Solution Overview
Problem
Existing refrigerating appliances face reduced thermal insulation effectiveness due to nonuniform size and thickness distributions of thermal insulation members, which affect the matching degree with accommodating cavities, leading to suboptimal thermal insulation performance.
Innovation Solution
A refrigerating appliance design featuring a thermal insulation compartment module with two independent accommodating cavities, allowing for a compact shape and structure that simplifies the thermal insulation member's shape, improving the matching between the member and cavity, and enhancing thermal insulation through a labyrinth-shaped connection structure and varying wall thicknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single accommodating cavity is used in the thermal insulation wall, then the structure is simpler, but the thermal insulation member cannot achieve uniform size and thickness distribution, reducing thermal insulation effectiveness
Solution Approach 1:
The patent divides the single accommodating cavity into two independent accommodating cavities (first accommodating cavity and second accommodating cavity) separated by a partition wall. Each cavity contains its own thermal insulation member, allowing independent optimization of size and thickness distribution for each member to achieve uniform thermal insulation performance without requiring a single complex molded piece.
2Reliability
If the thermal insulation member has nonuniform size or thickness distributions, then manufacturing is easier, but the matching degree with the accommodating cavity is reduced, affecting thermal insulation effect
Solution Approach 1:
The patent applies different size and thickness characteristics to different thermal insulation members (first thermal insulation member and second thermal insulation member) according to their respective cavity requirements. Each member is optimized locally for its specific cavity geometry, achieving uniform thermal insulation performance through localized adaptation rather than requiring uniform precision across a single large member.
3Shape
If two independent accommodating cavities are used, then the shape and structure become more compact and matching is improved, but the device complexity increases
Solution Approach 1:
The patent combines two separate thermal insulation compartments into a single integrated module where the first housing and second housing are connected together. The partition wall serves dual purposes: separating the two cavities while also structurally connecting the housings. This merging approach achieves compact shape and improved matching while minimizing the increase in device complexity through functional integration.

AI summary
This application relates to a refrigerating appliance, including: a box body, including a storage compartment; and a thermal insulation compartment module, disposed in the storage compartment to define an accommodation compartment thermally insulated from the storage compartment, where the thermal insulation compartment module includes: a housing, having a first housing unit and a second housing unit, where a first thermal insulation member is located in a first accommodating cavity of the first housing unit, a second thermal insulation member is located in a second accommodating cavity of the second housing unit, and the first accommodating cavity is insulated from the second accommodating cavity, where one of the first housing unit and the second housing unit includes a first wall portion extending in a transverse direction of the storage compartment, the other one of the first housing unit and the second housing unit includes a second wall portion extending in a height direction of the storage compartment, and each of the first wall portion and the second wall portion defines a part of a boundary of the accommodation compartment. This application helps to improve matching between shapes and sizes of a thermal insulation member and an accommodating cavity, which is conducive to ensuring a thermal insulation effect
