Solution Overview

Problem

Conventional LED bulbs with dimmer and toning controls integrated into the bulb body compromise the overall structure and aesthetics, increasing design complexity and costs.

Innovation Solution

An LED bulb design featuring an internal control switch and an adjustable ring with a magnet, allowing for dimmer and toning control without external switches, utilizing parallel-connected LED branches of different color temperatures, where the control switch is activated by a rolling ball mechanism within a hollow guide tube, ensuring the control switch does not affect the bulb's appearance or mold design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a switch is installed on the bulb body for dimmer and toning control, then control functionality is achieved, but the overall structure is ruined and aesthetics are affected

Engineering Contradiction:
Improvecontrol functionalityVSAvoidaesthetics
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The switch is extracted from the bulb body and relocated to the power supply module. The power supply module serves as the carrier for the switch, separating the control component from the aesthetic bulb structure. This extraction resolves the contradiction by maintaining control functionality while preserving the bulb's appearance.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The switch is nested within the power supply module, which itself is contained within the bulb assembly. This hierarchical nesting allows the switch to be integrated into the overall structure without protruding from or damaging the bulb body's aesthetic appearance, while still providing accessible control functionality.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If a switch is installed on the bulb body for control, then control functionality is achieved, but difficulty in mold designing increases and costs increase

Engineering Contradiction:
Improvecontrol functionalityVSAvoidmold designing
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The switch is extracted from the bulb body structure and assigned to the power supply module. This separation means the bulb body mold does not need to accommodate switch mounting features, simplifying the mold design process and reducing manufacturing complexity while maintaining full control functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If multiple LED branches with different color temperatures are connected in parallel, then dimmer and toning control is achieved, but circuit complexity increases

Engineering Contradiction:
Improvedimmer and toning controlVSAvoidcircuit complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The power supply module serves multiple functions: it provides power to the LED branches, houses the switch for control, and manages the parallel circuit connections for different color temperature branches. This multi-functionality consolidates components and simplifies the overall circuit architecture while achieving dimmer and toning control capabilities.

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

AI summary

An LED bulb includes an LED photoelectric module having at least two branches of LED beads with different color temperatures connected in parallel, a control switch connected with one of the branches of LED beads, and an adjustment ring. A total voltage of one branch of LED beads is less than that of each of the other branches of LED beads. The control switch has a ball, the adjustment ring has a magnet, and when the adjustment ring rotates, the magnet draws the ball to roll to switch on or off the control switch. When the control switch is on, the branch of LED beads connected with the control switch is lighted up, and when the control switch is off, the branch of LED beads connected with the control switch is not lighted up.
