Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bubble LED lamps have high assembly costs due to ultrasonic welding and are nondetachable, lacking cost-effectiveness and reusability.
Innovation Solution
A snap-fit assembly design for bubble lamps using a decorative shell composed of an upper and lower shell body, with snap-fit connections and elastic abutting portions, allowing for detachable and reusable assembly, and a heating light source that transfers heat to generate bubbles in a bubble tube.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If ultrasonic welding is used to assemble the decorative shell, then the assembly is firm and crack-resistant, but the assembly cost is high and the shell is nondetachable
Solution Approach 1:
The decorative shell is divided into an upper shell body and a lower shell body that can be separated. The snap-fit structure allows the two parts to be divided into independent components that can be assembled and disassembled, replacing the monolithic welded structure with modular segments connected by elastic abutting portions.
Solution Approach 2:
The ultrasonic welding process (thermal-mechanical system) is replaced with a pure mechanical snap-fit connection system. The elastic abutting portions provide mechanical interlocking through elastic deformation, substituting the welding process with a simpler mechanical assembly method that requires no specialized equipment.
2Strength
If ultrasonic welding is used to assemble the decorative shell, then the assembly is firm, but the assembly process cost is high
Solution Approach 1:
The snap-fit structure is designed to be self-assembling through elastic deformation. When the upper and lower shell bodies are brought together, the elastic abutting portions automatically deform and lock into place without requiring external welding equipment or complex assembly processes, making the system self-servicing.
3Strength
If ultrasonic welding is used to assemble the decorative shell, then the assembly is firm and crack-resistant, but the decorative shell is nondetachable
Solution Approach 1:
The connection system transitions from a static permanent weld to a dynamic reversible mechanical connection. The elastic abutting portions can deform elastically to allow assembly and disassembly, providing dynamic adaptability while maintaining firm connection during normal operation. This enables the shell to transition between connected and separated states as needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The snap-fit design significantly reduces production costs, enhances assembly efficiency, and enables the lamp to be detachable and reusable while maintaining structural integrity and bubble generation.
Implementation Method 1
The heating light source is in contact with the bubble tube or a limited gap is formed between the heating light source and the bubble tube, such that heat is transferred from the heating light source to the bubble tube to generate bubbles in the bubble tube

AI summary
The disclosure provides embodiments of snap-fit bubble lamps. In some examples, a snap-fit bubble lamp includes a decorative shell, a heating light source, and a bubble tube. The decorative shell includes an upper shell body and a lower shell body in snap fit with the upper shell body, and has a top end formed with a first opening and a bottom end formed with a second opening. The heating light source is mounted in the second opening and includes a threaded lamp base, a lamp shade, and a heating filament. The bubble tube is mounted in the first opening. The heating light source transfers heat to the bubble tube to generate bubbles in the bubble tube. The decorative shell is assembled by snap fit, and the assembly structure is simplified, thus reducing the production cost and making the decorative shell detachable and reusable.
