Refrigeration appliance with lighting module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigeration appliances' lighting modules often neglect the visual effect within storage compartments, and the lighting quality varies significantly due to temperature and humidity changes, leading to unstable illumination.
Innovation Solution
A lighting module design with a decorative strip and elastic members to maintain consistent light positioning, combined with a snap-fit connection and elastic components to ensure stable light quality across different environments, and a design that conceals the connecting seam for improved aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lighting module is installed in the storage compartment, then the illumination function is provided, but the visual effect and aesthetic appearance are compromised due to exposed connecting seams and inconsistent light positioning
Solution Approach 1:
The connecting seam between the decorative strip and main body is extracted and concealed within the mounting slot structure. The mounting slot is designed to cover the connecting seam, separating the aesthetic requirement from the structural connection requirement, thereby resolving the contradiction between functional installation and visual appearance.
Solution Approach 2:
The decorative strip is designed with different local qualities: the upper end portion extends into the mounting slot to conceal the connecting seam, while the decorative portion slopes outward to provide aesthetic appearance. This local differentiation allows the lighting module to simultaneously achieve functional illumination and visual appeal.
2Ease of manufacture
If the lighting module structure is simplified for easy installation, then the ease of manufacture is improved, but the stability of light positioning under temperature and humidity changes deteriorates
Solution Approach 1:
The lighting module is segmented into distinct components: a main body, a separate decorative strip, and a mounting slot structure. This segmentation allows for simplified assembly through snap-fit connections while maintaining stable light positioning through the geometric constraints of the mounting slot and positioning portions.
Solution Approach 2:
The mounting slot is pre-formed with specific geometric features including positioning portions and covering structures. These preliminary structural preparations ensure that when the lighting module is installed, the light positioning is automatically stabilized without requiring complex adjustment mechanisms, thus maintaining stability while preserving ease of manufacture.
3Shape
If the decorative strip extends into the mounting slot to conceal the connecting seam, then the visual effect is improved, but the device complexity increases
Solution Approach 1:
The decorative strip is merged with the mounting slot structure such that the upper end portion of the decorative strip extends into and becomes integrated with the mounting slot. This merging allows the decorative function and the concealing function to be achieved simultaneously without requiring separate components, thereby improving aesthetic appearance while limiting the increase in device complexity.
