Refrigerator Food Container Film Layout to Eliminate Edge Shadows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food-accommodating containers in domestic refrigeration appliances face challenges in achieving a uniform decorative film application across the entire height, leading to a non-uniform appearance and potential shadow effects due to the limitations of applying decorative films only on one wall.
Innovation Solution
A food-accommodating container design featuring a lateral wall with angled planar walls connected by a curved transition, where a single, continuous decorative film is applied across the transition and adjacent areas, ensuring a stepless surface transition and preventing unwanted shadows, using a hot-stamping procedure for durable attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a decorative film is applied only to one wall of the food-accommodating container, then the application process is simpler, but the appearance becomes non-uniform and shadow effects occur at the edges
Solution Approach 1:
The lateral wall is segmented into multiple planar surfaces (first planar wall, second planar wall) connected by a curved transition. The decorative film is applied continuously across all segments, with each segment contributing to the overall uniform appearance while maintaining manufacturing simplicity through modular wall construction
Solution Approach 2:
The decorative film application is extended from a single-plane application to a multi-dimensional surface covering the curved transition and multiple angled walls. This dimensional extension eliminates edge shadows by ensuring continuous coverage across all surfaces, achieving uniform appearance without complicating the application process
2Manufacturing precision
If the decorative film is applied across the complete height of the container, then a uniform appearance is achieved, but the application becomes more difficult and time-consuming
Solution Approach 1:
The curved transition connects the planar walls smoothly, allowing the decorative film to be applied continuously across the curvature. This curved geometry enables the film to follow the surface contours naturally, achieving complete height coverage and uniform appearance while simplifying the application process through the continuous curved path
3Ease of manufacture
If the decorative film ends directly on a horizontal step in the walls, then the application area is clearly defined, but shadow effects and non-uniform appearance occur
Solution Approach 1:
The curved transition eliminates horizontal steps by creating a smooth continuous surface. The decorative film ends on this curved surface rather than on a flat step, which prevents shadow effects and maintains uniform appearance. The curvature provides a natural termination point that is both easy to position and visually precise

Function Achieved in This Case
The solution provides a visually sharp and precise decorative film application that maintains a uniform appearance, hides fingerprints and smudges, and gives a metallic appearance without using actual metallic materials, enhancing the container's hygiene and aesthetic appeal.

AI summary
A tray-shaped food-accommodating container for a domestic refrigeration appliance includes a lateral wall with a first planar wall and at least a second planar wall disposed at an angle to each other. The first and second planar walls open out at a curved transition of the lateral wall interconnecting the first and second planar walls. A decorative film, which is provided in areas of the lateral wall, is formed in one piece across the transition and areas of the first and second planar walls. A lower edge of the decorative film, which faces away from an upper edge of the container, is disposed along a stepless surface-area of the transition, along a stepless surface-area of the first planar wall and along a stepless surface-area of the second planar wall. A domestic refrigeration appliance having the container is also provided.
