Light emitting device for a container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light-emitting devices for containers, such as bottles and cups, are prone to damage due to liquid splashes exposing the circuit board, leading to instability and reliability issues.
Innovation Solution
A light-emitting device with a pad and circuit board, featuring a filling layer and bonding material layer with inward extension parts to protect the circuit board, and removable isolation paper to enhance attachment and ease of removal, while notches on the filling layer facilitate easier detachment and reduce the bonding area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the circuit board is exposed from the middle area of the pad to allow electronic components to be mounted, then the light emitting device can be assembled and function, but liquid from the container can splash onto the circuit board and cause damage
Solution Approach 1:
The filling layer is designed with different local properties: a hollow area in the middle region to expose the circuit board for component mounting, and inward extension parts at specific locations to provide liquid protection. This local differentiation allows simultaneous achievement of assembly ease and reliability.
Solution Approach 2:
The filling layer is segmented into functional zones: the hollow area for circuit board exposure and the inward extension parts for liquid barrier functionality. This segmentation allows the single filling layer to serve multiple purposes without requiring separate protective structures.
2Stability of the object's composition
If a filling layer is added to fill uneven places on the bottle to improve stability, then the stability of the container is improved, but the circuit board and electronic components become exposed and vulnerable to liquid damage
Solution Approach 1:
The filling layer combines stability-providing features (overall filling structure) with protection-providing features (inward extension parts), where different regions of the same layer serve different functions.
Solution Approach 2:
The filling layer serves multiple functions simultaneously: it fills uneven surfaces for stability, provides structural support, and creates liquid barriers through its inward extension parts, eliminating the need for separate protective components.
3Strength
If the bonding material layer is applied directly to attach the light emitting device to the container, then the attachment is secure, but removal and repositioning become difficult
Solution Approach 1:
The removable isolation paper is placed on the bonding material layer before final attachment, allowing the bonding material to be applied in advance and then protected until the correct positioning is achieved. This preliminary protection enables easy repositioning during installation.
Solution Approach 2:
The removable isolation paper acts as an intermediary protective layer between the bonding material and the external environment, allowing controlled removal and repositioning while maintaining bonding integrity when properly attached.

AI summary
The present disclosure directs to a light-emitting device configured for attachment onto a container. The device comprises a bottom layer and a filling layer atop with a central cavity to house electronic components arranged onto a circuit board, wherein the filling layer further comprises at least one extension, one cutout notch, and at least one light emitting LED arranged onto the circuit board around the extension. A bonding layer covers the top surface of the filling layer with a removable isolation paper. The circuit board and electronic components are protected form liquid corrosion and from blunt force while adhered onto the container.
