Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED decorative lights with flashing bubbles lack controller-adjustable flashing features and programmable patterns, necessitating complex structures due to separate constant-illumination and controllable LED branches.
Innovation Solution
Interspersing controllable flashing bubbles among constant-on LEDs, where these bubbles receive control signals at the power terminals of a controller, allowing for adjustable flashing functions and patterns through a unified current path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate constant-illumination and controllable LED branches are used, then controllable flashing functions are achieved, but device structure becomes complex
Solution Approach 1:
The patent merges the constant-illumination LED branch and controllable LED branch into a single integrated light string structure. Both constant-on LEDs and controllable flashing bubbles are arranged in the same current path, eliminating the need for separate twisted branches. This integration maintains controllable flashing functionality while significantly simplifying the overall device structure.
Solution Approach 2:
The light string is designed with universal functionality where a single structure supports both constant illumination and controllable flashing operations. The controller can selectively activate different portions of the light string to achieve various lighting effects, making the device adaptable to multiple usage scenarios without requiring separate specialized branches.
2Adaptability or versatility
If IC chip control is used for point-by-point LED control, then rich lighting effects are achieved, but light string structure becomes complex due to physical separation requirements
Solution Approach 1:
The patent combines previously separate constant-illumination and controllable LED branches into one unified light string. The IC chip control system is integrated directly into this unified structure, allowing point-by-point control of specific LEDs within the same continuous current path, thereby achieving rich lighting effects without the complexity of physical branch separation.
Solution Approach 2:
The light string is segmented into different functional sections (constant-on LEDs and controllable flashing bubbles) that are distributed along the same current path. This segmentation allows independent control of different segments while maintaining a simplified unified structure, enabling diverse lighting effects without requiring separate physical branches.
3Device complexity
If fixed pattern flashing bubbles are used, then simple control structure is maintained, but controller-adjustable flashing patterns are lost
Solution Approach 1:
The patent implements dynamic control capabilities where the controller can adjust flashing patterns, frequencies, and modes in real-time. The controllable flashing bubbles respond to control signals from the controller, enabling variable flashing behaviors rather than fixed patterns. This dynamic control is achieved while maintaining a relatively simple overall control structure through efficient signal management.
Solution Approach 2:
The controller is designed to modify operational parameters such as flashing frequency, duration, and pattern types based on user input or pre-programmed sequences. This parameter adjustability allows the same hardware structure to produce multiple different flashing effects, enhancing versatility without requiring complex additional hardware components.

AI summary
The present invention discloses an LED decorative light with controllable flashing bubbles, including: a controller and a light string. The positive terminal and negative terminal of the controller are connected to the light string, where the controller supplies power to the light string through the positive and negative terminals while loading control signals on either/both the positive terminal and negative terminal. The light string includes a plurality of LEDs and a plurality of controllable flashing bubbles, with the controllable flashing bubbles receiving the control signals to achieve adjustable flashing effects. By interspersing controllable flashing bubbles among constant-on LEDs and enabling them to receive control signals loaded by the controller at power output terminals, the invention realizes an LED decorative light whose flashing functions or patterns can be controller-adjusted.
