Refrigerator Integrated Lamp Receiving Portion for Glare-Free Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators face challenges in manufacturing complexity and glare prevention due to separate lighting assemblies, which complicate the manufacturing process and cause direct light exposure to users.
Innovation Solution
The integration of a lamp receiving portion within the inner case of the refrigerator, featuring a reflective surface that directs light emitted from a lamp towards the storage compartment, reducing the number of parts and simplifying assembly, while using a cover with a light emitting plate to prevent direct light transmission and minimize glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a separate lighting assembly is used to illuminate the storage compartment, then the lighting function is achieved, but the manufacturing complexity increases and direct light exposure causes glare
Solution Approach 1:
The patent merges the lighting assembly with the inner case by integrating the lamp receiving portion directly into the inner case structure. This eliminates the need for separate lighting assemblies and reduces manufacturing complexity while maintaining the lighting function through the reflective surface and light emitting plate integration.
Solution Approach 2:
The patent introduces a reflective surface and light emitting plate as intermediary elements between the light source and the storage compartment. These intermediaries redirect and diffuse the light, preventing direct light exposure to users while still achieving effective illumination of the storage compartment.
2Reliability
If multiple separate components are used for lighting, then the lighting function is achieved, but the number of parts increases
Solution Approach 1:
The patent combines multiple lighting components (lamp receiving portion, reflective surface, light emitting plate) into a single integrated structure formed as one piece with the inner case. This reduces the number of separate parts while maintaining all necessary lighting functions through the integrated design.
3Manufacturing precision
If a recessed lamp receiving portion is used, then the lamp is properly positioned, but the manufacturing process becomes more complex
Solution Approach 1:
The patent forms the recessed lamp receiving portion as an integral part of the inner case structure, created during the same molding process. This eliminates the need for separate manufacturing steps for the lamp receiving portion, reducing manufacturing complexity while maintaining precise lamp positioning through the integrated recess design.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the manufacturing process, reduces parts, and provides uniform indirect lighting that prevents glare, enhancing user experience by ensuring the light is evenly distributed within the storage compartment without direct exposure.
Implementation Method 1
the lamp receiving portion includes a reflective surface at a position facing the light source to reflect light emitted from the light source of the lamp, which is arranged in the receiving space, toward the storage compartment side
