securely accommodating it within the door body, using a combination of fixers and buffer members to ensure the material remains in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If heat insulating material is filled in the door body, then insulation efficiency is improved, but heat insulating material may be discharged to the outside through accommodation space for fixers
Solution Approach 1:
The patent applies nesting by placing the heat insulating material inside the door body structure, specifically within the space formed by the door panel, frame, and cover. The fixers are embedded within this nested structure, with their accommodation spaces positioned to contain the insulating material, preventing it from being discharged to the outside while maintaining insulation efficiency.
Solution Approach 2:
The cover acts as an intermediary component that seals the accommodation spaces of the fixers. By positioning the cover to close these spaces, it prevents the heat insulating material from being discharged through the fixer mounting areas, thus resolving the contradiction between maintaining insulation and preventing material discharge.
2Strength
If fixers are mounted on door panel to combine door panel to door body, then door assembly is achieved, but accommodation space for fixers may allow heat insulating material to discharge
Solution Approach 1:
The fixers are nested within the door body structure, with their accommodation spaces positioned inside the door body rather than on the exterior. This nesting arrangement allows the fixers to provide strong mechanical attachment while containing the heat insulating material within the door body, preventing discharge.
Solution Approach 2:
The cover serves as an intermediary sealing element that closes the accommodation spaces of the fixers. This intermediary component maintains the structural integrity of the door assembly while preventing the heat insulating material from being discharged through the fixer mounting areas.
3Ease of operation
If door panel is detachably coupled to door body, then ease of assembly and disassembly is improved, but sealing and material containment may be compromised
Solution Approach 1:
The detachable coupling system is nested within the door body structure, with the fixers and their accommodation spaces positioned to contain the heat insulating material. The door panel can be detached from the door body through this nested fixer system while the heat insulating material remains contained within the door body, preventing discharge during assembly and disassembly operations.
Solution Approach 2:
The cover acts as an intermediary sealing component that maintains containment of the heat insulating material during detachable coupling operations. By sealing the accommodation spaces, it ensures that material discharge does not occur even when the door panel is being assembled or disassembled from the door body.
