Solution Overview

Problem

Existing LED light bulbs lack flexibility in controlling light output, particularly in terms of color and intensity, and do not offer easy manual adjustment for user-selectable settings.

Innovation Solution

A switchable LED light bulb configuration with a multiple switch position base and rotatable switch element that allows for selective contact with different LED activation settings, enabling manual selection of light output through rotation of the bulb base.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If LED light bulbs use fixed control activation configurations, then the device structure is simple, but the adaptability and user control over lighting options are limited

Engineering Contradiction:
Improvelight output control flexibilityVSAvoidbase structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a rotatable switch element that can be manually rotated to different positions, transforming a static base structure into a dynamic one. This rotational mechanism allows the user to select between multiple LED activation settings (different colors and intensities) by simply rotating the base, thereby improving adaptability without requiring complex electronic controls or multiple separate devices.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The base is divided into distinct functional components: a rotatable switch element with multiple switch positions, each position corresponding to different LED activation settings. This segmentation allows independent control of different LED groups, enabling flexible light output selection while keeping each switch position's internal structure relatively simple.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If LED light bulbs provide multiple color and intensity settings, then the adaptability improves, but the device complexity and operational difficulty increase

Engineering Contradiction:
Improvelight output optionsVSAvoidmanual adjustment ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The rotational switch element provides a natural, intuitive interaction mode that aligns with common user experiences (similar to rotating dials on radios or cameras). Users can easily rotate the base to cycle through different light settings without dealing with complex buttons, sliders, or digital interfaces, thereby maintaining ease of operation while providing multiple light output options.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows users to directly control light output settings through simple manual rotation, without requiring external controllers, remote devices, or complex programming. The self-contained rotational mechanism on the bulb base empowers users to independently adjust lighting preferences.

Inventive Principle:
Principle #25Self-service
