Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting labels struggle with limited color range, short lifespan, inability to change lighting effects, and unsightly bulky power supplies, especially when adhering to curved surfaces like bottles, due to the use of electroluminescent elements and impractical design.
Innovation Solution
A lighting label utilizing light emitting diodes (LEDs) with a flexible printed circuit and waterproof sealant, allowing for customizable colors and lighting effects, and a power supply placement within the container to maintain a sleek appearance, while adhering to curved surfaces through a multi-layered design with a light guide panel for uniform illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If electroluminescent elements are used for lighting label, then the label can illuminate, but the color range is limited and lifespan is short
Solution Approach 1:
The patent changes the fundamental parameter of the light source from electroluminescent elements to light emitting diodes (LEDs). LEDs offer extended lifespan (improving parameter 15) and the ability to produce multiple colors including RGB combinations (improving parameter 27). This parameter change resolves the contradiction by simultaneously achieving both longer duration and broader color range.
2Illumination intensity
If conventional lighting label design is used, then illumination is achieved, but the power supply is bulky and protrudes from the container
Solution Approach 1:
The patent extracts the power supply from the label structure itself and relocates it to the container body. The flexible printed circuit board allows the LEDs to be positioned on the container surface while the power supply is placed inside the container or in a separate compartment. This separation removes the bulky power supply from the visible label area (improving parameter 12) while maintaining illumination function (parameter 18).
Solution Approach 2:
The patent nests the power supply within the container structure rather than having it as a separate external component. The power supply is integrated into the container body or placed in a recessed area, creating a nested arrangement where the power supply is contained within the overall product structure. This eliminates protrusions (improving parameter 12) while maintaining illumination (parameter 18).
3Illumination intensity
If lighting label adheres to curved surface, then visual appeal is enhanced, but uniform illumination is difficult to achieve
Solution Approach 1:
The patent employs a flexible printed circuit board (FPC) to mount the LEDs and a light guide panel that can conform to curved surfaces. The FPC allows the LED array to be arranged in a flexible configuration that adapts to the container's curvature (parameter 12). The light guide panel distributes light uniformly across the curved surface, ensuring even illumination (parameter 18) despite the non-planar geometry.
4Adaptability or versatility
If multiple LEDs are used for customization, then color and effects are customizable, but device complexity increases
Solution Approach 1:
The patent implements multi-functional LEDs that can produce multiple colors (RGB LEDs) and various lighting effects (steady, blinking, fading). A single LED component performs multiple functions (parameter 35), reducing the need for separate LEDs for each color and effect. The flexible printed circuit board provides a universal platform for configuring different LED arrangements to achieve various lighting patterns, simplifying the overall device complexity (parameter 36) while maintaining versatility.

Function Achieved in This Case
The solution provides a long-lasting, reusable, and aesthetically pleasing lighting label with customizable colors and effects, effectively illuminating curved surfaces without protrusions, ensuring uniform brightness and resistance to environmental factors.
Implementation Method 1
The light guide panel connects to the LEDs and includes dots that scatter the light generated from the LEDs
Implementation Method 2
The translucent layer diffuses light and has a curved surface that matches the curved surface of the container
Data Source
AI summary
A lighting label that adheres on a curved surface of a container. The lighting label includes a translucent layer, an illuminating layer, a flexible printed circuit and a waterproof sealant. The illuminating layer includes a plurality of light emitting diodes (LEDs) and a light guide panel. The light guide panel connects to the LEDs and includes dots that scatter the light generated from the LEDs. The waterproof sealant seals an edge of the lighting label and is transparent to illuminate with the light around the edge of the lighting label.
