Solution Overview

Problem

Existing LED decorative lights with flashing bubbles lack controller-adjustable flashing functions and programmable patterns, necessitating complex structures due to physical separation of constant-illumination and controllable branches.

Innovation Solution

Interspersing controllable flashing bubbles among constant-on LEDs, where the bubbles receive control signals at the controller's power terminals, allowing the controller to adjust flashing functions and patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If constant-illumination and controllable LED branches are physically separated and twisted together, then each branch can be controlled independently, but the light string structure becomes complex

Engineering Contradiction:
Improveindependent control capabilityVSAvoidlight string structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges constant-illumination LEDs and controllable flashing bubbles into a single integrated light string structure. Both types of LEDs are connected in parallel to the same power supply lines, eliminating the need for separate twisted branches. This integration maintains independent control capability while significantly simplifying the overall structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal light string structure that can accommodate both constant-illumination LEDs and controllable flashing bubbles within the same system. The controller is designed to handle multiple types of LED components through a unified interface, allowing the same physical structure to serve multiple lighting functions simultaneously.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Device complexity

If flashing bubbles are controlled by driver chips with fixed patterns, then the control circuit is simple, but the controller cannot adjust flashing frequencies or blinking modes

Engineering Contradiction:
Improvecontrol circuitVSAvoidflashing pattern adjustability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic control of flashing patterns through a controller that can adjust flashing frequencies and blinking modes in real-time. The controller receives external control signals that dynamically modify the operating parameters of the flashing bubbles, allowing transitions between different flashing patterns and frequencies without requiring physical circuit changes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the control parameters from fixed driver chip configurations to adjustable controller outputs. The controller can vary timing parameters, duty cycles, and flash patterns based on external signals, enabling the same hardware to produce multiple different flashing effects by simply changing electrical parameters rather than physical circuitry.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If a single control chip controls the entire circuit, then the control structure is simple, but programmable flashing patterns cannot be achieved

Engineering Contradiction:
Improvecontrol structureVSAvoidprogrammable flashing patterns
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent introduces an intermediary controller that sits between the power supply and the LED components. This controller acts as a mediator that receives external control signals and translates them into appropriate drive signals for the LEDs, enabling programmable flashing patterns without requiring the power supply itself to be complex or programmable.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention discloses an LED decorative light with controllable flashing bubbles, comprising: 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 a control signal 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 signal to achieve an adjustable flashing effect. 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.
