Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fluorescent lamps are used for illumination, then light is radiated in 360 degrees, but power consumption is high and luminous efficiency is low
Solution Approach 1:
The patent combines the light source, heat dissipation structure, and mounting frame into an integrated LED lighting assembly. The LED module is merged with a heat dissipation fin structure and a frame that includes clamping portions for direct mounting on the display cabinet, eliminating the need for separate components and reducing overall system complexity while improving energy efficiency.
Solution Approach 2:
The patent changes the lighting technology parameter from fluorescent to LED, which fundamentally alters the energy consumption characteristics. LEDs consume significantly less power while providing directional illumination, changing the operating parameters of the lighting system to achieve both energy savings and improved light distribution control.
2Illumination intensity
If fluorescent lamps are used, then illumination is provided, but mercury poisoning risk exists
Solution Approach 1:
The patent employs LED technology which eliminates mercury-containing materials entirely. LEDs are solid-state devices with no mercury, making them inherently safer for refrigerated environments where food storage occurs. The solution replaces hazardous fluorescent lamp materials with safe, non-toxic LED components.
3Illumination intensity
If fluorescent lamps are installed, then light is provided, but heat dissipation is insufficient
Solution Approach 1:
The patent utilizes phase change heat dissipation through extended fin structures that increase surface area for thermal radiation and convection. The heat dissipation portion features multiple fins that extend outward, creating large surface area for efficient heat transfer from the LED junction to the surrounding air, effectively managing thermal energy without compromising light output.
4Loss of information
If price tags are placed at the front end of shelf plate, then product information is displayed, but maintenance work becomes inconvenient
Solution Approach 1:
The patent segments the lighting function from the shelf structure by providing a dedicated lighting assembly with integrated heat dissipation and mounting features. The lighting module can be independently removed and replaced without disturbing price tags or shelf components, allowing separate maintenance of lighting and pricing systems.
Solution Approach 2:
The patent introduces a frame structure with clamping portions as an intermediary mounting mechanism. This frame serves as a mediator between the lighting module and the display cabinet, allowing the light to be securely mounted while maintaining easy access for removal and replacement during maintenance, without interfering with price tag placement.

AI summary
The present invention provides an integrated lighting apparatus including a main frame constructed by at least a first frame wall, a second frame wall adjacent to the first frame wall and a third frame wall adjacent to the second frame wall and opposite to the first frame wall. The first, second and third frame walls define an interior space for receiving a lighting device therein. The main frame is integrated with a heat-dissipating portion extending from a first side of the first frame wall. The interior space is covered with the lampshade. Through the heat-dissipating portion, the lighting apparatus is detachably combined with the refrigerated display cabinet in a simple and convenient manner.
