Solution Overview
Problem
Existing refrigerated display cases face challenges in achieving a stable construction with simple mounting of cover panels and cooling components while maintaining efficient cooling functionality.
Innovation Solution
The introduction of C-shaped intermediate frames with distinct horizontal and vertical struts, along with hat-shaped cross-sections, allows for increased stability and adaptable installation options, enabling efficient mounting and cooling functionality through a stable connection system using fastening pieces and thermally insulating elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If C-shaped side frames with high carrying capacity are used, then stability is improved, but device complexity increases due to multiple frame components
Solution Approach 1:
The frame structure is divided into C-shaped side frames and C-shaped intermediate frames as separate modular components. Each frame type serves specific structural purposes, allowing independent manufacturing and assembly while collectively providing enhanced stability without requiring a monolithic complex structure.
Solution Approach 2:
C-shaped intermediate frames are introduced as intermediary elements between the C-shaped side frames. These intermediate frames act as mediators that connect and reinforce the overall structure, distributing loads and improving stability while maintaining modular simplicity through standardized connection mechanisms.
2Adaptability or versatility
If multiple C-shaped frames are introduced, then installation adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
Both C-shaped side frames and C-shaped intermediate frames are designed with universal features including hat-shaped cross-sections, standardized feet configurations, and compatible connection interfaces. This universality allows the same basic frame design to serve multiple functions and installation scenarios, reducing the need for custom-manufactured components while maintaining installation adaptability.
Solution Approach 2:
The frame structure utilizes parameter variations such as different orientations of hat-shaped cross-sections (open toward top, bottom, or sides), adjustable feet positions, and modular panel configurations. These parameter changes enable adaptable installation options from a standardized frame design, allowing customization through configuration rather than manufacturing different component types.
3Loss of energy
If thermally insulating elements are added to frames, then thermal insulation is improved, but device complexity increases
Solution Approach 1:
Thermally insulating elements are merged with the frame structure itself rather than being separate additions. The insulation is integrated into the frame components and panel connections, creating a unified structure that provides both mechanical support and thermal insulation functions through a single integrated design rather than multiple separate components.
Solution Approach 2:
The frame structure employs composite construction combining metal profile elements (for structural strength) with thermally insulating materials (for thermal performance). This composite approach creates multi-functional components that simultaneously provide mechanical support, structural stability, and thermal insulation, reducing overall device complexity by eliminating the need for separate insulation layers and structural elements.
