Decorative Lighting String with Vertically Offset LED Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting strings with directly soldered LEDs on wires are prone to solder failure when bent, leading to loss of light emission due to the lack of flexible solder properties.
Innovation Solution
A lighting string package structure featuring a light-transmitting cap with guide pieces and lugs, where the LED is secured with a transparent adhesive that covers the soldering section and wire, preventing excessive bending and reinforcing the solder joint, and a vertically-offset lighting structure with conductors and a transparent adhesive to stabilize the LED assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the LED is directly soldered onto the wire, then the manufacturing process is simple, but the soldering joint fails when the wire is bent significantly
Solution Approach 1:
The patent introduces a separate lamp holder component that is distinct from the wire and LED assembly. This segmentation allows the wire to be flexible while the lamp holder provides structural support and a stable mounting point for the LED, preventing solder joint failure during bending.
Solution Approach 2:
The lamp holder acts as an intermediary component between the wire and the LED. It receives the wire and provides a dedicated mounting structure for the LED, isolating the solder joint from the mechanical stress of wire bending while maintaining electrical connection.
2Adaptability or versatility
If the wire is bent considerably, then the lighting string can be configured into any form, but the soldering joint easily fails
Solution Approach 1:
By separating the wire function from the LED mounting function through the lamp holder, the system allows the wire to be bent and configured freely while the lamp holder maintains a stable, non-bending structure for reliable LED attachment.
Solution Approach 2:
Different parts of the system have different mechanical properties: the wire remains flexible for configuration, while the lamp holder provides rigid structural support at the LED mounting location, creating local quality differentiation that resolves the contradiction between flexibility and reliability.
3Ease of manufacture
If the light source is positioned lower, then the manufacturing is simpler, but the lighting effect is reduced
Solution Approach 1:
The lamp holder elevates the LED to a higher vertical position, creating better spacing between the light source and the wire. This dimensional adjustment improves light emission by preventing wire obstruction and enhancing light distribution, while the standardized lamp holder structure keeps manufacturing simple.
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 solution enhances the flexibility of the lighting string, preventing solder failure and improving the lighting effect by securely attaching the LED to the cap, ensuring consistent light emission even when bent.
Implementation Method 1
The transparent glue covers the soldering section to adhere the soldering section to the guide trench and the two lugs, and extends around to wrap the light emitting surface of the light emitting diode
Implementation Method 2
The light-transmitting cap covers the light emitting diode, so that the light emitting diode is located at the opening, and the light emitting surface faces the interior of the body
