Flexible Adhesive Illumination Pad for Beverage Bottles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for illuminating beverage bottle contents require modifying existing bottle designs or creating new ones, which is not commercially viable due to the significant investments in manufacturing plant and machinery.
Innovation Solution
A self-contained illumination device that attaches to the container without modifying it, featuring a flexible pad with a thin slit to keep electrical components dry, a reusable adhesive ring, and a compact design using recyclable and biodegradable materials, ensuring the device fits seamlessly into the bottle base and maintains functionality in wet environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional bottle designs are used without modification, then manufacturing costs are reduced, but illumination functionality cannot be achieved
Solution Approach 1:
The illumination system is segmented into a separate attachable device comprising a circuit board with LED array and power source, which can be independently manufactured and then attached to standard bottles via adhesive pads, avoiding the need to modify bottle manufacturing processes
Solution Approach 2:
An adhesive pad acts as an intermediary between the illumination device and the bottle surface, enabling attachment without modifying either the bottle design or requiring special manufacturing equipment
2Volume of moving object
If the pad is made thin to fit in bottle base recess, then compactness is improved, but liquid-tightness becomes difficult to maintain
Solution Approach 1:
The adhesive pad is constructed as a flexible thin film that can conform to the curved surface of the bottle base while maintaining sufficient thickness to provide effective sealing against liquid ingress
Solution Approach 2:
The adhesive pad is designed with a curved surface matching the spherical contour of the bottle base, allowing it to fit into the recess while maintaining continuous contact for liquid-tight sealing
3Device complexity
If electrical elements are exposed to maintain simplicity, then device complexity is reduced, but reliability in wet environments deteriorates
Solution Approach 1:
The adhesive pad serves as a flexible protective barrier that seals around the electrical elements, preventing liquid ingress while maintaining a simple overall device structure without requiring additional protective housings
4Strength
If adhesive region is made large to ensure attachment, then bonding strength is improved, but device thickness increases
Solution Approach 1:
The adhesive region is expanded in the lateral dimensions (area) rather than increasing thickness, allowing strong bonding while maintaining a thin profile that fits within the bottle base recess

AI summary
A self-contained illumination device (10) for attachment to a container, e.g. to the base of a bottle, comprises a printed circuit board (12), with LEDs (14) attached to the central region of a liquid-impervious flexible pad (11). The central region is surrounded by an annular adhesive region which is arranged to attach the pad to the container in liquid-tight manner. The pad comprises a base layer (32) of plasticised paper or PVC, covered by an adhesive layer (34) and, before attachment to the container, a peripheral layer (36) of a release paper.
